... into the sandstone from the casing through the cement. A CT scanner was then used to detect any leakage channels or cracks in the cement that could compromise the integrity of the storage system. One end of the cemented annulus is connected to a Data Acquisition system via transducers to detect any leakage. This new...

... stabilization and leakage prevention in cementing is prominent. The safety density window of cementing is only about 0.03~0.10g/cm 3 . Based on the theory of wall shear stress, a set of narrow safe density window cementing technology suitable for Kuqa piedmont front is formed by finely evaluating leakage...

... ABSTRACT: The pressure-bearing capacity of the micro-fractured formation is low, and the leakage phenomenon is serious under the action of high-density drilling fluid. The pressure-bearing plugging can improve the pressure-bearing capacity of the formation that is vulnerable to leakage...

... ABSTRACT: A primary concern associated with the utilization of subsurface systems is that there may be pathways for fluid leakage from the resource storage, or disposal reservoir. Leakage of any fluid can contaminate groundwater, cause geo-environmental pollution, generate hazardous surface...

... ABSTRACT: The problem of coexistence of circulation leakage and blowout in drilling is difficult in drilling technology. Rapid and accurate identification of the location of the leakage layer is the key to taking reasonable measures to solve the problem. field parameter calculation method...

... time for gas storage and obtain faster gas injection-production application and economic effect. At the same time, this work can reduce the complex safety risks such as brine leakage, land subsidence and collapse caused by the long-term deformation of the cavern. In China, it has a long history of salt...

... ABSTRACT: Drilling mud loss is of crucial importance in drilling. Lost circulation will extend the well construction period, cause investment losses, and even cause serious downhole accidents. In the Mizhi block of Changqing Oilfield targeted by this research, serious leakage occurred in many...

... mechanisms that compromises wellbore integrity and can result in leakage of CO2 and other fluids. In this work, we developed an experimental system that enables the investigation of the initiation of a microannulus and fluid flow behavior along the interfacial pathways under in-situ conditions. The cement...

... and the associated governing processes have to be assessed in detail. In this contribution, we aim at improving our understanding of hydromechanical processes induced by dynamics of CO 2 leakage through intact shaly caprocks. To this end, we perform laboratory experiments on supercritical CO 2 injection...

ABSTRACT: In order to solve the problem that how far the horizontal extended-reach well can extend in carbonate formations, three kinds of extension limit prediction models in carbonate formations are established based on three types of leakage pressure, including fracturing leakage, fracture...

... that way for decades leading to concerns of oil and gas leakage. Current P&A practices in the GoM dictate that the well casing must be cut and buried beneath the sea floor (30 C.F.R. §250.1715). If a P&A ed well is leaking, the leakage would have to travel from the cut casing to the sea floor where...

This paper summarizes the past occurrences and several hundred others of varying severity (from...

... Abstract: Although methane leakage from oil and gas wells has received significant attention in the last thirty years, emission estimates still range between 1-9% of production. In more recent years methane leakage has been under scrutiny by industry, governments and the public. Methane...

... leakage through a leaking fault. Introduction In the past years, several novel approaches to reduce CO 2 emissions in the atmosphere have been proposed by the scientific community. Storing CO 2 in the subsurface is considered one of the most promising method to decrease the rate of increasing CO 2...

... Abstract Leakage to the atmosphere of a significant fraction of injected CO 2 would constitute a failure of a geological CO 2 storage project. We present a numerical model that simulates flow and transport of CO 2 into heterogeneous subsurface systems. The model, StoTran, is a flexible...
