Woodside JV turns up more hydrocarbons off Mauritania

By OGJ editors

HOUSTON, Dec. 2 - A group led by Woodside Mauritania Pty. Ltd. appears to have another discovery on the West African margin off Mauritania.

Wireline logs indicated a 49.5-m gross gas column overlying a 38.5-m gross oil column at the Chinguetti 4-6 exploration well on the Tiof prospect on Mauritania Area B, Block 4.

Woodwide drilled the well to 2,870 m in 1,080 m of water 90 km west of Nouakchott and 25 km north of the Chinguetti oil discovery, said Roc Oil Co. Ltd., Sydney, which has a 2.4% interest in the Area B production sharing contract.

"The hydrocarbon bearing zone overlies a gross 73-m interval containing poor quality sands in which it has not been possible to demonstrate the presence of oil," Roc Oil said. "Water bearing sandstones have been confirmed below the 73-m interval."

More drilling is needed to determine the extent of the hydrocarbon-bearing column, Roc Oil said.

Other Area B interest holders are Woodside and AGIP Mauritania BV 35% each, Hardman Resources Ltd. 21.6%, and Fusion Mauritania B Ltd. 6%.

Meanwhile, Woodside spudded the Chinguetti 5-1 (Poune) exploration well on Dec. 1 in 926 m of water in Block 5 of Area B 48 km north of Chinguetti and 27 km northeast of Tiof.

Woodside, as drilling manager, spudded an exploration well projected to 3,800 m or Paleocene sands on the Pelican prospect on Block 7. Drill site for the rank wildcat is in 1,679 m of water 150 km north of Chinguetti. Paleocene sands have not been targeted previously in the region.

The Block 7 group includes Dana Petroleum E&P Ltd., operator, 80%, Hardman 18%, and Roc Oil 2% plus a 3.5% option.

Global LNG: Adjusting to New Realities

Fri, Mar 20, 2015

Oil & Gas Journal’s March 20, 2015, webcast will look at how global LNG trade will be affected over the next 12-24 months by falling crude oil prices and changing patterns and pressures of demand. Will US LNG production play a role in balancing markets? Or will it add to a growing global oversupply of LNG for markets remote from easier natural gas supply? Will new buyers with marginal credit, smaller requirements, or great need for flexibility begin to look attractive to suppliers? How will high-cost, mega-projects in Australia respond to new construction cost trends?

US Midstream at a Crossroads

Fri, Mar 6, 2015

Oil & Gas Journal’s Mar. 6, 2015, webcast will focus on US midstream companies at an inflection point in their development in response to more than 6 years shale oil and gas production growth. Major infrastructure—gas plants, gathering systems, and takeaway pipelines—have been built. Major fractionation hubs have expanded. Given the radically changed pricing environment since mid-2014, where do processors go from here? What is the fate of large projects caught in mid-development? How to producers and processors cooperate to ensure a sustainable and profitable future? This event will serve to set the discussion table for the annual GPA Convention in San Antonio, Apr. 13-16, 2015.

This event is sponsored by Leidos Engineering.

The Future of US Refining

Fri, Feb 6, 2015

Oil & Gas Journal’s Feb. 6, 2015, webcast will focus on the future of US refining as various forces this year conspire to pull the industry in different directions. Lower oil prices generally reduce feedstock costs, but they have also lowered refiners’ returns, as 2015 begins with refined products priced at lows not seen in years. If lower per-barrel crude prices dampen production of lighter crudes among shale plays, what will happen to refiners’ plans to export more barrels of lighter crudes? And as always, refiners will be affected by government regulations, particularly those that suppress demand, increase costs, or limit access to markets or supply.
