Philip R. "Rusty" Rice - VP Land
Sydri Energy Group - Dallas, Texas

“JIMAR assisted my company with the gulf coast asset from Linn Energy in 2017. The due diligence conducted was very detailed. We acquired two fields and over 150 wells which we acquired minerals and overriding royalty interest under. The two fields were legacy fields discovered in the 1940 and 1950. They provided excellent work product including Acquisition Folders on each field which reduced ongoing work. Then they did the DD for another acquisition we did in 2021. Again they provided a very skilled team and did a great job. They are also very helpful on day to day operations after the DD is completed. I recommend JIMAR”

Often we worked multiple acquisitions concurrently. JIMAR's work was always performed timely under tight deadlines with the transactions closing on time.
