Contributors in Oilfield

Oilfield

In cyclic steam injection, the second phase between the steam-injection phase and the production phase. During the soak phase, the well is shut in for several days to allow uniform heat distribution ...

probe

Oil & gas; Oilfield

In electromagnetic methods, to measure the variation of a property versus depth, including electrical, electromagnetic and magnetotelluric properties. Probing differs from profiling in that the goal ...

mobility buffer

Oil & gas; Oilfield

In chemical flooding, a fluid stage, normally water thickened with a polymer, pumped between the micellar or alkaline chemical solution and the final water injection. Mobility buffers are prepared ...

stroke

Oil & gas; Oilfield

In a sucker-rod pump, one complete round of the polished rod (surface stroke). On each stroke, a fixed volume of liquid is lifted. This volume is related to the cross-sectional area of the pump and ...

pore throat

Oil & gas; Oilfield

In an intergranular rock, the small pore space at the point where two grains meet, which connects two larger pore volumes. The number, size and distribution of the pore throats control many of the ...

traveling valve

Oil & gas; Oilfield

In a subsurface sucker-rod pump, the valve that closes the barrel chamber allowing the trapped fluid to be lifted in the upstroke of the pump. This valve is similar in configuration to the standing ...

bypass velocity

Oil & gas; Oilfield

In a spinner flowmeter, the theoretical minimum fluid velocity required to initiate spinner rotation, assuming the spinner response is linear. In this sense, it is synonymous with threshold velocity. ...
