Escopeta's Jackup Arrives in Cook Inlet, Set to Drill

- Escopeta's Jackup Arrives in Cook Inlet, Set to Drill

Spartan Drilling Co.'s Blake 151 jackup rig arrived Aug. 7 in Cook Inlet and cleared U.S. Customs before proceeding to an exploration location in upper Cook Inlet Aug. 10, a spokesman for Escopeta Oil and Gas Co. said.

The rig waited briefly in Kachemak Bay near Homer, Escopeta spokesman Steve Sutherland said in an interview.

"We [held] in Kachemak Bay until we clear customs and finalize some matters with the state Department of Natural Resources. We expect to be moving the rig to the drilling location in the Kitchen Light Unit," Sutherland said.

Escopeta has most of the permits it needs from the state. "Escopeta has an approved plan of operations from Department of Natural Resources," agency spokeswoman Elizebeth Bluemink said. "We plan an informal inspection after they arrive at the drill site but we don't have any pending DNR permits. What's still pending will come from other agencies, the AOGCC (Alaska Oil and Gas Conservation Commission) drilling permit, for example."

"We approved the plan of operations in July. The plan covers drilling related activities and not the transit period to get to the drill site," Bluemink said.

Escopeta is the main leaseholder in the Kitchen Lights Unit and will be operator of the exploration well.

If the rig moves to the location and successfully spuds the well it will qualify for a special state exploration incentive that will pay up to 100 percent of the first $25 million of costs of the first exploration well drilled with a jackup rig in Cook Inlet. Wells drilled by the same rig are eligible for follow-on incentives for the second and third exploration wells, of 90 percent of costs up to $22.5 million on the second well and 80 percent f the first $20 million for the third well.

However, the wells must be drilled for different companies.

The Blake 151 was towed from Vancouver, B.C. To Cook Inlet by three Foss Maritime Co. tugs. The rig was in Vancouver for several weeks undergoing modifications after being moved to the west Canadian city from the U.S. Gulf of Mexico by a Chinese heavy-left vessel.

The rig movement from the gulf was controversial because Escopeta's original plan was to move it directly to Cook Inlet after obtaining a waiver of the U.S. Jones Act from the Department of Homeland Security.

The rig was diverted to Canada after Homeland Security Secretary Janet Napolitano turned down the waiver request. U.S. Shipping interests who work to protect the Jones Act had urged Napolitano to turn down the waiver.

The Jones Act requires shipments of cargo between U.S. Ports to be made with American-built ships. Escoptea hired the Chinese heavy-lift ship because no U.S. Vessels were capable of moving the rig safely around the tip of South America, where there are rough seas, company president Danny Davis said earlier.

U.S. shipping groups are pushing for a penalty to be imposed on Escopta for a Jones Act violation.

"We expect the customs to issue a significant fine once the rig has completed its transit and positioned for duty in Cook Inlet," said Richard Berkowitz, Director of the Transportation Institute, a Seattle-based maritime industry association.

Even with the rig's voyage on a Chinese heavy-lift vessel terminated in Vancouver, B.C., a Jones Act violation has occurred, Berkowitz said.

Meanwhile, a second jackup rig may soon be headed to Cook Inlet. Buccaneer Energy, an Australian company, is purchasing a heavy jackup rig in Asia for drilling in Cook Inlet waters and elsewhere in coastal Alaska. That rig may be moved to Alaska this winter or by early spring.

Semisub Arrives at Finucane South-1 Site

Semisub Arrives at Finucane South-1 Site

Wednesday, May 04, 2011
Tap Oil Limited

Tap Oil Limited on Wednesday provided the following update on the Finucane South-1 exploration well, offshore Carnarvon Basin, Western Australia.

Location/Proposed Depth

The Finucane South-1 well is located in permit WA-191-P, in the northern end of the Carnarvon Basin. The preliminary well location is latitude 19 18` 17.216 S and longitude 116 45` 30.025 E.

Progress

The Stena Clyde semi-submersible drilling rig is on location and the well spudded at 4:15am on Tuesday, 3 May 2011. The well has been drilled to 203m MDRT and the current operation at 0600 hrs Wednesday, 4 May is preparing to run 30" casing.

Forward Plan

After the 30" casing is cemented and blowout preventers (BOPs) installed and tested the well will be drilled to the intermediate 13 3/8" casing depth at approximately 2036m MDRT.

Finucane South-1 is planned to take approximately 20-25 days from spud to reach a final total depth of approximately 3,500m. Upon completion of evaluation the well will be plugged and abandoned in the normal course of offshore operations.

Background

The Finucane South prospect is located at the northern end of the Carnarvon Basin, approximately 15km east of the Mutineer facility. Finucane South-1 will be drilled to identify additional resources to supplement the discovered resources contained in the adjacent Fletcher Field. Tap estimates the Finucane South prospect has a potential gross mean recoverable oil volume of 8 million barrels.

Finucane South is a moderate-sized structural closure mapped at the base of the Cretaceous regional seal. The underlying Late Jurassic Angel Formation primary target will be intersected at approximately 2,960m below sea level. Water depth at the well location is approximately 140m. Finucane South-1 will be drilled 2km SSW of the Finucane-1 well (1978) which intersected oil shows at the top of the Angel Formation despite having been drilled off structure.

Based on Finucane South-1's proximity to other wells in the area (notably Finucane-1 and the Fletcher oil wells) plus its coverage by reprocessed 3D seismic, the risk attached to drilling can be categorised as low-moderate.

WA-191-P Joint Venture Participants
  • Tap (Shelfal) Pty Ltd, 8.2%
  • Santos Limited (Operator), 33.4%
  • Kufpec Australia Pty Ltd, 33.4%
  • Nippon Oil Exploration (Dampier) Pty Ltd, 25.0%
