Abstract

In this paper, described is the field implementation of a new production method, the water drainage - production system for oilfields with bottom water coning problems. This method enhances the production rate of water-free oil while eliminating hydrocarbon contamination of produced water. The new method was used in a Wilcox sand in North Louisiana to resolve the problem of excessive water cuts experienced in conventional wells. Chemical analysis of water produced in the new method shows minimal contamination with polynuclear aromatic hydrocarbons (PAH), 11 parts per billion. This is an over 50-fold reduction compared to PAH contamination of water produced conventionally. Also, no contamination with oil and grease was measured with a detection limit of 2 mg/l.
