Discipline: Production and Completions Engineering
Duration: 5 days
Instructor(s): Shari Dunn-Norman, James Lea
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. 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 course introduces this problem and discusses how to recognize liquid loading as opposed to other possible well problems. The course will then cover the various methods of solving the problem of liquid loading, showing how to apply the various solutions and the advantages and disadvantages of each method. Solution methods include use of surfactants, velocity strings, compression, use of plunger lift, various other pumping methods, gas lift, and the injection of fluids below a packer so gas can flow up the annulus.
Participants will learn to recognize the problems and symptoms of liquid loading and determine which methods can solve the problem and select the optimum method/s after attending the course. There are about 400,000 gas wells in the USA and most are liquid loaded. Solving this problem may on the average increase production by ~40% per well. The course will consist of slide presentations, example problems, and discussion. Some films will be shown. Effects of deviated or horizontal well applications on all methods are discussed. Special considerations for the use of each system in unconventional or horizontal wells are also discussed. One personal computer is provided, at additional cost, for each two participants.
"Good to get a general overview of different lift methods available." - Production Engineer, United States
"Liked plunger lift the most. Because I am treating tight gas/oil wells and there are a lot of workover jobs especially plunger lift." - Reservoir Engineer, South Korea
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.
You Will Learn:
DR. SHARI DUNN-NORMAN is a professor of Petroleum Engineering at Missouri University of Science and Technology with 35 years of industry and academic experience. She worked for Atlantic Richfield (ARCO) in domestic and international production operations, where she designed gas lift, reciprocating rod and electrical pump installations, in addition to well completions and workovers. She has taught artificial lift, production engineering and well completions for more than 20 years and has conducted a wide range of research in pipeline well flow, well construction for the protection of USDW's, hydraulic fracturing and well completions. She has co-authored and edited the book, "Petroleum Well Construction", and a number of papers related to well completions. Shari holds a BS degree in Petroleum Engineering from the University of Tulsa, and a PhD in Petroleum Engineering from Heriot-Watt University, Edinburgh, Scotland.
DR. JAMES F. LEA, JR. is an instructor of industry courses and is involved in industry production and artificial lift related projects. He has received the SPE award for 'Legends of Artificial Lift.' He spent 20 years with Amoco Corporation and was involved in consulting on flowing/lifting wells, testing, and research on lift methods, creating new computer programs for lifted and flowing wells, teaching production schools and monitoring JIPs on pipeline flow, artificial lift, erosion, corrosion, and others. He is on the API and SPE committees for electrical submersible pumps, gas lift, and artificial lift systems, and is a member of the panel for the ESP roundtable. He has been an SPE Distinguished Lecturer two times and has presented and organized numerous conferences for artificial lift. He played a major role in organizing the Denver Gas Well De-Watering forum, which is continuing after multiple successful occurrences. 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 and other book chapters, as well as over 65 technical papers and articles on artificial lift systems. He received the SPE Production Engineering Award in 1996 and was the recipient of the 1990 J. C. Slonneger Award from SWPSC, Lubbock, Texas, given to individuals who have made outstanding contributions in the field of petroleum engineering. He is a Registered PE in Texas, has 9 US patents, and received a BSME and MSME in Mechanical Engineering from the University of Arkansas and a PhD from Southern Methodist University.
