Minimal sand production; Low production rates; Economically viable well service; Rate restriction. Restricting the well's flow rate to a level that reduces sand production is a method used occasionally. The point of the procedure is to sequentially reduce or increase the flow rate until an acceptable value of sand production is achieved.
This book investigates sand production problems in the development of unconsolidated sand reservoirs and suggests novel technical solutions and improvements to sand management issues. This book is divided into six chapters: (1) geologic characteristics of unconsolidated sand heavy oil reservoirs and concept of sand …
sand production. 1. n. [Well Completions] The migration of formation sand caused by the flow of reservoir fluids. The production of sand is generally undesirable since it can restrict productivity, erode completion components, impede wellbore access, interfere with the operation of downhole equipment, and present significant disposal ...

The sand production increases as the water cut increasing. This incidence is clarified via two mechanisms. When the sandstone formation is water-wet, some of particle-to-particle cohesiveness is provided via the surface tension of connate water that is …
Sand production behavior is also studied in laboratories. Oyama et al. (2010) found that the dominant driving force of sand production was water flow rather than gas flow generated by dissociation, and the amount of sand production was influenced by the velocity of the water flow. Jung et al. (2012) suggested that fine particle migration may be …
Sand production may be inevitable in many fields that have a relatively low formation strength. Sand erosion and settling predictions and sand monitoring are important elements of any effective sand production management strategy. Sand erosion predictions are used to establish tolerable sand production rates, and, thus, well …
Whether it's prototyping, the production of spare parts or agile industrial series production. With Binder Jetting 3D sand printers, and the tool-less production of 3D printed sand molds and cores for classic metal casting processes, we are opening up new horizons for the foundry industry. Without restrictions in individualization, lightweight …
1. Introduction. A significant proportion of the world oil and gas reserves is contained in weakly consolidated sandstone reservoirs and hence is prone to sand production. …
A common technique used for determining whether sand control is required in a given geologic area is to correlate incidences of sand production …
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 …
Canada and Venezuela have mined tar sands for years — much of the bulk imported petroleum in the U.S. comes from the sands of northeastern Alberta. But this is the first tar sands mine in the ...
BP Neural Network (BPNN) is a widely used deep learning algorithm, and strengthens the accuracy of developing training models 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 …
Migration of sand within the reservoir can present major obstacles to well production through reduced production rates, sand bridging, erosion of equipment, and sand disposal and removal. Our sand control services begin with an in-depth analysis of the reservoir and well conditions. Based on your unique needs, we then provide specialized ...
Sand production is conventionally associated with diverse heterogeneous formations, especially poorly consolidated formations. Scrutinizing fluid flow rates at different orientations of perforations is a valuable analysis in controlling the sand production. This study was conducted to examine the case of sand production in a few development ...
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 and disposal of the sand produced with the oil. …
According to the movement rule of the sand in the flow, Sand in the pipeline making the collision with the pipe at the elbow, producing a sound signal, which is regarded as sand production signal.
Sand production index (B) method. Results from this method show a range of values (Table 6) with an average of 1.88 × 10 12 psi and values ranging from 0.99 to 2.24 × 10 12 psi 2. The increase in the sand production index (B) indicates that the rock has a high elastic modulus, making it stiffer and more stable.
Production engineers in oil and gas utilize sand production and sand control equipment in many completion methods, with a growing interest to expand these methods in wells for CO2 sequestration and geothermal areas, but knowledge on these methods is fragmented and lacks a bridge to support energy transition. This book provides the coverage ...
Facebook1Tweet0Pin0LinkedIn0 Sand control is a method to control sand production into a wellbore. This is common requirement for several oil and gas producing wells around the world. There are two …
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 …
Due to its significant impact to reservoir productivity and production efficiency, sand production has been widely researched in recent years. This paper …
Abstract. Production of the sand becomes a significant problem throughout the life of wells, especially in poorly consolidated reservoirs. This issue frequently leads to tube buckling and abrasion ...
Sand production with reservoir fluid is a well known problem in many parts of the world. Sand production in a well causes restricted production or complete loss of production due to sanding of well bore. There are several methods of sand control but most of the technologies require heavy hardware and tools thus making the cost of new well very ...
Sand production can be considered one of the major challenges in the petroleum production industry, causing severe operational issues. This study introduces various methods to control and prevent sand production in petroleum wells and evaluates their advantages and performance in tabular form. The use of chemical procedures is …
2018. Sand production due to result of unconsolidated grains in wellbore formations, as lead to many adverse effect, such as plugging, accumulation in surface equipment, increase in skin and tubing roughness. Sensitivity analysis using PROSPER software was run on different well parameters, (tubing roughness, skin) and under free gas effect for ...
Abstract and Figures. Due to the current global oil price, the sand production is considered undesirable product and the control of sand production is considered as one of the main concerns of ...
