FEED for Extension of Manifolds at Jaleha, FS & KMDS, Qatar

Qatar Petroleum (QP) has planned to drill a number of oil producing wells all over Dukhan fields in the coming years to enhance oil production. In the existing Jaleha North and South Manifolds, Fahahil South Manifold and Khatiyah Main Manifold, located in the respective Degassing Stations, sufficient free slots are not available to connect the new wells. It is, therefore proposed to create eight (8) new additional slots, into one modular manifold, in each of these locations for future connection of new wells. Each module of eight (8) slots is required in Jaleha North and South Manifolds, Fahahil South Manifold and the West side of Khatiyah Main Degassing Stations.

The Project objective is to provide thirty two (32) additional slots - one set of additional eight (8) slots modular manifold close to each of the four existing manifolds area, namely at Jaleha North and South Manifolds, Fahahil South Manifolds and Khatiyah Main West side Manifolds area (hereinafter referred as “Project”). The design of new manifolds shall be conventional type similar to the existing, with the slots catering to the new 6” flow lines.

The manifolds shall have provision to divert the flow of each well either to Station Production Separators or to any of the Test Separators.
