A simple, mechanistically based scheme for the calculation of the pressure drop in wells producing oil and gas in the single-phase liquid, bubble and slug flow patterns is described and checked with independent field data. The scheme is based on an identification of the flow pattern through a ...

A pressure bleed-off module for an oil well includes: an inlet receiving fluid from an annulus vent of the well; an outlet sending the received fluid to a kill valve of the well; and two paths coupled in parallel between the inlet and the outlet. Each path channels a flow of the ...
When gas is in motion inside a pipe or an annulus, frictional pressure drops could become very large. The equation that can be used to calculate the total pressure drop in gas flow is derived from the first and second laws of thermodynamics. The first law of thermodynamics applied to a dif...
A downhole tool for pressure testing of oil and gas wells comprises a generally tubular main tool (1), which is provided with an internal passage (2) and is arranged for attachment at the lower end of a drill pipe string. The main tool (1) is on its outside provided with an inflatabl...

PRESSURE DROPRECURRENT RATIOThe main principles of formation of static pressure in gas and gas-condensate wells, in which distribution of content and properties of phases with depth was taken into consideration, have been studied. An analytical basis and methods of calculation of formation pressure ...
Two Bourdon tubes, exposed at their open end to the pressure in a well, are fixed at that end to a common block. The closed ends are bent over and tension a vibrating string which is excited by an electromagnet. The tension which varies in proportion to the pressure changes the ...
