Dec. 2012 - Coastal Energy recently tested a three stage pilot hydraulic fracturing program in the Bua Ban South A-1 well. The fracked zones flowed back oil at a combined rate of 800 Bopd under natural conditions during well cleanup. Plans call for the well to be re-completed with an electric submersible pump for long term production testing. Next, the company will focus its efforts on the Bua Ban South A-3 sidetrack well in an effort to improve recovery rates. If successful, Coastal will continue the fracking program in order to unlock the full potential of the Songkhla Basin which is characterized by sands with lower porosity and permeability.

Nov. 2011 - Coastal Energy has successfully completed drilling of the first horizontal development well at Bua Ban North A-10 and first production is set to begin before the end of November once the MOPU installation is complete. Drilled into the Miocene reservoir on the western side of the field, the well encountered 1,185 feet of high quality net pay in the horizontal section; the lateral section was drilled at approximately 3,695 feet TVD, which is 130 feet above the known water level. A submersible pump was installed. Installation of the MOPU is expected to be completed by the end of the week. Coastal plans to spud the Bua Ban North A-11 well next, which will be drilled down the high structural fault plane of the western fault block. The Bua Ban field is located on Block G5/43 in the Gulf of Thailand. Coastal Energy wholly owns and operates the block.

Nov. 2011 - Coastal Energy has reached a total depth of 4,625 feet (1,410 meters) in the Bua Ban North A-09 well, situated on the western flank of the Bua Ban North A field. The A-09 well encountered about 42 feet (13 meters) of net pay in the Lower Miocene sand with 28 percent average porosity. The data from this well further confirms that the Bua Ban North A & B fields are connected on the western side of the structure. Coastal said that this well has provided the necessary confirmatory information to construct a centrally located permanent production facility, to be located between the A & B fields. The A-09 well will be plugged and abandoned due to the long reach of the well. Coastal will re-drill the well from the new central production facility. The company will now spud the A-10 well, which is a horizontal well in the western fault block, to improve production rates and ultimate recoveries. The Bua Ban field is located on Block G5/43 in the Gulf of Thailand. Coastal Energy wholly owns and operates the block.

Oct. 2011 - Coastal Energy has successfully appraised the Bua Ban North A-08 well. The well reached a depth of 3,860 feet (1,177 meters) on the western flank of the Bua Ban North A field. Well A-08 encountered 61 feet (19 meters) of net pay in the Lower Miocene sand with 27 percent average porosity. Pressure data indicates that this northern extension of Bua Ban North A shares a common oil water contact with the western flank of the Bua Ban North B field. The combined area is estimated to cover 1,700 acres. The Bua Ban field is located on Block G5/43 in the Gulf of Thailand. Coastal Energy wholly owns and operates the block.

Aug. 2011 - Coastal Energy has completed a production test for two additional wells at Bua Ban North B, and an appraisal well at Songkhla H. The Bua Ban North B-05 well was completed using an electric submersible pump and is currently producing 2,500 bopd from the Miocene interval. While the Bua Ban North B-01 well, also completed using an ESP, is currently producing 600 bopd from the Oligocene interval. Coastal stated that total production from the Bua Ban North field is averaging about 7,100 bopd. The company completed the B-07 water injection well and expects to complete the three remaining producing wells by the end of August. The Songkhla H-01 sidetrack reached a total depth of 9,140 feet (2,786 meters) TVD and down dip from the original well bore to determine the extent of the field. The well encountered 30 feet (9 meters) of net water bearing sand in the Lower Oligocene interval. Pressure data has confirmed the field limit is consistent with internal estimates based on seismic data. The Bua Ban field is located on Block G5/43 in the Gulf of Thailand. Coastal Energy wholly owns and operates the block.

Jul. 2011 - Coastal Energy has successfully drilled an exploratory well at Songkhla H. The Songkhla H-01 reached a total depth of 9,256 feet (2,821 meters) TVD, encountering 32 feet (10 meters) of net pay with 20% porosity in the Oligocene interval. A drill stem test was performed, and the well produced 1,000 bopd with minimal initial pressure drawdown of the reservoir. Coastal stated the crude has an API gravity of 29 degrees. The well has the potential to produce in excess of 3,000 bopd using an electric ESP. The oeprator also spudded an appraisal to delineate the reservoir. Songhkla is located on Block G5/43, and the field is wholly owned and operated by Coastal Energy.

Jun. 2011 - Coastal Energy announced that the Bua Ban North B-06 well encountered 69 feet (21 meters) of net pay with 28% porosity in the Miocene interval. Modular Dynamic Testing pressure analysis confirms that the well is in communication with the B-02 and B-04 wells, and oil samples recovered have an API gravity of 36 degrees. The B-06 well also found 17 feet (5 meters) of net pay with 22% porosity in the Eocene in the western upthrown fault block, referred to as the Bua Ban North Terrace. Coastal stated this is the highest porosity Eocene pay zone encountered in the basin. Coastal will now drill an additional well, B-07, to confirm the MDT data that indicate an oil water contact lies at 3,825 feet (1,166 meters). If so, the B-07 well might be used as a water injector. The company will then drill well B-08 on the eastern side of the field and northeast of the B-03 well to further evaluate the full extent of this closure. The Bua Ban field is located on Block G5/43 in the Gulf of Thailand. Coastal Energy wholly owns and operates the block.

May. 2011 - Coastal Energy has found additional pay in the Bua Ban field offshore Thailand. The Bua Ban North B-05 exploration well was drilled to 7,600 TVD, encountering 178 feet (54 meters) of net pay in the Miocene objective with average porosity of 27%. Currently, the well is being cased and then suspended pending the arrival of testing equipment. The company then plans to spud the B-04 well to appraise the Miocene reservoir updip from the discovery in the B-01 well. The Bua Ban field is located on Block G5/43 in the Gulf of Thailand. Coastal Energy wholly owns and operates the block.

May. 2011 - Coastal Energy encountered 62 feet (19 meters) of net pay in the Miocene objective of the Bua Ban North B-02 well. The well was drilled to a total vertical depth of 6,513 feet (1,985 meters). B-02 also tested the Eocene interval and encountered 150 feet (46 meters) of net sand with 19% average porosity. The B-02 was cased and suspended pending the arrival of testing equipment, reported Coastal Energy. Additionally, conductor pipe has been set on the B-03 well, which is testing the Miocene in a separate fault block due east from the B-02 well. The Bua Ban field is located on Block G5/43 in the Gulf of Thailand. Coastal Energy wholly owns and operates the block.

Apr. 2011 - Coastal Energy has successfully drilled the Bua Ban North B-01 exploration well offshore Thailand. The well was drilled to a total vertical depth of 7,960 feet (2,426 meters), encountering 28 feet (8 meters) of net pay in the Upper Oligocene with 23% average porosity and 29 feet (9 meters) of net pay in the Lower Oligocene with 16% average porosity. Coastal estimates that this fault block contains a total of 13 million barrels of oil-in-place across these two intervals. The B-01 well also encountered good oil shows in three zones in the Miocene level. Coastal has now spud the Bua Ban North B-02 well to test two Miocene intervals in an optimal structural position. The Bua Ban field is located on Block G5/43 in the Gulf of Thailand. Coastal Energy wholly owns and operates the block.

Apr. 2011 - Coastal Energy has hit pay in its Bua Ban North A-03 exploration well. The well was drilled to a total depth of 5,346 feet (1,629 meters) and made a discovery in the Miocene interval, encountering about 125 feet (38 meters) of net pay with 28% average porosity. The A-03 well tested a fault block which is south of and deeper than the Miocene discoveries in the A-01 and A-04 wells. Coastal predicts that this fault block holds nearly 20 million barrels of oil-in-place. The company plans to suspend the well and then complete it with a workover rig once the MOPU arrives on location in mid-May to begin production testing. The Bua Ban field is located on Block G5/43 in the Gulf of Thailand. Coastal Energy wholly owns and operates the block.

Mar. 2011 - Coastal Energy announced that its Bua Ban North A-02 exploration well was drilled to a depth of 8,100 feet (2,469 meters) into an upthrown fault block adjacent to the recent discovery in the Bua Ban North A-01 well. The A-02 well encountered 205 feet (62 meters) of net sand in the Eocene interval with 16% average porosity. The Eocene interval in the A-02 well appears to have good reservoir characteristics, and formation pressure data obtained from wireline logging indicate an oil gradient. However, log results were inconclusive and fluid samples were not obtainable. Coastal Energy is uncertain of the commerciality of the well until a flow test can be conducted. The company plans to perforate and test the Eocene in the A-02 well once suitable testing facilities are installed. Following suspension of the A-02 well, the Bua Ban North A-04 well was spudded and it will test the Miocene interval in an upthrown block relative to the productive Miocene sands encountered in the A-01 well, along with a step-out of the Upper Oligocene discovery from the A-01 well. The Company plans to drill an additional two to three appraisal/development wells at Bua Ban North A following the A-04 well. Coastal is currently mobilizing an MOPU to the Bua Ban North A location which is expected to be installed in early May. Following installation of the MOPU, Coastal will begin extended production tests of the wells at Bua Ban North A. The Bua Ban field is located on Block G5/43 in the Gulf of Thailand. Coastal Energy wholly owns and operates the block.

Mar. 2011 - Coastal Energy has found net pay in the Bua Ban North A-01 exploratory well in the Gulf of Thailand. The well found 32 feet (10 meters) of net pay in the Miocene interval and 27 feet (8 meters) of net pay in the Upper Oligocene interval, both with 25% average porosity. The Eocene interval was encountered about 700 feet (213 meters) deeper than originally prognosed and contained 70 feet (21 meters) of oil bearing sands with 14% porosity; however, given the low porosity and permeability it is not expected to flow naturally, reported the operator. Coastal is mobilizing an MOPU to the site and plans to begin flow testing the well once installation of the facilities is complete. The operator has now spud the Bua Ban North A-02 well to test the Miocene, Oligocene, and Eocene targets similar to those in the A-01 well in an upthrown fault block. The Bua Ban field is located on Block G5/43 in the Gulf of Thailand. In 2003, Coastal Energy wholly owns and operates the block.

Mar. 2011 - Coastal Energy has successfully appraised the recent discovery made by the A-09 well on the Songhkla field in the Gulf of Thailand. The Songhkla A-07 sidetrack found 45 feet (14 meters) of net pay in the Lower Oligocene at 18% porosity and 33 feet (10 meters) of net pay in the Eocene at 17% porosity. The well was completed and flow tested at 800 bopd. Furthermore, production from the previously announced A-12 well has been tied-in and is flowing at a rate of 1,600 bopd. Another well on the field, A-11, is continuing to produce about 150 bopd from the Eocene interval. Coastal plans to perforate the 44 feet (13 meters) of pay in the Oligocene interval in the A-11 well with a workover unit and then tie it in to the Oligocene production. Overall, production at Songhkla has reached a rate of about 8,500 bopd. Songhkla is located on Block G5/43, and the field is wholly owned and operated by Coastal Energy.

Jan. 2011 - The Songkhla A-12 sidetrack well has made a new discovery east of the recent discovery Songkhla A-09 well. The A-12 well encountered pay zones in both the Oligocene and Eocene reservoirs. Analysis of the data indicates both reservoirs are separated from the Songkhla Main reservoir by a 400 foot (122 meter) fault. The A-12 well encountered 32 meters (105 feet) of net pay in the Oligocene section with 20% porosity and 43 feet (13 meters) of net pay in the Eocene section with 19% porosity. Coastal’s oil-in-place estimate for this newly discovered Oligocene reservoir is more than 20 million barrels. Once the well is completed, Coastal is planning to sidetrack the previously drilled Songkhla A-07 well targeting the reservoir discovered by the Songkhla A-09 well. Songkhla is located on Block G5/43, and the field is wholly owned and operated by Coastal Energy.

Dec. 2010 - Coastal Energy has made a third discovery in the Songkhla area in the Gulf of Thailand. The Songkhla North field was discovered by the A-11 well, which reached a total depth of 7,974 feet (2,430 meters). The well encountered 44 feet (13 meters) of net pay in the Lower Oligocene reservoir with 18% porosity and 69 feet (21 meters) of net pay in the Eocene reservoir with 21% average porosity. Pressure data has indicated that the A-11 well was drilled into a separate fault block and that possibly, oil-water contact in this fault block exists at 7,500 feet (2,286 meters). Further appraisal drilling is necessary at the A-11 well to assess the size of the reservoir; but, if the initial pressure data is confirmed, the operator believes the mapped closure may be about 1,700 acres and the oil in place estimate would be about 54 million barrels. Coastal plans to tie-back this discovery to existing facilities once upgrades on the Songkhla processing facilities are completed. Songkhla is located on Block G5/43, and the field is wholly owned and operated by Coastal Energy.

Oct. 2010 - Coastal Energy conducted exploratory drilling on the Bua Ban field to further establish productivity and potential trapping mechanisms in the Miocene age reservoir. The Bua Ban A-11 well was drilled to a true vertical depth of 4,500 feet (1,372 meters), encountering 50 feet (15 meters) of net pay across two intervals in the Miocene reservoir with average porosity of 25%. The A-11 well is currently producing about 300 bopd with zero water cut. The Bua Ban A-08 exploration well, drilled to test the northern limit of the Bua Ban field, encountered quality sands with some oil shows; however the sand was wet, suggesting that the well is at the down dip limit on the northern part of the structure. The well was completed as a water injector. The third well, the Bua Ban A-09 water injector was drilled and completed prior to the rig leaving the Bua Ban location. While drilling the A-09 well, 135 feet (41 meters) of the main source rock in the Lacustrine Shale was cored for further evaluation of a non-conventional play. Initial results are promising, and final core analysis is expected in 8 to 10 weeks. The Bua Ban field is located on Block G5/43 in the Gulf of Thailand. In 2003, Coastal Energy acquired 100% in the block from the Thailand government.

Oct. 2010 - The Vicksburg jackup was mobilized to the Songhkla A field to drill two appraisal wells into the Songkhla Oligocene Wedge, and then drill two appraisal wells into the Eocene reservoir. Then, processing equipment at the Songkhla facility will be upgraded in mid-November to stabilize the field's production. The field is currently flowing at a rate of 10,500 with a total combined production rate of 12,500 boepd. Located on Block G5/43 in the Gulf of Thailand, Songhkla is located in the Songkhla Basin.

Sep. 2010 - Coastal Energy reported that the Bua Ban A-10 well was drilled to a total depth of 7,474 feet (2,278 meters), encountering 130 feet (40 meter) of net pay in the Lower Oligocene reservoir with 17% average porosity. The A-10 well was drilled in to the same fault block as the A-05 well, encountering the same expanded section of the Lower Oligocene found in the A-05 well. The well was tied in to production facilities and is now producing 1,150 bopd. Two wells on the Bua Ban field, A-04 and A-07, were drilled to a depth of 7,908 and 8,122 feet (2,410 and 2,476 meters), respectively, encountering pay zones in the Lower Oligocene, as well as the Eocene reservoir. Currently, testing is being conducted in the Eocene section to evaluate the potential of the reservoir. The Bua Ban field is located on Block G5/43 in the Gulf of Thailand.

Jun. 2010 - Coastal Energy provided a logging update at the Bua Ban field: the Bua Ban A-01 well was drilled to a total depth of 7,725 feet (2,355 meters), encountering 24 feet (7 meters) of net pay in the Lower Oligocene reservoir with 16.5% average porosity. Drilled to a total depth of 7,722 feet (2,354 meters), the Bua Ban A-02 well encountered 26 feet (8 meters) of net pay in the Lower Oligocene reservoir with 16.5% average porosity. Additionally, the Bua Ban A-05 well was drilled to a total depth of 7,492 feet (2,284 meters), encountering 170 feet (52 meters) of net pay in the Upper and Lower Oligocene reservoirs with average porosity of 15%. The A-05 well encountered an expanded Lower Oligocene section containing 85 feet (26 meters) of net pay and six distinct oil reservoirs over a gross interval of 832 feet (254 meters). Coastal Energy is now performing completion activities on all three wells and plans to tie-back the wells in order to commence production. Following completion activities, Coastal will drill up to seven more development wells at Bua Ban. The Bua Ban field is located on Block G5/43 in the Gulf of Thailand, which Coastal Energy wholly owns and operates.

Feb. 2010 - The Songkhla B-02 sidetrack well reached a total depth of 11,073 feet (3,375 meters) and encountered 12 feet (4 meters) of net pay in the Lower Oligocene reservoir – roughly five additional feet than was encountered in the B-02 discovery well. Logging tests confirmed the interval was a minimum oil column of 300 feet (91 meters), but the estimated reserves do not justify a stand-alone development. Until additional tests are carried out, the wells will be plugged and abandoned. Furthermore, workover operations were completed on the A-04 well, and it is producing approximately 3,000 bopd. Currently, workover operations have started on the A-03 well to replace a pump, and the well should come back online by the end of the week. Similar operations will also be carried out on the A-01 well.

Feb. 2010 - Following successful repairs to the top drive of the Atwood Vicksburg jackup, Coastal recommenced drilling operations on the Songkhla B-02 well. Additionally, workover operations are nearing completion on the Songkhla A-04 well, and the company expects the well to come online within the next two days. Located on Block G5/43 in the Gulf of Thailand, the Songhkla field is situated in the Songkhla Basin. Coastal Energy wholly owns and operates the project.

Feb. 2010 - Reaching a total measured depth of 9,606 feet (2,928 meters), the B-02 sidetrack well encountered 7 feet (2 meters) of net pay in the Lower Oligocene reservoir. The well also encountered several hundred feet of oil shows in a fractured Lower Oligocene Lacustrine shale interval, which needs to be evaluated further to determine the reservoir's viability. The operator is drilling a sidetrack well to target a thicker section of the area that was seismically identified. Due to rig difficulties, the sidetrack well was temporarily delayed, but operations are expected to resume in roughly 10 days. Additionally, workover operations commenced on the Songkhla A-04 well and should be completed by next week. Once completed, Songkhla's A-04, A-01 and A-03 electric submersible pumps will be replaced with higher volume ESPs. The operator also stated that the Bua Ban platform was installed and hookup and commissioning operations have commenced. The platform should be finalized in April – and the Coastal Energy Resolution FSO should be ready for installation at Bua Ban in mid-April. Located on Block G5/43 in the Gulf of Thailand, Songhkla is situated in the Songkhla Basin. Coastal Energy wholly owns and operates the project.

Jan. 2010 - The Songkhla B-01 well was drilled to a total measured depth of 9,050 feet (2,758 meters), encountering oil-bearing sands in the Lower Oligocene formation, logging only 10 feet (3 meters) of net pay. Hydrocarbons identified in the Eocene formation were characterized by low porosity and permeability. Contingent upon the results of other exploration activity in the region, Coastal may return to the well at a later date for completion, but, for now, the well has been temporarily abandoned. Another well, Songkhla B-02, located on the western side of the fault block, will be drilled to fully evaluate Songkhla B. Located on Block G5/43 in the Gulf of Thailand, this prospect is situated in the Songkhla Basin. In 2003, Coastal Energy acquired 100% of the lease of the block from the Thailand government.

Nov. 2009 - The Songkhla A-08 development well on the Songkhla field, situated on Block G5/43 in the Gulf of Thailand, has been completed for Coastal Energy. The development well was drilled by Atwood Oceanics' Vicksburg jackup to a total depth of 9,112 feet (2,777 meters) and logged roughly 92 feet (28 meters) of net pay with 18% porosity in the Lower Oligcoene primary reservoir. The well is flowing at a rate of 3,500 bopd with a 3% water cut. The A-08 well is a replacement for the A-02 well, which was converted into a water injection well because of mechanical problems. The original field development plan for Songhkla consisted of drilling and completing three production wells and one water disposal well.

Oct. 2009 - Coastal has announced the completion of the Songkhla A-02 development well on Block G5/43 in the Gulf of Thailand, and has issued an operations update. The Songkhla A-02 well was drilled to a total measured depth of 8,804 feet (2,684 meters) and logged approximately 98 feet (30 meters) of net pay with 20% porosity in the Lower Oligocene primary reservoir. Completion casing has been run and the well has been perforated. The well was cleaning up and flow testing over 3,000 bopd when a sudden increase in water production occurred from a suspected channel in the cement behind the production casing. The well is currently producing 1,500 bopd. The Songkhla A-05 injection well was spud on October 4 and was drilled to a total measured depth of 8,770 feet (2,673 meters).
