  • Publication number: 20250046445
    Abstract: A syringe pump includes a lead screw, a motor, and a sliding block assembly. The lead screw has threads and the motor is coupled to the lead screw to rotate it. The half-nut housing has a half nut and a barrel cam. The half nut is disposed within the half-nut housing. The half nut has half-nut threads at an end adjacent to the lead screw void. The half nut engages or disengages with the threads of the lead screw. The half nut includes a half-nut cam-follower surface and a half nut slot. The barrel cam is disposed within the half-nut housing and engages with the half-nut cam-follower surface. The barrel cam includes a pin to fit within the half nut slot such that the barrel cam rotates between a first position and a second position to actuate the half nut between the engagement position and the disengagement position, respectively.

  • Publication number: 20100300693
    Abstract: The present application describes improved total recovery of oil, condensate and associated gas in a subterranean formation such that said hydrocarbons are released by a hydraulic fracturing process with a non-gel hydraulic fracturing fluid that comprises an enzyme surfactant fluid with at least one anionic surfactant thereby forming a non-gel hydraulic fracturing fluid enzyme surfactant composition which is injected at 1 to 3 percent of total frac fluid during fracturing.

  • Publication number: 20090266547
    Abstract: Disclosed is a system for injecting an enzymatic fluid composition into a gas or gas and oil near-well bore having a wide temperature range. The enzymatic fluid composition is a treatment for reducing oil deposits, asphaltenes, waxes, scale, or other hydrocarbon materials in a gas well or a combination gas/oil well where the production of gas is greater than 50% on a barrel of oil equivalent (BOE) basis.
