Review of Sand Production Prediction Models - Hindawi

Nov 12, 2012 . These problems include, but are not limited to, plugging the perforations or production liner, wellbore instability, failure of sand control completions [1], .. rock behavior leads to excessive stress concentrations at the borehole wall and therefore results in overestimation of initial sand production conditions.

Practical Approaches to Sand Management - Schlumberger

Sand production is a serious problem in many oil and gas assets worldwide. It can . viscosities; once produced into the wellbore, . and if these exceed the strength of the rock in this geometry, the rock will fail and sand may be produced. Increasing depletion can change the in-situ stresses in the Earth, which can also.

A Geomechanical Wellbore Stability Assessment for Different .

Jul 24, 2014 . The major problems that geomechanics deals with are excessive mud loss, wellbore instability (hole enlargement, tight hole, stuck pipe, hole collapse, poor hole cleaning, poor logging, poor cementing), casing compression or shearing, reservoir compaction, surface subsidence, sand production, fault.

Predicting sand production - - PetroWiki

Jul 16, 2015 . This obviously will solve the sand production problem but will also increase costs and may reduce well productivity. . 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.

Mar 20, 2013 . Excessive water production is prevalent in mature fields globally where the ratio of water to oil produced increases to nine. This can have . Near-Wellbore Problems, Reservoir-Related Problems. Casing leaks . Production trends provide a good indication of the type of water-related problem. For example.

Sand Handling | Dover Artificial Lift

Excessive sand and solids in oil and gas wells pose serious problems for some artificial lift systems and for the well's overall production. Regardless of their source, . Our SPIRIT Downhole Sand & Solids Separator improves pump performance by removing solids before the fluid reaches the pump intake. The separator's.

Workovers - Lloydminster Heavy Oil

The chief problem here is to obtain a plastic which will consolidate the sand yet permit oil to flow through the result. Formation Damage. This common problem occurs when something happens to the formation near the wellbore, slowing oil production. For example, excessive buildup of water saturation in the vicinity of the.

ONS 2016: The synergy between sand control screens and inflow .

Aug 26, 2016 . The use of high deviation and horizontal trajectories in these wells has increased the amount of reservoir contacted by the wellbore, improving well productivity, and to some extent, reducing the potential for sand production by reducing the overall drawdown on the formation. To ensure the integrity of the.

Enhance Wellbore Stability - Halliburton

Low seabed temperatures and highly unconsolidated sands commonly found in deepwater West Africa compound wellbore stability problems as do high wellbore inclinations, long openhole sections and complex well trajectories. The possible presence of gas-hydrate deposits and tight pore-pressure fracture gradient.
