Two main pipelines were included in the system. The Stah/Mereksen Pipeline, 60 kilometers long and 16 inches in diameter, transported gas from two producing fields to the Alrar plant. The pipeline was designed for a pressure of 96.7 bars at 71.1° C. A 10-inch diameter, 45-kilometer condensate pipeline ran between Alrar and an existing pipeline at Ohanet. Designed for a pressure of approximately 69 bars, it could deliver up to 11,300 Nm³/day of hydrocarbon condensate.

The gas gathering system at the Alrar field collected gas, which was corrosive due to the presence of carbon dioxide and free water, from 22 production wells and delivered it to the treating plant battery limits. The approximate total length of the gathering system was 75 kilometers. Pipe diameters ranged in size from 30 inches at the plant inlet to 14 and 16 inches at individual trunk branches.

A gas reinjection system delivered dry residue gas from the treating plant for injection into 23 field wells through a network of pipelines and headers. With an approximate length of 63 kilometers, the system was designed for pressure of 320 bars.

The pipeline facilities featured a comprehensive telecontrol-telecommunications system. This system telemeasured flow rate, pressure and temperature. It also provided direct access between the treating plant and each well by telephone and allowed each well to be shut from the plant control room. The pipeline was protected from external erosion by a cathodic protection system.
