The gas potential of the Marcellus Shale of the Appalachian Basin has made it an attractive investment opportunity. Horizontal wells and hydraulic fracturing have boosted production rates and recoverable reserves…

A new approach makes fast, accurate reservoir modelling a practical component of field management. Drilling rates are at an unprecedented level, generating large volumes of data that, if modelled, could…

Complex and unconventional reservoirs provide important reserves to the world’s energy supply however, they are often challenging to produce. Systematic petrographic studies take a close look at these reservoirs yielding…

Can the reported reserves figures of OPEC countries be trusted? And if not, what are the implications of this to government policy and decision making? “A few years ago, in…

Between 1995 and 2003, reserve growth from existing fields worldwide added three times more oil to conventional reserves than new field discoveries. Estimation of future reserve growth will be a…

High-resolution, while-drilling electrical imaging provides a 360 degree map of the borehole wall in its most pristine state, before significant mud invasion and bore- hole degradation. This real-time information provides…
