A reprint of Formation Water Resistivities originally compiled by Don Cardinal (1984) is now available on the EORI website. This publication is a valuable resource for establishing Rw values necessary for calculating oil and water saturations from wireline logs.

A reprint of Formation Water Resistivities originally compiled by Don Cardinal (1984) is now available on the EORI website. This publication is a valuable resource for establishing Rw values necessary for calculating oil and water saturations from wireline logs. Data are compiled by basin and include: well name and location, formation, depth, source of the water, Shut-in-Pressure, and measured water resistivity.

When it comes to electrifying the oilfield, the industry narrows its focus onto monthly energy charges (energy, demand, and basic charges), somewhat disregarding the considerable capital expenditures necessary to build out and maintain electric infrastructure. Onsite generation may not be the optimal solution in every application, but at least in terms of cost in the current environment, generators appear to offer a competitive alternative.
