Extensive slug-test experiments have been performed at the Hydrogeological Experimental Site (HES) of Poitiers in France, made up of moderately fractured limestones. All data are publicly available through the "H+" database, developed within the scope of the ERO program (French Environmental Research Observatory, http://hplus.ore.fr). Slug-test responses with high-frequency (> 0.12 Hz) oscillat...

Abstract Multi-cluster fracturing technology was often used in horizontal well reservoir reconstruction to achieve production increase, which also affected casing equivalent stress distribution. This paper focuses on multi-cluster and establishes a model line with the reality. The three-dimensional finite element of fracture-formation-cement sheath-casing proposed, influence cluster spacing num...

The MIC Series 550 camera combines cutting-edge technology with the latest production techniques to provide a class-leading feature set in an economical package. The MIC Series 550 range takes high quality surveillance to new levels of excellence. As a best-fit camera for virtually any security application, it can be installed in the harshest of environments. Thanks to its IP68-rated aluminum c...

Abstract This paper investigates cracking failure of the casing tube. There were longitudinal cracks in heavy oil thermal recovery well occurred an field. The fracture cause was analyzed by macrographic observation, chemical composition analysis, mechanical property test, metallographic scanning electron microscope (SEM) and residual stress calculation. results showed that crack failed originat...

We examine the basic assumptions underlying a scenario due to Kibble that is widely used to estimate the production of topological defects. We argue that one of the crucial assumptions, namely the geodesic rule, although completely valid for global defects, becomes ill defined for the case of gauged defects. We address the issues involved in formulating a suitable geodesic rule for this case an...

Objective: aim this study was production, storage and conversion artificial sage seeds. technology is placing explants capable regeneration into plants a protective casing. Methods: Apical axillary bud...

For processes such as water injection in deep geothermal production, heat transfer and fluid flow are coupled affect one another, which leads to numerous challenges wellbore structure safety. Due complicated structures, consisting of casing, cement sheaths, formations under high temperature, pressure, situ stress, the effects thermo-hydro-mechanical (THM) coupling crucial for instability contro...
