Wavefront Technology Solutions Inc. reported that an independent field performance review by Gaffney-Cline and Associates has validated Powerwave results in certain Alberta and Saskatchewan projects.

Gaffney-Cline and Associates was contracted by Wavefront to evaluate the results of Wavefront's Powerwave installations. The study included five fields comprising 58 Powerwave-driven water injector installations having a minimum one-year injection history. The analysis was completed using the Canadian public database, geoScout, which reports an operator's production and injection data. More specifically, the Gaffney-Cline analysis evaluated the production response at surrounding producers that comprised the well patterns supported by water injection utilizing Powerwave pulsing technology.

Increases in estimated ultimate recovery (EUR) were evaluated on a well-by-well and pattern-by-pattern basis. EUR was evaluated with two main methods: log q (oil rate) vs. Q (cumulative oil) and log water-oil ratio vs. Q decline analysis. The decline trend was estimated before and after the Powerwave installations, and the difference in EUR was quantified. The results ranged from 0.7% to 7.4%. The EUR increase is witnessed by either an increase in oil rate, flattening of the oil decline, and a decrease in WOR water-oil ratio.

"Estimated ultimate recovery plays a critical role in driving investment decisions for operators and Powerwave's performance has demonstrated it can increase EUR appreciably," said Wavefront’s president and CEO, Brett Davidson.

"With a 2006 report by Advanced Resources International indicating 400 billion barrels of oil remain stranded throughout the U.S., it's clear that Powerwave can make a important contribution to increased oil recovery in a variety of applications."
