Embodiment

[0087] A test setup consisting of the following components was used: a flowback tank for containing the tested proppant pack; a circulation system in the tank for pumping fluid through the proppant pack; a hydraulic press to apply uniaxial closure stress to the proppant filling body. The flowback cell consisted of a cuboid with an internal 5.25 inch by 5.25 inch (13.3 cm by 13.3 cm) working area that accommodated the proppant pack. When the unit is filled with a proppant pack, a square piston is inserted into the cuboid on top of the proppant pack. Water is pumped through the rectangular proppant pack, passing from the upstream inlet side to the outlet side. On the upstream side of the unit, there are three 13 mm inlets for water inflow. On the outlet side of the unit, there is a 10mm outlet, shown as a small hole. In this structure, the proppant pack can move if it is not strong enough to withstand the stresses caused by the water flow. After the flowback unit is filled a...

Abstract

Methods of contacting a subterranean formation are described which provide improved control or reduction of particulate migration, transport or flowback in wellbores and reservoirs, and which may do so without sacrificing substantial hydraulic conductivity. One method comprises injecting into a well-bore intersecting the subterranean formation a fluid composition comprising a first component and a second component dispersed in a carrier fluid, at least a portion of the first component or second component being provided as at least one multicomponent article having an aspect ratio greater than 1:1.1; forming a network comprising the first component; and binding the network with the second component.

Description

Background technique [0001] The present disclosure relates to recovering hydrocarbons from a formation. In particular, the present disclosure relates to methods of recovering hydrocarbons from a formation using fluid compositions. [0002] During the production of petroleum or other fluids from a formation, the undesired transfer or flowback of formation or particulate solids is a problem in production operations. For example, migrating particulate solids in the formation can restrict flow in the wellbore, restricting or completely preventing fluid production. Additionally, the displaced solids can greatly increase fluid friction, thereby increasing pumping requirements, and can cause severe wear and tear on production equipment, especially pumps and seals used in the production process. Finally, the undesired particulate solids in the recovered product fluid must be separated in order to make the product fluid commercially usable. [0003] In some instances, unwanted parti...
