A deconvolution method for the pressure rate problem for oil and for gas wells
Herein, we demonstrate that, if the source rock is exhumed to shallower depths after peak burial, pore pressure reduction and the associated volumetric expansion of the petroleum – particularly of the gaseous – phase in the pore system will result in the discharge of additional petroleum into the adjacent carrier bed or reservoir formations
New combination plots are then developed for each flow regime to further assist in closure pressure determination.
A recent perforating program performed with guns deployed by wireline and tubing conveyance in two Devonian wells followed an engineered perforation design and provided the best gas flow rates ever measured for this formation even without any further fracture stimulation
