Location & Business Unit Overview

Discovery House, Aberdeen

Position Overview
  • Lead the reservoir engineering activity for the asset. Provide support to the asset for all Reservoir Engineering aspects, including, but not limited to, simulation model build, well test analysis, forecasting, reservoir management, well planning and fluids analysis.
  • It is the duty of the reservoir engineering part of the asset team, and in particular the lead reservoir engineer, to be responsible for maximising the value of the asset.
Job Duties & Responsibilities
  • It is a key part of the Lead Reservoir Engineer’s role to come up with good ideas, either to enhance the value of the field, such as EOR or infill drilling, or through a risk mitigation measure such as data gathering. The engineer should suggest ways to improve the asset in the spirit of continuous improvement
  • It is up to the Lead EGGs to communicate the status of the field to the SSTL and the ADM. The Lead Engineer should work with the other asset team members in a collaborative style and present to JV partners, management and other as required.
  • The lead reservoir engineer will be expected to insist that reservoir engineering tasks are performed to an agreed standard. There should be no exceptions to this rule. Although time is often limited, any task should be performed to a minimum standard and this should not be compromised. Typical tasks include:
    • Reservoir simulation expertise: running existing models; modifying existing models; creating new models. Gathering and verifying input data should always be 80% of the task.
    • Uncertainty analysis: any significant project should be considered in a probabilistic manner. Ranges should always be considered; use of probabilistic tools such as Crystal Ball or MEPO is encouraged. The concepts of Decision Analysis need to be understood and the use of decision trees and explicit definition of risk factors is encouraged.
    • Well test analysis. Any analysis will be non-unique, and the amount of information that can be derived will be dependent on the quality of the data.
    • Well planning. The value of future wells should be estimated in close collaboration with the rest and the team, in particular the G&G community.
    • Nodal and network analysis. Although the Production Engineering community will own the nodal and network analysis, reservoir engineers need to be comfortable with the models and be able to challenge the existing models if necessary.
    • Fluids analysis. The fluid model in the simulation model will be generated by the reservoir engineer. Appropriate fluid tests should be performed to correctly characterise the reservoir fluid(s).
    • Petrophysical analysis. A reservoir engineer should be comfortable with the principles of petrophysics and should have an understanding of raw and interpreted log curves. The reservoir engineer should lead the analysis of RFT points.
    • The reservoir engineer should take the lead on certain Special Core Analysis measurements such as relative permeabilities, capillary pressure and wettability.
    • Economic analysis. The engineer will be expected to work closely with the economist and understand and, if necessary, challenge the outputs from the analysis.
    • Reservoir Management - Monitor well and reservoir performance to optimise field and well management with Production Engineers.
  • The lead reservoir engineer should be continually trying to improve knowledge and competencies through training courses, conferences and, of particular importance, self-study. He should also encourage this from his team and share experiences appropriately.
Education & Experience
  • Undergraduate or post-graduate degree in a numerate subject, preferably Engineering, required, or appropriate equivalent
  • Post graduate Petroleum Engineering qualification preferred
  • Professional designation, e.g. CGeol, CEng, desirable
  • Affiliation to professional body e.g. SPE, SPEE, desirable
  • Robust knowledge and understanding of the upstream oil and gas business model
  • Broad knowledge of G+G, petrophysics, and production engineering
  • Detailed knowledge and / or experience of the following:
    • Simulation
    • Well test analysis
    • Nodal analysis
    • Fluids and PVT
    • SCAL
  • Operational, offshore experience would be desirable. In any case an understanding of the offshore environment is essential.
  • Ability to lead a small team to maximise the capabilities of the team members.
  • Ability to work with cross-discipline teams.
  • Ability to budget time and resources, and able to alert management should either the time or costs be trending over budget.
  • Able to balance short term urgent assignments with longer term important assignments
  • Displays honesty, integrity and a strong sense of ethics in all decision and actions, role-models the “values”, and displays a strong personal commitment to upholding the highest standards of HSE
  • Good interpersonal skills and ability to work under pressure and deliver timely results, coupled with individual drive and self starting initiative and the ability to work in a fast paced environment without compromising integrity
  • Personal commitment to organisational and technical excellence
  • Flexibility and learning capacity
