WS.PEMS
Real-time monitoring of regulated air pollutants meeting permit conditions without any hardware.
Weel & Sandvig has spent decades helping oil and gas operators build air quality monitoring programs that satisfy regulators and hold up under scrutiny. Our first-principles approach means the numbers behind your permit reports are grounded in the laws of physics.
From individual combustion sources to facility-wide emission totals, WS.PEMS gives you a shared, consistent view of where pollutants are being generated and what is driving them.
Industrial oil and gas facilities operate under strict emission permits covering NOₓ, SO₂, CO, and particulate matter. WS.PEMS monitors compliance around the clock, flagging potential exceedances before they become violations.
WS.PEMS derives air quality emission data from your existing process instrumentation using first-principles models. No new sensors, no additional infrastructure. That means no disruption to ongoing production for you.
The advanced modeling approach behind WS.PEMS is certified to international standards, giving you a documented, traceable trail for every figure submitted to regulators or included in environmental impact reports.
WS.PEMS provides a continuous, real-time view of regulated air pollutant emissions across all major combustion sources on site, such as gas turbines, flares, boilers, and engines. Our technology helps front-line staff and leadership to track performance and keep within permitted levels.
Early warning of emission trends means operations teams can adjust operating parameters and prevent exceedances before they trigger regulatory reporting obligations. Because the system runs on your existing instrumentation, there is no new hardware to maintain and no continuous interference with normal operations.


Meeting permit conditions is the minimum requirement. Demonstrating that you have a robust, defensible monitoring program in place is what builds long-term regulatory confidence. WS.PEMS produces standardized air quality reports aligned with the EU Industrial Emissions Directive, US EPA regulations, and the specific permit conditions of your facility.
Every reported figure carries full traceability back to the underlying process data and the physical model that generated it. When an environmental agency audits your records, or when permit renewal comes around, you have everything they need; documented and ready to present.
