Dec 13, 2012 – Norwegian oil major Statoil announced Thursday that it plans to use seismic cables on the seabed to help produce 30 million additional barrels of oil from its Snorre and Grane fields. The company has signed contracts worth $160 million with U.S. firm Geospace Technologies to deliver the cables, which will be part of a permanent reservoir monitoring (PRM) program. Statoil believes the technology will allow it to better understand the reservoirs because they are stable and able to provide a more accurate picture of the subsurface than cables that are towed on the surface and which are subjected to wind, waves and currents. Statoil plans to lay more than 400 miles of seismic cables. Statoil currently recovers around 50 percent of the oil from its operated fields on the Norwegian continental shelf.

Mzia-1 is BG Group’s first discovery within the deeper Cretaceous section and opens an extensive new play fairway within the Group’s offshore acreage in Blocks 1, 3 and 4, to complement the now proven Tertiary fairway.
Preliminary evaluation of the results indicates 55 metres of natural gas pay in good quality sands. An extensive logging programme has been completed, including the acquisition of pressure data and gas samples.
Significantly, the well has de-risked a number of adjacent Cretaceous prospects, which could form part of a future Mzia hub. These prospects are expected to be tested in a future appraisal programme to be defined following incorporation of data from this new well and 3D seismic.
The new resources proven by Mzia and the potential of adjacent prospects are currently under evaluation. Prior to drilling Mzia-1, BG Group had estimated mean total gross recoverable resources approaching 7 trillion cubic feet of gas from the four previous discoveries drilled in Tanzania.
Mzia-1 is approximately 45 kilometres offshore southern Tanzania in a water depth of 1 639 metres. It is some 23 kilometres from the Jodari-1 discovery and is part of the 2012 three-to-four well exploration programme.
Following the imminent completion of operations at Mzia, the Deepsea Metro-1 will relocate to Block 3 for the drilling of the next exploration prospect, Papa-1.
BG Group as operator has a 60% interest in Blocks 1, 3 and 4 offshore Tanzania, with Ophir Energy plc holding 40%.
