• Attend scheduled meetings with the New Wells Delivery leadership team and technical staff in the Anchorage office as directed
• Proactively train and coach less-experienced personnel

General Operations Responsibilities:
• Collect and review required well site reference data, technical package, correlation / offset logs, maps, prognoses
• Pick casing point: using isopachs, changes in drilling parameters, samples
• Pick core point: using isopachs, changes in drilling parameters, samples
• Perform log correlation/interpretation
• Perform formation and fluid marker picks
• Revise/update geologic marker and target projections

• Experience as a WSG in the Alaskan North Slope
• Demonstrated ability to effectively communicate with wellsite leader (company man), and coordinate activities with directional driller, MWD/logging engineer, mud engineer and office-based geologist
• Strong technical grounding in petroleum operations, operations and production geology, drilling and completions, and field development
• Sound background in basic well log interpretation: with ability to recognize and differentiate lithology, formation fluid responses and borehole effects
• Strong computer skills, particularly with MS Excel
• English fluency required (read/write/understand).
• Must have training with the following
o North Slope unescorted training
