WebCapillary forces explain why water is retained in oil and gas zones. In water-wet reservoirs, water coats rock surfaces and is preferentially held in smaller pores. Nonwetting hydrocarbon phases occupy the central space of larger pores. Capillary pressure cannot be measured directly in a reservoir. WebJan 19, 2024 · Capillary pressure concepts can be used by geologists, petrophysicists, and petroleum engineers to evaluate the following: Reservoir rock quality Pay versus nonpay …
WebOct 26, 2024 · Groundwater seeps into rock cracks by capillary action and eventually evaporates. This yields salt crystals, which increase the pressure in rocks. Eventually the rocks will break down. This can leave pits of salt crystals that resemble honeycombs. The weathering from salt crystallization weathering is often found in dry climates.
