Abstract: Non-spherical particulates are useful in the stimulation of subterranean formations. A proppant pack composed of the non-spherical particulates exhibits greater porosity than a corresponding proppant pack composed of spherical particulates. In addition, the non-spherical particulates exhibit higher conductivity at higher stresses than spherical shaped particulates.

Abstract: Embodiments of the invention include a proppant testing apparatus with a portable piston extractor and related methods. In one embodiment, a testing apparatus includes a test cell body in which an upper piston is constrained to vertically reciprocate within a test cavity. A laterally-extending width bar is coupled to the piston above the test cell body. A portable piston extractor is provided for freeing the stuck piston following testing. The piston extractor includes an extractor base removably supported on the test cell body and an extractor arm movably coupled to the extractor base. A drive mechanism is configured for driving the extractor arm into vertical engagement with the width bar, to raise the piston for extraction. In another embodiment, a set of gear boxes interconnected by shafts may be used to apply a uniform separation force between the piston and test cell body.

Abstract: Non-spherical particulates are useful in the stimulation of subterranean formations. A proppant pack composed of the non-spherical particulates exhibits greater porosity than a corresponding proppant pack composed of spherical particulates. Non-spherical particulates which are hollow and non-porous may further be at least partially filled with a chemical treatment agent including water-soluble or oil-soluble chemical treatment agents.

Abstract: Methods and compositions useful for subterranean formation treatments, such as hydraulic fracturing treatments and sand control that include porous materials. Such porous materials may be selectively configured porous material particles manufactured and/or treated with selected glazing materials, coating materials and/or penetrating materials to have desired strength and/or apparent density to fit particular downhole conditions for well treating such as hydraulic fracturing treatments and sand control treatments. Porous materials may also be employed in selected combinations to optimize fracture or sand control performance, and/or may be employed as relatively lightweight materials in liquid carbon dioxide-based well treatment systems.

Abstract: Embodiments include an apparatus and method for testing a particulate material suitable for use as a proppant. According to one embodiment, a sample of the particulate material is captured in the cavity of a test vessel between a cavity wall and a piston sealed with the cavity wall. A fluid is flowed into the test vessel from a fluid inlet of the test vessel to wet the sample of particulate material. The fluid is pressurized to a target fluid pressure greater than ambient pressure and heated to a target temperature greater than ambient temperature. The piston is moved into direct contact with the particulate material with sufficient force to crush at least a portion of the particulate material while maintaining one or both of the target temperature and the target pressure for one or more test cycles. Each test cycle has a duration of at least about 120 seconds and as long as about 24 hours.

Abstract: Methods and compositions useful for sand control and/or hydraulic fracturing of subterranean formations that utilize relatively lightweight and/or substantially neutrally buoyant particles as particulate sand control or proppant material. Particles that may be employed include particulates of naturally-occurring materials that may be optionally strengthened or hardened by exposure to a modifying agent. Effectiveness of a modifying agent may be optionally enhanced by facilitating interaction between a modifying agent and one or more components present in a naturally occurring material by using enhancing agents and/or by using conditions that enhance interaction.
