One of the most common methods for evaluating geological formations is the use of wellManmade hole drilled into the earth to produce liquids or gases, or to allow the injectionThe process of using pressure to force fluids down wells of fluids logs. Logs are conducted by lowering an instrument into the wellManmade hole drilled into the earth to produce liquids or gases, or to allow the injectionThe process of using pressure to force fluids down wells of fluids and taking a profile of one or more physical properties along the length of the wellManmade hole drilled into the earth to produce liquids or gases, or to allow the injectionThe process of using pressure to force fluids down wells of fluids. A variety of wellManmade hole drilled into the earth to produce liquids or gases, or to allow the injectionThe process of using pressure to force fluids down wells of fluids logs is available that can measure several parameters from the condition of the wellManmade hole drilled into the earth to produce liquids or gases, or to allow the injectionThe process of using pressure to force fluids down wells of fluids to the composition of pore fluids and the mineralogy of the formationA body of rock of considerable extent with distinctive characteristics that allow geologists to map, describe, and name it. Permanent downhole measurements of pressure and temperature are standard for oil and gas production and likewise, e.g. in the Snøhvit CO2Carbon dioxide storage(CO2Carbon dioxide) A process for retaining captured CO2Carbon dioxide, so that it does not reach the atmosphereThe layer of gases surrounding the earth; the gases are mainly nitrogen (78%) and oxygen (around 21%) project, pressure and temperature are continuously measured every second in the CO2Carbon dioxide injectionThe process of using pressure to force fluids down wells wellManmade hole drilled into the earth to produce liquids or gases, or to allow the injectionThe process of using pressure to force fluids down wells of fluids.
WellManmade hole drilled into the earth to produce liquids or gases, or to allow the injectionThe process of using pressure to force fluids down wells of fluids logging in CO2Carbon dioxide storage(CO2Carbon dioxide) A process for retaining captured CO2Carbon dioxide, so that it does not reach the atmosphereThe layer of gases surrounding the earth; the gases are mainly nitrogen (78%) and oxygen (around 21%) projects will also be very useful for inspecting the condition of the wellManmade hole drilled into the earth to produce liquids or gases, or to allow the injectionThe process of using pressure to force fluids down wells of fluids and ensuring that the wellManmade hole drilled into the earth to produce liquids or gases, or to allow the injectionThe process of using pressure to force fluids down wells of fluids itself does not provide a leakage(in CO2Carbon dioxide storage) The escape of injected fluid from the storage formationA body of rock of considerable extent with distinctive characteristics that allow geologists to map, describe, and name it to the atmosphereThe layer of gases surrounding the earth; the gases are mainly nitrogen (78%) and oxygen (around 21%) or water column pathway for CO2Carbon dioxide. Several logs are routinely used for this purpose, including temperature, noise, casingA pipe which is inserted to stabilise the borehole of a well after it is drilled integrity, and radioactive tracerA chemical compound or isotope added in small quantities to trace flow patterns logs (Benson et al., 20022002 - S.M. Benson, R. Hepple, J. Apps, C.F. Tsang, M. LippmannLessons learned from natural and industrial analogues for storage of carbon dioxide in deep geologic formationssee more). However, the resolution of wellManmade hole drilled into the earth to produce liquids or gases, or to allow the injectionThe process of using pressure to force fluids down wells of fluids logs may not be sufficient to detect very small rates of seepage through microcracks (Benson and Myer, 2002).
A sonic log(well) Records taken during or after the drilling of a well is a porosityMeasure for the amount of pore spaceSpace between rock or sediment grains that can contain fluids in a rock log(well) Records taken during or after the drilling of a well that measures interval transit time (Δt) of a compression sound wave travelling through one foot of formationA body of rock of considerable extent with distinctive characteristics that allow geologists to map, describe, and name it. Sonic logging is essential to calibrate surface seismic methods. The sonic log(well) Records taken during or after the drilling of a well device consists of one or more sound transmitters and two or more receivers. However, in sonic logging only sound travel time is measured and additional data manipulation is required, e.g. compensation for borehole size variations as wellManmade hole drilled into the earth to produce liquids or gases, or to allow the injectionThe process of using pressure to force fluids down wells of fluids as for errors due to tilt of the sonic tool, to arrive at porosityMeasure for the amount of pore spaceSpace between rock or sediment grains that can contain fluids in a rock. No standard protocol is available for conversion from travel time to porosityMeasure for the amount of pore spaceSpace between rock or sediment grains that can contain fluids in a rock; there are many variations of the travel time/porosityMeasure for the amount of pore spaceSpace between rock or sediment grains that can contain fluids in a rock relationship.
Sonic logging is used usually for the determination of porosityMeasure for the amount of pore spaceSpace between rock or sediment grains that can contain fluids in a rock and permeabilityAbility to flow or transmit fluids through a porous solid such as rock in porous rock, the detection of fractures, and even for lithologyThe nature and composition of rocks characterisation (Paillet and White, 19821982 - FL Paillet, JE WhiteAcoustic modes of propagation in the borehole and their relationship to rock propertiessee more). The sonic velocity contrast between water and CO2Carbon dioxide is strong, so that this log(well) Records taken during or after the drilling of a well type can be used to assess changes in fluid as the CO2Carbon dioxide plumeDispersing volume of CO2Carbon dioxide-rich phase contained in target formationA body of rock of considerable extent with distinctive characteristics that allow geologists to map, describe, and name it moves past the wellboreThe physical hole that makes up the wellManmade hole drilled into the earth to produce liquids or gases, or to allow the injectionThe process of using pressure to force fluids down wells of fluids, it can be cased, open, or a combination of both; open means open for fluid migrationThe movement of fluids in reservoir rocks laterally between the wellbore and surrounding formations; cased means closing of the wellbore to avoid such migrationThe movement of fluids in reservoir rocks.
