“…However, this is not practical or cost effective and one must collect data judiciously such that well/reservoir performance can be accurately determined 1 . This is an especially important consideration in the deep water environment where the cost of DST's in every well will not be justified and using lower cost MDT, CMR and/or core samples in more wells will have to suffice.…”

These permeability sources include core analysis, nuclear magnetic resonance log (NMR), wireline formation tester, and well testing (DST). However, permeability values from these sources often differ significantly. In many cases, this creates confusion as to which value of permeability should be used to best represent reservoir performance and well productivity.In this paper, permeability values, evaluation methods, scales and applicability of all measurements are discussed and verified with field data.Factors influencing each measurement technique are also discussed.Available permeability data from the various sources in a deep water Gulf of Mexico sandstone reservoir are considered to demonstrate how they may be used to build a model of well/reservoir performance. An accurate knowledge of permeability is critical to forecasting rates. Production facilities may be over-or under-designed if rates are inaccurately predicted, excessive capital expenditure for an over-designed facility or the inability to deliver at high rates for an under-designed facility can cost an operator and its partners dearly.

TX 75083-3836, U.S.A., fax 01-972-952-9435. AbstractPermeability is a critical reservoir parameter that defines well and reservoir performance. An accurate knowledge of permeability is critical to forecasting rates and designing production facilities. The permeability determined from different sources can vary significantly, resulting in inconsistent estimates of well and/or reservoir performance.In this paper, permeability values and evaluation methods, are discussed and verified with field data. It is shown how NMR derived permeabilities calibrated to MDT or comprehensive core data can be used to define well/reservoir performance. By accounting for the effects of overburden, as well as, pore pressure when measuring permeability in core tests, more representative values of permeability can be determined. These values of permeability can be used to accurately calibrate NMR permeability data.The simulation and calibration results are compared to measured well test data. Results from this work show that if these various sources are integrated properly an accurate well productivity model can be achieved.
