sand production: a smart control framework for risk

sand production: a smart control framework for risk

2020-3-1 · Sand production is worldwide problem. It always has significant consequences on field development. Sand production from unconsolidated formation reservoir is a very challenging issue as it ends the production life of a reservoir and well. In the oil and gas industry, millions of dollars are spent yearly for the cleaning of sand

2000-12-1 · A well-accepted conceptual model for sand production was proposed by Morita et al. 7,8 In that model, sand production can either be triggered by compressive (shear) failure, induced by a combination of in-situ stress and drawdown, or by tensile failure, induced by the near-cavity pore pressure gradient. Compressive failure around a cylindrical

2015-6-1 · Transient sand production refers to a sand concentration declining with time under constant well production conditions. This phenomenon is frequently observed during clean-up after perforating or acidizing, after bean-up and after water breakthrough. Fig. 1, shows field example with a sand volume 1 L and decline period

2018-9-1 · Sand production is one of the most challenging problems during hydrate development. During hydrate development, the fluid produced by dissociation of the natural gas hydrates and deformation of the sediment skeleton in the dissociation process will generate excess pore pressure (Wu et al., 2012)

estimation of sand production rate using geomechanical

Sand production occurs in many oil fields across the world and it is especially common in the porous sediments. Sand production observed on the surface occurs as a series of three events that happen at downhole area: (1) formation failure, (2) sand erosion due to flow, and (3) sand

review of sand production prediction models

review of sand production prediction models

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 short period of time, resulting in

2018-2-17 · Sand production is the result of transportation of failed sand grains by the flow of reservoir fluids. Sand production problems have been the focus of major discussion in the industry for a long time (Geilikman et al. 1994; Santarelli et al. 1997; Grafutko and Nikolaevskii 1998; Stavropoulou et al. 1998; Papamichos and Malmanger 2001).Operationally, the production of sand is, in general

sand production prediction model for tight sandstone oil

sand production prediction model for tight sandstone oil

Tight oil is an important unconventional resource, and sand production is an inevitable challenge during the field development. In this paper, based on data from the Daqing oilfield in Songliao Basin, the sand production of the tight sandstone oil reservoir is studied from the perspective of seepage and in situ stress distribution. Based on the combination of the formation fluid seepage law

2018-12-31 · Large pressure pulses may cause wellbore-integrity problems such as sandface failure and sand production. We propose a new work flow to simulate water-hammer events, the resulting wellbore failure, and sand production in water injectors. On the basis of the results of this work flow, recommendations are made for wellbore design and shut-in
