Finite Element Based Dynamic Analysis of a Device in Coiled Tubing Drilling
The need for flexibility in operation and minimized drill time has necessitated the extended use of coiled tubing drilling technology. Among others, the technology eliminates the time to connect drill pipes and thus enables a quick retraction and insertion of different tools in the well. On the other hand, the complexity of the operating conditions makes the task of testing functionality of com...
متن کاملBiocide-mediated corrosion of coiled tubing
Coiled tubing corrosion was investigated for 16 field water samples (S5 to S20) from a Canadian shale gas field. Weight loss corrosion rates of carbon steel beads incubated with these field water samples averaged 0.2 mm/yr, but injection water sample S19 had 1.25±0.07 mm/yr. S19 had a most probable number of zero acid-producing bacteria and incubation of S19 with carbon steel beads or coupons d...
متن کاملPressure Loss Estimation of Three-Phase Flow in Inclined Annuli for Underbalanced Drilling Condition using Artificial Intelligence
Underbalanced drilling as multiphase flow is done in oil drilling operation in low pressure reservoir or highly depleted mature reservoir. Correct determination of the pressure loss of three phase fluids in drilling annulus is essential in determination of hydraulic horsepower requirements during drilling operations. In this paper the pressure loss of solid-gas-liquid three-phase fluids flow in...

15 صفحه اولLoss of lipid to plastic tubing.
14C-labeled oleic acid and (3)H-labeled monoether in a bile salt solution were perfused through three types of plastic tubing. Large proportions of lipid were lost to the walls of silicone rubber and polyvinyl chloride tubes. The major portion of the lipid lost was recoverable only when chloroform-methanol was perfused through the tubings. On the other hand, very little lipid was lost to the wa...
