Rigless jobs in gas wells

Stabilization of Gas Lifted Wells

Increased production from gas lifted oil wells can be achieved by use of feedback control. Without control the well system may have large oscillations in the flow rate or stabilize itself at a non-optimal production point. These non-optimal production conditions give lower production and/or poor oil/water downstream separation. The study extends the newly introduced approach for controlling gas...

Developing a Novel Temperature Model in Gas Lifted Wells to Enhance the Gas Lift Design

In the continuous gas lift operation, compressed gas is injected into the lower section of tubing through annulus. The produced liquid flow rate is a function of gas injection rate and injection depth. All the equations to determine depth of injection assumes constant density for gas based on an average temperature of surface and bottomhole that decreases the accuracy of gas lift design. Also g...

Installing Plunger Lift Systems In Gas Wells

In mature gas wells, the accumulation of fluids in the well can impede and sometimes halt gas production. Gas flow is maintained by removing accumulated fluids through the use of a beam pump or remedial treatments, such as swabbing, soaping, or venting the well to atmospheric pressure (referred to as “blowing down” the well). Fluid removal operations, particularly well blowdowns, may result in ...

Oil and Gas Wells in Michigan

The integrity of oil and gas wells.

Public concerns about oil and natural gas extraction these days inevitably turn to hydraulic fracturing, where millions of gallons of water, sand, and chemicals are pumped underground at high pressures to crack open rocks. Hydraulic fracturing often occurs a mile or more down, far from the water we drink or the air we breathe. The focus for safety and environmental stewardship should often be s...
