 Co-engineer over the Miss Lime assets, managing over 400 horizontal wells on ESP, GL, GAPL, and ESPCP which includes Alfalfa County, OK and Woods County, OK. Worked with team of reservoir engineers, geologists, and geophysicists to develop most efficient methods to produce wells that IP’d up to 4,000 BFPD and declined to 300 BFPD within 2-3 years. Prepared recommendations, AFEs, and schedule for up to 10-rig workover program to perform wellbore cleanouts, acid treatments, and artificial lift repair Negotiated contract with chemical provider for savings of over $200,000 per year on emulsion breaker and methanol. Negotiated contract with ESP provider for 20% reduction in cost, resulting in annual savings of $4,000,000 Worked with field personnel to refine ESP design and operating philosophy to achieve average run life of 22 months Provided support for new well planning, including design of production facility, SWD infrastructure and power grid Provided guidance to field personnel on daily production activities, including management of production rates, reduction of downtime, well treatments, and artificial lift optimization Organized periodic well reviews with geologists, reservoir engineers and field personnel Evaluated economic feasibility of projects for workover program by using simplistic payout calculations. If criteria were not met, then the AFE was handed off to the Asset department for ARIES evaluation. Improved fieldwide production by 10% or 2,000 BOEPD by implementing alternative artificial lift methods such as GAPL and ESPCP Helped cut LOE and downtime by 10% (i.e. power grid improvements, VSD set point changes, and facilities redesign) which saved $400,000 per year Performed detailed process flow and economic analyses for comparisons of surface facilities designs. Initiated a seat drill out, wellbore cleanout, and wellbore acidization program that caused a 15% increase in fieldwide production or 3,000 BOEPD

 Lead engineer over the Hunton dewatering assets, managing 40 horizontal wells on ESP which included Lincoln County, OK Performed chemical analyses on produced water and initiated a capillary tube scale inhibition program that led to a 50% increase in fieldwide production or a 500 BOEPD increase. Negotiated contract with chemical provider for savings of over $50,000 per year on scale inhibitor and H2S scavenger Returned 5 wells to production that were slated for TA by performing wellbore acid stimulation and casing swedge jobs which led to a 10% increase in fieldwide production or a 100 BOEPD increase Implemented alternative H2S scavenging contact time lengtheners which increased the efficiency of triazine and led to chemical savings of $20,000 per year.

 Lead engineer over the Anadarko Basin assets, managing over 300 horizontal wells on RL, GL, and PL Monitored production rates, fluid levels, dyno cards, and planned workover processes to improve production Reactivated over 20 wells slated for PA by implementing wellhead compression assisted PL Helped redesign rod strings for more efficient operations using RodStar

 Designed and supervised drilling operations in DJ Basin CO and Gulf Coast LA. Including researching offset drill rates, bit use, mud reports, and completion styles. Performed cost analysis on drilling rig companies and supporting services, performed pre-spud meeting, and assisted Company Man as engineer on site.  Designed and supervised completion operations in DJ Basin CO and Arkoma Basin. Planned and assisted Company Man as engineer on site over Arkoma frac job in the Atoka. Documented failure of frac equipment which led to complete screen out. Supervised the cleanout of the wellbore, and wrote the rough drafts of the legal documents that were sent out to the frac company in question. Proceeded to negotiate with frac company for full repayment of frac costs.  Designed and supervised technically challenging workovers from Operations Engineers across the MidCon (AR, CO, KS, NE, and OK) including fishing jobs, hole in casing diagnosis, hole in casing repairs, cement squeezes, and wellbore cleanouts Reviewed and streamlined all company workovers by tracking AFE costs, rig trip times, and safety practices using a detailed spreadsheet to discover which regions had more efficient workovers and why. Used the knowledge to better the workover practices company-wide and saved an average of 0.5 days per workover, or roughly $400,000 per year Organized regulatory and compliance, frequently submitted paperwork to COGCC, OCC, KCC, and LA DNR

 Supervised workover rigs, roustabout crews, and pumper schedules for over 1,000 vertical wells across the DJ Basin which includes Jefferson County, CO, Arapahoe County, CO, Adams County, CO, Weld County, CO, Morgan County, CO, Boulder County, CO, Kit Carson County, CO, Yuma County, CO, and Morrill County, NE Lowered operating costs and improved net profit by creating a more efficient pumper schedule saving $50,000 per year Performed Company Man role over up to 3 active workover rigs, filling in as rig hand or derrick hand on occasion. Performed surface equipment repairs, ran pumper routes on weekends, and conducted maintenance as needed on rod lift engines, rod lift clutches, water dumps, master valves, etc.

 Maintained and improved upon production by enhancing efficiency of over 1,000 vertical wells on RP, PL, and ESP across the DJ Basin which includes Jefferson County, CO, Arapahoe County, CO, Adams County, CO, Weld County, CO, Morgan County, CO, Boulder County, CO, Kit Carson County, CO, Yuma County, CO, and Morrill County, NE Analyzed and diagnosed reasons for lowered production using dyno cards, fluid level surveys, and pumper production data.  Converted a mature waterflood from rod lift to ESP and saved $100,000 per year in workover expenses Designed and implemented secondary stimulation on Codell and Niobrara wells using isolated tubing to protect degraded casing from frac pressures.  Initiated an acidization program that increased production by 500 BOEPD Determined economic feasibility of projects in PHDWin  Organized regulatory and compliance, frequently submitted paperwork to BLM, COGCC, and NOGCC
