Large-scale Physical Modeling of Water Injection into Geothermal Reservoirs and Correlation to Self Potential Measurements
Laboratory measurements of electric self potentials resulting from water injection through a known flow path in a 260 mm cube of Nugget sandstone are used to calibrate a new large-scale testing device that simulates the in-situ conditions at an injection point in a geothermal reservoir. Modeled in-situ temperatures were 20?C and 150?C, while injection pressures were varied from 1 to 1200 kPa. T...
متن کاملCold - Water Injection into Single - and Two - Phase Geothermal Reservoirs
Numerical simulation techniques have been employed by several suthors (see e.g. Benson and Approximate analytical solutions a rived for Bodvarsson, 1982; Garg and Pritchett, 1384 to cold water injection into single0-phase “porous medium” geothermal reservoirs. A (liquid) and two-phase (liquid water/steam) numerical geothermal reservoir simulator is used “porous medium” reservoirs. Injection of ...
متن کاملTemperature and injection water source influence microbial community structure in four Alaskan North Slope hydrocarbon reservoirs
A fundamental knowledge of microbial community structure in petroleum reservoirs can improve predictive modeling of these environments. We used hydrocarbon profiles, stable isotopes, and high-density DNA microarray analysis to characterize microbial communities in produced water from four Alaskan North Slope hydrocarbon reservoirs. Produced fluids from Schrader Bluff (24-27°C), Kuparuk (47-70°C...
متن کاملThe Injection of Water into and Extraction of Vapour from Bounded Geothermal Reservoirs
When liquid is injected into a geothermal reservoir, a fraction of the liquid may vaporise if the reservoir is sufficiently hot. The vapour forms at an approximately p1ana.r liquid-vapour interface and diffuses towards the far boundary of the reservoir. If vapour is extracted froin the far boundary, then once the new vapour has diffused across the reservoir, the rate of production of vapour at ...
متن کاملInduced Microearthquake Patterns in Hydrocarbon and Geothermal Reservoirs: A Review
The injection or production of fluids can induce microseismic events in hydrocarbon and geothermal reservoirs. By deploying sensors downhole, data sets have been collected that consist of a few hundred to well over 10,000 induced events. We find that most induced events cluster into well-defined geometrical patterns. In many cases, we must apply high-precision, relative location techniques to o...
