A Flashcards
The pressure in the pore space that caused from underlying rock is called ?
(Overburden pressure)
The process of dispersed water by clay minerals is called?
(Clay Swelling)
A spontaneous flow of fluids from more dilute solution to a more concentrated solution across a semi-permeabel bed membrane is called?
(Osmosis)
A test that carried out to the point where the formation leaks off called ?
(Leak off test)
is it true that fracture gradien is lowest at the last casing shoe than the previous casing shoe?
(not true,because it depend on rocks lithology pp,ov,rock type)
the mud hydrostatic pressure greater than fluids pressure in the fomation is called?
(overbalanced or geopressure)
the drilling technology that used hydrostatic pressure less than formation fluids pressure is called?
(underbalanced drilling)
the drilling technology that let the drilling fluids loss to the formation without causing lost circulation and used viscous and weighted fluids that injected from annulus to manage pressure while drilling ahead is called?
(pressure mud cap drilling)
fluids influx from formation to the wellbore, is called?
(kick)
Pressure – depth profile accros the reservoir that could constructing fluid-fluid contact its called ?
(Repeat Formation Test ) RFT
The formation test that used drillpipe to produced and analyse fluids and pressure responds its called ?
(DST)
The maximum knowing depth of hydrocarbon (oil/ gas) bearing zone called?
(LKO / LKG)
The properties of reservoir fluids that determine volume of fluids in the reservoir compared to the standard condition ?
FVF
The water saturation that immobile in the pore space called ?
(Swc or Swirr)
Saturated core with 100 % wetting phase, then core is injected with non wetting phase, the procces is called?
(Drainage)
Who discovered the experiment that permeability measurment is made with air rather than liquid as flowing fluids ?
(Klinkenberg Effect)
The upper limit of the reservoir thickness that contributes to oil recovery is called ?
(Net Pay)
The presssure at which solution gas evolved from crude oil solution is called?
(bubble point pressure)
Is it true for gasses has compressibility less than liquid compressibility ?
(False)
The permeability of a rock sample that was 100% saturated with fluids is called ?
(abs. K)
the abillity of fluids to spread over the rock surface is called ?
(wettability)
