1 Introduction1.1 Scope

This Code of Practice defines the Strategies and Controls that need to be implemented in PDO to ensure safe and effective Operation of Surface Product Flow Assets.

Effective Operations hinges on three main themes: Process, People and Documentation. The integrity of the plant is captured in CP-114 - Maintenance & Integrity Management Code of Practice.

The process is the operation of the integrated product flow assets and associated safeguarding systems within defined operating envelopes. Supporting the process is the need for the correct organisational structure with competent people who are capable of performing their job roles effectively and who are fully aware of their accountabilities, authorities and responsibilities. In addition, these people need effective and current documentation to assist them to carry out operational activities in a controlled, consistent and structured manner.

This Code of Practice makes reference to the Operations Excellence in Production Standard and is aligned to the process. The documentation required to operate the Surface Production Facilities in line with the above standard will be sourced from PDO and LiveLink or the Shell web.

Each discipline will have a standard which will list decisions and deliverables that it will contribute to the Operations Phase and the authority level required to sign that off. This will be in accordance with the Discipline Controls and Assurance Framework (DCAF) application.

1.2 ObjectivesThe purpose of this Code of Practice is to specify the processes and controls necessary to ensure effective Operation Management of all installed assets over their Lifecycle. Effective Operation management shall demonstrate compliance with relevant statutory requirements, PDO Standards and Procedures, and verification requirements.

1.3 ApplicabilityThis Code of Practice is principally applicable to:

- Area Operations Teams;

Operations Managers.

Delivery Team Leaders.

Production Coordinators.

Production Supervisors.

- Production Strategy & Support.

- Programming.

- Integrated Activity Planning.

- Corporate Discipline Functional Heads (CDFH) and Corporate Discipline Focal Points (CDFP)

The secondary target audience are certain members of the Production Support teams and Service Providers, the Petroleum Engineering and Field Engineering teams.

2 Operations Management of Surface Product Flow Assets

2.1 PL-11 Asset Integrity and Disposal PolicyIt is PDO policy that:

Facilities and wells shall be designed, operated and maintained in a manner that safeguards their integrity and ensures their planned availability throughout their life-cycle;

Redundant assets shall be written off and removed where appropriate and the environment restored to, or as reasonably practicable to, it’s original state within an agreed time-frame;

The impact of this policy is that our assets will be operated as intended, within their design envelope, and will be disposed of with due regard to environmental and economic considerations.

The objective of this policy is to:

Ensure that physical assets have design integrity that is based on fit for purpose performance standards;

The designed technical integrity is maintained throughout the Lifecycle up to and including abandonment;

Redundant assets are approved for write-off, disposed of as appropriate and financial records updated accordingly;

This CoP has been developed to provide a framework to ensure adherence to the above policy.

2.2 Corporate Asset Integrity VisionThe PDO Asset Integrity Vision is:-

“Our assets are safe and we know it”For Operations this means that through correct operation and with competent trained personnel, and by following clear rules and procedures we will ensure that our assets are operated safely and produce at design capacities to meet Production Targets.

2.3 The Operations Vision: “Our vision is that by 2020 PDO will be Oman’s most competitive full-life operator of choice, delivering our production safely, at the highest technical capacity and lowest unit cost.”

2.4 The Operations StrategyThe Operations Strategy (delivering the Vision), contains six high-level themes and objectives:

1. People: We will invest in building a fully capable workforce with a strong talent pipeline.

2. Production: We will produce at the highest possible technical capacity.

3. Efficiency: We will achieve best in class process and cost efficiency.

4. Safety: We will strive to achieve Goal Zero in Operations, including no major process safety incidents.




5. Learning organisation: We will routinely measure ourselves against the best and learn from them.

6. Partners: We will be supported by highly effective and efficient delivery from the wider PDO organization.

The proposed program is extensive, covering all aspects of the Operations value stream, from capability building to performance management; from embedding Lean to Supply Chain Management improvements.

2.5 Operations Management ObjectivesThe objectives of Operations Management in PDO are to:

Safeguard and demonstrate operating and technical integrity of the assets;

Optimise resources and costs involved with operating activities;

3.3 Field OperationsProcesses and procedures shall be put in place or adopted that shall ensure safe and effective operation of the Asset.

Surface Production Operations are responsible for the overall coordination of the safe execution of daily operations, major maintenance, minor projects or well interventions. Ensuring work sites are safely managed in terms of HSSE and operating integrity is key to the success of field operations.

Operating Integrity is the “paying attention process” without which efficient safe field operations will never be achieved. Operators must understand and know their operating limits and stay within them at all times. The assignment of a system owner for each segment of the integrated production system, with responsibility for operating integrity in their segment, is essential.

Production operations shall be aligned with Blade 24 of the Operational Excellence Standard – Field Operations.

3.3.1 Asset Reference PlanThe Asset Reference Plan (ARP) is the principal management tool by which Assets are effectively and efficiently managed throughout their life. The ARP shall be routinely updated, with awareness of the key business drivers that will optimise output, and maximising the best use and value of limited resources locally and globally in order to maximise the value of the Asset.

Reference: Asset Reference Planning Guide

3.3.2 Statement of Fitness (SoF)Throughout the Operations Phase a Statement of Fitness shall be required as assurance that the facility / plant / equipment is safe to operate. The SoF shall be required to be submitted before;

3.3.13Crude Oil Export OperationsAll crude production from the interior is transported by pipeline to the Tank Storage and Marine Terminal facility at Mina Al Fahal.

NOTE: The proximity of the terminal to the shore and office complex means anyone can observe the day to day vessel mooring and cargo handling operations. Such scrutiny together with tight environmental legislation further emphasises the need for marine personnel to carry out their duties to the highest possible standard.

The tank storage facility will provide an interface between the interior and the marine terminal and allow for continuous production from the fields and settlement of the inventory prior to offloading to the tankers. Operations at the tank storage facility (tank farm) shall be in accordance with the following procedures:


PR-1076 - Isolation of Process Equipment ;

The Marine Terminal, which includes tanker berthing and loading, shall be in accordance with PR-1563 - MAF Marine Terminal Marine Procedures.

3.4 Integrated Activity Planning and Shutdown ManagementIntegrated Activity Planning (IAP) is an important optimisation process that is an integral part of managing production and activities. It is the integration and rationalisation of
























plans provided by different functions or departments to achieve minimum scheduled deferment, optimum efficient use of resources, avoid clashes and ensure attainment of company objectives.

The IAP and Shutdown forums with its associated deliverables (agreed plans) are key enablers for the asset operator to control their assets.

In PDO, IAP shall be primarily used to:

Maximise availability of production facilities;

Align and optimise Gas demand versus available capacity;

Optimise resource deployment;

Reduce and control costs;

Provide a basis for delivering an accurate production forecast;

Reduce HSE exposure;

Serve as a common reference for controlling the Execution phase (stability and PTW);

Provide a means to analyse the Planning / Scheduling and Execution phases;

Alignment with the 5 year Program Build (yearly input as well as inclusion of new activities / projects);

Establish the High level Shutdown window overview and form the starting point for detailed shutdown planning process;

The IAP Process includes integration of all activities that impact field operations (including all production impacting activities) and / or make use of shared critical resources within the 14d, 90d and 2 year windows. The Permit To Work process uses area 14 day plans as the reference for all plannable work.

The Shutdown Management Process is a process that stipulates in detail how Shutdowns are prepared, executed and reviewed. This is in addition to the routine cyclic IAP process. These shutdowns are often the ultimate form of integration of many activities with increased associated HSE and business risks. Therefore this is described separately in a dedicated procedure (PR-1721 - Shutdown Management). Much emphasis is on identifying and mitigating cross functional HSE risks.

Typical examples of integration are; carrying out well test during shutdowns; combining several project tie-ins into a single SD date; integration of all Operations and Engineering shutdown requirements; and aligning inter-directorate impacting activities such as MOL or Power outages.

IAP and associated processes are covered in more detail by

CP-156 - Integrated Activity Planning ;

PR-1721 - Shutdown Management ;

Blade 9 – Integrated Activity Planning ;

EP 2006-5471 Integrated Activity Planning Process Guide ;

EP 2006-5081 Shutdown Management Process Guide ;

3.5 Programming and Hydrocarbon AllocationProduction Programming and hydrocarbon allocation manages the short and medium term production, injection and optimisation and then allocates these fluids back to wells and reservoirs.

Specifically Programming involves:



http://epgraphics.europe.shell.com/restricted/report/2006/ep2006-5081/ep2006-5081.pdf







Performing exception based surveillance, monitoring and evaluation of wells and facilities. Trouble shooting any production anomalies;

Meeting sales commitments (rate and quality), injection targets and to optimise short-term cash flow. This involves the near 'real-time' to short-term scheduling, deferment reduction and optimisation of production and injection rates with due consideration for well and reservoir management, technical integrity and HSSE issues;

Creating the short-term (ST) production plan (IPP) in order to meet short-term sales commitments, whilst meeting sales commitments based on the medium-term (MT) forecast. Taking into consideration integrated production planning (scheduled deferment) new oil, constraints and unscheduled deferment as well as NFA production;

Manage the planned vs. actual reporting to the HCA / Forecasting team;

Requesting and evaluating well tests, samples and ad hoc data for trouble shooting;

Ensure that data of the required quality is recorded, so that it can be made available to functions that need it;

Ensuring that there is a closed improvement loop for production operations by managing activities to ensure that smart field loops are completed / closed;

Monitoring metering performance for product flow measurements and managing data / meter corrections via the field operations / metering teams;

Provides a smooth interface between Production Operations and other departments, especially WRFM teams, engineering and well engineering e.g. leading and co-ordinating collaboration centres for near real-time optimisation;

Production programming will be aligned with Blade 23 of the Operational Excellence Standard - Programming.

Programming activities including deferment administration, well testing will be managed in accordance with:

PR-1080 - Well Testing, Scheduling, Sampling and Validation ;

PR-1096 - Sampling of Oilfield Liquids and Gases Procedure ;

GU-620 Deferment and Reporting Guidelines ;

Shell Programming Process Guide EP2009-9015

EP 2007-9017 Deferment Administration Manual ;

Programming also has a strong link the with Blade 27 Well and Reservoir and Facility Management process of the OE Standard

Forecasting will be managed using the following documents and is aligned with Blade 26 Forecasting of the OE Standard

CP-153 – Production Forecasting – CoP;

EP 2008-1913 Production Forecasting Process Guide ;.

Metering will be managed by the following documents:

PR-1304 - Product Flow Measurement ;

PR-1099 - Metering Flow Factor Update Procedure ;

PR-1293 - MOL Metering System Verification Procedure ;
