Sand production: A smart control framework for risk ...

2020-3-1  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. Sand production also restricts the production flow rate, hence causing huge economical loss.

Fluid Flow and Sand Production in Heavy-Oil Reservoirs ...

Extensive sand production modifies the reservoir in the vicinity of the casing, but laboratory studies have shown that no amount of sand remolding or fines removal would increase the permeability to the extent apparently observed in pressure analysis. It is more likely that the laboratory-determined core permeabilities are overestimates of the ...

Sand Production - an overview ScienceDirect Topics

The internal causes of sand production from the reservoir are the stress state of borehole wall rock and the tensile strength of rock (affected chiefly by consolidation strength of rock), whereas external causes are the producing pressure drawdown value and the change in reservoir fluid pressure.

2019-6-1  Sand production is a crucial problem during the process of extracting natural gas from hydrate reservoirs. To deal with sand-production problems systematically, a sand-production control system (SCS) is first proposed in this paper, specialized for pore-distributed clayey silt hydrate reservoirs.

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 difficulties.

A Novel Analytical Approach To Estimate Sand Production

Summary Sand production is the migration of formation sand caused by the flow of reservoir fluids. This paper aims to develop an analytical model to predict sand production in oil field and validate it using 4 wells in Field “N”. Coupled sand failure mechanism considering static and dynamic criteria is used to models sand production. Rock particles strength is predominantly acting by drag ...

2021-8-3  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 assertive threshold which depends on factors like stress state, reservoir ...

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 ...
