Karat Deep Gas Appraisal
Appraisal of a deep, high-pressure sour gas structure — three wells below 5,200 metres, extended well testing and a development concept study for a resource that may exceed 4 trillion cubic feet.

Al Nakhil Field Development, Phase II
The second phase of an onshore oil development: 38 new wells, a second processing train and a produced-water reinjection scheme that lifts the field from 26,000 to 45,000 barrels a day.

About the asset
Al Nakhil was discovered in 2009 and brought on stream in 2014 with a single 26,000 barrel-a-day train. Ten years of production history sharpened the reservoir model considerably: the original development left the northern flank under-drained, and pressure support across the main compartment turned out to be weaker than the appraisal wells had suggested.
Phase II answers both problems at once. Twenty-four infill producers target the northern flank and the attic oil left above the original well spacing, while fourteen injectors restore reservoir pressure with treated produced water — which also solves the disposal problem the field would otherwise face as the water cut climbs past 60%.
Associated gas that Phase I flared is now compressed and sent 41 km to the Rish Dune plant, where it is treated and sold. That single change removes roughly 90% of the field's routine flaring and pays for the compression within four years at long-run gas prices.
Scope of work
- Infill drilling on 380-metre spacing with rotary steerable systems
- Second 20,000 bopd processing train and stabilisation column
- Produced-water treatment and reinjection into the aquifer
- Field gathering network extension — 62 km of flowlines
- Gas-lift compression and associated-gas capture to Rish Dune
- Camp expansion, 34 MW of on-site generation and site infrastructure
