SENIOR GEOLOGIST, OPERATIONS
at Abu Dhabi National Oil Company
Job Purpose
Provide geological operations support for Biogenic-Shallow Gas Project wells includes exploration, appraisal and development drilling projects and G&G related activities. Oversee closely geological operations for active Drilling Program of Biogenic-Shallow Gas Project wells including interpreting subsurface data and to integrate well log and drilling data for decisions and ensure well objectives are met. Interpret drilling reports to aid in assessment of potential geologic hazards and providing geological input for the planned well and implemented in geological marker prognosis and well programs of Biogenic Shallow Gas Project.
Job Specific Accountabilities (Part 1)
• Provide pre drill job preparations such as prepares offset well
correlation panel, attend pre spud or peer meeting, ensures service
contractors to provide tools are operating to their optimum capabilities with
the most cost effective method to meet well objectives.
• Provide technical support and quality oversight for wellsite geology
processes, including mudlogging, LWD/MWD, wireline logging, coring,
directional drilling & stimulation.
• Provide expertise for planning, execution and look-back analysis for all
wells drilled in the vicinity or offset wells, including but not limited to
horizontal wells; also working closely with project geologist/ geomodeler and
geophysicist to optimize the source/data/geological model in order to minimize
the geological uncertainty and providing geological input for the planned
well, incorporated and implemented this information into geological marker
prognosis of Biogenic Shallow Gas Project wells.
• Plan/advice/supervise well design, mudlogging data acquisition,
conventional coring, MWD/LWD, wireline logging, advanced formation evaluation
tools, drilling operation, testing & stimulation, geological markers and
interpretation, along with the integration into well prognosis, well program
and execution.
• Collaborate with geomechanic specialist, reservoir and drilling engineer,
working in applies pore pressure theory and techniques needed to assess pore
pressure, fracture gradient and wellbore stability including advice of
appropriate well design.
• Perform real time monitoring and interpretation of data acquired while
drilling and to integrate these data for decisions. In addition to
interpretation of drilling reports to aid in assessment of potential geologic
hazards and tops selection.
• Maintain open and close communication with project geologist/geomodeler,
petrophysicist, drilling & petroleum engineer, OPCOs operation geologist and
drilling team during vertical, deviated & horizontal drilling operations
following chain of command.
• Oversee sample examination, cuttings collections, petrophysical analysis
and logs, geochemical data acquisition, perforation, testing & stimulation
plans in close coordination with project G&G, petrophysicist, drilling &
petroleum engineering and also OPCOs staff.
• Monitor closely well trajectory plan vs actual and reservoir geology to
ensure the well is on target; also make geological interpretation and
stratigraphic correlation, marker determination and quick look log
interpretation of hydrocarbon zone/ target while drilling; and determine
casing point/ coring point/ logging point/ landing point/ final well TD; also
elaborates with OPCO's operations geologist and geosteering specialist from
service provider while geosteer the highly deviated and horizontal wells in a
24/7 operation basis to ensure a proper placement of wellbore within a
specific target and maximize reservoir contact.
• Provide correlation panel and cross section as may be requested by the
project team, coordinates and QC of geological data acquisition & gathering
while drilling, maintains daily/weekly reporting system for update the
progress of geological operation well drilling, provides technical inputs for
regular management reports.
Job Specific Accountabilities (Part 2)
• Contribute to selection of candidate interval for perforation, testing
and stimulation with integrating all the subsurface data including well logs,
gas while drilling and etc. in collaboration with project petrophysicist,
reservoir engineer and geomechanic specialist.
• Coordinate the coring job from the plan stage, recommendation for core
point determination, establish strategy of core acquisition, core handling &
transportation from site to core store meet the objective in an efficient and
safe manner.
• Finalize the marker and survey elaborated with project geologist/
geomodeler and petrophysicist as needed by the project team and elaborate with
OPCO's operation geologist in input & upload the files into corporate folder/
database.
• Provide the Geological End of Well Reports or Post Drilling Summary
Report of well drilled.
• Support and working closely with the project team and giving contribution
to optimize development plan i.e. provide the well locations, PAD drilling
planning, trajectories plan review and geological model update in order to
maximize field or well potential.
• Operate and enforce safety practices within the operation complying with
company policies, state and federal regulations, also implements company's
health, safety and environmental policy, procedures, regulations and
objectives that related to the Senior Operations Geologist's area of
responsibility, and ensure it are effectively implemented by the junior staff
and support personnel.
• Contribute to geological conventional and unconventional maturation
studies and to participate in the evaluation of well proposals, geological
studies or data gathering activities such as exploration, appraisal and
development wells of Biogenic-Shallow Gas Project, and offer advice when
needed on the scope of the studies and extent of the data gathering
activities.
• Provide input to optimize development plan, provides the well location
and trajectory, PAD drilling plan, trajectories plan review and geological
model update in order to maximize field or well potential.
• Maintains contact with suppliers of geological software, staying up-to-
date with the latest software developments and new applications which are of
potential value to the project.
• Evaluate and recommend to the geology specialist and Biogenic-Shallow Gas
Project Manager about the acquisition of new software and hardware related to
geological studies and added value to the project if needed; also to attend
