Midstates Petroleum Co. Inc. (NYSE: MPO) said June 7 that Nelson M. Haight, executive vice president and CFO, will resign to explore "other opportunities in the E&P sector."

Haight has been with Midstates for about six years. Prior to being named CFO in January 2014, he served as the Tulsa, Okla.-based company's chief accounting office beginning in August 2013 and vice president and controller beginning in December 2011.

Jake Brace, Midstates president and CEO, commented: “Nelson has contributed a tremendous amount during his tenure at Midstates and he has provided outstanding leadership and guidance during a very critical time for the company.”

Previously, Haight was a partner with the audit firms of GBH CPAs and Malone Bailey. His resignation from Midstates is effective June 15.

In May 2016, Midstates filed for Chapter 11 bankruptcy protection. The company completed its restructuring and emerged from bankruptcy in October after reaching agreements with significant groups of creditors to eliminate roughly $2 billion of its debt.

So far in 2017, Midstates has been focusing on its Mississippian Lime assets with a one-rig drilling program in Oklahoma and also recently began trading on the New York Stock Exchange.
