LEMS What?




  • LandMasters (LEMS) creatively designed and integrated a land management suite and it’s a game changer. 
  •  While the collection of data during the exploration for oil and gas has been conducted the same way for over one hundred years, most Landmen now communicate using cell phones, pads, emails, texts and many use Excel for calculations. Times have changed, but - there is still no one resource available for explorers. You need flexibility.  Login to a LEMS secure cloud network and input, organize and share complex data. No problems, use LEMS.

Upcoming event - Launch date set for March 17, 2010

  • LandMasters (LEMS) has engaged in several years of research of oil and gas exploration during the Bakken Oil & Gas Boom and Decline between 2008 and 2014-16.  Resulting is some important revisions to the calculation segment of the LEMS program which now accounts for Oil & Gas Mergers and Acquisitions, enhanced reports and communication methods.
  • We have retained a cloud systems engineer for additional infrastructure support and security. These revisions have significantly impacted the original 2011 software and its updates. A new launch is expected on 03/17/2020 and will match the current trends in our the industry.

A Need for LandMasters

  • Research shows that sixty-five percent of landmen are under thirty-five years old, while the rest are fifty-five and older. Further a Microsoft survey found 73% of those who responded are ready for software technology in the upstream market.
  •  To address this technology gap LEMS provides a cost control application for E&P land management providing communication, collaboration and calculation tools for regionally dispersed land professionals or royalty owners. 
  • This one resource unites diverse team members by allowing the transfer of information directly into the web where projects are near-instantly updated for review 
  • Operators can drill down and know, on a daily basis; who is working and who is not, how many acres have been leased and how much it cost, what interest a Land Owner owns and in what plot of land. The basic format of this information will rapidly advance projects and provide accountability. 
  • Royalty Owners have many options too. For example, they can ask to become a user on an Operators LEMS account for information directly affecting their individual interest in a producing or non-producing well. Or, they can directly purchase LEMS to help manage their Royalty Interests and add others as wanted or needed. Upload; Property Records such as Deeds and Assignments, Division Orders, Probate Documents or anything that relates to ownership.
