Job description

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 conferences, seminars and to review technical periodicals.
