Filtered Seawater Particle Counts for Injection into Oil Reserves
Seawater injection is a secondary recovery technique used in oil reservoirs to replace extracted oil and maintain well pressure. Oil reservoirs are typically found within the small pores of sedimentary rock formations, so it is imperative that the injected seawater does not contain suspended particle matter that can clog these pores and hinder oil recovery. Since untreated seawater contains significant quantities of suspended particle matter it is generally filtered prior to injection into oil reservoirs. Optical particle counters offer an accurate and reliable solution to quantify particle concentrations in filtered seawater used for injection.
Particle Contamination in Chemical Distribution SystemsAdvanced Data Analysis Strategies
Particle contamination in chemical distribution systems can be difficult to find, but costly to yield when missed.
Advanced data analysis techniques can be implemented to quantitatively assess particle contamination data in state-of-the-art chemical distribution systems. Through examining the distribution of the rate of particle detection compared to Poisson’s distribution, it is possible to determine if particle variations are random or systematic and allow for the focus of improvement efforts to reduce particle levels with time. By analyzing the particle contamination data in the frequency domain via Fourier transform analyses, periodic cycles of contamination can be identified with the goal of associating contamination events with activities within the chemical delivery system.
