Production tests in Canada and Japan were terminated partially because of excessive sand production in pilot wells. It is meaningful to carry out numerical investigations and sensitivity analyses to 网页A laboratory experiment was performed to better understand how sand production can increase heavy oil recovery. A horizontal sand pack with an orifice at one end modeled the production of oil and sand into a perforation in a vertical well. The sand pack was scanned using X-ray computed tomography (CT). The CT images revealed that a high-porosity 网页2020年1月2日 Sand production is a problem that affects hydrocarbon production from unconsolidated sandstone reservoirs. Several factors, such as the strength of the reservoir, its lithification and cementation and 网页1996年6月1日 @article{osti_250834, title = {Imaging of sand production in a horizontal sand pack by X-ray computed tomography}, author = {Tremblay, B and Sedgwick, G and Forshner, K}, abstractNote = {A laboratory experiment was performed to better understand how sand production can increase heavy oil recovery.

The problems resulting from sand influx include abrasion of downhole tubular/casing, subsurface safety valve and surface equipment; casing/tubing buckling, failure of casing or liners from removal of surrounding formation, compaction and erosion; and loss of 网页2021年5月27日 The sand production of the reservoir is mainly manifested as continuous sand production leading to blockage of near wells, and violent sand production is rare. X. Cheng, and Z. Wang, “A numerical model 网页1995年12月31日 A horizontal sand pack with an orifice at one end modeled the production of oil and sand into a perforation in a vertical well. The sand pack was scanned using X-ray computed tomography (CT). The CT images revealed that a high-porosity channel (wormhole) formed in the pack while sand was produced. 网页2012年12月1日 It is obvious from Fig. 8 that the horizontal boreholes have less potential for sand production than the vertical and deviated boreholes in all directions. As Fig. 8 shows, in this case the best direction is a horizontal borehole close to the maximum horizontal stress direction same as Wirput and Zoback [13], [14] studies. 网页2013年1月9日 Sand production in oil and gas wells can occur if fluid flow exceeds a certain threshold governed by factors such as consistency of the reservoir rock, stress state and the type of completion used around the well. The amount of solids can be less than a few grams per cubic meter of reservoir fluid, posing only minor problems, or a substantial amount 网页A laboratory experiment was performed to better understand how sand production can increase heavy oil recovery.

A horizontal sand pack with an 网页Sand production is one of the main problems restricting the safe, efficient and sustainable exploitation of marine natural gas hydrate. To explore the sand-control effects of gravel packing, experiments that simulate hydrate extraction in the water-rich environment were conducted with designed hydrate synthesis and exploitation devices. Three sand control 网页1995年12月31日 A horizontal sand pack with an orifice at one end modeled the production of oil and sand into a perforation in a vertical well. The sand pack was scanned using X-ray computed tomography (CT). The CT images revealed that a high-porosity channel (wormhole) formed in the pack while sand was produced. 网页Sand production in oil and gas wells can occur if fluid flow exceeds a certain threshold governed by factors such as consistency of the reservoir rock, stress state and the type of completion used around the well. The amount of solids can be less than a few grams per cubic meter of reservoir fluid, posing only minor problems, or a substantial amount over a 网页2022年3月22日 Sand production is a crucial geotechnical issue for safe and efficient gas recovery from natural gas hydrate (NGH) reservoirs. Although the same gas production method of depressurization was chosen for the production trials in the Nankai Trough and the Northern South China Sea, their sand production behaviors differed greatly due to 网页2019年3月27日 In an unconsolidated sandstone reservoir of a deepwater gas field, due to the reduction of the rock compaction by deepwater, sand production is more likely to occur in the reservoir during production under certain production pressure differences. Therefore, it is important to accurately control the production pressure difference. A theoretical analysis 网页2021年5月25日 With the increase in azimuth angle, its influence on the CDP of sand production in different perforating directions decreases gradually.
