BritNRG reinterpreted the 3D seismic survey shot over Newton post Newton-1 drilling.
Newton-1 well was drilled through oil and water legs of Carboniferous Crawshaw and Longshaw horizons and produced some 50 Mstb of oil before watering out.
The interpretation clearly shows that Newton-1 was drilled through the OWC, downdip of a significant four way dip closure and most of the STOIIP lies updip of the well.
Estimated STOIIP of 2.7 MMStb
- 1.7 MMStb in Crawshaw
- 1.0 MMStb in Longshaw
- Some 0.7MMStb is recoverable with a 25% recovery factor [analogy from BP’s Bothamsall field] though unlike Borhamsall the wells have sufficient deliverability to not require fracking.
- The envisaged development scenario may involve 2 producers, with the existing well as a water injector
