Offshore oil & gas production, which involves extracting oil and gas from beneath the sea, is a critical component of the world's energy supply.
It requires the use of increasingly sophisticated technology and ever greater attention to the related environmental impacts.
In order to perform offshore activities, organizations have to contract an offshore drilling expert who has the expertise to build an offshore drilling platform and get an offshore drilling rig over the offshore platform.
Offshore drilling is basically drilling of wells in the sea in shallow or deep water using offshore rigs.
To perform offshore drilling operations, special types of offshore drilling rigs are used depending on the water depth.
These rigs are used to drill oil or gas well in water.
The most common types of drilling rigs are jackup rigs that are used up to 120 meter of water depth.
Similarly, drill ships and semi-submersibles are used for drilling in deeper water depths.
The final phase of offshore operations is the abandonment of wells, the decommissioning and removal of offshore facilities to onshore disposal, and the flushing, cleaning and abandonment of pipelines.
Operated and owned by state-run Saudi Aramco – the Safaniya oil field is the biggest offshore oil field in the world.
The field is believed to contain an estimated total reserve of more than 50 billion barrels.
