  • Patent number: 11155748
    Abstract: An effective amount of amphiphilic star polymers and surfactants may be applied to downhole fluids containing oil-in-water and water-in-oil emulsions, such as drilling fluids, completion fluids, drill-in fluids, workover fluids, and remediation fluids, to stabilize the emulsions and improve rheological properties of these fluids for use in oil and gas production operations. The star polymers and surfactants may be applied to the downhole fluid separately or as a blend to generate emulsions within the fluid that have substantially uniform droplet size.
    Type: Grant
    Filed: October 14, 2019
    Date of Patent: October 26, 2021
    Assignee: BAKER HUGHES OILFIELD OPERATIONS LLC
    Inventors: Wen Shao Cao, Grant Mackenzie, Dennis Clapper

  • Publication number: 20200158619
    Abstract: In a fracture pressure transmission test apparatus utilizing fracture simulating slotted discs, the apparatus can assess the effectiveness of a lost circulation material (LCM) in a test fluid, allow for the assessment of the ability of the LCM to reduce pressure transmission to a tip of a fracture to prevent fracture propagation, and allow for the simulation of flow back to assess the ease of clean-up for reservoir applications.

  • Publication number: 20190265150
    Abstract: A permeability plugging apparatus disk including a body, and a slot through the body, the slot being non-straight. Also disclosed is method for producing a particulate plugging apparatus disk including estimating a feature to be replicated for particle plugging testing, depositing layer by layer of a material according to a program in an additive manufacturing tool, leaving selective voids in the layer by layer construction to form the disk having a non-straight slot in a body and a permeability plugging apparatus disk including a body defining a pulser screen.
