Industry overview

Oil & Gas

Oil and gas operations carry complex environmental aspects across upstream, midstream and downstream activities: flaring and venting, fugitive hydrocarbon emissions, produced water, drilling muds and cuttings, oily sludges, tank bottoms, contaminated soil and the risk of spills from pipelines and storage. Operators and their contractors work under the Environmental Law and its Implementing Regulations and, in many cases, under detailed company environmental standards that contractors must meet.

For service companies, fabrication yards and contractors supporting the sector, environmental performance is often a prequalification and contract requirement. They need permits for their own facilities, structured waste and chemical management, monitoring data, and records that satisfy both national requirements and client audits. Facilities in Jubail, Ras Al-Khair and Yanbu also work within the Royal Commission for Jubail and Yanbu (RCJY) environmental framework.

Methane and flaring reduction, carbon capture and emissions transparency are now central to the sector's sustainability agenda. Reliable GHG data, including methane, and clear reporting aligned with recognised frameworks help companies respond to investors, customers and the national climate commitments.

Environmental challenges

Environmental challenges

01

Flaring and fugitive emissions

Flares, vents, tanks and leaking components release hydrocarbons and methane that must be quantified, monitored and reduced.

02

Drilling and process wastes

Muds, cuttings, oily sludges and tank bottoms are hazardous waste streams that need characterisation, approved treatment and full traceability.

03

Produced and oily water

Produced water and oily wastewater must be treated and monitored before reinjection, reuse or discharge in line with approval conditions.

04

Legacy contamination

Older sites, yards and pipeline corridors may carry hydrocarbon contamination that affects acquisitions, lease handbacks and remediation planning.

05

Client audits for contractors

Contractors and service companies face frequent environmental audits from operators and must show permits, procedures and records on demand.

Typical requirements

Typical requirements

Requirements vary by activity, location and permit conditions. We confirm the applicable requirements for your project at the start of every engagement.

  • Environmental impact assessment and permits for new facilities, expansions and drilling programmes
  • Emission inventories and monitoring for flares, stacks, tanks and fugitive sources
  • Produced water and wastewater monitoring for the approved disposal route
  • Hazardous waste characterisation, storage, transport and treatment through licensed contractors under MWAN regulations
  • Spill prevention, response planning and soil and groundwater assessment
  • Contractor compliance with operator environmental standards and audit requirements
  • GHG and methane reporting aligned with the GHG Protocol and ISO 14064-1

How Selorin supports

How Selorin supports

  1. Studies and permits

    We prepare EIAs and permit applications for facilities, yards and expansions, and support responses to authority and client review.

  2. Audits and due diligence

    We audit facilities and contractors against regulatory and client requirements, and assess contamination risk for acquisitions and site handback.

  3. Air, water and waste programmes

    We monitor emissions and water quality, map hazardous waste streams and set up tracking that supports inspection and client audits.

  4. Methane, carbon and ESG

    We quantify GHG and methane emissions, identify reduction opportunities and structure ESG disclosures for investors and customers.

Relevant services

Environmental Permitting

Construction and operating permits, renewals and modifications — from permit strategy and document preparation to submission and responses to authority comments.

Key benefit: Fewer resubmissions and a clearer path to permit decisions

Environmental Impact Assessment

Screening, scoping, baseline studies, impact analysis and mitigation, prepared as an EIA report ready for authority review and follow-up comments.

Key benefit: A defensible EIA that keeps your approval path predictable

Environmental Audits

Compliance audits, gap assessments and ISO 14001 internal audit support, with structured reports that rank findings by significance and recommend practical actions.

Key benefit: An objective view of where you stand and what to fix first

Environmental Due Diligence

Pre-transaction assessments for acquisitions, investments, leases and land transfers: site history, inspection, contamination risk screening and compliance and liability findings.

Key benefit: Environmental risks known before the deal, not after

Air Quality Monitoring

Ambient air quality monitoring for gases, particulates and meteorology, plus stack emissions measurement, with validated data and compliance-ready reports.

Key benefit: Clear evidence of air quality performance for permits and stakeholders

Water Quality Monitoring

Sampling and monitoring of effluent, treated wastewater, groundwater and seawater, with on-site measurements, laboratory coordination and compliance reporting.

Key benefit: Confidence that discharges and reuse meet permit conditions

Waste Management

Waste classification, audits, waste management plans, segregation and storage, transporter and receiver checks, and documentation for MWAN compliance.

Key benefit: Compliant waste handling with a clear, traceable chain of custody

GHG and Carbon Accounting

Scope 1, 2 and 3 emissions inventories prepared under the GHG Protocol and ISO 14064-1, with documented methods and verification-ready records.

Key benefit: An emissions baseline you can report, verify and reduce

ESG Advisory

Materiality assessment, ESG data controls and reporting aligned with GRI, IFRS S1/S2 and Saudi Exchange guidance, plus support with investor questionnaires.

Key benefit: Credible ESG disclosures backed by traceable data

Frequently asked questions

We are an oilfield service contractor. What environmental documents will operators ask for?

Typically your environmental permits, an environmental management system or plan, waste and chemical handling procedures, monitoring records and incident reports. We review your current documents against the client's requirements and close the gaps before prequalification or audit.

How do you assess hydrocarbon contamination at an old yard?

We start with site history and a walkover to identify likely source areas, then design targeted soil and groundwater sampling. Results are compared against applicable criteria and used to recommend whether remediation or further investigation is needed.

Can you quantify methane emissions from our facilities?

Yes. We build an emissions inventory covering flaring, venting and fugitive sources using recognised calculation methods, and identify where measurement would improve accuracy. The results support reduction planning and reporting.
