There isn’t any one who isn’t impacted by the continuous growth and changes in the world of technology. In today’s world, we accept computers and the functions they perform without question. In fact, we place our hardearned dollars and in some cases our very lives in their care without a second thought. Computers and electronic technologies have greatly impacted the way work is done in the oil and gas industry. A good example of how these changes have impacted this business is the use of electronic gas measurement devices often called (EFM’s). With the use of the EFM, and associated electronic equipment, we not only have the option to measure gas volumes but to retrieve required data instantly and enhance production through well automation. As in any business, before the decision is made to upgrade or change from the standard method of measurement using the typical dry flow chart recorder to EFM, the economics of such a decision needs to be evaluated. It is becoming common practice to install EFM on all new measurement stations. The real battle over economic justification seems to be in the decision to replace meter stations, which already have chart recorders in place with EFM’s. You will find that the economic justification of using EFM is often difficult to quantify
