David Lewis is currently the President and CEO of Blade Energy Partners.  He has over 30 years of domestic and international experience in oil & gas exploration and production.  He has a management and a strong engineering background in drilling, completions and offshore structures with experience in deepwater, big bore (mono bore) and high pressure - high temperature wells (surface pressures of 30,000 psi and surface temperatures of 450 degrees F).  He has specific expertise in technology management, deepwater drilling, HPHT wells, reliability-based design, tubulars, connections, marine drilling risers, conductors, pipelines, offshore structures, down-hole equipment, project management, training and finite element analysis.  He was with Mobil from 1981 to 2000 and Blade from 2000 to present day.  At Mobil he led the development of Mobil’s reliability-based tubular design technology, deepwater floating drilling technology and he developed and taught Mobil’s casing design, floating drilling and advanced mechanics courses for many years.  David’s current interests include quantitative risk analysis and reliability-based design, as well as stochastic optimization methods applied to the oil and gas industry.  He is very active in API and ISO committee work serving on seven different committees and is the current chairman of API Committees:  API 5-EX (Solid Expandables), API RP 16Q (Marine Drilling Risers) and API 16R (Marine Drilling Risers Connectors).  He has over twenty five archival publications in various areas of tubular mechanics and structural engineering.  He is a Registered Professional Engineer in the State of Texas, and a member of ASCE and SPE.  In 2009 and 2010 he served as a Distinguished Lecturer for SPE.  Education includes BS and MS degrees in Civil Engineering from University of Missouri-Rolla.

Full Description
Traditional design approaches, including working stress design, have served our industry well for decades. In recent times, with an increase in deeper, hotter, and more complex wells, the Industry has encountered the limitations of traditional design approaches that often imply either the impossibility of design, or force engineers to make subjective compromises in the design. More sophisticated alternative design approaches are needed, primary among which is reliability-based design.
This lecture focuses on the application of reliability-based design for complex wells. Traditional design approaches and their limitations are reviewed briefly. The evolution of design to limit states, as exemplified by the recent ISO TR 10400 and API TR 5C3 documents for casing and tubing is discussed in some detail. The rationale for reliability based design is introduced. The rigorous statistical basis and the standards that govern the development of reliability based designs are discussed and placed in the context of the natural tolerance and aversion of a society to risk. The concept of "Design Levels" based on the sophistication and probabilistic nature of the approach is introduced.  Finally, it is shown that reliability based design approaches are standard in virtually every other structural and civil design disciplines, with our industry being a late adopter of this critical enabling technology.
