Low injectivity is commonly skilled in geothermal doublets put in in sandstone reservoirs. This even led to a shutdown of the Mezoberény (Hungary) geothermal website. An on-site marketing campaign was carried out at that website together with a stimulation aiming to reinforce the transmissivity of the sedimentary reservoir and the near-wellbore zone of this website.
Earlier research have concluded that inadequate injectivity could also be linked to a excessive pores and skin impact within the close to well-bore zone and pore-clogging together with the low internet sandstone content material of the fluvio-deltaic reservoir. At different websites, chemical or organic actions are the explanation for lowering permeability through the operation of the geothermal vegetation. In Mezoberény a chemical mushy stimulation primarily based on the injection of hydrochloric acid (HCl) was efficiently used to unclog and get well the nicely injectivity. Therefore, it’s attainable to retrieve favorable circumstances and function sustainably.
With a give attention to Mezoberény, a number of examples might be proven on the challenges and alternatives of utilizing sedimentary reservoirs for geothermal vitality manufacturing.
Dr Maren Brehme is a hydrogeologist aiming to grasp subsurface fluid circulation utilizing multidisciplinary approaches for sustainable geothermal exploration and exploitation methods with a robust give attention to fieldwork and real-scale information. Maren’s primary analysis goal is discovering new nicely areas throughout geothermal exploration and discipline growth and on optimizing sustainable geothermal vitality extraction and conversion.
Areas of experience are geothermal reservoir characterization, hydraulic, thermal and chemical information interpretation, enhancing reservoir efficiency and its sustainable use. Strategies and findings are primarily associated to geothermal techniques however relevant in any geofluids atmosphere (geothermal, CO2, H2, warmth, ingesting water).
