Petroka has excellent people and excellent systems – which forms the foundation of solid advice to our clients.
Successful field development planning in the early project phases is essential to both identifying the potential project value and then realising that potential value. Best in class field development planning provides both a bridge between the identify/assess and select phases of the project development and a fully integrated approach including subsurface disciplines, wells and production technology specialisms, surface facilities engineers and also operations. In many jurisdictions a Field Development Plan is required to provide the regulator with sufficient opportunity and information to gain an understanding of the field and its conceptual development.
Petroka are experts at the preparation of Field Development Plans. We support our clients with either specialist expertise in defined areas to supplement the client team or a fully integrated team of oil and gas professionals work closely with the client to prepare the development plan. Our approach, techniques and tools are proven and best-in-class.
Developing a successful Field Development Plan involves aspects such as:
Data collection, Scope Definition and setting the boundaries of development planning
Interpretation of 2D/3D seismic data and estimation of reserves, geological modelling and reservoir simulation
Development of production profiles and associated production engineering and EOR strategy
Opportunity Framing workshop to identify development opportunities
Front end study with an initial Field Layout Plan with well placement planning, surface facilities layout, export infrastructure and logistics considerations
Development of Risk Register
Performance of Conceptual Engineering
Assuring that the planning and field development plan is in line with country Petroleum Policy
Involving Stakeholders in high level project implementation planning and opportunity framing
Developing a Project Execution Plan including Contracting Strategy
Preparation of Development Schedule
Performing CAPEX, OPEX and Economics

Our clients are small independent oil companies, medium sized and national oil companies. Our multi-disciplinary teams of experts provide complete field implementation planning for offshore and onshore developments, with an emphasis on an integrated client-consultant approach to development engineering.
Petroka’s expertise in performing Conceptual Engineering is unprecedented. Our approach and techniques are proven and are based on years of refinement. We are flexible to fully take the lead or to work in an integrated team with our clients.
Oil and gas developments have many complex and inter-related challenges including flow assurance (e.g. wax, hydrates), remoteness, environmental sensitivity, deep water and logistics. No matter what the challenge is Petroka will always be able to mobilize the right resources to derive an optimal techno-economic solution for our clients’ developments.
We have offshore and onshore experience from the North Sea, Europe, Middle East and Africa. Our multi-disciplinary teams of experts work in integrated teams to develop the optimum Conceptual Design for your oil or gas field.
This phase of your project is our opportunity for innovation. This is when the cost of change is small – so we explore smart developments, new oil and gas technologies and study options and alternatives, before selecting the best concept.
We typically develop a base case concept, on which we develop optional concepts and present these to our client in a conceptual selection matrix. We develop criteria for concept selection and initiate the screening process.
Petroka’s multi-disciplinary team of specialist engineers and consultants will during this phase study facilities options, perform process simulations, flow-assurance, develop the digital oil field strategy, and perform all the associated engineering to support the successful delivery of an economic and technically optimal development concept. This empowers our client to progress their project into the Front End Engineering Design phase.
The Digital Oil Field strategy will also be developed at this stage: Petroka’s-DoF aims to provide enhanced communication solutions for remote monitoring and control, directing the correct amount of data to the correct people, ensuring rapid and informed decisions.
In parallel to the technology and engineering development; project controls will be prepared, e.g. HSE screening, Risk assessment, Development schedule, Equipment listing, CAPEX, OPEX and Economics.
Petroka has great people, great systems and the expertise to deliver best-in-class Conceptual Engineering Studies.
Deliverables from our Conceptual Engineering consultancy services are:
Conceptual engineering report: typically includes development engineering; conceptual selection; technology review; facilities definition based on process simulation and flow-assurance, cost estimation, project controls; Risks, HSE, Schedule; CAPEX and OPEX estimates and Economics
FEED Basis of Design
FEED Scope of Work
The above is our standard approach. However clients and developments are different – and often require a bespoke approach dependent on different drivers.
We are experts at conducting conceptual engineering for our clients. Our Energy Consultancy Services provide you with advice on the best strategy and structure for the development engineering phase of your project. In addition we have great experience in supporting our clients with contracting and tendering.
During the different phases of development engineering planning we continue to refine the Development Schedule, the CAPEX, the OPEX and the Economics.
Performing these crucial tasks requires significant experience and great understanding of the key drivers behind schedule, work breakdown structure (WBS) planning and oil and gas life cycle costs and economics. The team here at Petroka have that experience – backed by state-of-the-art software, tools and databases.
We make use of commercial software, in-house software and maintain data bases in order to drive the best oil and gas life cycle cost (LCC) estimates for production. It’s all focused on optimising your energy project.
The level 1 activities in a development schedule typically include:
Field development approval
Geotechnical survey / Geophysical survey
Permits and EIA
Float / contingency
Schedule and CAPEX estimates for different regions require special attention to subjects such as drilling, logistical constraints, national price index, risks, decision points associated with peer review, benchmarking, uncertainties and sensitivities and algorithm adjustments to take account for special conditions.
OPEX estimation approaches can be adjusted to client requirements and financial parameters. We typically make sure that the delivery of OPEX estimates can be used going forward during production-operation. OPEX estimates include chemicals, fuel, logistics, operator staff, wells, pipelines, processing facilities, power generation operations and maintenance activities, etc.
We typically make use of Net Present Value (NPV) for economic evaluation and have a specially adapted model that can easily be customized to your requirements. We provide recommendations on financial parameters to oilfield NPV analysis for your review and approval. We typically recommend that Sensitivity Studies are performed for various NPV oil price scenarios.
Petroka recommends to apply Value Engineering methodology during the concept selection phase and again during detailed design process to optimise the selected engineering solution.
During the early phases of projects, key issues and difficulties arise around a vast number of conflicting pressures regarding functional analysis, engineering, operations, cost, safety, schedule, reliability, environmental issues, etc. Value Engineering assists in managing and optimising a project solution, taking into account these and many other project related elements.
Our project teams have proven abilities in interface management and the facilitation of workshops. Collaboration and integration is key to ensure that project suggestion counter-arguments are dealt with immediately by subject matter experts, saving time and money. Our recommendations are always based on demonstrable justification. Value Engineering workshops are hosted at an early stage of the project phase with the objective of stimulating creative thinking – the ‘blue-sky’ approach. Our value engineering workshops address:
The initial functional design and value engineering workshops make use of a guided process to lead the team through the workshops with the objective of attaining optimum evaluation for your energy project. At Petroka the benefit of value engineering comes from a proven methodology, experienced engineers and the combination of workshops and offline desktop analysis.By spending a relatively short amount of time on value engineering, most conceivable concepts will have been considered and there will be an audit trail demonstrating why certain options were screened out – and how we arrived at the optimum solution.
