Our Instructors
Barry Cresap, P.E.
Well Engineering Director
Barry has over 20 years of oil and gas experience, primarily working as a principal drilling engineer and manager over a wide range of campaigns and rig types for both land and offshore. His engineering experience spans across both conventional and unconventional designs and operational practices including deepwater, shelf, and horizontal drilling. He began his career with ENSCO and completed a 3-year “fast-track” superintendent program which entailed working rig-based positions from crane crew, drill crew, up tonight toolpusher on jack-ups in the Gulf of Mexico. He broadened his experience at Grey Wolf / Precision Drilling while executing turnkey contracts all along the US Gulf Coast.
He joined BHP in 2012 in the Eagle Ford as a Senior Drilling Engineer and moved up to Drilling Manager. He joined the offshore division in 2014 and executed a deepwater exploration well in Central GOM (4,200 feet WD) in 2017 to 32,000’MD. He moved internationally to Perth, Australia in 2019 - 2021 to plan a multi-lateral campaign (12,000 feet laterals) along Australia’s Northwest Shelf. He and his family have since returned back to the US. He left BHP in 2021 with the merger acquisition by Woodside. He joined Viking Engineering shortly thereafter and is now working as the Director of Well Engineering and now resides with his family in Katy, TX.
Parveen Sachdeva, Ph.D.
Renewables & Special Projects Manager at Viking Engineering
Parveen Sachdeva has over 18 years of oilfield experience. His expertise is in critical well design, flow assurance modeling and thermal analysis of wellbore heat transfer. At Viking Engineering, he has been involved in projects for casing design of class IV & class IV CO2 Injection (CCUS) wells, high temperature geothermal wells, casing and tubing design of shale gas wells and deepwater (HPHT) wells. He is well versed with design software WELLCAT, TDAS and StrinGnosis, and flow assurance software WELLFLO. His research interests include thermal well design including steam injection and high temperature geothermal wells. Sachdeva has authored or coauthored 8 technical papers and holds 1 US patent. He received his B.S. degree in Aerospace Engineering from the Indian Institute of Technology (IIT Kanpur), and a M.S. and Ph.D. in Mechanical Engineering from the University of Central Florida.
Mario Guerra, P.E.
Director of Lab & Failure Investigation
Mario has over 20 years of experience in the areas of metallurgy, welding engineering, failure analysis, corrosion engineering, environmental assisted cracking, fracture mechanics, sour service fit for purpose testing and evaluation, materials specification development, and HPHT equipment materials engineering design.
Peter Erpelding, P.E.
Tubing & Completion Design & Training Lead
Peter is a consulting engineer for Viking Engineering and specializes in mechanical and thermal analysis of drilling and completion equipment. Mr. Erpelding is heavily involved in engineering projects involving deep water, high pressure, high temperature, and highly corrosive reservoirs. He has conducted numerous software training courses and casing/tubing design seminars. Prior to working for Viking, he spent four years with Schlumberger, and seven years with OTS. He has an additional seven years of teaching experience in the fields of Reactor Physics, Thermodynamics, and Heat Transfer. He has served on the faculty of the U.S. Naval Academy, U.S. Naval Nuclear Power School, and Johns Hopkins University.
