... ABSTRACT: This study presents a new analytical model for power-law fluids and investigates its application in examining sand production. A xanthan gum (XG) based polymer solution is injected into the artificially made sandstone, with characteristics similar to the Kazakhstani oil field...

... ABSTRACT Sand production prediction is essential from the early stages of field development planning for well completion design and later for production management. Unconsolidated and weakly consolidated sandstones are prone to fail at low flowing bottom hole pressures during hydrocarbon...

... through feedback adjustment to increase the accuracy of target prediction. This work considers the similar lithology characteristics in the same block, the sand production profile of a single production well is first predicted by using empirical formulas and logging data, and further the logging data...

... ABSTRACT Sanding onset and sand production rate in non-isothermal conditions are of interest both for thermally related Enhanced Oi Recovery (EOR) and producing gas in gas hydrate bearing sediment processes for sand control and optimized production purposes. Thermal-hydraulic-mechanical...

... for any completion strategy is sand production across the life of a reservoir. If not managed appropriately, sand production will damage completion equipment and will lead to avoidable interventions or even premature well abandonment, both of which dramatically outweigh any upfront cost savings...

... ABSTRACT: Solids production is a complex physical process which is controlled by several factors including mechanical failure from in-situ stresses and hydrodynamic erosion from fluid flow. Mathematical and numerical models developed for the prediction of sand production, are usually based...

..., the triaxial compressive strength test and the reservoir strength profile prediction are carried out by using the reservoir core, and the water bubble strength test and the variation law of the reservoir core are also studied. Sand production prediction is carried out by using acoustic time difference method...

... Abstract Sand production is a complex phenomenon in oil wells where sand grains or chunks are detached from the formation during loading processes and transported to the wellbore by the flowing fluids, either oil, water or gas. This article presents a complete set of different laboratory tests...

... to prevent perforation failure and sand production. Ideally, the entire perforation volume is packed with proppant. However, there are cases of poor proppant packing jobs, which may leave perforations partially or completely unsupported. This increases the chances of perforation failure, sand production...

... 1D geomechanical model calibrated with field stress measurements and drilling data, well logs and core tests is used to assess the risk of sand production for field life duration for both existing and future wells. The field geomechanical model revealed subtle variations from the regional stress...

...-produce the sand to surface, requires an understanding of the mechanisms that cause sanding and the development of a field- and often reservoir-specific model to define the critical pressure conditions for sand production. The optimum sand control and completion decision is then selected based...

... of the heating area, its influence on the heating zone radius is not obvious, but the pressure field changes significantly near wellbore. The possibility of sand production increases quickly when production pressure difference is more than 3 MPa, production pressure is suggested to be generally controlled in 2.5...

... ABSTRACT: Sand production becomes a serious problem during the life of a well in the Zubair reservoir. In addition to the costs associated with lost production, workover operations, and the repair of electrical submersible pumps (ESP), field operators also have to manage the separation...

... ABSTRACT: Sand production is a challenging problem for production of oil and gas from unconsolidated sandstones, which may incur erosion and damage in the production pipe and surface of the equipment. Various methods, such as standalone sand screens, gravel packing and frac&pack have been...

... ABSTRACT: Sand production is a serious problem in heavy oil thermal recovery wells in the Bohai Bay, China. In this study, a comprehensive thermal-hydro-mechanical sand production model combining the processes of drilling, screen insertion, and gravel packing was established based...

... ABSTRACT: A three-phase flow large pre-packed Sand Retention Test (SRT) assembly was employed with different screen specifications for typical sand prints within McMurray Formation in Western Canada. Cumulative sand production and retained permeability are utilized as the sand control...

... and the plastic zone leads to solids production to the borehole. The model is also applicable to the description of transient sand production from perforation cavities. Reservoir Characterization Completion Installation and Operations elastic zone reservoir geomechanics Wellbore Design transient solid...

... ABSTRACT: Sand production has long been recognized as a major problem during the extraction of oil/gas from weak sandstone reservoirs. It has been well accepted that sand production is almost inevitable in poorly consolidated and unconsolidated sandstones due to the extremely low strength...

... in the permeability of the collapsed tunnel magnifies flow convergence skin significantly, especially in the lower shot densities and this added pressure drop can be very troubling. Results show in lower perforation densities higher pressure drawdowns may trigger sand production due to the tensile failure...
