The Company:
Our client is a leading global oil and gas operating company.

The Role:
The Wellsite Geologist (WSG) will work a mutually agreed rotational schedule in support of Company’s production and development drilling operations on Alaska’s North Slope. The WSG’s primary responsibility is providing onsite, real-time geologic interpretations, active geosteering and operational support during drilling. The role also demands pre-drill technical review and preparation to ensure successful well delivery; regular reporting during well execution; logging quality assurance; and post-drill documentation. Drilling operations include “grassroots” rotary wells, rotary rig sidetracks (RST), and coiled tubing drilling sidetracks (CST). Well types include vertical, extended-reach, high-angle slants, and horizontal wells (single and multi-lateral) targeting various reservoirs in fields operated by Company on Alaska’s North Slope.
The WSG is an integral part of and reports to Company’s New Wells Delivery (NWD) team in its Anchorage office. The position demands close and regular interaction with wellsite team leaders, onsite rig personnel, NWD and other subsurface functional teams in Anchorage.
Awareness and adherence to Company HSE policies and Code of Conduct

• Attend pre-spud meeting(s) in Company’s Anchorage office, with NWD and review technical package and statement-of-requirements (SOR) objectives and drilling program
• Collect and review required well site reference data, technical package, correlation / offset logs, maps, prognoses
Onsite Operational Responsibilities
• General
o Pick casing point: using isopachs, changes in drilling parameters, samples and logs
o Pick core point: using isopachs, changes in drilling parameters, samples and logs
o Log correlation/interpretation and quality assurance
o Formation and fluid marker picks
o Revise/update geologic marker and target projections
o Geo-steer wellbore to achieve objectives of SOR
o TD determination
o Wellbore landings and target adjustments to drill data
o Forward projections and real or apparent thickness corrections
o Fault recognition and characterization
o Mentoring and training of less-experienced personnel
• Cuttings sample evaluation and description
o Reservoir characterization: general lithology, grain size, sorting, roundness, porosity, consolidation, cementation
o Hydrocarbons show analysis and description: stain, visual cut, surface fluorescence, cut fluorescence, percentage of HOT (heavy oil / tar) occluding porosity
o Sample quality control and documentation
• Log Quality Control
o Depth control and log tie-in on sidetracks (rotary or CT) and conventional wells
o Provide onsite quality control for MWD / Wireline / Drill Pipe Conveyed logs
o Provide logging service company with log normalization zones
o Witness CH log acquisition and provide quality assurance e.g. CNL, CBL, USIT
• Communication
o Advise town personnel on drilling and well execution status and propose changes in well plan as necessary
o Advise rig team on geologic risks, attend morning meetings and any others as needed or requested, advise rig team on casing point
o Advise directional driller on target objective(s) and geosteering requirements, and proactively direct changes or adjustments in well trajectory to ensure objectives are met
o Advise MWD and mud logging personnel of program requirements and revisions; provide quality assurance for same
o Distribute daily reports, files and interpreted data to Operator’s designated representatives and others as approved and directed by Company
o Regular and routine interaction with NWD operations geologist
o Regularly visit New Wells Delivery team and others in Company’s Anchorage office

o Daily Reports, interpreted “Geosurvey” (using Company-supplied application), lithology description
o Interpreted daily MWD log with target projections
o Final perforation recommendations in collaboration with Town subsurface team(s)
o Prepare final geologic operations report (End of Well Summary), interpreted log and digital log file(s)
o Maintain North Slope geology and engineering files; expedite final logs and data to Anchorage

Essential Skills / Qualifications:
