    1 INTRODUCTION This document presents a Study Plan to undertake the field development facility studies (Surface Facilities and Subsea) for YYY Development. The principles of the facility FE work will follow the following route map:

    However, the field development requires the integration of subsurface, drilling, operations, commercial and facilities in an overall development plan e.g. as typical below:

    1.1 FACILITY WORK PLAN SUMMARY This document presents an example front end plan to mature a prospect through Option Selection, through to the FEASIBILITY gate and readiness to commence FEED and Tendering. The document describes the following main steps:

    1. Development Team Set-up & mobilization 2. Project Charter or Statement of Requirements (SOR) 3. Preliminary Functional Requirements 4. Feasibility Studies & Brainstorms (Demonstrate Technical & Economic Feasible

    Schemes (Including riser performance vs hull form, flow assurance, field architecture, reservoir depletion requirements, oil and gas disposition options, etc.) 5. Development Option Screening 6. Final Option Selection 7. Feasibility Deliverables (FEASIBILITY) Facilities (Surface and Subsea), G&G and

    Subsurface, Operations and Drilling 8. Value Engineering (VE) 9. Contracting Strategy 10. FEED Tender ITT Data 11. FE Study and Team Administration and Planning

    2 WORKPLAN

    2.1 STUDY ACTIVITIES Initial study work activities focus on technical requirements and feasibility of the key building blocks reservoir and well depletion requirements, field architecture, flow assurance, riser performance vs hull selection options, oil and gas export options etc.

    STUDY TEAM SET-UP

    Establish framework for Study Team to work efficiently and effectively: Non-disclosure agreement Preliminary Study Plan and approach Document Control procedure and file structure Team Roles and Organization Reporting Charter (SOR) & Preliminary Functional Basis Brainstorm alignment sessions Preliminary Schedule Milestones Equipment Tagging procedure Team Office Facilities, Communications

    A provisional suggested FE team would be organized as follows:

    DW FEASIBILITY & OPTION SELECTION Rev C Jan 2 2015

    A Preliminary Functional Basis for commencement of studies would include the following items. This functional basis will be developed thru several working sessions and data compilation.

    2.2 FEASIBILITY STUDIES This stage needs to determine technically feasible schemes, and an understanding of the limitations and definition of key building blocks.

    3 OPTION SCREENING (QUALITATIVE SELECTION PHASE 1) Once an understanding is established of feasible building blocks and credible schemes, then the option selection process can be commenced. Key elements are summarized as follows, and further defined in DRL Option Screening Methodology (Phase 1 - Qualitative & Phase 2 - Quantitative).Procedures see attached.

    Establish all the building blocks and brainstorm all credible options for base development, futures and potential 3rd parties. Requires involvement of all leading disciplines and management:

    Agree screening selection parameters Prepare preliminary Field Schematics and descriptions of main options and

    associated preliminary benchmark cost and schedules

    DW FEASIBILITY & OPTION SELECTION Rev C Jan 2 2015

    Screening Workshop to select leading options based on :

    i. Relative Costing, ii. Schedule iii. Recoverable Reserves efficiency iv. Technical Risk, v. Integration and Installation Risk vi. Operability & Reliability, vii. Flexibility for futures
