History and Applications


When Hg became an environmental exposure health concern, which made obsolete the traditional method, a major oil company contacted Emdyne, Inc., in the 1980s, to provide the design of a mechanical volume recording instrument for their core flood laboratory studies. After about a 2- year development phase, a first generation design reached completion and numerous iterations were built for the client's use in their enhanced oil recovery research labs. The design proved to be reliable and an asset to in-house research programs. A patent was granted the design during this period. These early models used flexible tubing for internal plumbing and combined the electronic controls and collection plumbing within a common housing that lacked temperature control and data interfacing. The current model 2015 PGM owes its present form and function thanks in large part to the collaboration of another industry leader in geological core analysis.

When this new company became aware of a PGM example in Canada in the late 1990s, a call came to Emdyne to see about redesigning the original model to include necessary upgrades: stainless plumbing, heat control and data reporting. A thorough redesign program then ensued, a prototype was made and tested, further changes were added and a final design arrived about the year 2000. The MK 2015 model without temperature control is the newest standard offering. Temperature control is now an additional cost option.

Although the Emdyne, Inc. PGM has been used primarily for core flood studies in the oil and gas business, other fields may find its unmatched capabilities very useful.
