We are one of the most profitable companies in the world, as well as amongst the top five global companies by market capitalization.

Overview

We are seeking a Reservoir Engineer to join our Unconventional Reservoir Management Division.

Unconventional Reservoir Management Division 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.

Key Responsibilities

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

• Design and implement solutions for depletion strategies, reservoir performance analysis and field development plans for unconventional resource plays.
• Study reservoir and well performance data and develop/supervise reservoir surveillance programmes and reservoir management activities.
• Supervise and support comprehensive fracture modelling and simulation studies to identify optimal well spacing, completions design, unconventional reservoir management strategies and opportunities.
• Organise and lead multi‑functional peer reviews to support and improve field development design.
• Monitor operating expenses to operate and maintain wells to produce the highest volumes of oil and gas at the lowest cost.
• Prepare annual volumes and expenses for budgeting.
• Monitor and analyse well tests and production curves.
• Gather, perform calculations on and analyse data such as well tests, fluid levels, bottom‑hole pressures, and decline curves to assure efficient producing and equipment utilisation.
• Coordinate all aspect of new completions, especially design of fracture stimulation.
• Work closely with multidisciplinary team in planning and conducting field studies.
• Prepare requirements for well construction, develop well designs for new wells and provide technical assistance to drilling staff to ensure that each well is completed in a safe and efficient manner.
• Provide economic evaluation to support fast‑paced development decisions and work closely with drilling, completions, and production teams.
