Sep 17, 2012 – After battling through federal regulatory issues and environmental lawsuits, Shell’s Chukchi Sea exploration drilling program has gotten off to a rocky start. Soon after spudding the first well, the Noble Discoverer (mid-water drillship) was forced to move off location for a short time due to an encroaching ice floe. The latest setback occurred when the containment dome – used to contain uncontrolled oil flowing from a subsea wellhead – was damaged during testing. Without an operational containment dome, the company will not be able drill into oil-bearing zones. However, Shell will still be able to drill the shallow top-hole sections of several exploration wells before the short drilling season comes to an end.

Sep 20, 2012 – Xcite Energy has successfully concluded the pre-production well test in the Bentley Phase 1A work program. The test was built around two horizontal well sections (9/3b-7 and 9/3b-7Z) that represented an excess of 4,200 feet of net reservoir. Approximately 147,000 barrels of Bentley crude were produced. Results confirmed the existence of a large aquifer that should provide long term pressure support during production. Even with the aquifer in place, the oil-water ratio was far better than expected and provides important information for modeling long term oil recovery from the field. Both well bores will be suspended and kept available for use in the next phase of development. Drilling and testing were carried out by the Rowan Norway (400′ ILC). Once the test equipment on the rig has been decommissioned the rig be demobilized from the field and released back to Rowan.

Aug 17, 2012 – Talisman Energy stated that the Duart field, which was shut-in on July 26 due to a process shutdown on the host Tartan platform, remains shut-in to date. During the shut-in period, additional technical issues have come to light which are preventing the restart of gas processing on the Tartan platform. The gas process is required to support Duart production. The operator will continue to close the field until these problems are resolved. Talisman indicates that the earliest restart date is December 2012.

Aug 23, 2012 – Borders & Southern received positive results from the fluid analysis performed on samples from Well 61/17-1 located offshore the Falkland Islands. The initial condensate yield from the Darwin gas samples, as measured in a laboratory separator test, varies from 123 to 140 stb/MMscf. The API gravity of the condensate is 46 to 49 degrees. Based on the condensate yield and ongoing reservoir modeling, the Company estimates the recoverable volume of condensate to be 130 to 250 million barrels with a mid-case of 190 million barrels. The company will now move forward with the acquisition of additional 3D seismic data in 2013 and explore the best way to fund an exploration and appraisal campaign.

Ophir Energy Successfully Appraises Fortuna Discovery
Aug 23, 2012 – Ophir Energy has successfully drilled the Fortuna East-1 appraisal well in Block R offshore Equatorial Guinea. Fortuna East-1 is located approximately 4 miles (7 kilometers) east southeast of Fortuna-1. The well encountered natural gas in the eastern lobe of the Fortuna Complex as well as in a deeper exploration target Viscata. The recoverable mean resource from the eastern lobe is now estimated at 426 Bcf. A 180-foot (55-meter) gas bearing column containing a total of 131 feet (40 meters) of net pay in the primary target Late Miocene sands of the eastern lobe of the Fortuna Complex was encountered. Pressure measurements indicate communication between Fortuna-1 and Fortuna East-1.
Aug 20, 2012 – Interests in two major natural gas projects in Australia have changed hands between Royal Dutch Shell and Chevron Corporation. Shell has agreed to swap its interest 33.3-percent interest in two gas fields associated with its Wheatstone project located in Western Australia and pay $450 million in cash to Chevron. In return, Shell will receive a combined interest of 36.7-percent interest in the Browse LNG project.
Shell will now hold a 35-percent ownership in West Browse and 25-percent in East Browse. International Director for Shell Upstream, Andy Brown believes this deal with simplify the ownership of the Browse gas fields.

Aug 17, 2012 – Karoon Gas has completed repair work on a blowout preventer after more than two months, and the contracted semisub rig, Transocean Legend (mid-water semisub), can resume drilling in the Greater Poseidon area in the Browse Basin offshore Western Australia. The operator is planning to drill at the Boreas-1 well, the first of a minimum five exploration wells the consortium will drill in the Greater Poseidon area, will begin on Aug. 17. All of the five exploration wells will be drilled by the Transocean Legend, and lie in the WA-314-P, WA-315-P and WA-398-P Browse Basin permits containing the previously announced Poseidon and Kronos gas discoveries. Karoon Gas holds a 40 percent stake in WA-315-P and WA-398-P, and a 90 percent stake in WA-314-P. ConocoPhillips holds the remaining stakes in the three permits.

Borders & Southern has announced the results of the Darwin fluid sample analysis. As previously reported, well 61/17-1 encountered a good quality sandstone reservoir comprising 67.8m of net pay with an average porosity of 22%. The gas condensate reservoir was sampled at four separate levels with 3 fluid samples taken at each level.
The initial condensate yield from the Darwin gas samples, as measured in a laboratory separator test, varies from 123 to 140 stb/MMscf. The API gravity of the condensate is 46 to 49 degrees. Based on the condensate yield and ongoing reservoir modelling, the Company estimates the recoverable volume of condensate to be 130 to 250 million barrels with a mid case of 190 million barrels.
Following these positive laboratory results, the Board will approve a work programme that includes appraisal drilling of the Darwin discovery. Additional wells are necessary to confirm the initial resource estimates and establish a commercial development. In the coming months, activity will focus on a comprehensive technical evaluation of all the data collected from well 61/17-1 and a review of potential development concepts along with project economics.
These results have exciting implications for the Company’s prospect and lead inventory and particularly for those prospects in the Lower Cretaceous play fairway to the south of the Falkland Islands. Borders & Southern’s prospect inventory contains further relatively low risk structural prospects of a similar size to Darwin along with stratigraphically trapped fans of slightly higher risk but larger scale. Some of these prospects will be targeted in the next drilling phase with the objective of adding to the discovered resources of Darwin and building a core development area.
“Discussions with a seismic contractor regarding the acquisition of additional 3D seismic are in progress and we plan to have a vessel in the Falklands at the start of 2013 to commence the survey,”said Borders & Southern in a statement.
This survey will focus on similar prospects to Darwin currently outside our existing 3D area. Whilst the final costs of the 2012 drilling programme will not be fully known until after the demobilisation of the rig later in the year, the Company can state that it is fully funded for the 3D seismic acquisition and processing, the reprocessing of the Company’s 2007 3D seismic data and all the technical studies that need to be undertaken on the samples collected from the two wells.
Given the encouraging results from the Darwin well, the Company will start planning the next drilling programme, which is likely to include both exploration and appraisal wells. The company has said that the the timing of drilling will be dependent on rig availability, but “realistically this will not occur before 2014“. The Company is currently exploring the best way to fund the next phase of the programme, including the possibility of now bringing in partners.
The Parmer prospect #1 is located on Green Canyon 867, at a depth of 18,900 ft (5,760 meters), which allowed for several pressure readings and the collection of several fluid samples from Miocene sands. The data indicate a column of approximately 240 ft (73 meters) of net condensate-rich gas pay, as prospect as one of 40 ft (12 meters) of net oil pay. In the coming months, Ecopetrol and its partners will reprocess 3-D seismic data and determine a comprehensive delimitation and development plan according to these results.
The two Parmer leases (GC 823 and GC 867) are located within the Green Canyon protraction area, at a depth of approximately 4,200 ft (1,280 meters) underwater. Each covers an area of 5,760 acres (23.3 square kilometers) and is located approximately 143 miles (230 km) from Louisiana.
Ecopetrol America has a 30% interest in the Parmer Prospect. Its partners are Stone Energy, and Apache that is the prospect’s operator.
The Parmer discovery is Ecopetrol’s second deepwater discovery in the Gulf of Mexico, one of the regions with the highest oil hydrocarbon potential in the world.
The results are expected to assist in Ecopetrol S.A.’s strategy to attain a production level of 1.0 million clean barrels of oil equivalent a day by 2015, and 1.3 million clean barrels by 2020.
