I have worked for a series of petroleum exploration-related companies in the Houston Area, including Dresser, where I commercialized the design of an intrinsically safe battery-operated stroke rate meter (which was my M.Eng. project) and other drilling rig instrumentation, and Western Atlas where I was manager of Acquisition Systems, designing large arrays of towed marine seismic acquisition streamers, seismic sources, and land acquisition systems.
I worked for a few years for Input/Output, another seismic company, and then for Syntron and Sercel, competitors of Input/Output, designing more seismic acquisition systems.
Currently, I have more of a design/project manager position rather than in engineering management, working for Weatherford Int'l. on smaller projects using optical sensing---all fiber optic sensors for flow, pressure, acceleration, and temperature in deep downhole environments and surface interrogators for the optical sensors.
