USA: Telemark, Clipper Results Excite ATP

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.”

Telemark Update

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.

Clipper Update

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. In July 2011, ATP successfully completed and flow tested the first Clipper well, GC 300 #2 ST #1, at a rate of 45.6 MMcf per day and 4,656 Bbls 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.

Telemark

Mirage/Morgus
Phase I of the project focuses on the northern part of the greater Telemark area, which includes the Mirage and Morgus fields.
Located on Mississippi Canyon Block 941 in a water depth of 3,800 feet (1,158 meters), the Mirage field was discovered in 1998 when a well encountered roughly 87 feet (27 meters) of hydrocarbons in two sands. The Morgus field is located on Mississippi Canyon Block 942 in 4,304 feet (1,312 meters) of water, and was discovered when drilling encountered approximately 55 feet (17 meters) of net pay.
In an effort to cut costs, ATP decided to jointly develop these fields due to their close proximity. Combined, Mirage and Morgus hold estimated recoverable reserves of 190 Bcf (5 Bcm).
In 2008, the West Sirius semisub drilled three wells on the Mirage and Morgus fields and reached a total depth of 5,900 feet (1,798 meters) in 3,927 feet (1,197 meters) of water.
To develop the Mirage field, Technip received a contract for the flowlines, risers, jumpers and subsea structures. The contract covered engineering for the installation, welding and installation of two steel catenery risers and two oil and gas export flowlines; fabrication and installation of subsea structures and jumpers and pre-commissioning of the project.
Mirage is operated by ATP, which owns a 25% interest; Statoil owns the remaining 75% interest. Morgus is operated by ATP, but Statoil owns 100% of the interest.
Telemark
Phase II of the project focuses on the Telemark field. Telemark is situated in a water depth of 4,300 feet (1,311 meters) on Atwater Valley Block 63. ATP acquired the field in 2006 and owns 97% interest; BHP Billiton holds 1% interest; Chevron holds 1% interest; and Eni holds the remaining 1% interest.
The field was discovered in 2003 in the southern part of the greater Telemark area when exploratory drilling encountered 140 feet (43 meters) of hydrocarbons in the Miocene sands. The Telemark field was deemed commercially viable shortly after, and ATP began field development preparations.
Situated 7 miles south of the Mirage and Morgus fields, Telemark originally was designed to have its own production hub, a MinDOC II, but the company decided to tie-back the field’s subsea well to the ATP Titan, as well. This development will result in an increase in production rates through ATP Titan in 2010 and 2011.
In May 2009, Bluewater Industries received a contract for the field’s development. The contract covers the design and manufacture of one high-pressure flexible riser measuring 2 miles (3 kilometers) long, and engineering for the installation and welding of one oil and gas production flowline approximately 13 miles (21 kilometers) long. The contact also includes installation of a flowline and associated riser with an option to install an umbilical; fabrication and installation of subsea structures and a jumper; and pre-commissioning of the project.
ATP Titan
In 2007, ATP decided to develop the Telemark area with a floating, drilling and production triple-column spar, the ATP Titan, since accessible infrastructure wasn’t nearby. The MinDOC, a deep draft floating platform, is comprised of three columns linked by pontoons, boasting a higher load capacity and enhanced stability than previous designed semisubmersibles or spars.
In 2007, construction of the ATP Titan MinDOC commenced with construction slated to end in the third quarter of 2009. The facility has a design capacity of 25 Mbopd and 60 MMcf/d (2 MMcm/d) and incoporates six dry tree wellheads with three pairs of future subsea flowlines. Mustang Engineering received a contract to provide detailed engineering and procurement support for the topsides production facilities on the ATP Titan.
Towards the end of 2009, ATP Titan was moored at the Mirage and Morgus fields to complete the drilling of three wells to vertical depths of 14,500 to 17,250 feet (4,420 to 5,258 meters). The vessel will serve as the production platform for the life of the fields’ reserves. Then, ATP Titan will move to the Telemark field to recover its remaining reserves once the vessel has finished producing from the Mirage and Morgus fields.
First production from the Telemark Hub commenced on March 28, 2010, and the vessel has an estimated life span of 40 years.
Future Exploration
A fourth field that is 100% owned and operated by APT — Oasis — is located on Mississippi Canyon Block 943, and may be tied-back to the platform, pending exploration results.
