Oil & Gas
Oil and gas facilities carry detailed environmental obligations from construction through operation and decommissioning. We help operators and contractors keep permits, records and site controls in order at each stage.
Upstream, midstream and downstream activities interact with air, soil, groundwater and the marine environment in different ways. Each facility therefore faces its own mix of permit conditions, monitoring duties and reporting requirements, and these change as a project moves from design to construction to operation.
Lothan works alongside operators, EPC contractors and service companies to identify the obligations that apply, prepare the documentation the Environment Public Authority and other competent bodies expect, and follow up until conditions are met. Where a specialist study or treatment technology is needed, we coordinate it through licensed Lothan Group companies or approved technical partners.
Sector challenges
- 01
Produced water and process effluent
Water separated from oil and gas and other process streams must be handled, treated or reinjected under controlled and documented conditions.
- 02
Flaring and air emissions
Flares, heaters, compressors and fugitive sources generate emissions that need to be inventoried, monitored and reported.
- 03
Contaminated soil and legacy sites
Spills and historical operations can leave hydrocarbon contamination that has to be assessed, managed and documented.
- 04
Multiple permits across project phases
Construction, commissioning and operation often require separate approvals, each with its own conditions and renewal cycle.
How we help
- 01
Effluent management planning
We document produced water and effluent streams, review handling options with technical partners and prepare the records that discharge or reinjection conditions require.
- 02
Emissions inventory and monitoring plans
We help build an inventory of emission sources and set up monitoring and reporting routines that match permit conditions.
- 03
Contamination assessment coordination
We coordinate site investigations and remediation planning through qualified entities and keep the findings organized for the authorities.
- 04
Phase-by-phase permit roadmap
We map the approvals each phase needs, track conditions and renewals, and keep one register so nothing is missed at handover.
