Exploration & Development - KJO

 

Exploration

2D and 3D seismic has been shot within the KJO Area. Many prospects have been identified and Plans are in place to drill exploratory wells.

The recent 3D seismic survey was acquired in 2012 for Hout Field with an OBC technology in order to better image the Fracture Distribution and Compartmentalization as well as the Formations Boundaries of the Hout Field.

The objective of the seismic is to aid exploration efforts in evaluating producing potential in the Jurassic, Triassic, Permian and Devonian stratigraphic sections.

There are plans to drill HPHT deep wells to explore the deeper formations such as Khuff & Pre-Khuff.

Development

Development of the existing fields, especially Khafji, is ongoing. New drilling technologies are being implemented. Development drilling is targeting field areas that have not been adequately drained to this point through longer reach horizontal drilling and horizontal re-entry work-overs.

Engineering

Reservoir Engineering/ Petroleum Engineering for Oil and Gas fields is engaged in discovering better ways to extract hydrocarbons. They are involved in every aspect of field and well operations once the decision is made to drill a well.

Field Development Studies

The various aspects of Reservoir/Petroleum Engineering provide a key element in the action plans for all for all field development efforts. Once a target reservoir has been identified, it is the job of the Reservoir/Petroleum Engineers to create practical and cost-effective solutions to get the Oil and Gas from the reservoirs to the processing and storage facilities.

Drilling

All aspects of the drilling program are carefully designed. Highly deviated and horizontal well technology is used to extract hydrocarbons from the offshore fields.

Completions

A variety of well completions are currently in use in the offshore area. These include gas lift and ESP (Electric Submersible Pumps) wells.

Water Injection

Injection of water (by down-hole dumping) has been used to maintain reservoir pressure in Khafji Field.

Reservoir Simulation

Major reservoir studies have been conducted to evaluate and predict the performance of reservoirs under various scenarios. The results are used to substantiate development plans in an attempt to extract an optimal amount of the reserves. Frequent pressure, fluid property and flow tests ensure valid simulation results.

Wellheads, Flow-lines and Valves

Safety, as well as basic operational requirements, mandates that all components of the flow path from the reservoir to the storage tank be designed, constructed, installed and monitored to ensure production and storage of oil and gas. The installation and replacement of sub-surface safety valves (SSV) continues to protect the environment and personnel in the unlikely event of a surface disaster.

Flow-line Network Modeling and Production Allocation

Extensive modeling of the surface flow-lines is used to allocate Oil and Gas production back to individual wells. Frequent well flow testing and the addition of additional flow metering are used to validate the accuracy of these models. The proper allocation of production helps achieve accurate reservoir simulation results.

Well Testing

A variety of well tests help engineers identify problems and understand the dynamics of well and reservoir performance. These include routine pressure, temperature, flow and fluid property tests.
