Profile: FourQuest Energy Inc provides pre-commissioning, regular shutdown and maintenance services to the energy industry. We offer services such as nitrogen, air, oil flushing, fluid pumping, chemical cleaning, steam blowing, engineering and remedial services to oil and gas business sector. Our nitrogen services can be delivered to the site in a variety of methods; as a cryogenic liquid, compressed dry gas bottles/filtered from the atmosphere at site using a nitrogen membrane unit. The most common treatment method used is to deliver the nitrogen to site in bulk as a cryogenic liquid, and convert it to a warm dry gas using a diesel fired heat exchanger on the pumping unit. The nitrogen gas can be delivered at temperatures ranging from -150 to +400 C & pressures starting at atmospheric and up to 10,000 PSI. Our lube oil flushing services are used to extend the life cycle of lubrication systems during commissioning and following periodic maintenance & repair services. Our pumping services can be used to provide an efficient method of removing debris from pipelines & to build new facilities by exceeding the cleaning force ratio & abrading debris and scale from the internal surfaces of the vessel & pipe walls. The debris laden fluid can be filtered & re-injected to remove additional debris. Other applications range from high pressure water injection into under-pressured formations to enhance oil recovery to water disposal, to injecting large volumes of water into pipelines, process units/storage vessels for hydrostatic testing.
