Memorial Resource Development makes management changes

John Weinzierl has resigned as CEO and as a member of Memorial Resource Development Corp.’s (Nasdaq: MRD) board of directors, in order to focus entirely on Memorial Production Partners LP (Nasdaq: MEMP) as its CEO and chairman, positions he has held since 2011. 

The board has elected Jay Graham, former co-CEO of WildHorse Resources II LLC, to replace Weinzierl as MRD’s CEO. Graham was also elected to the board of directors, filling the vacancy created by Weinzierl.

Graham has 23 years of experience in the oil and gas industry, notably with Halliburton, Devon Energy, and Anadarko Petroleum in various technical and leadership capacities. In 2007, he co-founded WildHorse Resources LLC and subsequently acquired Petrohawk Energy’s interests in Terryville Field in 2010. WildHorse Resources drilled the initial horizontal wells in Terryville Field and operated as a subsidiary of MRD prior to MRD’s initial public offering in 2014. Graham has a Bachelor of Science degree in petroleum engineering from Texas A&M University.

Memorial Resource Development Corp. is an independent natural gas and oil company engaged in the acquisition, exploration, and development of natural gas and oil properties primarily in North Louisiana.
