The present invention provides methods of stimulating fluid production from an unconsolidated formation penetrated by a wellbore while preventing the migration of formation sand with fluids produced from the formation. The methods basically comprise the steps of injecting a liquid composition into a portion of the formation surrounding the wellbore which converts into a gel-like substance and plugs the permeability of the injected portion of the formation, but allows the injected portion to remain flexible and resist breakdown due to pressure cycling therein, creating at least one fracture in the formation extending from the wellbore through the plugged portion of the formation into an unplugged portion thereof and depositing hardenable resin composition coated proppant in the fracture and causing the resin composition to harden and consolidate the proppant into a hard permeable mass.

Stimulating fluid production from unconsolidated formations

A core sample test apparatus applies pressure to the core sample and measures responsive longitudinal deformation with two sensors and lateral deformation with two orthogonal pairs of diametrically disposed sensors. The apparatus holds the core sample under test in a sleeve to which no or insignificant end torsional forces are applied during installation due to rotationally blocked washers used adjacent the ends of the sleeve. Concurrent acoustic testing can also be applied.

Core sample test method and apparatus

A method and system for testing a two-phase compressible composition, such as a foamed cementing composition, enables testing for mechanical properties while maintaining original pressurized gas volumes in the composition. A specimen of the composition can be prepared, transferred and tested without disrupting the dynamic status of the specimen. This allows for testing of the composition under conditions in which the composition will be placed in an oil or gas well. A related specimen test device is also disclosed. The method includes pressurizing the two-phase compressible composition in a first vessel to a pressure greater than atmospheric pressure; pressurizing a second vessel to the pressure; transferring at least a portion of the composition from the first vessel to the second vessel while maintaining at least substantially the pressure on the transferred portion of the composition; and testing the portion of the composition transferred to the second vessel, which testing is performed while maintaining at least substantially the pressure in the second vessel.

The present invention provides methods of stimulating fluid production from an unconsolidated formation penetrated by a wellbore while preventing the migration of formation sands with fluids produced from the formation. The methods basically comprise the steps of injecting a hardenable resin composition into a portion of the formation surrounding the wellbore whereby that portion is consolidated into a hard permeable mass, forming an indentation in the wellbore to facilitate the initiation of a fracture in the consolidated portion of the formation, creating a fracture in the formation extending from the wellbore through the consolidated portion of the formation into an unconsolidated portion thereof and depositing hardenable resin composition coated proppant in the fracture whereby the proppant is consolidated into a hard permeable mass.

Stimulating wells in unconsolidated formations

Methods of completing poorly consolidated subterranean formations bounded by one or more consolidated formations to prevent sand production from the poorly consolidated formations are provided. The methods basically comprise the steps of drilling a well bore into the consolidated boundary formation adjacent to the poorly consolidated formation, creating a propped fracture communicating with the well bore in the consolidated boundary formation which extends into the poorly consolidated formation and producing fluids from the poorly consolidated formation into the well bore by way of the propped fracture.
