Auteur: John W. Ely

Mr. Ely started his career with Halliburton Co., in 1965, working as a technician for the Analytical group while completing his college work. He graduated from Oklahoma State University in 1968 with a Batcheler’s in chemistry. On returning to Halliburton, Mr. Ely served as chemist and senior chemist in fracturing research before transferring to International Operations in 1973. While in fracturing research, he was instrumental in the development of the first high temperature fracturing fluids. He also developed nonaqueous energized systems. In 1973 he transferred to his first assignment overseas was in south Iran as a district engineer. In 1975, he was promoted to technical adviser, Eastern Hemisphere, and transferred to Bahrain. He traveled and worked in eleven Mideast countries in this position. In 1976, John transferred to Dubai, U.A.E. The following year, he was promoted to technical adviser, International Operations, and was based in Duncan, Oklahoma where his primary duty was to coordinate all phases of research with international field operations. Ely joined Nowsco Services in 1980 as Engineering Manager. His responsibilities included overseeing chemical and mechanical research and coordinating training for field engineers. In 1985, John joined S.A. Holditch and Associates as Vice-President of Stimulation Technology. In addition to designing and supervising hundreds of stimulation treatments, he was involved in research on fracturing fluids under the auspices of the Gas Research Institute. Additionally, he served as an expert witness in areas involving completion and stimulation of oil and gas wells. In May 1991, John founded Ely & Associates Corp. This company provides a blend of practical and technical expertise on well completion, stimulation fluids and equipment, and reservoir analysis. John holds several patents and has numerous publications, including the first and second edition of books titled “Stimulation Treatment Handbook/ An Engineer’s Guide to Quality Control”. He is also a contributing author to the 1989 and 2020 issue of the S.P.E. monograph on hydraulic fracturing (Recent Advances in Hydraulic Fracturing), writing chapters on hydraulic fracturing fluids. He has also published a chapter in the “Modern Fracturing” publication by BJ Services. Mr. Ely typically teaches hydraulic fracturing 3-5 times a year. Ely and Associates has become known as the premier fracture design and oversight organization in the industry. Particularly in the last 20 years, John has become recognized as the leading expert in the design and implementation of the water fracs. Ely has designed literally thousands of water fracs using technology learned while exploiting both source rock reservoirs and tight conventional rock. His “Waterfrac Sweep” process has been successful in shale, tight sands, and fractured carbonates. Mr. Ely is a member of the American Chemical Society, The Society of Petroleum Engineers, and is a fellow of the American Institute of Chemistry. He was the recipient of the prestigious John Franklin Carll award for excellence in petroleum engineering for 2020. In 2021, he was awarded the Legend of Hydraulic Fracturing award at the SPE Hydraulic Fracturing Conference.
