COSIA’s members have identified ‘Reliable Solvent and Non-Solvent Additives Measurement’ as an innovation priority, which if realized, would help accelerate adoption of solvent technologies and dramatically reduce the amount of water needed and emissions per barrel of oil produced.
Measurement of production rate and composition from a well is fundamental to effective reservoir management. It is used to identify optimization opportunities and impacts future performance predictions that underpin investment decisions. In addition to the flow rates of oil, water and gas, solvent recovery processes require measuring the solvent content of the produced hydrocarbon phase for surveillance and regulatory reporting purposes.
There are a variety of well measurement configurations deployed amongst industry such as 3 phase (gas, bitumen, water) separators, 2 phase (gas, liquid) separators with water cut sensors, Coriolis meters & water cut sensors, and Coriolis meters & sampling, among others.
Multi-phase Flow Measurement technology has improved yet there is still not an absolute, stand-alone, measurement device. Current technology requires clean separation and measurement of individual phases. Separating bitumen and water in a 3-phase test separator increase cost of already expensive vessel. In field deployments, separating gas from liquid to improve water cut sensor accuracy has been less accurate than needed. Sampling is a common fallback but is difficult logistically, expensive, time consuming, and has inherent accuracy concerns, as well as cost and safety implications.
Measurement technology is rapidly advancing, with many physical systems being replaced by advanced flow meters for phase measurement. As such, traditional measurement technologies are being replaced, which is driven by pad facility cost reduction initiatives that frequently target well measurement.
- Test separators & chemical injection are being increasingly replaced by multiphase flow meters (MPFM) & sampling
- Multiple MPFM vendor products available
- Alternative multiphase separation with reduced vessel size kits emerging
COSIA members wish to take advantage of new technology to allow for composition measurement in the oil phase and vapor phase.
