Providing Innovative Geologic and Surface Logging since 1964

The Company was formed as Midwest Well Logging in December 1964 by Hoyt Hudspeth and Harold McConnell. Hoyt and Ruthe Hudspeth purchased all of Harold’s interest in 1972 and renamed the company Petroleum Well Logging, Inc. It operated under that name until 1987 when the name as changed to Petroleum Mud Logging, Inc (PML).

The Company’s extensive client base attracted the attention of Rentech, Inc., a Denver, Colorado base corporation, in early 1999. Rentech purchased PML in June 1999. New management was installed and an electronics consultant was retained to design a new state of the art gas monitoring system that utilized the latest electronics technology.

In November 2006, Petroleum Mud Logging, Inc. was purchased by a private investment group and renamed PML Exploration Services LLC. The name change was made to better reflect the long term goals of the company.

In November 2015 the management team of PML purchased the assets of PML and formed EDGE Finance, LLC. Both EDGE Systems and PML Exploration Services continue as dba’s of EDGE Finance.

EDGE Systems develops gas analysis and rig data management solutions for use by it’s own mud logging division and for rental to others. These solutions provide secure web based information to energy companies on a real time basis.
