Uruguay’s state-owned petroleum company, ANCAP, has announced that nine oil companies have placed nineteen bids for exploration and production offshore Uruguay.
Uruguay’s second offshore licensing round (Ronda Uruguay II) attracted interest of eleven oil companies but nine of them qualified for the bidding process.
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 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.

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.

ATP Oil & Gas Corporation yesterday announced an operations update:
Drilling operations at the fourth Telemark Hub well at Mississippi Canyon (MC) Block 942 #2 are complete. ATP encountered 167 feet of new net pay sands above pre-drill estimates. These sands are in addition to the 72 feet of logged net oil pay seen in the original target sand. With this additional pay sand, ATP is modifying completion plans for MC 942 #2 and now expects to complete both hydrocarbon sands and establish production in late January 2012. ATP believes that these new pay sands will have a positive effect on production by extending the production life and third-party reserve estimates associated with MC 942.
Operations continue at the second Clipper well at Green Canyon (GC) Block 300 #4, where ATP has encountered oil pay sands. The well encountered 56 feet of logged net oil pay confirming reserves already booked. Completion operations are underway. Production at Clipper is still scheduled to begin in the third quarter of 2012 upon the completion of a pipeline, which is already under contract.
Third quarter production was 24,200 barrels of oil equivalent (BOE) per day, representing an increase of 14.7% over the same period a year ago.
ATP Chairman and CEO T. Paul Bulmahn stated, “ATP is excited with the drilling results from both the fourth Telemark Hub well, where we have encountered additional net pay sands above our projections, and the second Clipper well, which has now reached its total depth with completion operations underway. This development success demonstrates ATP’s commitment to advancing the company’s production growth, cash flow and asset base. ATP expects to begin production from the fourth Telemark well in the beginning of 2012, followed by additional planned production at Clipper and Gomez projects later in 2012, Entrada in 2013/2014 and Cheviot in 2014. We also look forward to drilling our first deepwater well at Shimshon in offshore Israel in 2012.”
ATP encountered 167 feet of additional net pay sands above pre-drill estimates. These sands are in addition to the 72 feet of logged net oil pay seen in the original target sand at the Morgus well located at MC 942 #2
Because of the considerable additional hydrocarbon-bearing sands, ATP is adjusting its completion plan to include two new gravel packs which will extend the projected completion time to late January 2012, and ATP expects a positive effect on production by extending the production life and third-party reserve estimates associated with MC 942.
The MC Block 942 #2 well, located in approximately 4,000 feet of water, was completed at a measured depth of 21,400 feet in the Miocene S sand at ATP’s deepwater Telemark Hub in the Gulf of Mexico. It is the fourth well that will be tied back to the ATP Titan floating drilling and production platform located at MC Block 941. ATP operates the deepwater Telemark Hub with a 100% working interest and owns 100% of the subsidiary that owns the ATP Titan and associated pipelines and infrastructure.
ATP has encountered oil pay sands at the second Clipper well located at GC 300 in the deepwater Gulf of Mexico. The GC 300 #4 well, located in approximately 3,450 feet of water, encountered 56 feet of logged net oil pay confirming reserves previously booked. The 9-5/8 inch casing has been set at 15,778 feet measured depth through the pay intervals. The well will now be completed and tested.
