Upstream Petroleum Services

EnvApps has a solid track record in the upstream petroleum services market. Prior to becoming environmental consultants, principals and staff worked for many years in the petroleum field, including refinery design services and oil and gas exploration. Our current associates include managers with 40+ years of oilfield exploration, production, and operations experience in California, Alaska, and other locales worldwide.

In the last 20 years, many of the oil leases in Southern California have been developed for industrial, commercial, and even residential uses due to the upsurge in property values. EnvApps has provided the necessary environmental services to property owners and developers including site and health risk assessments, soil vapor surveys, vapor intrusion assessments, remediation, regulatory compliance, and lease closure. EnvApps and it’s associates can also provide well abandonment and site plan review services in accordance with California Division of Oil, Gas, and Geothermal Resources requirements.
