Toreador reports Akcakoca, other well tests

By OGJ editors
HOUSTON, Dec. 15 -- A group led by Toreador Resources Corp., Dallas, is scheduled to begin testing the Akcakoca-3 well—the 10th successful well drilled in the South Akcakoca subbasin project in the Black Sea off Turkey.

Drilled to a bottomhole location 300 m south of the Akcakoca-1 location and higher on structure, Akcakoa-3 encountered 81 m net gas-bearing sands between 1,146 m and 1,545 m, its TVD, in seven zones in the Eocene Kusuri formation. The top of the Kusuri in the Akcakoca-3 is 500 m deeper than the same producing formations in the 2004 Ayazli-1 discovery well.

Toreador said logs and pressure tests indicate more pay zones than originally prognosticated. The company is expected to complete the well and begin a testing program to further define the reserve potential in the deeper waters of the project area.

Meanwhile, construction of the onshore production center is nearing completion, and testing of major equipment and systems is expected to begin this month. Offshore pipeline construction is slightly behind schedule because of bad weather, but it is scheduled for completion in January.

The Dogu Ayazli tripod has been set, and the Dogu Ayazli-1 and 2 wells are being recompleted. Toreador expects to tie them back in late December after which topsides for the Akkaya and Dogu Ayazli tripods will be installed. The Ayazli tripod is scheduled for installation in February.

Initial production is expected in January as the production center and gathering system are commissioned. The Ayazli platform will be brought on line once installation and well completion activities are complete in first quarter, 2007.

Hungary
In Hungary, Toreador has reentered and completed the KIHA-15 well as a gas producer. During production testing, gas flowed at 1.7 MMcfd, with no associated liquids, through a 1/4 in. choke at slightly over 1,300 psi. Production was from 9 m of perforations at 1,180-89 m in Miocene Badenian carbonates, with net pay estimated at 35 m true vertical thickness. The well's estimated gas reserves are 3.5 bcf.

Operations have begun on the Ot-Ny-5 well reentry, and production testing is scheduled to begin soon. The 1992 well targets Cretaceous-age carbonates that tested 1.6 MMcfd but were never put on production.

Romania
In Romania, preparations are under way to spud the first exploration well in Toreador's Viperesti block. The Naeni-2 Bis will be drilled to about 1,400 m to test the lower compartment of an overturned anticline in Miocene-age Sarmatian sands, and it will continue on to test some deeper Meotian sands.

A second well, the Naeni-6, is scheduled to spud the week of Dec. 18. It will target 2,000 m to test the upper compartment of the Sarmatian overturned anticline as well as deeper horizons. The unrisked potential reserves of the Naeni prospect are estimated at about 6-50 million boe.

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.
