Oil and gas production, measurement and revenue accounting is no doubt a complex process.  Unfortunately, Royalty and Working Interest Owners can NOT assume that compensation received for their interest is representative of what they should have received because of the varying lease / sales agreements and operating & accounting practices employed by Operators. Fair compensation is the byproduct of accurate measurement and detailed accounting consistent with the specific individual agreement whether that agreement is an oil and gas lease or pipeline sales agreement.

Faced with the daunting task of negotiating oil and gas leases, Mineral Owners have the opportunity to access Mr. Retzloff’s 25 years of field production, measurement, and well monitoring experience.  Strategies and critical lease language have been developed by TR Measurement Witnessing LLC to make this experience more productive since Mr. Retzloff understands the various production facility layouts employed by Oil Companies that require modifications in accounting practices required to compensate fairly.

Additionally, TR Measurement Witnessing LLC provides services for Oil Companies such as auditing measurement stations & practices to determine if their site security policies and measurement practices are being practiced by field personnel.  Assisting   Oil Companies in troubleshooting and designing down hole pumps for shallow pumping oil wells is a favorite of Mr. Retzloff’s since he has extensive experience in this area.   

In a nutshell, TR Measurement Witnessing, LLC services are structured to maximize Clients revenue from oil and gas flow streams whether the Client is an Operator or a Royalty Owner.
