Investigation of New Tool to Unload Liquids from Gas Wells VortexFlowllc.com Cal Whibbs Premier Production
DEMAND FOR NATURAL GAS Rise in demand due to, Low cost per unit of energy Cleaner burning properties Increased useage, Residential heating Automobile usage Power generation plants
GAS PRODUCTION Production accompanied by, Water / brine Condensate Resulting in, Back-pressure on formation Reducing gas deliverability
LIQUID UNLOADING Conventional unloading methods Soap sticks Plungers Rod pumps Swabbing These methods require additional capital and operating expenditures.
CHANGING THE FLOW MECHANISM Mingaleeva in his paper “On the Mechanism of a Helical Motion of Fluids in Regions of Sharp Path Bending” determined that, Mingaleeva in his paper “On the Mechanism of a Helical Motion of Fluids in Regions of Sharp Path Bending” determined that, “ The path of least resistance for liquid and gases is determined to be of a helical trajectory, and that the slope of the helix varies within 45-65 o from the horizontal. The helical path was more favorable from an energy utilization viewpoint, as the power spent to overcome the hydraulic drag for raising an air column, as compared to the motion and rising of equivalent air mass at the same velocities by a straight column is significantly lower.”
FLOW MODIFYING TOOLS Technology used in the coal and potash industries for almost a decade. In 2001 VortexFlow, LLC acquired rights to use this technology in the Oil and Gas Industry. Installed over 200 surface units. Contributed to 5% - 40% increase in gas production. Consistently shifting decline curves when compared to wells’ prior experience.
CONCLUSIONS VX tools sucessfully reduces liquid loading, VX tools sucessfully reduces liquid loading, Consistent results at varying pressures The tool lowered critical velocity Testing program allowed improvements in tool design to be evaluated. Testing program allowed improvements in tool design to be evaluated. Potential use in, Potential use in, Avoiding liquid-loading in flowing wells Replacing marginal pump jacks Replacing plunger systems Improving flow in horizontal wells Reducing power consumption of ESPs Being A slug stabilizer by reducing slug sizes Reducing gas requirements in artificial gas lift
