Oil & Gas Estimating Services for Upstream, Midstream & Downstream Contractors

Oil and gas estimating is the process of calculating the total costs for upstream, midstream, and downstream oil and gas facilities, including well pads, pipelines, refineries, processing plants, and storage terminals. It covers materials, equipment, labor, and installation costs. Accurate oil and gas estimates are important because they help contractors and EPC firms submit competitive bids, manage project budgets, ensure regulatory compliance, avoid cost overruns, and maintain profitability in a capital-intensive industry where millions of dollars are at stake.

Our oil and gas estimates achieve 99% accuracy through advanced estimating software, experienced estimators with backgrounds in oil and gas construction, and rigorous quality control. We use current pricing databases for specialty equipment including separators, compressors, pumps, and storage tanks, and we account for regional labor rates and material cost fluctuations. We follow AACE International best practices and are familiar with API standards, ASME codes, and OSHA PSM requirements, ensuring professional-grade accuracy for bidding and budgeting.

We provide comprehensive oil and gas estimating services across all sectors including:

• Upstream: Well pads and production facilities
• Midstream: Pipelines, pump stations, compressor stations and storage terminals
• Downstream: Refineries, petrochemical plants, and LNG terminals

Our estimators have experience with ASME B31.4/B31.8 pipeline systems, API 650/620 storage tanks, and all major oil and gas facility types and project sizes.

Our standard turnaround time for oil and gas estimates is 24 to 48 hours for most projects. The exact timeline depends on project complexity, facility size, and the level of detail required. For urgent estimates, we offer expedited services with same-day or next-day delivery. Larger refinery or LNG terminal projects may require 3 to 5 business days to ensure comprehensive analysis covering all process units and piping networks. We will provide a specific timeline when you submit your project plans and specifications.

To provide an accurate oil and gas estimate, we typically need:

• P&ID drawings and process flow diagrams
• Piping and instrumentation diagrams
• Equipment schedules and data sheets
• Plot plans and facility layout drawings
• Project specifications and scope of work
• Pipeline alignment sheets and cross sections
• Geotechnical reports for pipeline routing
• Site location and local regulatory requirements
• Project timeline and schedule constraints
• Any special requirements or vendor quotes for specialty equipment

The more detailed information you provide, the more accurate your estimate will be.

Our comprehensive oil and gas estimate package includes:

• Detailed material takeoffs for piping and valves
• Equipment counts and costing
• Pipeline quantities including pipe, coating, and fittings
• Instrumentation and control system counts
• Civil and structural quantities for foundations and supports
• Electrical and heat tracing quantities
• Material costs with current pricing
• Labor hours and costs by craft
• Marked-up P&ID and alignment drawings
• Excel spreadsheet with itemized line-item costs

All deliverables are provided in easy-to-use formats that you can use directly for bidding or budgeting.

Our oil and gas estimating service pricing varies based on project size, complexity, and turnaround requirements. We offer competitive rates that are significantly more affordable than hiring in-house estimators or engineering firms. Pricing typically ranges from $500 to $2,000 for small well pad or pipeline projects and $2,000 to $10,000 or more for large refinery or LNG terminal projects. We provide custom quotes based on your specific needs. First-time clients receive a 30% discount, and we offer volume discounts for EPC contractors with multiple projects.

Yes, we provide detailed estimates for both onshore and offshore oil and gas facilities. Our estimating covers:

Whether your project is in the Permian Basin, Bakken Shale, Gulf of Mexico, or North Sea, our team has the expertise to deliver accurate estimates for your specific operating environment.

Absolutely. We provide comprehensive estimates for both upstream and downstream oil and gas facilities. Our upstream estimating covers well pad construction, drilling rig setup, production separators, heater treaters, dehydrators, tank batteries, and gas gathering systems. Our downstream estimating covers refinery process units including crude distillation, catalytic cracking, hydrotreating, reforming, alkylation, and delayed coking, as well as petrochemical plants and LNG liquefaction and regasification terminals. Our estimators understand the unique requirements of each sector.

We proudly serve oil and gas contractors and EPC firms across:

Our virtual service model allows us to work with clients globally without geographic limitations. We are familiar with regional cost variations, local regulatory requirements, labor market dynamics, and material pricing across multiple continents. Whether your project is in Houston, Midland, Calgary, Perth, Aberdeen, or anywhere in between, we provide accurate, localized oil and gas cost estimates tailored to your specific market conditions.
