Reservoir Engineer

We are seeking a Reservoir Engineer with Specialization on Ultra Tight/Tight Sand & Channel Reservoir to join our Unconventional Reservoir Management Division (URMD) of Unconventional Reservoir Engineering Department (URED).

URMD is responsible to provide technical expertise to optimize unconventional resource development, focusing on reservoir characterization, modeling, and management. Key responsibilities include well evaluations, play assessments, production forecasting, and developing field plans for ultra-tight and channel sand reservoir.

Your primary role is to develop and manage the Kingdom’s Unconventional Resources at the most optimal unit cost through applying best-in-class reservoir management and development strategies, built on sound economics, to maximize shareholder returns.

As the successful candidate you will be required to perform the following:

\n
• Design and implement solutions for depletion strategies, reservoir performance analysis and field development plans for unconventional resource plays.
\n
• Study reservoir and well performance data and develop/supervise reservoir surveillance programs and reservoir management activities.
\n
• Supervise and support comprehensive fracture modeling and simulation studies to identify optimal well spacing, completions design, unconventional reservoir management strategies and opportunities.
\n
• Organize and lead multi-functional peer reviews to support and improve field development design.
\n
• Monitor operating expenses to operate and maintain wells to produce the highest volumes of oil and gas at the lowest cost.
\n
• Prepare annual activity volumes and expenses for budgeting purposes.
\n
• Monitor and analyze well tests and production curves.
\n
• Gather, perform calculations on and analyze data such as well tests, fluid levels, bottom-hole pressures, and decline curves to assure efficient producing and equipment utilization.
\n
• Work closely with multidisciplinary team in planning and conducting reservoir field studies.
\n
• Prepare requirements for well construction, develop well designs for new wells and provide technical assistance to drilling staff to ensure safe and efficient well completion.
\n
• Provide economic evaluation to support fast-paced development decisions and work closely with drilling, completions, and production teams.
\n
• Develop and implement efficient reservoir engineering and organizational practices.
\n
• \nProvide on the job coaching and mentoring to help develop capabilities of team members enabling them to grow technically and perform their job effectively and efficiently\n
\n

As the successful candidate you will have:

\n
• Petroleum Engineering degree from a recognized and approved program. An advanced degree is preferred and will reduce prerequisite work experience stated below by one year for master degree and two years for PhD.
\n
• Minimum of 10 - 20 years of experience with at least 5 years in unconventional plays including shale or tight gas/condensate or channel reservoirs, with international experience in unconventional hydrocarbon basins required.
\n
• Understanding of stimulation programs design, open hole and cased hole logging capabilities, well test analysis (Pressure transient analysis and rate transient analysis), decline curve analysis, dynamic reservoir modeling, reserves classification, EUR predictions, well spacing and landing zone optimization.
\n
• Required to support key development decisions.
\n
• Knowledge of the following applications is required: IHS Harmony and Explorer, Kappa Workstation Suite (Saphir, Topaze minimum), Whitson, ECLIPSE, Kinetix, GOHFER, Resfrac, Petroleum Expert, CMG, Peep, PVTsim and EOS modeling is preferred. Knowledge of Analytics and Artificial Intelligence is appreciated.
\n
• Demonstrated ability to work in a fast-paced environment and manage ambiguity in analysis.
\n
• Solid organizational and time management skills, with the ability to work with limited data.
\n
• Ability to generate Management Reports and Data analysis experience.
\n
• Solid understanding of business planning, including economic analysis and project management.
\n
• Familiar with field development / economic concepts with a broad knowledge in drilling, completions, and reservoir stimulation technologies with understanding of horizontal multistage fracturing for unconventional reservoir
