This course deals with the design, operation, and optimization of onshore gas gathering systems and their associated field facilities, from the wellhead to the central gas processing facility. From a design perspective, the main variables that impact the flexibility and operational characteristics of an onshore gas gathering system will be discussed. Typical operating problems are covered including hydrates, multiphase flow issues, corrosion, declining well deliverability, etc. Exercises will be utilized throughout the course to emphasize the key learning points.
"Instructor was very open to sharing industry experiences and had excellent knowledge of the information. Class discussions on issues others have experienced was helpful for applicability of info." - Process Engineer, United States
"Great course. I liked how it brought reservoir, gas, and plant all together and showed how they interconnect." - Financial Analyst, United States
DR. FRANK E. ASHFORD has over 50 years' experience in oil and gas reservoir engineering, downhole and surface design and operations, as well as oil and gas conditioning and producing facilities. He has been with PetroSkills since 1988 and has worked extensively in most energy producing countries throughout the world. He provides instruction fluently in either English, Spanish, or Portuguese based on material originally prepared in English or Spanish, but presented in the native language requested. He worked with Gulf Research (GR&DC) in Houston, Texas where he developed many reservoir engineering laboratory techniques for the determination of applicable oil/gas/water relative permeability correlations, and choke performance prediction techniques still in application today. Previously, Dr. Ashford was a Professor of Petroleum and Natural Gas Engineering at the Central University of Venezuela in Caracas, where he taught various courses in natural gas engineering technology. He was a founder of the Petroleum Engineering Department in INTEVEP, the research Institute for PDVSA (Venezuela). He was a participant in the initial gas lift optimization operations held in Venezuela, and developed many field, and numerical techniques and correlations for downhole, and surface choke performance with Otis Engineering (US, and Venezuela), and Compania Shell de Venezuela (CSV). He has authored technical articles published in World Oil, JPT, SPE, Intevep Pub., PDVSA, Pacific Oil World, AAPG, SPELAC, and GPA. He holds a BS (1961) and MS (1963) in Petroleum Engineering and a PhD in Engineering Sciences (1970) from the University of Oklahoma. He was one of Dr. John M. Campbell's graduate students from 1962-1968, and participated in the initial data collection and organization for the original John M. Campbell technical textbooks Gas Conditioning and Processing, Volumes I and II. These books provided the basis for a worldwide and extensive training organization initiated by Dr. John M. Campbell during the late1960's, and are still applied by PetroSkills | John M. Campbell for worldwide engineering training to this date.
MR. MARK BOTHAMLEY has experience that covers the areas of design, operation, troubleshooting and optimization of offshore and onshore oil and gas production and treating facilities. Prior to joining PetroSkills he was with BP/Amoco for 24 years, in several locations around the world. Mr. Bothamley is a past chairman of the SPE Facilities Subcommittee and a former member of the GPSA Data Book Editorial Review Board. Mr. Bothamley holds a BS in Chemical Engineering from Lakehead University in Thunder Bay, Ontario, Canada, and a Diploma in Natural Gas and Petroleum Technology from the British Columbia Institute of Technology in Vancouver, BC Canada.
MR. WILLIAM (BILL) DOKIANOS has over 35 years' experience in engineering, production and pipeline. He is a Professional Engineer in the states of Louisiana and New Mexico, and holds a General and Commercial Contractor License in the State of New Mexico. Over the last 7 years he has been instructing for PetroSkills | John M. Campbell. He instructs the PF4 course, 'Oil Production and Processing Facilities'. He has actively consulted over the past 10 years with ExxonMobil, Shell Exploration and Production, Sandridge Energy, Repsol and Chevron. Mr. Dokianos' onshore consulting has focused on optimizing production utilizing casing gas systems, vessel and battery design, revising gun barrel design for better separation, production optimization and production troubleshooting (bad oil and or bad water). His offshore experiences include analyzing and solving poor platform up time at GB 128, GC 65 and other offshore locations. Activities included process control changes due to stacked separator vessels, revising safe charts, operating settings and reconfiguration of pipeline export pumps. He managed a subsea tieback project in which the platform modifications included high pressure vessel redesign, dehydrator expansion, adding a second vapor recovery unit, restaging high pressure and intermediate gas compressors and modifying bulk oil process design. He has been responsible for DOT compliance activities and reporting. This compliance responsibility has included development and implantation of federal risk programs and smart pigging. Mr. Dokianos holds a Bachelor of Science in Electrical Engineering from Wayne State University in Detroit, Michigan.
DR. MAHMOOD MOSHFEGHIAN is a Senior Technical Advisor and Senior Instructor for PetroSkills. He is the author of most Tips of the Month and develops technical software for PetroSkills. He has 40 years' teaching experience in universities as well as for oil and gas industries. Dr. Moshfeghian joined John M. Campbell & Co. in 1990 as a part time consultant and then as full time instructor/consultant in 2005. Dr. Moshfeghian was Professor of Chemical Engineering at Shiraz University. Dr. Moshfeghian is a senior member of AIChE and has published more than 125 technical papers on thermodynamic properties and process engineering. Dr. Moshfeghian has presented invited papers at international conferences. He is a member of the Editorial Board for the International Journal of Oil, Gas, and Coal Technology. He holds a BS (74), an MS (75) and a PhD (78) in Chemical Engineering, all from Oklahoma State University.
