Kinetiko Energy (ASX:KKO) said results from the laboratory tests conducted by Oilfield Technologies Australia from the production test well data concluded that drilling procedures have been the primary cause of the delayed/restricted gas flows observed at the firm's onshore shallow conventional gas opportunities in South Africa, according to a Wednesday Australian bourse filing.
Analyses of actual core samples from recent production test wells confirmed favorable permeability results, and laboratory test results indicated gas permeability reductions of up to 85% created by water and foam invasion.
Several significant adjustments to the drilling process have been recommended and are being incorporated by the firm into its geological modeling, including minimizing filtrate/water invasion.
