Pars Oil and Gas Co. (POGC) has commissioned the first well of a 35-well infill drilling program at the South Pars field in the Persian Gulf.
CEO Touraj Dehqani told news service Shana that well No. 5 at the Phase 12 SPD12B production platform had been completed and connected to the platform’s existing processing facilities.
The well has a production capacity of more than 2 MMcm/d of rich gas. It is designed to offset natural reservoir depletion at the SPD12B platform location and restore the facility’s production to its initial design capacity.
Drilling of the 35 wells has been split into four work packages, with POGC and Petroiran Development Co./International Drilling Co. (DCI) managing the initial work using the DCI-2 offshore drilling rig.
Altogether, infill drilling will take place from 17 gas platforms across South Pars, raising the field’s daily gas production capacity by 36 MMcm.
In another Shana report, POGC said an ongoing strategic pressure enhancement project for South Pars gas is designed to increase the field’s overall recovery rate from 54% to 75%.
The projects’ senior executive Mohammad-Mehdi Tavasolipour said, “We have recently entered the second half of the field’s production life. Like all gas and oil fields worldwide, which experience pressure and production declines in their second half, we had to prepare for this scenario.”
POGC examined more than 20 scenarios for arresting the pressure decline, with onshore and offshore pressure enhancement, or a combination of both. The offshore solution took into account economic and environmental factors and execution feasibility.
Plans call for offshore hubs featuring two pressure enhancement platforms with a capacity of 1 Bcf/d, two power generation platforms, and two quarters platforms to accommodate 120 operations personnel.
Tavasolipour added that more than 40 km of subsea pipelines and 42 offshore platforms, along with more than 600 km of pipelines, will connect wellhead installations to the pressure enhancement platforms.
