Oilfield Waste

Terralog provides an integrated package of on-site waste injection, design, operations, and monitoring services at competitive turnkey prices. The Slurry Fracture Injection (SFI) process involves slurrification of oilfield wastes with produced water and reinjection into appropriate formations. The mix water can be a waste fluid, such as produced water from oil production operations. The unique aspects of the SFI process allow Terralog to dispose of granular and/or viscous sludge materials.

A variety of oilfield wastes, including produced sand, tank bottom sludges, and crude contaminated soils, are generated during drilling operations, production, and storage processes. Crude oil contaminated sands or soils are generally designated as nonhazardous wastes by regulatory agencies. However, these materials still must be disposed of in an environmentally acceptable manner. The problems can become most pressing as oil fields in urban areas reach the end of their productive lives and the properties are redeveloped for residential or commercial use. The technique offers a number of economic and environmental advantages for disposal of oilfield wastes. When reinjecting into depleted oil sands, the crude waste is simply being returned to its place of origin.

SFI is an environmentally & technically viable process that can be used as part of an effective waste management program to deal with contaminated soils & municipal wates.

An economically and environmentally sound solution is injection of these oilfield wastes into subsurface sand formations through the Slurry Fracture Injection process. Slurry injection has been used to dispose of drilling muds and cuttings in Alaska, the Gulf of Mexico, and the North Sea; naturally occurring radioactive materials in Alaska and the Gulf of Mexico; and large volumes of produced oily sand and tank bottoms in the provinces of Alberta and Saskatchewan, Canada.

Long-term liability to the operator is significantly reduced, in marked contrast to surface storage or landfill disposal. Finally, fracture injection costs are lower than typical roadspreading, transport and landfill disposal costs for large quantities of waste.

Terralog can efficiently manage your waste disposal needs by providing a full suite of services including design, permit application and regulatory support, injection operation, monitoring, and reporting.

The net result will be lower costs and reduced environmental liability to your company.
