Environmental Services For Oil and Gas

Environmental Services For Oil and Gas


Environmental consulting and remediation for the oil and gas industry plays a huge role on minimizing environmental contamination risks and liabilities that may be caused by active oil & gas exploration and production activities.

Oil & gas lease properties as well as those properties to be developed that are affected by historical oil and gas activities are good candidates for assessment, corrective action, and regulatory agency closure. CRG Texas offers a variety of environmental services that can help our land owners, oil and gas companies, and lease operators minimize those risks. Following all federal, state, and environmental regulations as well as standard industry environmental due diligence, our staff of scientific experts make sure that each project is done to exceed all expectations between stakeholders.

Environmental Services For Oil and Gas


Confidential Site – Houston, Texas

CRG Texas completed the necessary environmental assessment activities and corrective action requirements to assist one of our clients manage environmental risks associated with a commercial property slated for development in Houston, Texas. After conducting Phase I ESA for the property, former gun range and oil & gas exploration and production activities were identified at the subject site. Phase II ESA sampling and laboratory chemical analysis confirmed the presence of total lead in soil at the gun range, and confirmed the presence of petroleum constituent chemicals in soil and groundwater in excess of published concentrations.

The affected soil at the gun range area was regulated by the Texas Commission on Environmental Quality (TCEQ) and the affected sol and groundwater at the oil & gas area was regulated by the Railroad Commission of Texas (RRC). The affected media at each area was delineated and reported to both the TCEQ and RRC. The subsequent corrective action required included the preparation and submittal of corrective action plans, site remediation, and preparation of associated remediation reports to receive no further action confirmation by the TCEQ and RRC.
