Abstract: A fluid end for a high pressure pump with improved resistance to fatigue failure is disclosed. Interior surfaces that are prone to fatigue failure are laser peened to resist cracking and other types of failures. A work holder for supporting the fluid end as it is peened is also disclosed.

Abstract: Method for recovery of bitumen from tar sand is provided. An aqueous fluid containing a wetting agent and nanoparticles is injected into a first horizontal well at a temperature above reservoir temperature. Bitumen is released from sand grains and flows into a second horizontal well, where it is transported to surface. In a surface treatment facility, a slurry of tar sand is formed and surfactant and nanoparticles are added to the slurry.
Abstract: A valve assembly for use in high pressure pumps is designed for easy replacement for example in the suction inlet here for a high pressure pump. The design utilizes a combination of screw threads and a locking member to provide structural strength for the valve to be placed in and withdrawn from the inlet bore.
Abstract: A “slick water” fluid for hydraulic fracturing of wells is provided that is mixed by adding solid polymer and solid additives to water. The fluid may be batch mixed or mixed in a continuous process using standard blending equipment. Components are selected that are environmentally preferred. Lower cost and environmental benefits are realized.
