Coordinated activities and handled critical issues with Rig Supervisors, Operations Superintendents, Drilling Supervisor, and Drilling Manager. Project Accomplishments:

• Analyzed existing limits to drill the longest lateral in the Eagle Ford at 10,112ft in a single run (curve and lateral sections), achieving 20,679ft TD, 1,310 feet per day, and $127 cost per foot (Wheeler MCM X 1H).

• Utilized innovative technology to float 5- ” production casing via AirLock sub saving 8 hours per well.

• Set a 24 Hour Footage Record in the Eagle Ford tangent section (4,691ft with 200 ft/hr ROP) by optimizing bit selection and drilling parameters.

• Improved Nomac 131’s rig performance in Cost per Foot and Feet per Day metric from bottom quartile to top half of the rig fleet through analysis of offset rig performance and open communication with field personnel.

EXXONMOBIL CORPORATION Houston, TX 2008 - 2014

Drilling Project Engineer, Western Canada Drill Team, Calgary, AB 2012 - 2014 Supervised drilling of Oilsand Valuation Winter Program (2 seasons, 60 wells).
