AAL G Sand appraisal well operations complete

08 July 2016

AWE Limited (ASX: AWE) advises that all operations relating to the AAL-4XST1 appraisal well have been completed and the Raniworo jack-up drilling rig was released on 7 July 2016. The AAL-4XST1 appraisal well successfully drilled and intersected the primary G Sand and secondary K Sand targets. Both reservoirs are of excellent quality and were fully cored for further analysis. Drill Stem Tests (DSTs) were performed on both reservoirs and oil flowed successfully to surface, assisted by Electrical Submersible Pumps (ESPs) which is standard procedure in heavy oil fields due to the viscosity of the oil. Logging of the well has been completed and the well has been plugged and abandoned according to Production Sharing Contract (PSC) requirements. The well program was completed within the Operator’s budget. As previously reported, the G Sand DST was conducted over a 3.5m perforated interval and exceeded expectations with an average stabilised flow rate of 828 barrels of oil per day (bopd) on a 64/64 inch choke over a nine hour period. Wellsite measurements indicated the G Sand oil to have a specific gravity of 10.7 API at 60° F. A second DST performed in the K Sand over a 6.5m perforated interval recorded initial oil flow rates of 1120 bopd on a 64/64 inch choke, consistent with previous tests at AAL-3X. However, mechanical failure of a down-hole sand screen prevented the DST from running to conclusion and a stabilised flow rate could not be achieved. Following the mechanical failure, the DST continued for five hours with oil flow rates varying from 536 to 1959 bopd. Though disappointed not to complete the full K Sand DST work program, the Joint Venture determined that sufficient data had been obtained to meet all objectives of the well and therefore a decision was made to plug and abandon the well as planned. Oil samples were recovered for further testing and wellsite measurements indicated the K Sand oil to have a specific gravity of 13.1 API at 60° F, consistent with previous tests at AAL-3X. The Joint Venture will undertake technical analysis and evaluation of this newly acquired data to be incorporated in Development Plan studies for the G Sand reservoir, which could be developed in conjunction with the already approved K Sand development. The Northwest Natuna PSC is located offshore Indonesia in the Natuna Sea and includes the Ande Ande Lumut (AAL) oil project. The AAL project comprises the K Sand reservoir (101 million barrels gross recoverable oil, net 24.3 million barrels of 2P Reserves and 1.7 million barrels 2C Contingent Resources to AWE) and the underlying G Sand reservoir. The AAL-4XST1 appraisal well targeted the G Sand reservoir, which is estimated to contain 289 million barrels gross oil in place with 36 million barrels gross recoverable oil (net 8.4 million barrels 2C Contingent Resources to AWE).

Drilling on South Pars

The first well in phases six-eight of Iran’s South Pars gas development in the Persian Gulf has been spudded by Statoil as operator for the offshore part of this project. Each of the 30 producers embraced by the programme will be drilled to a measured length of about 4,000 metres. The Rani Woro rig arrived at the drilling location on 25 January and spudded the day after. “That’s initiated an important new phase in the South Pars development,” says well manager Per Haaland in Statoil’s project team. Chartered by Statoil in 2003 for up to three years, Rani Woro is owned by Indonesia’s PT Apexindo Pratama Duta in Jakarta. Iran’s Pars Oil & Gas Company (POGC), which is in overall charge of the whole South Pars development, has a five-year contract with Japan Drilling Company. This covers the charter for Sagadrill 2, which is being chartered on to Statoil for up to three years. The first of three jackets for the wellhead platforms covered by phases six-eight was installed on the field on 5 January, and the other two are currently being completed. Rune Mordal, project manager for platform construction, confirms that the second jacket is due to be transported to the field in late January or early February. Sagadrill 2 is scheduled to spud its first well as soon as jacket number two has been installed.

DSIC begins construction of 'Ayu' jackup rig

Dalian Shipbuilding Industry Offshore Co. Ltd (DSIC) has announced that the shipyard successfully began construction of a DSJ400 jackup rig on 9th May 2014. The DSJ400-01 jackup rig has been ordered by Summit Drilling International Ltd and will be managed by PT Apexindo of Indonesia upon completion and named ‘Ayu’. The unit is a 400 ft jackup rig equipped with a drilling system that has a 1000 tons capacity. The units is the first ever DSJ400 rig to be constructed, with a project team from DNV GL overseeing the construction.

AAL JV spuds G Sand appraisal well

AWE Limited (ASX: AWE) advises that the Operator of the Northwest Natuna PSC, Santos Limited (ASX: STO), has confirmed that the AAL-4X appraisal well was spudded successfully at 20:00 hours (8.00pm) AEDT on 14 May 2016. As at 09:00 hours (9.00am) AEDT Monday 16 May, the well was at 200m Total Vertical Depth Sub Sea (TVDSS) in a 24 inch hole. The AAL-4X well will be drilled to a planned maximum total depth of 1,232m TVDSS and is forecast to take approximately 48 days to complete. The well is being drilled in water depth of approximately 72m using the Raniworo jack-up drilling rig. The Northwest Natuna PSC is located offshore Indonesia and includes the Ande Ande Lumut (AAL) oil project. The AAL project comprises the K Sand reservoir (101 million barrels gross recoverable oil, net 24.3 million barrels of 2P Reserves to AWE) and the underlying G Sand reservoir. The AAL-4X appraisal well is targeting the G Sand reservoir, which is estimated to contain 289 million barrels gross oil in place with 36 million barrels gross recoverable oil (net 10 million barrels 2C Resources to AWE). Appraisal of the G Sand will facilitate the preparation of Plan of Development for this resource, which could be developed in conjunction with the already approved K Sand development.

AAL G Sand appraisal well drilling update

AWE Limited (ASX: AWE) has been advised by the Operator of the AAL-4X appraisal well, Santos Limited, that due to a mechanical obstruction in the well bore the proposed Drill Stem Tests (DST) in the K-sand and G-sand reservoirs cannot be completed in the current hole. The AAL joint venture is now planning to commence sidetrack operations to allow completion of the project scope and complete the planned DSTs. Prior to the obstruction, the well had successfully achieved all other objectives of the AAL-4X well, having intersected oil-bearing sands in both the primary G Sand and secondary K-sand objectives. The evaluation programme has successfully acquired all planned wireline logs, pressure data and oil samples from both reservoirs and also recovered approximately 63m of full core across the two reservoirs. The data acquired to date has provided significant new information to further the development planning of the K-sand reservoir and to assist with the development potential of the Gsand reservoir. The AAL-4X well was drilled to a maximum total depth of 1,246m TVDSS and was forecast to take approximately 48 days to complete. The well is being drilled in water depth of approximately 72m using the Raniworo jack-up drilling rig. The AAL-4X well is still expected to be completed within the Operator's budget, as the well has been drilled in a shorter timeframe than planned. The Northwest Natuna PSC is located offshore Indonesia in the Natuna Sea and includes the Ande Ande Lumut (AAL) oil project. The AAL project comprises the K Sand reservoir (101 million barrels gross recoverable oil, net 24.3 million barrels of 2P Reserves to AWE) and the underlying G Sand reservoir. The AAL-4X appraisal well is targeting the G Sand reservoir, which is estimated to contain 289 million barrels gross oil in place with 36 million barrels gross recoverable oil (net 10 million barrels 2C Resources to AWE). Appraisal of the G Sand will facilitate the preparation of Plan of Development for this resource, which could be developed in conjunction with the already approved K Sand development.
