The present investigations on sealability evaluation for tubing and casing premium connections depend the FEM with testing. This paper proposed a theoretical model to evaluate of sphere-type connection based make-up torque, which combines Hertz contact pressure von Mises yield criterion calculating elastic–plastic distribution sealing interface adopts gas obtained from Murtagian’s experimental ...

Several features make Java an attractive choice for scientific applications. In order to gauge the applicability of Java to Computational Fluid Dynamics (CFD), we have implemented the NAS Parallel Benchmarks in Java. The performance and sealability of the benchmarks point out the areas where improvement in Java compiler technology and in Java thread implementation would position Java closer to ...

Abstract In this experimental study, two different cementitious materials, including (i) a class of expansive cement currently used for plug and abandonment (P&A) operations (ii) non-cement-based naturally occurring rock, known as geopolymer, are selected to examine the hydraulic bond strength shear strength. Clean machined steel rusty corroded were represent casing. The test samples cured ...

Chitosan with sandalwood (Santalum album) essential oil (SEO) using malic acid as solvent were evaluated an active packaging film. It was applied sachet to butter packaging. The effects of SEO concentration (0.5 %, 1 % and 2 v/v) on chitosan film properties studied by measuring the equilibrium moisture content, solubility, water vapor permeability (WVP), mechanical, optical, heat sealability, a...

Summary In oil and gas geothermal well construction, a cementitious material is pumped in the wellbore to provide zonal isolation support casing during life cycle of well. Thus, barrier materials must be durable terms chemical mechanical properties have compatibility with pipe. The complex region casing-cement interface considered key parameter fulfill long-term isolation. This chemically stabl...

OBJECTIVES The aim of this study was to evaluate the apical sealability of Fillapex®, endo-CPM-Sealer® and Sealapex®. MATERIAL AND METHODS Ninety-four freshly extracted single-rooted teeth were selected and decoronated. All teeth were radiographed to confirm the existence of a single and straight root canal, which was prepared using Protaper Universal and 2.5% sodium hypochlorite. The teeth w...

Ni/Au plated finishes used on thick-film metallized multilayer ceramic packages for integrated circuits must meet functional requirements such as bondability, sealability, and solderability. Their ability to do so is dependent, among other things, upon the ability of the Au deposit to inhibit the grain boundary diffusion and subsequent surface oxidation of Ni. In this study, the relationship be...
