Introduction to Casing & Tubing Design for Non-Engineers
2-Day Course
The intended audience is for sales and supply personnel, non-engineers and operations personnel who are involved with ordering and supporting the OCTG industry sector.
This 2-day session covers introductory topics in casing and tubing design. The course is structured such that upon completion, participants should have better understanding of:
Casing and tubing design and applications
Why certain weights, grades, and connections are selected for use from a conceptual level
Attendees are encouraged to bring in their own OCTG inventories and tubular issues (both past and present) to use for discussion.

Our Instructors
Barry Cresap
Well Design 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 shortly thereafter and now resides with his family in Katy, TX.
Parveen Sachdeva
Renewables & Special Projects Manager at Viking Engineering
Parveen Sachdeva has over 15 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 & deep-water (HPHT) wells. He is well versed with design software WELLCAT, TDAS & 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 Indian Institute of Technology (IIT Kanpur), and M.S. & PhD in Mechanical Engineering from the University of Central Florida.
