Kazakhstan
Tethys Petroleum Ltd. reported a flow of more than 4,300 b/d of oil from a Cretaceous sandstone at the AKD06 Doris appraisal well in the North Ustyurt basin in Kazakhstan.
The company gauged the well on a 66⁄64-in. choke at a rate of 4,304 b/d of 45° gravity oil with 186 psi flowing tubing head pressure from an interval at 2,165-70 m. Flow was restricted for safety reasons, and data indicate an absolute open flow potential in excess of 6,000 b/d. The well is tied into test production facilities.
Malta
Mediterranean Oil & Gas PLC, through subsidiaries, has let a contract to Fugro-Geoteam Pty. Ltd. to shoot 1,000 sq km of long-offset 3D seismic in Area 4 in the Mediterranean off Malta. Acquisition is expected to take about 30 days. Processing is to start as soon as acquisition is complete, and results are to be in hand by the end of first-quarter 2012. MOG holds blocks 4, 5, 6, and 7 in Area 4 totaling 5,700 sq km bordering Libya.
Area 4 is covered by various vintages of 2D seismic data and by a 3D survey over the western part of Block 7. Since 2007, MOG has shot 1,012 sq km of 2D seismic and has reprocessed in time and depth the existing 3D dataset. MOG reinterpreted the entire 2D and 3D package available in the PSC, confirming four prospects and five leads.
The three most mature prospects are in Block 7, along the ramp setting of the Melita-Medina graben, close to the Libya Pelagic basin (see map, OGJ Feb. 13, 2006, p. 37).
MOG, through its Malta Oil Pty. Ltd. and Phoenicia Energy Ltd. subsidiaries, holds a 90% operated working in the Malta PSC. Leni Gas & Oil Investments Ltd. has 10%.
Oman
A group led by CC Energy Development SAL averaged 6,989 b/d of oil in October from the early production system on Blocks 3 and 4 onshore Oman.
Long-term production tests have been carried out on wells in Saiwan East field on Block 4 and Farha South field on Block 3. Production is up, said Tethys Oil AB, which has a 30% interest in the blocks, and rates continue to vary depending on test program design and available capacity.
CC Energy Development Oman branch is operator with 50% interest, while Mitsui E&P Middle East BV has 20%.
Poland
Talisman Energy Inc., Calgary, has completed drilling a shale gas exploratory well in the Baltic basin in Poland.
The Lewino 1G-2 well, on the Gdansk W concession, went to 3,600 m and encountered continuous gas shows over more than 1,000 m in middle and lower Silurian shales, Ordovician, and upper Cambrian, said partner San Leon Energy PLC (OGJ, Nov. 7, 2011, p. 36). Gas shows consist of methane with small percentages of ethane, propane, butane, and pentane.
More than 310 m of core were taken in the well to evaluate the rock properties, and an extensive open hole logging program was also performed to further evaluate the potential of the area. Evaluation and interpretation of the core and logs is expected to take 3-4 months in preparation for continued operations later in 2012.
Following completion of the well for potential future operations, Talisman will move the rig to the Braniewo concession to spud the Rogity-1 well, to be followed by a well on the Szczawno concession. Future operations are expected to include a long-offset horizontal and multistage frac.
The next step, San Leon Energy said, is to evaluate the geological data in preparation for the next phase: to prove the viability of commercially producing the huge quantity of gas from the Baltic basin.
