  • Patent number: 10385259
    Abstract: Treatment methods and treatment fluids for increasing permeability of organic shale formations are described herein. The treatment method includes treating an organic shale formation with a treatment fluid. The treatment fluid includes a solvent that dissolves bitumen in the shale formation. After treating the shale formation with the treatment fluid, oil is recovered from the shale formation. By removing bitumen from pores and pore throats within the formation, the solvent increases permeability of the formation and allows mobile oil to flow more easily through the formation.

  • Patent number: 9803130
    Abstract: A method of treating a subterranean formation, the method including placing a well treatment fluid comprised of at least an enzyme and a breaker additive in the subterranean formation. Initially, the pH of the well treatment fluid is about 11.5. The breaker additive reduces the pH of the well treatment fluid by at least 1.5 to increase the activity of enzyme and accelerate hydrolysis of a crosslinkable component.

  • Patent number: 9790419
    Abstract: A composition for treating a subterranean formation is formed from water, a water-soluble polymer and a crosslinking system. The crosslinking system utilizes 1) primary crosslinking agent of at least one of a dialdehyde benzene source, a dioxane, and a trioxane, 2) a secondary low temperature organic crosslinking agent that generates aldehyde, and 3) a phenol source. The crosslinking system provides the composition a delayed gel time of about 2 to about 20 hours at temperatures of about 250° F. (121° C.) or higher. A method of treating a subterranean formation penetrated by a wellbore is also accomplished by forming a treatment fluid from the composition and introducing the treatment fluid into the formation through the wellbore.

  • Publication number: 20150315456
    Abstract: Fluid compositions comprising water, an acid or an acid source, a chelating agent and a relative permeability modifier have utility in the context of matrix acidizing of oil bearing sandstone formations. Acidizing treatments with these compositions may improve the formation permeability to oil with respect to the permeability to water. The relative permeability modifier is a cationic polyacrylamide.

  • Publication number: 20150041134
    Abstract: A cement slurry composition is described as having cement, water, and organic polymer particles. The composition also includes non-ionic surfactants, which may contain ethoxylate groups or contain both ethoxylate groups and propoxylate groups in the hydrophilic part. The non-ionic surfactant acts to disperse the hydrophobic polymeric particles in the slurry, thereby reducing mixing time. The cement slurry composition is prepared and then pumped into the subterranean well and placed in a zone of the subterranean well. Time is then allowed for the cement slurry composition to set and form a solid mass in the zone.
