A New Mexico operator saw oil and gas production improve using the patented Vortex DX-I tools at the end of tubing in declining wells. The Vortex tool was set at end of tubing deep in the lateral and close to the formation (typically set at 80 degrees). In each case, oil production was increased and, in one reported case, the oil production increased from 80 barrels of oil per day to over 400 barrels of oil per day for a period well beyond flush production. The 10-day increased production from this one reported well was 3,200 barrels of oil (or $345,000 in production values). PDF
