Sand Production is the migration of the formation sand induced by the flow of reservoir fluids. It is initiated when the rocks around the perforations fail and the fluids thrust the loose grains into the borehole. It takes place when the reservoir fluid flow outpaces an ...

Mitigation Of Sand Production In Sandstone Reservoir Using

Mar 14, 2019 · Alternately, as the reservoir pore fluids squeeze into the well or perforation cavities, the pressure gradient can be relatively very high in the near-well and perforation regions, so some grains in the mechanically failed area may be carried by the pore fluids and transported to the production well, with the result that some amount of sand ...

Sand Production Management for Oil and Gas Reservoirs

Sand production is a serious problem in oil and gas reservoirs worldwide. It can drastically affect production rates. The adoption of a sand management strategy is crucial for prolonging economic reservoir development for sand producing reservoirs. Significant gains in production (acceleration) and reserves (IOR) can be resulted from the pursuance of sand management in these fields. Such a ...

Sand production from reservoir formations can take place if the reservoir fluid flow exceeds a certain threshold influenced via factors for instance stress state, consistency of the formation grain and the completion strategy used around the well.

Search Petrowiki: Predicting sand production

Predicting whether a well will produce fluids without producing sand has been the goal of many completion engineers and research projects. There are a number of analytical techniques and guidelines to assist in determining if sand control is necessary, but no technique has proven to be universally acceptable or completely accurate.

Heavy oil production

One variation of the cold production method is called Cold Heavy Oil Production with Sand (CHOPS). CHOPS creates a wormhole or void where oil gets pulled from the surrounding rocks towards the wellbore. These methods are termed cold production, since they are used at reservoir ambient temperature. When natural lift pressure does not generate ...

Introduction to IPR and VLP

May 11, 2017 · The productivity of the well depends on an efficient use of the compressional energy available in the reservoir allowing the reservoir fluids to flow toward the production separator. As an introduction to IPR and VLP, this article will introduce two key relationships (IPR and VLP) used in the design of the production system.


4 PHYSICAL PROCESSES IN CHOPS PRODUCTION 4.1 Reservoir Mechanisms Maintaining Sand Influx 4.1.1 Energy Sources and Stresses In the CHOPS process, a set of driving forces is responsible for the continued sand influx that

Sand Production Prediction

The user can check the influence of planned oil production strategies on the amount of expected sand, and thus tailor both draw-down and depletion scenarios so as to minimise sand production during the whole expected life of the reservoir. SandPredictor uses a semi-empirical sand production model developed in the Sand Production JIP.


of sand influx causes the well to die and/or choke. This is the worst case of sand production and it occurs when the reservoir fluids are excessively produced. 1.2 Sand production prediction There are many sophisticated geomechanics software which can be used to pre-dict sand production over long range of reservoir conditions and time. However,

Sand control completions using flux analysis

Many models and predictive techniques make this determination based on rock strength measurements. Depletion forces also weaken the sand matrix, resulting in a well capable of producing sand free at high drawdowns early in well life, but failing later in life after the reservoir is partially depleted with the same or smaller drawdown.

Sand Management System - Forum Energy Technologies, Inc

Many sand control completions use sand screens to filter solids at the end of the production strings. Variable grain sizes within a reservoir mean that even a carefully selected screen can only partially filter most of the grains. Sand screens quickly plug and erode, requiring lengthy sections downhole to ensure adequate performance.

Pressure drawdown & Skin Factor

Oct 31, 2017 · NB: Reservoir conditions, such as the tendency to produce sand, may limit the drawdown that may be safely applied during production before damage or unwanted sand production occurs. The notion of Formation damage (Skin Factor): As per the previous figure, a new term is introduced, ∆P s or delta P skin. The term S stands for Skin Factor. Skin ...

Influence of Sand Production in an Unconsolidated Sandstone Reservoir

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 ...
