Parkmead considers stimulation for twin-field North Sea oil project

ABERDEEN, UKParkmead has commissioned AGR Tracs International to conduct a reservoir study concerning well stimulation for the Greater Perth Area (GPA) field development in the UK central North Sea.

Fracture stimulation could increase oil flow rates and oil reserves recovery from thePerth and Dolphin fields, Parkmead believes.

The company has discussed a tieback of the GPA production to the Nexen-operated Scott complex.

Perth has in-place oil volumes of 197 MMbbl for the core part of the field, and 498 MMbbl when the northern areas are included. The reservoir has a gross oil column of around 2,000 ft (610 m), making it ideal for fracture stimulation, Parkmead claims.

Both fields are in the Moray Firth area, close to large producing oil fields such as Piper, Claymore and Tartan, and are Upper Jurassic Claymore sandstone accumulations that have tested 32-38° API oil at production rates of up to 6,000 boe/d per well.

At Perth, the sandstone forms a combined structural-stratigraphic trap, onlapping the Tartan Ridge to the north, with a southward-thickening and dipping sandstone wedge.

The sandstones that comprise the accumulation were deposited as deepwater turbidites sourced from the Halibut Horst, with a minor contribution from the Tartan Ridge.
