Which statement correctly differentiates hydraulic fracturing from compression?
A. Hydraulic fracturing increases pressure, while compression increases permeability
B. Hydraulic fracturing improves gas flow in the reservoir, while compression assists flow at the surface
C. Hydraulic fracturing is applied at late-stage production, while compression is used at early stage
D. Hydraulic fracturing replaces the need for primary recovery
Hydraulic fracturing mainly improves natural gas production by:
A. Increasing reservoir pressure
B. Creating additional flow paths in low-permeability rock
C. Reducing the viscosity of natural gas
D. Separating heavy hydrocarbons from methane
Why is the compressibility factor important in engineering calculations?
A. To calculate molecular weight
B. To determine reaction rate
C. To predict actual gas volume accurate
D. To measure gas temperature
choose the correct statements:
. Recoverable gas is always equal to the total Gas in Place (GIP), regardless of reservoir conditions.
. fraction of GIP is recoverable depending on reservoir permeability and pressure
. Safety and environmental constraints is one of the factor fraction of GIP is recoverable
Recoverable reserves depend only on the thickness of the reservoir and not on pressure, permeability, or technology
