Feasebility Studies

In the oil and gas sector, a Feasibility Study (FS) assesses the technical, economic, and operational viability of a project before significant capital is committed. It evaluates various engineering design options to filter out non-viable alternatives and ensure the proposed infrastructure is both safe and profitable

Key Components of an Engineering Feasibility Study

Engineering design at the feasibility stage establishes a solid foundation of data-driven decisions. It is broken down into several interconnected layers :

  • Technical Feasibility: Validates whether the technology exists, selects the production processes, and identifies long-lead equipment requirements.
  • Economic & Financial Analysis: Calculates rough investment costs and evaluates profitability metrics such as Net Present Value (NPV), Internal Rate of Return (IRR), and Return on Investment (ROI) to secure stakeholder funding.
  • Site & Operational Viability: Assesses geographic conditions, required maintenance, integration with existing systems, and overall ease of operation.
  • Safety and Environmental Impact: Conducts initial risk assessments and surveys to ensure regulatory compliance and harmony with regional development programs.

 Engineering Workflow Progression

A feasibility study is the vital precursor to the actual engineering execution phases:

  1. Concept & Feasibility Studies (FS): Acts as an early reality check. Engineers determine the best solutions based on cost and regulatory standards.
  2. Front End Engineering Design (FEED): Once a project is proven viable, FEED refines the scope and technical requirements into basic engineering. It sets the baseline for competitive tenders and EPC (Engineering, Procurement, and Construction) bidding.
  3. Detail Engineering Design (DED): The final phase where exact specifications, blueprints, and equipment layouts are finalized for the actual construction phase.

Conceptual Design

in the oil and gas sector is the initial phase of project development. It defines the project’s core vision, assesses technical feasibility, and establishes high-level costs and schedules. This critical early stage prevents costly modifications by filtering out unviable ideas before heavy capital investment.

Core Objectives

Feasibility Assessment: Determines whether a proposed project or field development makes sense from technical, economic, and safety standpoints.

Concept Screening: Evaluates multiple design alternatives (e.g., onshore vs. offshore facilities, different processing methods) to select the most profitable option.

Budget & Schedule Estimation: Provides rough-order-of-magnitude (ROM) cost estimates (often Class 5 or Class 4) to guide management decisions.

Key Activities & Deliverables Conceptual engineering translates a business idea into technical requirements:

Design Basis: Establishes the parameters, capacity limits, and operating environment of the facility.

Process Flow Diagrams (PFDs): Creates high-level block diagrams outlining fluid composition, flow rates, and overall operational principles.

Site Evaluation: Analyzes meteorological data, geographical challenges, and logistical requirements.

Technology Screening: Identifies potential proprietary technologies or licensors required for specialized processes (e.g., LNG liquefaction or heavy oil upgrading).

Front End Engineering Design (FEED)

Front End Engineering Design (FEED) is a critical planning phase in the oil and gas industry that bridges the initial concept and the detailed engineering stage. It translates feasibility studies into actionable technical specifications and high-level cost estimates, creating the foundation for project execution and the Engineering, Procurement, and Construction (EPC) phase.

Why FEED is Crucial in Oil & Gas

  • Risk Mitigation: It identifies technical, environmental, and financial hurdles early, preventing costly mistakes during actual construction.
  • Cost Estimation: It produces a project budget and procurement estimates that typically have an accuracy margin of ± 15% to ± 25%.
  • Basis for Bidding: The resulting “FEED Package” serves as the core documentation used to solicit bids from EPC contractors.

Key Deliverables & Activities

During this phase, multi-disciplinary teams (process, mechanical, piping, electrical, and safety) develop several core documents:

  • Basis of Design (BOD): Outlines the fundamental parameters, standards, and operating conditions.
  • Process Flow Diagrams (PFD) & Piping and Instrumentation Diagrams (P&ID): Map out the operational flow and equipment connections.
  • Safety & Hazard Studies: Includes HAZOP (Hazard and Operability Study) to ensure plant safety.
  • Equipment Specifications: High-level datasheets for major long-lead items like pumps, compressors, and vessels.

How it Fits the Project Lifecycle

In capital oil and gas projects, engineering generally follows a phased approach:

  1. Conceptual Design / Feasibility Study: Assessing if the idea is commercially and technically viable.
  2. Pre-FEED: Optional early studies to flesh out specific options before committing to full FEED.
  3. FEED: The heavy lifting of basic engineering, resulting in a finalized project scope.
  4. Detailed Engineering Design (DED): The final, granular engineering phase for procurement and construction.
  5. EPC Execution: The actual building, testing, and commissioning of the facility.

Understanding FEED is highly valuable if you are navigating project management or bidding processes.

Detail Engineering Design

Detail Engineering Design (DED) in an oil and gas company is the final, comprehensive engineering phase that translates the conceptual Front-End Engineering Design (FEED) into exact technical specifications, drawings, and calculations. It prepares all necessary documentation required for equipment procurement, facility construction, and project execution.

Core Objectives

  • Constructability & Safety: Validates that the theoretical designs from FEED can be safely built, maintained, and operated in the real world.
  • Procurement Readiness: Produces the technical datasheets and material requirements required to order long-lead items and heavy equipment.
  • Risk Mitigation: Minimizes construction errors, costly rework, and delays during the actual fabrication or construction phase.

Key Deliverables & Activities

  • Detailed Technical Drawings: Generates Issued-For-Construction (IFC) drawings, 3D models, piping and instrumentation diagrams (P&IDs), and fabrication schematics.
  • Engineering Calculations: Performs rigorous stress analysis, fluid dynamic simulations, and structural load validation.
  • Bill of Quantities (BoQ): Compiles complete material take-offs and equipment specifications needed for contractor bidding and accurate cost budgeting.
  • Vendor Document Review: Evaluates and approves the technical documentation and fabrication drawings submitted by equipment suppliers.

Primary Disciplines Involved

Detail Engineering Design requires close multi-disciplinary collaboration across several core fields :

  • Process Engineering: Finalizes heat and material balances (HMB), sizes equipment (vessels, heat exchangers, pumps), and develops complex P&IDs.
  • Mechanical & Piping Engineering: Designs pressure vessels, tanks, rotating equipment, and runs pipe stress analyses.
  • Civil & Structural Engineering: Designs foundations, pipe racks, steel structures, and offshore topside modules.
  • Electrical & Instrumentation: Details electrical distribution, substations, control systems, and safety shutdown systems.

Understanding Detail Engineering Design is critical for executing projects—ranging from onshore pipelines to offshore flowlines.

Revese Engineering

In the oil and gas sector, reverse engineering is the process of deconstructing undocumented, legacy, or proprietary equipment to recreate accurate digital twins and fabrication drawings. It enables companies to bypass obsolete supply chains, manufacture spare parts, and perform structural or pipe stress analyses on existing facilities.

The Core Process

The reverse engineering workflow in oil and gas engineering generally follows a systematic 5-step deconstruction method:

  1. Field Data Acquisition: Technicians perform non-destructive testing (NDT) and dimensional surveys. This often includes advanced 3D laser scanning to capture precise spatial data of pipes, pressure vessels, and structural steel.
  2. Decomposition: Equipment is disassembled to measure internal mechanics and materials. Traditional precision tools like calipers, micrometers, and Coordinate Measuring Machines (CMM) are used alongside point-cloud scan data.
  3. Condition & Material Analysis: Engineers analyze the chemical composition and mechanical properties of the original components to understand refractory needs and metallurgy.
  4. Reconstruction & CAD Modeling: Captured data is imported into specialized software (e.g., Geomagic Design X, AutoCAD) to build 3D CAD models and 2D blueprints.
  5. Simulation & Redesign: The recreated designs are validated using Finite Element Analysis (FEA) and Pipe Stress Analysis. This ensures compliance with industry standards like ASME B31.4 and API RP 14E.

Common Applications

  • Spare Part Replication: When original equipment manufacturers (OEMs) are no longer in business or have inflated lead times, reverse engineering facilitates local manufacturing of impellers, valves, and pump housings.
  • Fitness-for-Service (FFS): Assessing heavily corroded or damaged vessels (e.g., +70-meter columns) to determine safe operating limits and design structural repairs.
  • As-Built Documentation: Generating up-to-date As-Built drawings for aging platforms and refineries where original blueprints have been lost or modified over time.
  • Debottlenecking & Optimization: Modifying existing pipeline network models to optimize flow rates and prevent excessive pressure drops.

Design Review

An Engineering Design Review in the oil and gas industry is a comprehensive, multidisciplinary evaluation of project documentation to ensure safety, reliability, and cost-effectiveness. It verifies compliance with industry standards (e.g., API, ASME, OSHA) and prevents costly rework before construction.

Key Stages of Design Review

Design reviews align with the standard project execution phases, occurring at critical gates to ensure engineering maturity:

  • Conceptual Design: Evaluates overall project feasibility, sizing, and concept selection.
  • Front-End Engineering Design (FEED): Assesses the technical deliverables (e.g., P&IDs, 3D models) before detailed engineering begins to freeze the project scope.
  • Detailed Design: Verifies exact technical drawings, material specifications, and construction workflows.
  • 30%, 60%, and 90% Reviews: Discipline-specific reviews ensuring engineering development is on track and major features are defined before advancing to the build phase.

Core Areas Evaluated

  • Process Safety: Validates RAGAGEP (Recognized and Generally Accepted Good Engineering Practices), critical relief/flare systems, and pressure vessel integrity.
  • Operability & Ergonomics: Assesses Human Factors Engineering (HFE) standards so the facility is easily accessible, safe, and maintainable by operators.
  • Asset Integrity: Reviews gas system piping and structural analysis to ensure components can withstand harsh operating environments.

Essential Review Activities

  1. Multidisciplinary Workshops: Involves process, mechanical, safety, and project leads to discuss design criteria and address stakeholder concerns.
  2. Document Appraisal: Checks calculations, P&IDs, equipment specifications, and surveys for discrepancies or gaps.
  3. Safety Analysis: Uses Hazard and Operability Studies (HAZOP) and oil and gas design guidelines to eliminate risk
