Innovative Engineering Benefits the Environment
Currently, 30 mmsfcd from the El Gassi and adjacent Zotti fields is flared daily as a normal course of operating. However, in keeping with its environmental protection campaign to reduce polluting emissions globally, this operator retained BJ PPS to design, build, commission and operate the two gas injection compression units to carry out "early gas injection" services for 33 months from commissioning of the system.
Now that the gas injection compression spread has begun operating, BJ PPS uses the spread to repressurise 30 mmsfcd from very low supply pressures of 2, 4 and 39 bar, up to a high pressure discharge of 300 bar.g in order that it may be re-injected back into the reservoir. By doing so, the environmental emissions from the El Gassi LP and HP flares are being reduced to minimal levels.
New Units Feature Most Powerful Engines in BJ Services Fleet
Key elements of each gas injection compression unit include: a Waukesha 16VAT27GL low Nox emission, turbocharged, natural gas-fuelled engine with a maximum power of 4500bhp; a Dresser Rand 7HOS-6 gas compressor; a Fintube cooler for process gas after-cooling; a Jacket Water Cooler; clean oil storage tanks, waste oil storage tanks and a glycol storage tank, among a host of additional items.
While primary support of the operation is being supplied by four specially trained, mechanical field supervisors on-site at El Gassi, BJ PPS personnel located at division bases in Hassi Messaoud, Algeria and Great Yarmouth, UK also provide ongoing assistance.
