Gas and Liquid Measurement Services
Accurate, defensible measurement for upstream and midstream oil and gas operations. From meter installation and calibration to SCADA integration, data validation, and production allocation. When every BTU and every barrel counts, SPL gets the numbers right.
SPL’s Measurement division provides comprehensive gas and liquid measurement services, meter calibration, automation and SCADA support, data validation, and production allocation across upstream and midstream oil and gas environments. Our field technicians install, maintain, calibrate, and troubleshoot meters and control systems, while our data services team validates and audits volumetric measurement data to ensure accuracy, regulatory compliance, and financial accountability at every custody transfer point. With decades of measurement experience and field teams embedded across key producing regions, SPL delivers the technical depth and operational responsiveness that keeps your measurement program running with confidence.

Your Operations Don't Stop. Neither Do We.
Expert Technican Support
Safety First Field Operations
SPL field technicians can be scheduled, on-call, or embedded in your operations. They get to know your equipment, your sites, and your measurement history. Reliable, highly-trained, and knowledgeable partners you can trust.
Every SPL field technician prioritizes safety and maintains a clean, professional work environment on your sites — operating to your site safety requirements as a baseline, not an afterthought.
Customized Consulting
Portable GC, H2S, and TVP Testing
Beyond installation and calibration, SPL’s measurement specialists provide technical advice rooted in industry standards and regulatory requirements — helping you navigate AGA, API, and state-specific measurement rules.
On-site portable gas chromatography analysis, Hydrogen Sulfide (H2S), and True Vapor Pressure testing capabilities that deliver real-time data at the wellhead — no waiting for results when you need to make operational decisions in the field.
Data Validation Beyond Standard Reporting
Most measurement service providers give you software-generated reports. SPL goes further. Our data validation process layers a rigorous, expert-reviewed audit over every report before it leaves our team, combining automated audits with multiple levels of human review and corrective action.
The result: measurement data that protects you from costly custody transfer disputes, compliance risk, and revenue uncertainty. Every proving result arrives with the confidence that it has been checked, validated, and verified by people who understand what the numbers mean.
Frequently Asked Questions About SPL Measurement Services
What gas measurement services does SPL provide?
SPL provides comprehensive gas measurement services including SCADA and communications setup, end-to-end system design, custom HMI programming, automation software configuration, meter installation, programming and troubleshooting, portable GC analysis, sample collection, H2S testing, and embedded technician support across production and midstream environments.
What is meter proving and why does it matter?
Meter proving is the process of verifying that a flow meter is measuring accurately against a known standard — and it is the foundation of defensible custody transfer. Inaccurate meters create revenue loss, partnership disputes, and regulatory exposure. SPL provides custody transfer proving, allocation proving, master proving, and pull-and-clean proving backed by advanced data analytics that track meter behavior over time.
What is Production Allocation and does SPL offer it?
roduction Allocation is the process of calculating each party’s share of oil and gas production and sales across a delivery network. SPL provides production allocation services through SurePhase, our proprietary allocation system, for upstream and midstream facilities — including complex tiered networks and equation-of-state models for phase change calculations.
Does SPL offer embedded field technician support?
Yes. SPL field technicians can be embedded directly within client operations, not dispatched reactively from a service center. Embedded support means your SPL technician knows your equipment, your sites, and your measurement history, providing faster response and more consistent service than traditional call-out arrangements.
What is OOOOb compliance and can SPL help?
EPA’s OOOOb regulations require operators to validate Net Heating Value or BTU content of flare gas over a 14-day period. SPL provides turnkey OOOOb NHV sampling and analysis using our Dual Heated Composite Sampler or Manual Composite Sampling, with BTU data certified through ASTM D1945 analysis.
Your Measurement Program Deserves a Partner Who Gets It Right
Whether you need meter calibration, embedded field support, data validation, production allocation, or a fully managed measurement program, SPL has the people, the systems, and the field presence to deliver.
