Choose the correct answer:

An IPR for an undersaturated hydrocarbon reservoir is linear because

The fluid is fully compressible

Flow is single phase, incompressible

That is the law for oil reservoirs

Skin is:

A dimensionless number added to the Darcy flow equation to account for an additional pressure drop

A function of the damaged zone around the well, i$.$e$.f(r_p,K)$

Related to the effective wellbore radius

All of the above

None of the above

Given the following:

bpd

This curve identifies an IPR for a well at time $t=0$ years, which $s=0$ and at a later time $t=12$ years, with $s=10.$ If the well has permeability $k>100$ md$,$ this IPR most likely

Transient

Steady state

Pseudosteady state
