OQ Exploration & Production (OQEP) has awarded SLB a contract covering the Bisat-B expansion production plant at the Bisat field in Block 60, onshore western central Oman.

The scope spans design, engineering, procurement, construction, and commissioning, plus four years of operations and maintenance support after startup, SLB said. The expansion will lift gross fluids handling capacity at the facility to 548,000 b/d. SLB set the completion window at 19 months from the award.

The contract marks the third phase of surface development at Bisat. SLB delivered the original Bisat-A plant in 2018 and the first Bisat-B facility in 2020, establishing the production backbone that this new expansion now builds on. Block 60, operated by OQEP, sits in Oman's central onshore trend, a basin that has drawn sustained upstream investment as the sultanate works to sustain and grow crude output from mature and secondary recovery schemes.

The Bisat-B expansion is an engineered debottleneck-plus-addition project rather than greenfield speculation: the contract is let, the capacity target is defined, and the clock on the 19-month schedule is running. That distinguishes it from appraisal-stage work elsewhere in the region, where development timing remains contingent on drilling results and final investment decisions.

For SLB, the award extends a production-systems footprint in Oman that already includes the two earlier Bisat plants. The four-year O&M tail on the contract also signals OQEP's preference for consolidated delivery — one contractor carrying the asset from front-end engineering through early operations.

The timing matters for Oman's production outlook. Gross fluids handling is the operative number here: as water cut rises across Oman's onshore fields, nameplate capacity for total fluids, not just oil, increasingly determines what a facility can process. A 548,000 b/d fluids ceiling gives OQEP headroom to sustain oil throughput as wellhead water volumes climb.

The watch item is execution against the 19-month schedule. First delivery from the expanded Bisat-B train will indicate whether OQEP can convert the awarded scope into incremental Block 60 production on time — and when the four-year O&M window formally begins.
