Background to Andrews-1-17 Well and the West Bowlegs Prospect

The target for this well is the Hunton Limestone, one of the main hydrocarbon reservoirs in Oklahoma.  The Hunton Limestone is unconformably overlain by the main oil-prone source rock, the Woodford Shale and is in an excellent position for the migration of oil. 

Primary oil recovery is expected to be by solution gas drive with any gas recovered to surface being sold into the local network.   

Reach is an accredited operator in the USA, owning and operating oil and gas production facilities in Seminole and Pottawatomie Counties in Oklahoma. All prospects are generated by Reach which owns modern seismic equipment, supplied by a UK based company Stryde Limited.
