POGC intent on widespread pressure boosting at South Pars gas field offshore Iran

Pars Oil and Gas Co. (POGC) has drawn up plans for pressure boosting at seven offshore hubs at the South Pars gas field in the Persian Gulf.

To speed up the process, pressure boosting for the first hub will also be implemented onshore, according to news service Shana.

POGC CEO Touraj Dehqani said South Pars had entered the second half of its predicted lifespan. The new program is designed to prevent anticipated pressure decline, allowing production to continue for more than 20 more years.

With pressure boosting, the closer the equipment is to the source, the greater the long-term value, Dehqani added. But while offshore pressure boosting is the priority, there are some concerns over how quickly this can be implemented versus onshore boosting.

However, offshore execution remains the preferred option in the longer term.

POGC hopes to have the first pressure-boosting hub in place by 2030, connected to South Pars Phase 12 and Phase 11. Onshore pressure boosting here should speed up the development, he added, with an estimated cost of $300 million to $400 million.

South Pars 11 gas well undergoes enhancement measures

Earlier this year, acidizing operations finished at the SPD11B platform on the 12^th well of the South Pars Phase 11 gas development. The well, which is the seventh drilled from this platform, had gone onstream in early November 2024, according to news service Shana.

Following pressure testing, the acidizing operation took place Dec. 31 using the Deep Cleaner specialist vessel, with the purpose being to maximize well performance and enhance production capacity.

Flowback operations are underway to clean up the well. Work will continue to improve gas flow and productivity and increase daily gas output from Phase 11, the report added.

POGC completes South Pars overhaul campaign offshore Iran

In December 2024, POGC completed overhauls of the gas platforms at the South Pars field.

Ali-Mohammad Tahan, head of HSE at the company’s Operations and Support Division, told news service Shana the program was designed to maximize gas production.

For this year’s campaign, 4,225 work orders were issued, with 2,274 of these completed successfully on the platforms in Zone 1, and the remainder on installations in Zone 2.

Activities included isolating pipelines; replacing 13 32-inch (ESDV and MOV) valves, each weighing about 20 t; replacing seven outlet bends; radiographic testing of lines post-replacement; pressure testing of wells on five platforms; clearing blockages in the flare pilot lines of eight platforms; and installing spark arresters on Platform 7.
