All assets of Mount Sopris Instrument Company were acquired by the owners of COLOG in 1991 from EG&G Geometrics (Sunnyvale, CA). 100% overlapping ownership with COLOG.I served as an officer of the Corporation and the Technical Director. I was responsible for all phases of design, manufacturing, sales, and delivery to the final customer. Major clients both in the USA and worldwide. Commissioned a complete well logging truck and trained the operators and interpreters for the Electricity Generating Authority of Thailand (EGAT) in Lampang, Thailand.

Wireline service Company previously known as Colorado Well Logging, Inc.Primarily serving the environmental, minerals, and water resources markets with borehole geophysical and hydrophysical measurements and interpretations.Mt. Sopris Instrument Company had the same ownership as COLOG from 1991 to 1997. Currently COLOG is a division of Layne Christensen.

Developed a PC-based well log data acquisition and processing system as an add-on to existing analog well-logging systems from a variety of manufacturers. Merged with COLOG in 1987 and continued development, sales, and support of over 100 systems. This system was a key in the acquisition of Mount Sopris Instrument Company from EG&G Geometrics in 1991, and was the foundation of the Mount Sopris digital system.
