Ophir Subsidiary to Participate in Starfish
Dec 13, 2012 – A subsidiary of Ophir Energy has assumed operatorship of the Offshore Accra Contract Area through a farmout agreement with Tap Oil. Under the agreement, the Accra Contractor Group consists of: Ophir Energy (20%), Afex Oil (20%), Vitol Upstream (30%), Rialto Energy (12.5%), Tap Oil (17.5%). The farmout and transfer of operatorship have been approved by Ghana National Petroleum Corporation and the Ministry of Energy. Contract terms dictate that an exploration well must be drilled before September 23, 2013 and the Group has identified the Starfish prospect as the target of that well. Starfish is a deepwater prospect that is structurally similar to the Jubilee field. It is estimated to hold P50 reserves on the order of 431 Mmbbls.
Hess Hits Pay in Pecan-1
Dec 12, 2012 – A notice of discovery was filed with the Ghana National Petroleum Corporation on behalf of Hess Corporation for the Pecan-1 exploration well. Drilled in the Deepwater Tano / Cape Three Points license, a total depth of 15,420 feet was reached and 245 net feet of oil pay was discovered in two separate intervals. An extensive logging program was carried out and the well was sidetracked to obtain additional reservoir cores. Drilling was carried out by the Stena DrillMAX (UDW drillship) in 8,245 feet of water. The rig is now in the process of suspending the well before sailing to the Cob prospect 15 miles away.
Dec 12, 2012 – Production has commenced from Jubilee Phase 1A offshore Ghana. The first production well is onstream and has helped bring total field production to over 90,000 bopd. Phase 1A consists of five production wells, three injection wells and general expansion of the existing subsea infrastructure and should take 18 months to complete. A second Phase 1A well is expected to be brought into production before the end of the year but the Sedco Energy (DW semisub) must first perform remedial work on some of the Phase 1 wells.

Pathum-1 Exploration Spuds Off Thailand
Dec 13, 2012 – Tap Oil announced the spud of its Pathum-1 exploration well in the G3/48 concession offshore Thailand. The well is being drilled by the Ensco 85 (300′ ILC) to a proposed total depth of 8,667 feet. Pathum is thought to hold perspective resources in the range of 5 million barrels. Barring any issues, the well should reach TD in a maximum of 11 days.
Dec 13, 2012 – Difficulties have plagued MEO Australia at its 100% owned Gurame prospect in the Seruway PSC off Northern Sumatra. After loosing over 100 feet of BHA in the Gurame SE-1X appraisal, the decision was made to plug back and sidetrack the well. More progress was made in Gurame SE-1XST but significant mud losses caused MEO to plug back into the liner at 9,599 feet. A 187 foot section of the Baong sands was perforated at 8,858 feet MDRT. No flow was observed and attempts to stimulate the well with nitrogen were made with no effect. The Ensco 85 (200′ ILC) will plug and abandon the well and will be released soon after.

Dec 12, 2012 – A steel cutting ceremony held at Keppel Subic Shipyard marked the start of construction of a Depletion Compression Platform (DCP) to be deployed at the Malampaya gas field near Palawan Island in the Philippines. Installation of the DCP represents Phase 3 of the Malampaya Gas-to-Power project which is led by the Philippine Department of Energy. Once complete the DCP will be stationed next to the existing Malampaya production platform. Supporting the project are Shell, as operator, and joint venture partners Chevron and Philippine National Oil Company. Keppel is responsible for building the base and topsides as well as a bridge connecting the new facility to the production platform. The DCP is expected to be installed by 2015.

Dec 12, 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.

Europe – North Sea
Dec 14, 2012 – Production testing has been completed on three initial development wells at the Breagh field in the UK North Sea. Results from the tests are in-line with reservoir stimulation models run by development partners RWE Dea and Sterling Resources. Once normalized to reflect expected the sales level of wellhead pressure, the current three well capacity is estimated at 88 Mmscfd. The newly drilled A3 well is the most prolific producer with a flow rate of 58 Mmscfd under initial production conditions. Performance of the development wells is being monitored so that future production can be optimized. Five wells are expected to be available by early May 2013 with an estimated total production capacity of 150 Mmscfd.

Dec 13, 2012 – Norwegian oil major Statoil announced Thursday that it plans to use seismic cables on the seabed to help produce 30 million additional barrels of oil from its Snorre and Grane fields. The company has signed contracts worth $160 million with U.S. firm Geospace Technologies to deliver the cables, which will be part of a permanent reservoir monitoring (PRM) program. Statoil believes the technology will allow it to better understand the reservoirs because they are stable and able to provide a more accurate picture of the subsurface than cables that are towed on the surface and which are subjected to wind, waves and currents. Statoil plans to lay more than 400 miles of seismic cables. Statoil currently recovers around 50 percent of the oil from its operated fields on the Norwegian continental shelf.

Wintershall Spuds Rodriguez
Dec 11, 2012 – The Transocean Arctic (mid-water semisub) is drilling ahead at Wintershall’s Rodriguez prospect in the Halten Terrace area off Norway’s coast. Well 6407/1-6S is seeking oil in the Middle Jurassic Garn, Ile and Tilje formations. It should take roughly 75 days to reach the planned total depth of 13,254 feet. Rodriguez is located in PL475 near the Tyrihans field and Faroe’s 2010 Maria discovery. Wintershall maintains a 50 percent operating interest in the license with Faroe Petroleum and Centrica sharing 30 and 20 percent interest respectively.

Dec 13, 2012 – A recent three well appraisal drilling program undertaken by BG Group and Ophir Energy on the Jodari field off Tanzania successfully achieved its objectives. The wells proved high quality reservoir across the field and reconfirmed the 3.4 Tcf mean recoverable resource estimate. In addition, the joint venture was able verify that high-angle drilling within Jodari may be a viable option to reduce development costs. Drilling was carried out by the Deepsea Metro I (UDW drillship) which is currently drilling the Mzia-2 appraisal well. Upon completion of the Mzia appraisal, the rig will return to Jodari to perform a drill stem test and then move on to continue exploratory drilling in Block 1.

Gas Discovery Off Romania
Dec 14, 2012 – Sterling Resources, operator of Block 13 Pelican in the Romanian Black Sea, announced a gas discovery at the Eugenia-1 exploration well. The well was drilled by the GSP Jupiter (300′ ILC) to a measured depth of 7,375 feet. Initial results indicate 72 feet of net gas pay in Late Cretaceous sandstones. Data is still being studied but open-hole logging confirmed the presence of moveable gas. The company is also interested in a 65 foot zone of Eocene limestone which presented gas shows. Attempts to collect pressure data were unsuccessful which is not uncommon in carbonates where matrix porosity is limited. The same Eocene interval turned out to be producible in an adjacent well.
