More details about the topic

Petroleum industry experts estimate 70% Russian reserves are hard-to-recover. Significant reserves are in low permeable reservoirs. In this situation commingled production is a way to make production economically profitable. It increase life time of the field, several times decrease CAPEX and 1.5 times decrease OPEX.

Author present method of individual evaluation of commingled reservoirs. Reservoirs formation pressures, improbabilities and skin-factors are determined by production logging (PL) methods and well-tests.

“Eclipse” and “tNavigator” 3D numerical simulation approved Dupui equation for commingled production for pseudo steady times for homogeneous fluid.

Traditional well-tests interpretation average properties of commingled formations are determined. PL gives formation rates. But this information itself isn’t enough for individual formation properties estimation. For that additional information is required. It can be formation skin-factor difference (ΔS=S1-S2) from frac design or formation permeability ratio(alpha=k1/k2) from open hole logging.

Such method implemented on several Western Siberia oil fields, reliable information is obtained. It was used not only for long term formation development planes (FDP) but for quickly implemented production enhancement operations, like re-fracturing, injection optimization, etc. method implementation on one of Meddle East fields results in FDP changes and additional well drilling.
