... that affected the velocity of a bubble rising in an annulus. They concluded that both bubble-rise velocity and bubble fragmentation significantly affect the annular pressures encountered during well-control operations. The velocity of expansion is equal to the difference in velocity between the leading...

... processes. This paper discusses the possibility of coagulating these two technologies in an attempt to achieve maximum economic and productive efficiency. The system consists of the usual assembly for drilling with casing, which uses the top drive mechanism, and an expansion cone (mandrel) installed above...

... often key factors are manipulated such that perceived reliability actually does not represent reality. The success of any solid expandable installation depends on downhole conditions and that of the solid expandable tubular surviving the expansion process. This total expansion must then undergo...

...Scoping vs. Conventional Expansion Deployment for scoping is similar to conventional expansion but there are certain distinctions: Abstract A method called "scoping" for installing solid expandable tubular (SET) drilling liners across pressure-depleted zones has been developed...

... of the casing, and all the casing, tubing and annulus in the well are together forming a system that should be resolved simultaneous. This is simple to resolved utilizing computer algorithms although the method can be performed directly in three steps: Calculus of the thermal expansion Fluids Pressure...

... contain less than 8 and 3 %C 3 A respectively. Under certain conditions, sulfate ions will chemically combine withtricalcium aluminate giving rise to an expansive reaction that can cause cementdistress. This process depends on cement permeability and environmenttemperature. Several research studies...

... is constant. As a result, there is a progressive increase in oil recovery due to internal expansion of the gas bubbles. This study aims to explain the peculiar behavior of the reservoir making some adjustment on material balance equations in order to find equations of Drive Depletion Index (DDI) caused...

... and steel production, power generation, and in the transportation and commercial sectors. Even greater demand is expected with expansions in these and other areas, e.g. aluminum and gas to liquids processing.

... activation and growth of bubbles. Site activation occurs when the pressure of the liquid allows the release of trapped gas at the solid surface crevices. Growth takes place by bubble expansion that drives the liquid out of the system. Two pressure boundary conditions for the network are considered. The first...
