Purchase Gas Well Deliquification – 2nd Edition. Print Book & E-Book. ISBN , He has authored or co-authored: the book “Deliquification of Gas Wells” ( Elesevier), the chapter of the new SPE productions Handbook on Artificial Lift Selection. Deliquification of a low-pressure gas well requires a different approach, tools, and staffing than artificially lifting an oil well.

Rock Mechanics Symposium and 5th U. Sheriff’s Encyclopedic Dictionary of Applied Geophysics, fourth edition. There is a flow regime transition from mist to annular to bubble flow 2. Solution methods include use of surfactants, velocity strings, compression, use of plunger lift, various deliquificatipn pumping methods, gas lift, and the injection of fluids below a packer so gas can flow up the annulus.

There have been numerous papers on implementation and the impact of Compression so it is not the focus of this paper. Advanced search Show deliquifkcation help.

This presentation will illuminate the importance of gas well deliquification technologies for the future. By using this site, you agree to the Terms of Use and Privacy Policy. Rock Mechanics Symposium and 5th U. Possible solutions to this problem include the installation of a velocity string, a capillary string injecting foamers often with corrosive effects on surface wellhead sealsor a pump to continuously or intermittently pump the water to the surface to remove the hydrostatic barrier that the water creates.

Engineers, field technicians, field supervisors, and others who select, design, install, monitor and evaluate, or operate artificial lift systems for use in dewatering gas wells.


A high gas velocity results in a mist flow pattern in which liquids are finely dispersed in the gas.

When natural gas flows to the surface in a deliquificatoon gas well, the gas carries liquids to the surface if the velocity of the gas is high enough.

Views Read Edit View history. This severely affects the gas production and can cause the well to die if corrective action is not taken.

Introduction Liquid loading of as gas well has been described as the inability of the produced gas to remove the Produce Liquids from the wellbore. Telephone 1- Facsimile 1- E-Mail inhouse petroskills. About the course Designed For You will learn Course Content As gas wells deplete, the velocity in the tubing drops and eventually liquids from the well and from condensation begin to accumulate in the tubing.

Of these solutions the most commonly supplied are Compression reduction in surface pressureReduced ID of tubing, and addition of foamers through continuous injection of liquid foam or by surfactant sticks, plunger lift, gas lift, hydraulic jet pump, and rod pump.

A common practice is to use a device called a plunger to lift the liquids.

Due to this, the gas loses the energy to lift the liquid droplets to the dell, and as a result liquids begin to fall down and accumulate in the wellbore, resulting in increased back-pressure on the formation. Shari Dunn-Norman, James Lea. The ultimate recovery of gas is dependent on the economic removal of accumulated liquids, to allow the gas to get produced.

There is a very large list of potential solutions to improve and unload liquid loaded gas wells. From Wikipedia, the free encyclopedia. In smaller strings especially 1. Experiments were carried out on the use of this technology and the results are encouraging.

Under such circumstances, the well is said to be deliquifcation.

The course will consist of slide presentations, example problems, and discussion. Maximize gas production using optimized dewatering techniques Recognize liquid loading in a gas well using field symptoms, critical velocity, and nodal analysis Recognize the advantages and disadvantages of various methods of liquid removal Best install and troubleshoot the various methods Understand economics of each method covered.


In-House Course Presentations All courses are available for in-house presentation to individual organizations. As the gas velocity in the production tubing drops with time, the velocity of the liquids carried by the gas declines even faster. Proceedings of an International Conference Submersible Technology: Log in to your subscription Username. Improved electrical pumps coming onto the market may enhance ga effectiveness of the technology.

Proceedings of an international conference Diverless and Deepwater Techology: The typical result of production below the “critical velocity?? In-house courses may be structured the same as the public versions or tailored to meet your requirements. The basic concept of tubing design is to optimize the tubing in such a manner that it should be large enough in diameter which prevents excessive frictional pressure drop but at the same time, small enough, so that the velocity is high and liquid loading will not occur.

Proper application of artificial lift technology to a loaded up gas well can be one of the wdll profitable ventures that a company undertakes in its overall investment opportunity portfolio. Abstract Many gas wells cease producing economically long before their reservoirs have depleted and artificial lift applications for removing liquids from gas wells around the world are becoming more and more important.

Recognize symptoms of liquid loading in gas wells Critical velocity to analyze wells loading or not Optimize techniques with Nodal Analysis Sizing tubing Compression: He has been an SPE Distinguished Lecturer two times and has presented and organized numerous conferences for artificial lift.
