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.

Gas Well Deliquification – GWD

Due to this, the gas loses the energy to lift the liquid droplets to the surface, and as a result liquids begin to fall down and accumulate in the wellbore, resulting in increased back-pressure on the formation. There are aboutgas wells in the USA and most are liquid loaded. Some films will be shown. 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. He has authored or co-authored: The same concept is also applicable to oil wells when they are at the end stage of production.

Proceedings of an international conference Oceanology: This paper discusses this new technique, results obtained from conducted experiments, and provides advantages to the current methods. Intermediate Instructors who teach this course: The course will consist of slide presentations, example problems, and discussion.

References [ edit ] Gas Well Deliquification: It is the inability of the produced gas to remove the produced liquids from the well bore. G and Dukler A. The rates that these occur at can generally be estimated by the above mentioned research and then displayed by graph Figure 2.

Compression is generally determined on a field wide decision with economics considered for optimizing multiple wells by reducing flowing bottom hole pressure and realizing the increase in production. Proceedings of an international conference Diverless and Deepwater Techology: Shari Dunn-Norman, James Lea As gas wells deplete, the velocity in the tubing drops deliqiification eventually liquids from the well and from condensation begin to accumulate in the tubing.

Views Read Edit View history. The accumulated liquid may be in the form of formation water, condensed water or hydrocarbons condensate which acts as a hindrance to the formation gas getting produced. This increase of liquids in the tubing adds back pressure on the formation, which in turn reduces flow or even stops flow all together.

The ultimate recovery of gas is dependent on the economic removal of accumulated liquids, to allow the gas to get produced. About the course Designed For You will learn Course Content As gas deliquificahion deplete, the velocity in the tubing drops and eventually liquids from the well and from condensation begin to accumulate in the tubing. There is a flow regime transition from wfll to annular to bubble flow 2. As a result of this heating, the fluid density decreases and the gas and vapours flow naturally to the surface.

Plunger lift is an intermittent artificial lift method that uses reservoir energy to produce accumulated liquids, by means of a plunger that operates in a cyclic process with the well alternately flowing and being shut-in. Experiments were carried out on the use of this technology and the results are encouraging.


He has been an SPE Distinguished Lecturer two times and has presented and organized numerous conferences for artificial lift. The entire tubing string has to be of the same size. A common practice is to use a device called a plunger to lift the liquids.

Possible solutions to this problem include the installation of a velocity string, a capillary string injecting foamers often with corrosive effects on surface wellhead deliquificatoonor a pump to continuously or intermittently pump the water to the surface to remove the hydrostatic barrier that the water creates.

At this critical point in time, artificial lift is needed which involves either better use of natural energy available at the bottom hole of wellbore gas lift, plunger lift etc.

It is difficult to swab a small tubing in the event that it gets loaded. Proper application of artificial lift technology to a loaded up gas well can be one of the most profitable ventures that a company undertakes in its overall investment opportunity portfolio.

Under such circumstances, the well is said to be loaded. Production and Completions Engineering Level: Engineers, field technicians, field supervisors, and others deliqujfication select, design, install, monitor and evaluate, or operate artificial lift systems for use in dewatering gas wells.

The production decrease requires solutions in order to fully realize the value of the well.
