0. Introduction to the HRA report
The Health Risk Assessment (HRA) report is used by PDO to process and store health related information.
The report starts with a description of the scope of the HRA and the persons involved in sections 1 and 2.
The remedial actions from the HRA are presented in report section 3, and are sorted by priority. Section 4
provides information from the detailed appraisals. The focus here is on High and Medium RAM rated risks.
Section 5 lists the status of the Low RAM rated risks that were reviewed during the HRA. Section 6 provides
an overview of generally applicable controls and recovery measures. The report concludes with definitions
and a diagram of the RAM risk matrix in appendices 1 and 2. Appendix 3 contains an overview of the
detailed risk appraisals and their page numbers.
1. HRA Scope
The Saih Rawl and Barik fields are located in central Oman (Qarn Alam). The SRS area is an integral part of the Saih Rawl field. The SRS area is located approximately 15 km from the Saih Rawl Central Processing Plant (SR-CPP) and the Barik Gathering Station (BGS) is located approximately 40 km southwest of Saih Rawl. There is little local population, with only Beduine settlements scattered sparsely around the area surround-ing. The area is a desert plain, comprising alluvial gravel fans arising from several wadis. Figure 1 illustrates the SRS station interfaces with the SRS wells and other facilities.
Figure 1: SRS Station Interfaces with the SRS Wells and Other Facilities
The main objectives of the SRS station are to:
Receive well fluids from the SRS wells.
Carry out a single stage separation to separate the well fluids into gas,
Condensate and produced water.
Export the separated gas to the Saih Rawl Central Processing Plant (SR-CPP)
for further processing via the 16” pipeline.
Send the separated condensate to the 14” Barik – SR-CPP condensate

Pipeline via the 4” pipeline.
Dispose of the produced water by injecting the produced water into the injection
Wells via the 4” GRE pipeline.
The SRS station includes the following main facilities:
Inlet manifold.
Three phase separator.
Export pipelines.
Utilities Figure 2 illustrates the BGS interface with the flow lines from Barik wells and plants.
Figure 2: BGS Interfaces with the Gas Gathering System and Plants
The main objectives of the BGS station are to:
Gathered Well fluids and separated into gas, condensate and water.
Conditioned and transported the separated gas to SR-CPP via the 32” gas pipeline.
Transport the separated condensate to SR-CPP via a separate 14” pipeline parallel to the gas
pipeline.
Transferred Produced water via a separate pipeline for further treatment and disposal. Produced water is preferably sent to the Barik Central Gathering Station (BCGS) and then to Saih Rawl Oil Station (north side).
The BGS comprises the following:
Inlet Manifolds.
Inlet Separation and Depletion Compression (Unit 10).
Exporting Facilities.

Appendix 1: Definitions
Acute Health Effect Health Effect that occurs immediately or a short time (seconds to hours) following exposure, such as heat stroke, chemical burns and asphyxiation. Agent See Hazard ALARP - As Low As Reasonably Applicable The point at which the cost (in time, money and effort) of further Risk reduction is grossly disproportionate to the Risk reduction achieved. Barrier A Risk Control or a Recovery Measure. Barriers provide the means of preventing an Event or Incident, or of mitigating the Consequences. A Barrier can be an item of equipment or a human intervention, and can also be a Control on an Escalation Factor. Chronic Health Effect Health Effect that occurs gradually over a long period of time (months or years), generally following repeated and prolonged exposure. In specific cases a short term exposure may result in a chronic health effect. Consequence An Effect on people, assets, the environment or reputation as a result of a Hazard being released. Control A means of preventing an Incident. Controls can be engineering, procedural or behavioral. Critical Activity An activity necessary for the development, implementation or maintenance of a Barrier established for managing Hazards with RAM red Risks. Effect The Consequence of the release of a Hazard. Escalation Factor A situation, condition or circumstance that may lead to the partial or full failure of a Barrier. Event An Incident that occurs when a Hazard is released. Exposure Limit The airborne concentration of chemical agents and levels of physical agents to which nearly all workers may be repeatedly exposed day after day without adverse Effect. Exposure Rating The chance of over-exposure to a health hazard when compared against agreed control standards. The exposure rating is evaluated as Very Low, Low, Medium or High. Hazard An agent with the potential to cause harm to people, damage to Assets, or an Impact on the environment or reputation. Health Hazard A factor of a physical, chemical, biological, ergonomic or psychological nature with the potential to cause harm to the health of people.

HRA - Health Risk Assessment A process of identifying, evaluating, controlling and managing Health Risks, associated with work to prevent acute and chronic health Effects. Incident An unplanned Event or chain of Events that has, or could have, resulted in injury or illness or damage to Assets, the environment or reputation. Likelihood The probability that a specified Consequence will happen. OEL – Occupational Exposure Limit The airborne concentration of chemical agents and levels of physical agents to which nearly all workers may be repeatedly exposed day after day without adverse effect. RAM - Risk Assessment Matrix A tool used to assess the Consequences and Risks of Hazards to HSSE. The results are referred to as a RAM Severity rating and a RAM Risk rating. Recovery Measure A Barrier that reduces the Consequences of the release of a Hazard as a result of an Incident. Recovery Measures can be engineering, procedural or behavioral measures. Remedial Action Plan RAP - A Plan to implement corrective action items. Risk The combination of the Consequence of a specific Hazard being released and the Likelihood of it happening. Risk Assessment The process of identifying the Consequences of the Worst Case Credible Scenario arising from the release of a Hazard, and estimating the Likelihood of that scenario. Severity A level of Consequence on the RAM on a scale of 0 to 5. TBD To be determined.
