Company Overview

Welcome to CNOOC International. We are a global energy company and subsidiary of CNOOC Limited with a vision of delivering safe, sustainable energy for all.

CNOOC International, the international division of CNOOC Limited, is a global energy company with operations in Asia, Africa, the Americas, the Middle East and Europe. Our successful growth as an upstream oil and gas producer has been achieved by consistently finding and developing world-class assets.

Our business is focused on safely exploring and producing from conventional offshore, unconventional and oil sands assets. As part of the CNOOC Group of companies, which span the entire energy supply chain, our size and capability create a competitive advantage that ensures we deliver long-term value.

In Canada, CNOOC International has oil sands assets in Long Lake, located in northern Alberta just south of Fort McMurray, which is a SAGD and partial Upgrader operation with production capacity of 85,000 barrels of bitumen a day. We also have interest in several other oil sands projects, including Hangingstone, operated by Greenfire Resources Operating Corporation and Syncrude’s oil sands mining upgrading facility. In addition to our oil sands business, we have shale gas land in Northeast British Columbia, a power station in Balzac, Alberta, and interest in a wind farm in southern Alberta. Calgary is our regional corporate office for all North America.

CNOOC and You

Your career at CNOOC is about moving forward – learning new skills, broadening experiences, and making meaningful contributions.

Bold ideas, diverse perspectives, and the determination to fuel our success are what set us apart. Therefore, we are seeking a Contractor - Operations Geologist to join our growing team in Calgary, Alberta. This dynamic role will be instrumental in supporting the preparation, execution and post-drill evaluation of geological operations across CNOOC Petroleum North America’s (CPNA) Long Lake and Kinosis assets. The role leads office based geological support and geosteering coordination for assigned drilling programs, provides technical direction to wellsite geologists, integrates real-time drilling and geological data, and communicates geological risks and recommendations to subsurface and drilling teams.

Working across greenfield, brownfield and winter programs, the Operations Geologist ensures that approved geological plans are translated effectively into field execution. The role maintains disciplined operational handovers and decision records, escalates material deviations and subsurface risks, and delivers final well results,



post-drill reconciliation and lessons learned to resource development teams and management.

Please note this is a 12-months contract position through CPNA's contracting agency.

Your Background

- Legally entitled to work in Canada.
- Bachelor’s degree in geology or a related geoscience discipline.
- Professional registration with APEGA as a P. Geol., or eligibility to obtain registration within an agreed period.

- Demonstrated experience supporting SAGD horizontal-well execution and working with the McMurray Formation.
- Ability to interpret LWD, wireline-log, well-correlation and geological-model information in real time and translate interpretations into transparent operational recommendations.
- Sound judgement and the ability to make concise, logical and timely decisions under drilling time constraints.
- Strong written, verbal and presentation skills, including the ability to communicate geological uncertainty, risk and recommended actions clearly.
- Excellent organizational and interpersonal skills, with a demonstrated ability to work collaboratively in a diverse and multicultural setting.
- Flexibility to provide scheduled evening and weekend support during active drilling operations in accordance with established coverage arrangements.
- Proficiency with geosteering and drilling-operations applications such as StarSteer and SOLO, or comparable platforms; working proficiency with Petrel/Petrel Studio and Microsoft 365 applications.
- Experience with both horizontal and vertical wells, brownfield and greenfield projects, wellsite geology oversight, 3D/4D seismic products, Spotfire or Power BI is considered an asset.

Your Role with Our Team

- Exemplify Health, Safety and Environment (HSE) policies, procedures, standards and guidelines in the execution of all work.
- Conduct geological handover of subsurface information, interpretations, risks and approved operating parameters from the brownfield and greenfield teams before execution, including core, log, seismic, geomodel, drilling and production information.
- Review approved coring, wireline, cased hole logging, formation evaluation,



LWD and geosteering programs before execution; confirm geological readiness and recommend adjustments when conditions or data quality warrant escalation.
- Prepare and maintain geological operations packages, including prognoses, target windows, anticipated reservoir impairments, subsurface risks, decision trees, escalation criteria and communication protocols.
- Lead office based geosteering support for assigned wells, integrate real-time drilling and geological data, and provide timely recommendations on well placement within approved operating parameters.
- Escalate material deviations, unexpected geological conditions, data quality concerns and decisions outside agreed tolerances.
- Serve as the primary geological point of communication with the drilling team, field personnel and wellsite geologists during execution.
- Provide technical direction and quality oversight to wellsite geologists and geosteering personnel, including priorities, reporting expectations, shift handovers, data quality, interpretation consistency and compliance with approved geological programs.
- Maintain disciplined handovers across shifts and concurrent rig lines to ensure continuity of geological interpretation, decisions, risks and outstanding actions.
- Document material geological interpretations, operational recommendations, decision rationale and outcomes in accordance with internal requirements.
- Organize the receipt, quality control, storage and distribution of wellsite geological data, files and reports.
- Load and quality check finalized well data in StarSteer and Petrel/Petrel Studio in accordance with internal standards and best practices.
- Understand and apply geological models, well correlations, reservoir impairment interpretations and relevant 3D/4D seismic products when communicating subsurface expectations and risks to drilling and field personnel.
- Prepare and deliver geological content for DWOP, pre-spud, after action review, management and other execution phase presentations.
- Complete post drill reconciliation, final well reporting and structured lookbacks comparing predicted versus encountered geology, well placement and operational outcomes.
- Work collaboratively with resource development, petrophysics, geophysics, reservoir engineering, drilling, completions and production teams to integrate data and improve future well plans.
- Drive continuous improvement by capturing execution learnings, identifying recurring operational issues, improving geosteering and reporting workflows, and incorporating lessons learned into future programs.
- Provide geological information or presentations to the Alberta Energy Regulator when required.
