Un-locking the potential of such accumulations typically entail huge challenges posed by the extreme tightness of the reservoir rock
, target reservoir depths of up to 5,000 metres, and prevailing temperatures of around 180 degrees centigrade.
The methods can be used to evaluate the void space structure and the reservoir rock
type; to identify vugs, cavities, and fractures and their morphology, interconnectedness, and openness; and to differentiate fractures in terms of their importance to fluid filtering.
2]-brine-host reservoir rock
interactions, both for sandstones and carbonate rocks (Ross et al.
The reservoir rock
must be hydraulically fracked to enhance the productivity of the wells
TAGOGD is ideal for highly fractured reservoir rock
like that found in Qarn Alam, because the steam can be injected directly into the fractures, where it heats the surrounding rock and lowers the viscosity of the oil by a factor of up to 100 times.
Injection of surfactant to change properties of the reservoir rock
and fluid is one of enhanced oil extraction methods.
Oxford Instruments and partner Green Imaging Technologies have produced the P5 Cell for high pressure and temperature studies of petroleum reservoir rock
Fracking of reservoir rock
has been done for 40 years; fracking of source rocks is quite new, and it is this which has attracted the Greens' ire.
When it is injected dry it migrates through the reservoir rock
toward the production well, which is a point of low pressure, and it reacquires more condensate liquids (becomes wet again) as it moves through the saturated reservoir rocks
Note: If a seismic amplitude anomaly caused by the interface of a cap rock and a reservoir rock
is further supported by a so called AVO effect the chances for the presence of hydrocarbons in the reservoir rock
is often greatly increased.
Permeability is mechanical properties of reservoir rock
to know how easily fluids can flow through the rock) and possible drive mechanisms, it is possible to estimate the recovery factor, or what proportion of oil in place can be reasonably expected to be produced.
ecorpStim has successfully demonstrated the use of pure liquid propane for the stimulation, or fracturing, of hydrocarbon bearing reservoir rock
