2022年2月1日 Sand production can occur during hydrocarbon production, which poses a significant issue for continued oil and gas production. The existing finite element simulation of sand production usually assumes that the formation rock is a homogeneous medium.However, the actual formation is usually a heterogeneous natural material;
2015年6月1日 Sand production is a serious problem widely existing in oil/gas production. 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
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
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 the
2023年1月17日 In the process of drilling and producing oil in unconsolidated sandstone reservoir, the stress and pore pressure around the oil production cavity will be redistributed, which will cause serious
2002年10月1日 Having identified when the onset of sanding occurs, recent research efforts have focused on determining the rate at which sand will be produced once these thresholds are exceeded. In this paper a ...
Sand, the main ingredient of cement, glass, and asphalt, is being mined for urban development and global production at a pace that exceeds natural renewal. Yet research on the sustainability of sand mining has concentrated on extraction rates and socioecological impacts in rivers and coastlines. The potential of active volcanoes to
2022年10月28日 The sand production damage of the unconsolidated sandstone core samples increased with an increase in injection pressure. The injection pressure increased from 5 to 25 MPa, and the sand production damage of the overall pore throat, smaller pore throat, and larger pore throat was 2.55–19.98%, 2.07–12.56%, and 0.13–10.41%,
2022年4月25日 In Oman, petroleum-contaminated sand from a well had an oil content of 23% with traces of cadmium and lead (Taha et al. 2001 ). Similarly, a few sand samples recovered from oil productions in Brazil were found to leach mercury amongst other metals such as lead, cadmium, barium, and chromium (Pinheiro and Holanda 2013; Souza et al.
Sand production problem during gas hydrate exploitation seriously restricts its safe, efficient and controllable exploitation and industrialization process.It becomes one of the bottlenecks which should be solved urgently.The typical hydrate reservoirs in the South China Sea are clay-rich silt formation which cause more prominent contradiction between
2022年5月10日 The apparent density of the sand production sample after hydraulic fracturing treatment (2.66-2.67 g/cm 3) is higher than that of the downhole core sample (2.25-2.45 g/cm 3), the quartz content of the sand production sample after hydraulic fracturing treatment (99-100%) is much higher than that of the downhole rock core sand
2022年1月6日 sand production and the challenges faced by natural gas production in China in the light of the sand production that has been carried out at home and abroad. Huang et al. [24] compared the characteristics of sand production from hydrate reservoirs and conventional oil and gas reservoirs, summarized the research method of sand
2021年3月16日 16.03.2021. Sand Production in Gas Storage Fields. Sand production in gas storage fields is a well-known issue. Due to the high-volume retrieval of gas from the formations, even small concentrations of sand at high velocities can result in damage to equipment facilities and even total erosion of pipes at critical points.
2004年9月1日 Request PDF Sand Production Prediction: A New Set of Criteria for Modeling Based on Large-Scale Transient Experiments and Numerical Investigation This paper introduces a predictive tool that ...
2010年6月27日 ABSTRACT:. The sand production rate in three outcrop sandstones under various saturation and flow fluids is investigated to reveal the potential contribution of three different mechanisms on sand production rate and initiation. The mechanisms that are investigated are strength water weakening, capillary cohesion in the failed zone and
This paper demonstrates the applicability of machine learning algorithms in sand production problems with natural gas hydrate (NGH)-bearing sands, which have been regarded as a grave concern for commercialization. The sanding problem hinders the commercial exploration of NGH reservoirs. The common sand production prediction

2022年2月3日 In oil and gas industry, sand can be carried with oil and gas, when producing from unconsolidated sandstone reservoirs. The existence of sand particles with fluids flow can lead to severe damages to production system’s components. Therefore, sand control techniques are needed to prevent potential damages. Standalone sand
1994年11月1日 Sand production prediction is important because of the safety, environmental, and operational concerns involved when produced sand particles fill and plug the wellbore, erode downhole and surface equipment, and increase operating expense. Currently, no method of sand production prediction is universally regarded as accurate
Production enhancement from sand management philosophy. S. Asa, H. Kjørholt, +1 author. Spe Statoil Asa. Published 2005. Geology. Statfjord and Gullfaks are "Brown" fields operated by Statoil in the Tampen area of the North Sea. The production from these fields is characterized by large volumes of water and increasing sanding tendencies.
