Halliburton Inc, Houston, TX

Nov 2005 – Jan 2018

R&D Mechanical Engineering Advisor, Sperry Drilling Services

• Designed and developed mechanical packaging solutions for electronic components in next generation push the bit rotary steerable tools. Electronic sections housed the rectifier, inverter, housekeeping power supply, capacitor bank, bus bar, Gamma sensors etc.

• Performed thermal simulations to optimize electronics housing designs to achieve efficient dissipation of heat into the drilling fluid. Maximum temperature rise of electronics components were maintained to be less than 25-degree C to survive downhole drilling environment.

• Supervised thermal and structural simulation studies performed by third party vendors and analyzed results to identify optimum design options.

• Performed lab tests such as shock, vibration, pressure verification etc. on various modules of rotary steerable and downhole imaging tools.

• Identified and documented efficient assembly methods of downhole tools that are used in prototype and production assembly floors.

• Liaised with in-house and third-party material testing labs to analyze and qualify various elastomers for optimum packaging of rotary steerable and imaging tools.

• Worked closely with vendors to design and build component parts, 3D printed test parts and to procure prototype machined parts.

Product Development Engineer – Halliburton Drill Bits & Services, Woodlands, TX
