Carl Johnson has over thirty years of broad experience in the oil & gas industry in all aspects of engineering & operations. With VIKING he is currently focused on HPHT well design including tubular design, corrosive environment assessment, annular pressure buildup analysis and mitigation and procurement solutions. He has assisted numerous operators in the preparation of training and design documents.

After earning his Petroleum Engineering degree from Marietta College in Ohio, Carl worked for both major and independent operators. Prior to founding VIKING Engineering, he spent fifteen years with Sonat Exploration Co., where he directed drilling programs throughout the U.S. and managed both business unit and corporate engineering and corporate procurement efforts. He has worked extensively in most major U.S. oil basins, including the harsher environments of the Gulf of Mexico and South Texas.

In 2001, Carl co-founded VIKING Engineering, L.C. with Bob Moe. Carl has co-authored several corporate design manuals and articles for publications.

G. R. "Bob" Moe, P.E.
Co-Founder/Partner

For most of his career, Bob Moe has been in pivotal major project planning, scheduling, and coordinating assignments with major operators. His seventeen years of experience with a major petroleum producer includes quality assurance expertise in the manufacture of equipment for high pressure and sour gas production, drilling and subsurface operations. Bob's current work encompasses training and HPHT casing design, connections, and material selection for deep, high pressure, sour wells.

Bob earned his Bachelor's degree in Civil Engineering from South Dakota School of Mines and Technology in 1975. He spent seventeen years with Exxon Company, USA, where he led the Mobile Bay Completions Technology Quality Assurance Team. Bob left Exxon to join Oil Technology Services as Vice President - Engineering. While with OTS, Bob managed the drilling, completions, and production of technically complex wells. Bob co-founded VIKING Engineering, L.C. in 2001.

Bob has authored several design manuals and technical articles for industry publications. He is a registered professional engineer.

Richard A. Miller, P.E.
Consultant

Rich Miller, with eleven years of oilfield consulting experience, is currently focused on deepwater casing programs for high profile projects and annular pressure buildup. His work with a large oilfield consulting firm required stress analysis for critical wells worldwide. He also has a familiarity with financial and quantitative analysis.

Rich attended Rice University, where he earned a Bachelor's of Science, a Master's degree in Mechanical Engineering and a MBA. Recently, Rich co-authored the BP Advanced Well Design Assurance manual. He was, also, part of a six person team that was awarded the 2002 BP Helios Innovation Award for pioneering work in Deepwater/Subsea Well Design Integrity Development.

Peter Erpelding, P.E.
Consultant

Peter Erpelding specializes in mechanical and thermal analysis of drilling and completion equipment and operations. He handles a large amount of VIKING's training programs in casing and tubing design and relevant software applications. He is also heavily involved in engineering projects involving deep water, high pressure, high temperature, and highly corrosive reservoirs.

Peter attended San Diego State University where he was a top Mechanical Engineering graduate. Post graduation, Peter embarked on a Naval career. While in the Navy, Peter taught officer and enlisted personnel the principles of Nuclear Engineering and Reactor Operation at the Navy Nuclear Power School. He also taught Engineering Thermodynamics and Heat Transfer at the United States Naval Academy and Heat Transfer at John's Hopkins University.

Recently, Peter worked with Schlumberger as a Technical Specialist. He was primarily responsible for training internal and external clients to use the Drilling Office software. In addition, he was responsible for technical support and engineering development of the TDAS and WEST software products. Peter, also, conducted casing/tubing design courses as well as assisting IPM, D&M, and WCP with special tubular design projects that require additional engineering analysis.

Thanks to Peter's extensive teaching experience, he is an important member of VIKING training staff. In February of 2002, Peter was an invaluable asset to VIKING's Tubular Design Training School.

John Greenip, P.E.
Consultant

John Greenip has been providing technical analysis and support for a variety of downhole equipment and operations since entering the industry in 1967. More recent projects include HPHT wells, horizontal and extended reach wells, geothermal and steam injection wells, and deep-water applications.

John's initial assignments as a production engineer for a major operator included completion, artificial lift, and workover projects. After spending 4 years with a pumping services company working in sand control and stimulation, he went to work for Hydril in their OCTG applications group. During 27 years at Hydril, his projects included string design, in-house and operator training sessions, product-line planning, and failure analysis.

John graduated from Stevens Institute of Technology with a degree in Mechanical Engineering in 1966. He is a member of SPE and ASME.

John McDowell
Consultant

John McDowell has been in the oil industry since 1982. He spent approximately five years with Schlumberger in electric lines services and has specialized in casing and tubing design for the past nine years. McDowell graduated from Belfast University with a degree in Mechanical Engineering in 1980.

His is fluent in Schlumberger's TDAS stress analysis and WEST thermal simulation models. He has written a series of in-house mathematical models for multi-chamber annulus pressure build-up prediction, kick tolerance, a multi-string assembly and service mathematical model, pipe recovery and stuck point prediction with friction, a vector approach to tubular drag prediction, as well as others.

McDowell is currently based in Aberdeen, Scotland.
