Improving flare measurement

Overview Accurately measuring flare gas flows helps oil companies comply with industry regulations on emissions, conserve energy and measure how much gas they are venting. The high turndown ratio of our Focus® Optical Flow Meter is not only easy to install and cost-effective, but its high turndown ratio allows oil companies to measure a wide range of flow rates.
The challenge Flaring is the burning of the waste natural gas associated with oil production. According to World Bank estimates, more than 150 billion cubic meters of gas are flared or vented into the atmosphere every year (approximately the annual gas consumption of Germany and France combined), adding to the greenhouse gas emissions associated with global warming. In addition, flaring has triggered allegations of serious health consequences on people and animals.
Our solution One of the challenges in reducing flaring has been finding an accurate way to measure the amount of gas being flared. However, the highly technical problem can now be effectively addressed using sophisticated sensor technology. Download the Focus OFM White Paper
How does it work? Our Focus Probe meets the five challenges of effective flare measurement.
1. It’s the right technology Principle operation of the Focus Probe is laser-based optical sensing which enables it to handle variable gas compositions while maintaining the accuracy to within 1% (from 1m/s-30m/s) over a turndown ratio of 1500:1.
2. Designed for high dynamic flows Photon Control’s Focus Probe was designed specifically for gas flare metering and its highly variable flow rates.
3. Unaffected by low pressure and unknown gas composition By using a laser system to measure particle velocity, the accuracy of the Focus Probe is not affected by the composition of flare gas. The use of optics is a major functional advantage for flare metering.
4. No installation and maintenance challenges With its simple, effective design, the Focus Probe is specifically engineered for flare measurement. Requiring only one weldolet, the innovative design requires no in-field calibration, eliminating the need to stop operations for either calibration or routine maintenance.
5. Cost-effective compared to conventional systems Ultrasonic technology is cost-prohibitive and experiences problems related to performance accuracy and sound interference, while hermal mass meters cannot cope with the highly variable composition of flare gases. Optical metering is an accurate cost effective solution customized for flare applications.

Creating efficiencies in the oil sands

Overview Being able to accurately and reliably measure pressure and temperature In oil sands production is vital to oil sands companies for environmental, operational and public relations reasons. We designed our Downhole Pressure Temperature System (DHPTS) specifically to meet the demanding needs of the Steam Assisted Gravity Drainage (SAGD) process required to efficiently extract the bitumen from oil sands projects.
The challenge Major Oil and Gas companies are investing significant dollars in developing oil sand resources around the world, many using the Steam Assisted Gravity Drainage (SAGD) technique. In a SAGD process, the temperature and pressure of the steam required to efficiently extract the bitumen are considerable – with temperatures as high as 300°C and pressures exceeding 10 MPa.
Our solution We designed our DHPTS to accurately measure temperature and pressure during SAGD production to optimize processes, reduce the severity or impact of problem wells, enhance safety for pressure control operations and create long-term production cost efficiencies.
How does it work? The sensing elements are hermetically sealed within a stainless steel probe and are resistant to “hydrogen blackening”. The DHPTS boasts accurate high pressure and temperature range as well as a Spectral Multiplexer with 8 or 16 channels. The Probe is connected to the interface electronics with optical fibers, housed within a stainless steel cable; the cable can be up to 5000 m in length. The sensor’s immunity to electromagnetic radiation means that our probes can be run directly in line with the high voltage lines used in SAGD applications, allowing measurements to be made right at the pump – where they are meant to be made.
