Achievements:● led a team of highly skilled professionals to develop the world’s first downhole acoustic telemetry system for deepwater offshore oil and gas completion deployments● used latest ASME elastic-plastic design methods including triaxial strain limits and critical plane fatigue to enable atmospheric chambers with a 30,000psi pressure rating● formulated a design strategy that simultaneously met the conflicting requirements of designing for hydrogen embrittlement resistance and high performance elastic-plastic design● simulated the terminal velocity of a dropped object falling inside a pipe filled with a non-Newtonian drilling fluid, developed means and methods to absorb associated impactsCore Competencies:● Downhole tool design ⇨ for challenging HPHT drilling and completion conditions ⇨ getting the most from common downhole alloys ● Multiphysics finite element analysis (FEA) ⇨ structural mechanics incl. post-yielding behaviour, elastic-plastic design, nonlinear materials, contact, buckling, structural dynamics and vibration ⇨ fatigue (incl. strain and critical plane based fatigue life evaluations) ⇨ acoustics (fluids, solids, or both), modelling of acoustics between fluid and solid domains (e.g. sonic tools, microseismic, acoustic telemetry, acoustic ranging, etc.) ⇨ channel modelling for acoustic telemetry ⇨ computational fluid dynamics (CFD), incl. turbulence and non-Newtonian fluids (e.g. drilling fluids) ● COMSOL Multiphysics Certified Consultant (Canada’s only)● ASME BPVC Sect. VIII Div 2 and Div 3, Design By Analysis● Intellectual Property (IP) strategy and portfolio development and managementAvailable for:● Providing technical leadership and oversight to your existing staff to accelerate corporate technology development objectives● Solving particularly challenging problems in wide array of physical realms● Drawing upon vast network of subject matter experts to address a complex challenge

Calgary, Canada Area

● Lead a team of highly skilled engineers in the development of several ground breaking technologies to adapt acoustic telemetry to challenging offshore environments● Developed a low profile yet ultra-high-strength thread design enabling market penetration into some of the world's most demanding drilling conditions● Project Manager: $3M Measurement While Drilling (MWD) tool manufacturing run● Invented mathematical acoustic-waveguide analysis techniques enabling the development of novel equipment in drill string acoustics● Developed a suite of impedance matching transformers to minimize insertion loss of acoustic telemetry devices used in directional drilling of wellbores

Calgary, Canada Area

● Lead Mechanical Engineer on the development of a new electromagnetic telemetry system for directional wellbore drilling (a $1M project that was a cornerstone in a $100M business)● Invented and developed the industry leading gap sub which was acquired by Schlumberger and used extensively in their land based MWD business

Fort Mcmurray, Ab

● Modified the world’s largest vibrating screen using structural dynamics FEA, improving the reliability from months into years (saving well over $98M in production outages)● Used ASME Boiler and Pressure Vessel Code (Sect. VIII, Div. 2) to design an innovative internal patch for a large bitumen separation vessel, which had worn to unsafe limits.Shaved 7 weeks off a severe production outage (resulting in over $340M in savings).● Lead Engineer on a project to mitigate internal corrosion / erosion on the same vessel. Project was completed early and under budget, despite the addition of unplanned repairs.
