I am the primary contact with independent third party reserve auditors & the Reserves team representative working with internal and external audit firms. Wrote procedures and initial documentation for Sarbanes-Oxley compliance.Worked closely with Finance and our PE sponsors to perform asset modeling at different development sensitivities (rig count, CAPEX, pricing, etc) in ARIES, then outputs into Excel based formats for integration into Financial models including complicated joint-venture, side-car, and other financial instruments. Member of A&D team, evaluating opportunities including large acquisitions, small bolt-ons, acreage trades, and divestitures. Have prepared data room materials including outputs of cash flow models, scrubbed ARIES databases, and public and dataroom PowerPoint slide decks.Monitored day-to-day operations over half of Sable Permian Resources large southern Midland Basin acreage position, as it has grown from 138 horizontal PDP wells to over 550 during tenure. This includes building type curves, evaluating economics on AFEs, building development plans & budgets, working with Geoscience to recommend drilling targets and locations, advising Operations on day-to-day planning including stimulation sizes, artificial lift selection, workover candidates, and more.

June 2014 - March 2015: Primary reservoir engineer for Uinta Basin Oil Properties group consisting of 232 operated and 83 non-operated PDP locations and a two-rig drilling program. Duties consisted of analysis surrounding capital expenditures, downspacing, recompletions, budget development programs, SEC reserves, 3P buildouts, and monitoring offset operator activity.July 2013 - March 2015: Reservoir engineer assigned to Powder River Basin (19 operated and 88 non-operated PDP locations). Primary duties include non-op proposal evaluation and surveillance, budget planning, SEC reserves evaluation and 3P buildouts. PUD bookings were revamped due to offset operator performance and shift to long-lateral completions, especially in Frontier & Shannon formations.January 2015 - March 2015: Worked as secondary reservoir engineer in a support role in the Denver-Julesburg Basin, northeast of the Wattenberg.February 2014 - December 2014: Worked in Business Development group on divestiture of Powder River Property. This position has included close ties with outside A&D consultants on establishing both an in-house physical and a virtual data room, gathering and organizing data relevant to the sale process, answering data room participant questions, while continuing in day to day responsibilities for Powder River Basin operations.

Sept 2008 – July 2013: Reservoir engineer assigned to Anadarko & Arkoma basins (over 500 operated and 450 non-operated properties). Working primarily on base production maintenance projects, including recompletions and other uplift projects, and evaluation of outside operated proposals. Developed five well pilot vertical drilling programs in 2010 & 2013 for Anadarko Basin oil wells. Built inventories of future drilling locations and behind pipe recompletion opportunities. Performed preliminary studies into two potential waterflood units. Performed A&D evaluations for both large scale (500 MM$+) and small scale propertiesJanuary 2012 – July 2013: Responsible for an additional 1000 wellbores in large scale waterflood properties newly assigned to the Oklahoma City office including South Graham Deese, Naval Reserve Unit, Lisbon Petit, and Velma Camp Deese units. Performing evaluation for capital investment or monetization potential of properties while high grading injector and producer workovers, reactivations, and building an inventory of infill drilling locationsJuly 2011 – December 2011: Evaluated Carr interval Granite Wash in Stiles Ranch of Wheeler County, TX for horizontal drilling opportunities. Performed standard reservoir engineering pre-drill analysis then completed two successful testsSeptember 2008 – July 2009: Performed detailed reservoir analysis in joint venture with Laredo Petroleum overseeing distal granite wash drilling in Hemphill County, Texas. 63 wells drilled, in that time, ramped production up from 24 MMCFE/day to 57 MMCFE/day

Oversaw a 32 rig drilling program in the West Texas Overthrust Piñon Field, averaging 1 well completion/day with production ramp up from 95,000 MMBTU/day to 165,000 MMBTU/day over 14 months including working with Geology to prospect new well locations outside of the core drilling area.Developed reserve and capital cost documentation for Sarbanes-Oxley reportingUpdated and monitored ARIES well databases
