Sand production from V-shaped breakout changes the wellbore shape from circle to ellipse. 4. The boundary stress plays a major role in sand production through sandstone degradation. However, less sanding occurs at higher boundary effective stress but considerably lower boundary pressure due to ineffective removal of the degraded …
50% of existing wells require sand control or sand management throughout their lifetime in the world [].During the production of high-production gas wells [] in offshore sparse sandstone blocks, the formation sand will be carried to the surface by gas & oil flow, and some sand particles will be deposited at the separator [] and pipeline [], …
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 …
The sandstone reservoir rock failure during production may lead to sand production issues and may impact the economics of field development strategy, especially deep-water operation.
In 2023, there was a total of 130 million metric tons of sand and gravel produced in the United States for industrial purposes. This was the world's largest industrial sand and gravel production ...
Until better prediction techniques are available, the best way of determining the need for sand control in a particular well is to perform an extended production test …
Geomechanics of Sand Production and Control delivers a convenient resource for both academia and professionals to gain understanding and results surrounding sand production. Packed with rock mechanic fundamentals and field case studies, this reference offers theoretical knowledge, field and laboratory data, and operational methodologies.
This paper presents three case studies to provide well engineers with guidelines to understanding the principles and overall workflow involved in sand production …
No sand production may occur with small pressure drawdown around the well, whereas excessive drawdown can cause the formation to fail and produce sand at unacceptable levels. The amount of pressure drawdown is normally associated with the formation permeability and the viscosity of the produced fluids. Low viscosity fluids, such …
The silty-clay flow and massive sand production caused by sediment deformation were observed in the process of depressurization in hydrate silty-clay reservoir. Moreover, a mud cake around the wellbore may be formed due to the decrease of water velocity [11]. High initial hydrate saturation can cause high sand production rate and …
Construction sand and gravel, one of the most accessible natural resources and a major basic raw material, is used mostly by the construction industry. Despite the low unit value of its basic products, the construction sand and gravel industry is a major contributor to and an indicator of the economic well-being of the Nation.
Sand production and the sand control technique selected to mitigate or eliminate it can have a critical influence on the performance of horizontal wells in gas storage reservoirs. A completion ...
The sand failure pattern is found to largely differ from that of a sandstone reservoir, whereas fractures, wormholes, and fluidized channels are successively developed along with a large scale of sand production and inlet pressure variation. Followed is a steady flow state with a stable inlet pressure without noticeable sand failure.
Sand production can occur without sand control measures, disrupting oil and gas production, corrosion of underground equipment, casing damage, and well abandonment [17]. It is reported that residual mouth bar sandstone will likely form in sandy channel bodies associated with high natural gas deposits [18]. Some factors leading to …
Sand production is a common problem in the development of oil and gas fields. A large amount of sand production will lead to formation plugging, production reduction or even shutdown of oil and gas wells. Therefore, it is necessary to understand the mechanism of sand production and its hazards, and do a good job in prevention.
It reached 38.2 m³/day on the 6th day after the well was opened. In the following 30 days, the water production rate dropped to 44.43 m³/day and the sand production rate dropped to 3.95 m³/day. The water production rate and the sand production rate drop by 4.01 m³/day and 0.21 m³/day, respectively, at the 365-day …
1. Introduction. Sand production has been a serious concern for the oil and gas industry for decades. The costs associated with sand production are estimated to run into billions of dollars on an annual basis (Orourke et al., 2004).Sand production refers to the transport of solid particles, in particular sand flakes and individual grains, in oil …
Sand production in unconsolidated reservoirs has become a cause of concern for production engineers. Issues with sand production include increased wellbore instability and surface subsidence ...
Sand production can be considered one of the major challenges in the petroleum production industry, causing severe operational issues. This study introduces …
Achieving maximum well productivity without excessive sand production or plugging requires sand control that depends on the type of the reservoir and …
The sand carrying fluid of heavy oil cold production well is used to carry quartz sand to the depth of formation, near well zone and annulus, and form a high conductivity sand blocking belt with screen pipe to form heavy oil cold production sand control technology, which can improve the oil well production capacity of loose sandstone heavy oil ...
Well sand production can be broadly divided into two stages: the first stage is the change from skeletal sand to loose sand, which is a necessary condition leading to …
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 can plug tubing, casing, flowlines and surface vessels. It can erode equipment that leads to loss of well control or unwanted fluid emissions.
Production increase Generally, concerning the amount of sand production in the well, sand production is divided into 3 states: unstable, stable and catastrophic [1].
How to Control Sand Production in Oil and Gas. Sand is one of the many impurities that contaminate oil recovered from natural reservoirs. Sand is typically produced thanks to the degradation effects of oil recovery like pumping pressures, level of particle consolidation and the level of viscosity of fluids flowing through the production well.
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 …
In this paper the sand production factors and their effects are presented where the emphasis is given towards the sand prediction to determine the probability of …
Sand control refers to managing/minimizing sand and fine production during petroleum production.Sand and fine produced with oil and gas can cause erosion and wear of production facilities/equipments, resulting in production downtime, expensive repairs, and potentially loss of containment (serious safety risk).
