Gas And Oil Reservoirs News

Eidesvik has ordered two large, state-of-the-art seismic vessels of the type Ulstein SX120 from Ulstein Verft. The ships will be delivered in spring 2010. The contract’s total value is about $223.3m. Eidesvik is known for innovation and a green profile. The ships that Eidesvik has ordered will be contracted by the world’s largest seismic company, the merged CGG-Veritas. “The ships are gentle on both the external environment and the working environment onboard. We believe the Ulstein X-Bow’s smooth and gentle motion in heavy sea makes it highly suitable for seismic operations,” says Meling. “The bow also helps reduce fuel consumption, which means less pollution. In oceanic seismic surveys, the sea bottom is examined with shock waves in the search for gas or oil reservoirs.

Santos Limited (STO) announced that it has completed testing of the Dua-5X well, offshore Vietnam, after discovering multiple gas and oil reservoirs in the southern fault block of the Dua structure. The company reported that the two reservoir intervals have been tested with the primary reservoir target flowing oil at a stable rate of 5,543 barrels of oil per day (bopd) plus 6.76 million standard cubic feet of gas per day through a 2 inch choke. The oil and gas producer said that a deeper secondary reservoir flowed at a rate of 247 bopd through a 28/64” choke. Santos reported that work would now commence on the resource assessment and preparation of a reservoir evaluation report, which is the first step in the commercialization process within the PSC terms.

According to reports, the Australian oil exploration company Santos announced an oil and gas discovery at the Dua-4X exploration well currently being drilled in exploration Block 12E, offshore of Vietnam. Initial tests at the Dua-4X and Dua-4X ST1 wells, operated by Premier Oil, discovered oil and another well is to be drilled to evaluate reserves in the southern part of the field, said a Santos report. Santos have agreed in April this year to take a 37.5% interest in two Vietnam exploration permits - Block 12E and Block 12W. Dua-4X was drilled down-flank from the 1974 Dua-IX disco very well that produces: 1,500 barrels of oil per day. Following the intersection of hydrocarbons in the Dua 4X,vprineal well, a sidetrack has been drilled (Dua-4X ST1) to provide further geological information.
