In petroleum science, reservoir fluids are the fluids mixture contained within the petroleum reservoir which technically are placed in the reservoir rock. Reservoir fluids normally include liquid hydrocarbon (mainly Crude oil), aqueous solutions with dissolved salt, hydrocarbon and non-hydrocarbon gases such as methane and hydrogen sulfide [1] respectively.
A virgin reservoir may be under sufficient pressure to push hydrocarbons to the surface. As the fluids are produced, the pressure will often decline, and production will falter. The reservoir may respond to the withdrawal of fluid in a way that tends to maintain the pressure. Artificial drive methods may be necessary.
Formation fluid refers to the naturally occurring liquids and gases contained in geologic formations. [1] Fluids introduced during the drilling process are called drilling fluids. [2] Fluids in an oil or gas reservoir are called reservoir fluids. [1] The fluids flowing from the wellhead of an oil or gas well are called production fluids.
These two fluids are stored only in pore space in the rock matrix. Components of a petrophysical model of a water-wet reservoir rock. Due to the complex microstructure, for a water-wet rock, the following terms comprised a clastic reservoir formation: V ma = volume of matrix grains. V dcl = volme of dry clay. V cbw = volume of clay bound water.
Reservoir engineers could use the map as a part of their well drill planning. Reservoir engineering is a branch of petroleum engineering that applies scientific principles to the fluid flow through a porous medium during the development and production of oil and gas reservoirs so as to obtain a high economic recovery. The working tools of the ...
Production fluid, or well fluid, is the fluid mixture of oil, gas and water in formation fluid that flows to the surface of an oil well from a reservoir. Its consistency and composition varies. Fluids may be described by a multitude of characteristics including:
The assortment of drilling fluid pumped down the well during drilling and completion can often cause damage to the surrounding formation by entering the reservoir rock and blocking the pore throats (the channels in the rock throughout which the reservoir fluids flow).
An oil production plant is a facility which processes production fluids from oil wells in order to separate out key components and prepare them for export. Typical oil well production fluids are a mixture of oil, gas and produced water. An oil production plant is distinct from an oil depot, which does not have processing facilities.
