The production of carbonate debris was observed in a 900m horizontal well completed as barefoot in Arab limestone...

... ABSTRACT: The coupling method of CFD-DEM is used to simulate the transportation and steering blocking process of temporary plugging ball in horizontal wells, to investigate the influence of the position of temporary plugging ball, injection flow rate and injection displacement on the blocking...

... ABSTRACT: Horizontal wells have been frequently used in many oil reservoirs, which has significant advantages in improving oil development efficiency. During horizontal well drilling, the cuttings can easily accumulate in the wellbore to form a cuttings bed at the bottom. The formed cuttings...

INTRODUCTION The multi-section and multi-cluster hydraulic fracturing technique in horizontal wells is a crucial...

... processes during RF heating in horizontal wells at the operational level. 1. INTRODUCTION As one of non-conventional hydrocarbon resources, heavy oil reservoirs are widely distributed in the world. Nevertheless, high viscosity prevents the rich resources from being large-scale exploited (Hassanzadeh...

..., distance between them, and angle between the branch and the main horizontal well. This study compared vertical wells to a fishbone well using numerical simulation of real field data in Algeria. The suggested fishbone well design (8 branches, 800m length, 200m distance between branches, and 65° angle...

... ABSTRACT At present, with the continuous development of unconventional oil and gas exploration and development, horizontal wells, as an important means of unconventional oil and gas exploitation, have attracted much attention from drilling teams and oil field companies. However, the cost...

... of a horizontal well, from dynamic fracture propagation to long term pressure depletion. High levels of mesh refinement are used to obtain very fine meshes in the near wellbore region to simulate the deformation of the rock and the casing along the wellbore. Axial and radial strain is obtained as a function...

... ABSTRACT Deep shale gas has become an important alternative resource for shale gas development in China, and the number of horizontal wells drilled is increasing year by year. However, the rate of penetration, bottom hole temperature and leakage in horizontal section are seriously restricted...

... field and pressure distribution of fractured horizontal wells. In the 1990s, many scholars studied the unstable pressure characteristics of fractured horizontal wells produced under the conditions of infinite conductivity and finite conductivity vertical fractures (Kuchuk and Habusky, 1994).

... and worldwide unconventional oil and gas wells are pushing the technical limits of existing drilling tools and technology to drill longer horizontal and extended reach wells (ERW), with ERW becoming the mainstream technology. For example, horizontal wells in the United States averaged about 10,000 feet...

... to create new and old fractures depends on the updated reservoir properties. Using a loose coupled technique, the in-situ stress prior to refracturing was computed and local dynamic stress change can be found along the horizontal well lateral stage. Numerical simulations indicate fluid injection volume...
