Guadalupe Oil Field Remediation and Deconstruction

This 3,000-acre oil field is in a pristine environmental preservation habitat adjacent to the Pacific Ocean. After 50 years of oil production, the leasee closed its operation. A production infrastructure of 168 miles of pipelines and 240 wells required deconstruction. After significant characterization studies, the client determined that diluent plumes existed under approximately 187 acres of the oil field. Remediation projects included full excavation of plumes and/or sumps; partial excavation with in-situ recovery systems; active product recovery; bioremediation of excavated soils; and other actions approved by the Regional Water Quality Board, such as in-situ remediation, biodegradation in the Land Treatment Unit, and phytoremediation.

Cannon was selected to provide engineering, surveying, and permitting and compliance services for this project. The scope of work included an implementation plan; plans and specifications for grading and drainage, removal of approximately 300,000 cubic yards of hydrocarbon affected material, and removal of 30,000 cubic yards of sump material; road construction; layout of approximately 7,000 feet of sheet pile wall; emergency permitting and agency approvals; construction management; and pipeline abandonment. The project cost was more than $20M.
