Nine Oil Firms Table Bids for Ronda Uruguay II

Uruguay’s state-owned petroleum company, ANCAP, has announced that nine oil companies have placed nineteen bids for exploration and production offshore Uruguay.

Bids come from oil majors for the 15 blocks offered by the Uruguayan government for the oil exploration and production in the Oriental del Plata, Pelotas and Punta del Este offshore basins.

Uruguay’s second offshore licensing round (Ronda Uruguay II) attracted interest of eleven oil companies but nine of them qualified for the bidding process.

UK’s BP and the BG Group, France-based Total, Dutch Shell, Tullow Oil Plc and Exxon Mobil Corp. all filed the bids. Furthermore Spain’s Cepsa, Murphy Oil and Argentina’s YPF were among the bidders.

The marine platform is already explored by a consortium of Petrobras, YPF and Galp, that were the bidding winners in the first Uruguay Round in 2009. According to ANCAP authorities there is a big increase in the oil sector interest on the Uruguayan offshore, when compared with the first bid where only six oil companies asked for qualification.

ANCAP is expected to come up with the results of the bidding later during the day.

Murphy Oil Malaysia Completes Rigless Intervention Campaign Using Welltec Services

Murphy Oil Malaysia recently completed a highly successful, rigless intervention campaign using Welltec services. Not only did the operation allow immediate production from a “lost” well, but it also saved the time and cost of a rig based sidetrack. The end result is expected to add 20 MMscf/d into the production portfolio.

In the first well, the drift run hung up at 945 ft MD when trying to perforate the well. Based on previous experience, the cause was suspected to be part of a cement wiper plug. This was pushed down to a nipple profile at 4,314 ft MD, leaving it still 1,690 ft above the perforation depth. After only minutes of milling, the Well Miller made it through the plug, which allowed the Well Tractor® to push it down to 6,398 ft MD, approximately 380 ft below the target perforation interval. Thereafter the well was perforated and put on production.

In the second well, a poor cement job had made the primary target zone inaccessible and left an obstruction inside the tubing. With pressing rig commitments there was insufficient time to fix the problem, leaving the well temporarily abandoned and a candidate for future sidetracking. Based on the success of the first well, the Well Tractor and Well Miller were used to push the obstruction from 400 ft to 2,132 ft MD , meeting the objective to prepare the well for sidetracking.

However, it was decided to attempt to push the obstruction as far as possible. Using the Well Tractor and Well Miller the well was cleared well beyond the sidetrack target depth to an eventual Hold Up Depth of 8,743 ft MD. Getting this far down the production string allowed access to two of the three reservoirs in this well, which could now be completed for production rather than scheduled for a sidetrack workover.

USA: ATP Successful with Second Clipper Well Testing

image

ATP Oil & Gas Corporation  today announced the successful completion and testing of the second Clipper well at rates of 9,000 Bbls per day and 4.6 MMcf per day.

When combined with the first Clipper well this brings the total test rates to approximately 13.7 MBbls of oil per day and 50.2 MMcf of natural gas per day or 22 MBbls equivalent per day (62% oil).

The second Clipper well is the #4 well located at Green Canyon 300 (GC 300) in the deepwater Gulf of Mexico. The #4 well, located in approximately 3,450 feet of water, logged approximately 56 feet of net oil pay confirming reserves previously booked. The 9-5/8 inch casing was set at 15,778 feet measured depth through the pay intervals. In July 2011, ATP successfully completed and flow tested the first Clipper well, GC 300 #2 ST #1, at a rate of 4,656 Bbls per day and 45.6 MMcf per day.

The pipeline lay barge for the Clipper wells is contracted for third quarter 2012 and will tie in both the GC 300 #4 and #2 wells to the Murphy Oil-operated Front Runner production facility. ATP operates Clipper and presently owns a 100% working interest.
