SFI Field Examples

PT. Caltex Pacific Indonesia , Duri Indonesia

Terralog has successfully implemented one of the largest deep well disposal projects for E&P waste streams using our SFI process. This SFI project is at the Duri oilfield in Indonesia.

This project is designed to inject 500 m3/day (3150 bbls/day) of production related waste streams (oily sludge, tank bottoms, etc).

Terralog's services on this project include: technical feasibility study, project design, complete SFI field operations and facility operations, engineering/technical support, and project management.

Terralog is currently the operator for the Duri SFI project. Terralog has been operating this project since December, 2002.

The primary waste stream for the SFI site is Oily Viscous Fluids (OVF; i.e. oily sludge)
From December 2002 to February 2010, the Duri SFI project has disposed of the following waste streams:
       • Approximately 3.09 million m3 (19.4 million bbls) of waste water and produced
           water (used as mix-water for the SFI process).
       • Approximately 898,000 m3 (5.65 million bbls) of OVF .

The SFI project has now made the Duri oilfield essentially a 'zero discharge' oilfield in terms of its OVF waste streams from production operations and a large portion of its waste water.

Terralog has injected all of these wastes back into the deep geologic formation sequence, from where the waste originated (i.e. returned the waste streams to place of origin).

Surface pits used for surface disposal sites have either been closed and/or decommissioned.

Terralog and the client are satisfied with the SFI project performance level and environmental achievements of SFI operations at Duri.

Chevron, Crude Contaminated Soil Disposal Project

Terralog Technologies managed a project to dispose of crude contaminated soil through slurry fracture injection at an urban oilfield in California which was abandoned for real estate development.

This was the first surface soil injection project in North America . Terralog helped define the regulatory requirements for injection of this class of materials through our active participation and interaction with the US Ground Water Protection Council, the US EPA, and the California Department of Conservation, Division of Oil, Gas and Geothermal Resources (DOGGR).

Chevron, Port Fourchon NORM Disposal Project

Terralog Technologies provided project management and technical support to dispose of soils from disposal pits and canal bottoms which were contaminated with Naturally Occurring Radioactive Material (NORM). SFI was chosen as the disposal technique since it is a permanent disposal option, minimizes environmental liability, and cost less than transporting the canal soils to a NORM approved landfill.

From November 1998 to March 2000, a grand total of 1,000,800 bbl of NORM contaminated soil was disposed into two sets of formations with the City of New Orleans #2 (CNO#2) injection well.

Koch Exploration

Terralog provided project management, regulatory support, technical support, and complete injection services to dispose E & P waste for Koch Exploration.

The waste streams provided included produced sand, oily viscous fluid (OVF) and tank bottoms from Koch's production near Charlotte Lake, Alberta.

Terralog disposed of approximately 25,000 m3 of E & P waste over a seven month period.
