Gulf of Mexico: Stone Energy Completes Taggart Prospect Drilling Ops

Stone Energy Corporation provided an update on the deep water Taggart prospect, including the exploratory well drilled at Mississippi Canyon 816. Drilling operations have been completed and the rig is being released.

The well has been logged, and pressure readings, cores and fluid samples have been taken in the Pliocene and Upper Miocene section sands. The data indicates a discovery with approximately 90 feet of net oil and gas condensate pay in two sands. The partners plan to further analyze the data from this well and develop a plan which is expected to include a sub-sea tie back to an existing facility. Stone holds approximately 23% working interest in the project, and LLOG Exploration Offshore, L.L.C. is the operator.

A discovery was also made on the Taildancer prospect at Ship Shoal 113, with the well encountering 130 feet of net oil and gas pay. Production from this discovery is projected to be on line in the fourth quarter of 2013. Stone is the operator with a 100% working interest.

The rig for the deep water San Marcos prospect at Mississippi Canyon 983 is on location and has begun drilling. Stone holds a 25% working interest in the prospect which is operated by Apache Deepwater LLC.

Stone also provided updated production guidance for the third quarter of 2013, increasing from 42-45 Mboe per day (252-270 MMcfe per day) to 46-49 Mboe per day (276-294 MMcfe per day). The full year guidance has also been increased from 41-44 Mboe per day (246-264 MMcfe per day) to 43.5-45.0 Mboe per day (261-270 MMcfe per day). The increase was due to higher projected Appalachian volumes, incremental volumes from the La Cantera field and a more active workover/recompletion GOM shelf program. The guidance still incorporates some projected hurricane shut-in time as well as reduced fourth quarter volumes in Appalachia due to cold weather pipeline restrictions.

Additionally, Stone’s Board of Directors has authorized an increase to the 2013 capital expenditure budget from $650 million to $710 million, which excludes major acquisitions and capitalized SG&A and interest. Most of the capital expenditure budget increase is expected to be in the GOM deep water, with a minor increase in the Appalachia area. The final capital expenditure amount and the allocation of capital across the various areas is subject to change based on several factors including permitting times, rig availability, non-operator decisions, farm-in opportunities and commodity pricing.

Pryderi Partners Granted Permit Extension

Jul 11, 2013 – IPB Petroleum and CalEnergy were granted a 12-month suspension and extension to years 2 and 3 regarding the work program for permit WA-424-P off Western Australia. A tight rig market prompted the joint venture partners to seek the extension in order to have more time to source a suitable rig to drill an exploration well on the Pryderi prospect. The extra time also allows for the submission of needed revisions to the Pryderi Environmental Plan and Oil Spill Contingency Plan. Submission of the revisions is expected to take place mid-July 2013. Assuming the revisions are accepted and all regulatory approvals are granted, IPB expects to be ready to spud Pyderi-1 in 4Q 2013.

Gulf of Mexico: Shell Announces Successful Exploratory Well at Vicksburg Discovery

Shell announces a successful exploratory well at Vicksburg in the deepwater Gulf of Mexico. The well is located 75 miles (120 kilometers) offshore in the De Soto Canyon Block 393 in 7,446 feet (2,269 meters) of water. It was drilled to a total depth of 26,385 feet (8,042 meters) and encountered more than 500 feet (152 meters) of net oil pay.

In total, the Vicksburg “A” discovery is estimated to hold potentially recoverable resources of more than 100 million barrels of oil equivalent (mmboe). It adds to the more than 500 mmboe of potentially recoverable resources that have already been discovered and appraised at the nearby Appomattox discovery. Vicksburg “A” is a separate accumulation from both Appomattox and the 2007 Vicksburg “B” discovery.

“The results of the Vicksburg well strengthen our existing deepwater Gulf of Mexico exploration portfolio and should contribute to the nearby Appomattox discovery,” said Mark Shuster, Executive Vice President Shell Upstream Americas Exploration.

Shell (the operator with a 75% interest) and Nexen, a wholly-owned subsidiary of CNOOC Limited, (25% interest), are following up the Vicksburg “A” well with a sidetrack well to test the Corinth prospect, a separate fault block from the Vicksburg discovery. Further exploration drilling targeting tie-backs to Appomattox will follow.
