BP awarded Petrofac an $800 million contract for the second stage of development at the Khazzan natural gas field in Oman, Reuters reports.

The company will be conducing work on the central processing facility at the field with the goal of increasing output from the field by 500 million cubic feet per day (mcf/d) to 1,500 mcf/d, according to the Times of Oman.

Petrofac also conducted work on the first phase of the project, Reuters notes.

BP expects around 300 wells to be drilled in the natural gas field to recover approximately 10.5 trillion cubic feet (tcf) of natural gas, according to Reuters.

In September, BP announced that it had begun to draw gas from the field.

The full development of the field is expected to cost $16 billion, the Financial Times reported in September, and the field’s output should satisfy approximately one-third of Oman’s national demand.

It is located in Block 61. The project is managed by BP and Oman Oil Company.

Petrofac is a British oil-services company.
