The East Spar Project is an offshore gas production development located off the northwest coast of Australia in the Carnarvon Basin. It primarily serves the Greater Gorgon Area and is significant in terms of hydrocarbon extraction and natural gas production. Let's delve into its description and specifications:

Description:

1. Location: The East Spar Field is situated approximately 40 kilometers to the west of Barrow Island in Western Australia. The gas field lies in the Carnarvon Basin, a prolific hydrocarbon province.

2. Ownership and Operatorship: It involves multiple stakeholders, with Chevron being one of the principal operators.

3. Development:

   • The gas production facilities are typically subsea completions tied back to processing facilities.
   • Gas produced in the East Spar Field is transported via subsea pipelines to onshore processing facilities or other offshore structures for processing and export.

4. Installation: The development might involve production platforms, subsea wellheads, manifolds, flowlines, and export pipelines. Subsea intervention technologies are often employed.

Specifications:

1. Field Infrastructure:

   • Subsea Components: Production wells, subsea trees, manifolds.
   • Pipeline Systems: Export pipelines transporting gas from the field to processing facilities.
   • Control Systems: Subsea control umbilicals for remote operation of subsea equipment.
   • Other installations: Riser bases, tie-in structures.

2. Technical Details:

   • Water Depth: The field is located in water depths ranging from 100 to 150 meters.
   • Reservoir Characteristics: The reservoirs targeted are generally mid-to-late Jurassic sandstones with good porosity and permeability conducive to gas production.
   • Production Capacity: Specific production rates can vary depending on the number of wells and their productivity, but the East Spar Field contributes significantly to the regional gas output.

3. Operational Aspects:

   • Flow Assurance: Use of flow assurance techniques to prevent issues like hydrate formation, wax deposition, etc.
   • Remote Monitoring and Control: Advanced subsea technologies allow for the remote monitoring and control of well operations.
   • Safety and Environmental Management: Adherence to stringent safety and environmental regulations.

4. Export Facilities:

   • Gas is exported primarily via subsea pipelines to onshore gas processing facilities, or to facilities on Barrow Island associated with larger projects like the Gorgon LNG Plant.
   • The integration with other fields and facilities in the region is a strategic approach for optimizing resource development.

Transport and Refining:

1. Onshore Facilities: The gas extracted is processed and transported to onshore facilities where it undergoes separation, treatment, and liquefaction for LNG export.
2. Export Pipelines: Subsea pipelines connect the offshore field to processing terminals, ensuring efficient transportation of extracted hydrocarbons.

Additional Notes:

• The East Spar development should not be viewed in isolation but rather as part of the broader network of production facilities in the region, contributing to Australia's significant LNG export capabilities.
• Continuous investment in technology and infrastructure ensures the East Spar Field remains productive and efficient within the operational and environmental safety standards.

By focusing on these core aspects, the East Spar Field exemplifies modern offshore gas field development and production practices in Australia’s prolific Carnarvon Basin.
