  • Patent number: 11286726
    Abstract: Methods and systems are directed to the uniform distribution of a fluid through an annulus between a pipe and a wellbore wall, primarily when there is a preferential flow in one side of the annulus relative to another side of the annulus. Generally, the methods and systems involve introducing a first agent into the annulus, wherein the first agent is configured to cause swelling of a cladding on the exterior of the section of the pipe. The swelling reduces flow in the annulus on the side of the pipe with preferential flow so as to reduce the preferential flow on that side of the pipe.

    Abstract: A lost circulation material (LCM) having date fruit caps is provided. The date fruit cap LCM includes date fruit caps from a date tree. The date fruit caps have multiple flakes (for example, three flakes) attached at one end to an end cap and free at the other end. The date fruit caps may be obtained from the waste product of date tree and date fruit processing.

  • Patent number: 10513650
    Abstract: A fluid composition comprising: (A) a liquid hardenable resin component comprising a resin; and (B) a hardening agent component comprising a hardening agent for the resin; wherein at least one of the resin or the hardening agent comprises a molecule having at least one heavy atom. The substitution of one or more heavy atoms that have a higher atomic weight than the other atoms of the molecule, increases the molecular mass of the resin or hardening agent, and hence, the density of the fluid composition. A method of treating a treatment zone of a well, the method comprising: introducing the treatment fluid into a well bore; and allowing the treatment fluid to form a hardened mass the well bore.

  • Patent number: 10487253
    Abstract: A lost circulation material (LCM) having chips formed from date tree spikelets of a date tree is provided. The date tree spikelets may be obtained from the waste product of date tree and date fruit processing. The date tree spikelet-based LCM may be added to a drilling fluid (for example, a drilling mud) to mitigate or prevent such lost circulation in a well. The date tree spikelet-based LCM may be added to one or more additional LCMs as an LCM additive for addition to a drilling fluid (for example, a drilling mud) to mitigate or prevent such lost circulation in a well. Methods of lost circulation control with the date tree spikelet-based LCM are also provided.

  • Patent number: 10457848
    Abstract: A self-adaptive cement formulation includes cement, water and thermoplastic block-polymer particles. The set cement demonstrates self-healing properties when exposed to methane, and is particularly suited for well-cementing applications. After placement and curing, the self healing properties help maintain zonal isolation should bonding be disrupted between the set cement and the formation or a casing string, should cracks or defects appear in the set-cement matrix, or both.

  • Patent number: 10442980
    Abstract: Emulsions of mobility control polymers can be used to increase recovery of crude oil from a subterranean hydrocarbon-containing formation. A flooding fluid comprising the polymer emulsions are injected into a well that is in contact with the subterranean hydrocarbon-containing formation. The polymers can be temporarily cross-linked and have protected shear degradation and improved injectivity into the well; the shear resistance can be measured in terms of viscosity loss due to shear, and the improved injectivity can be measured in terms of the flooding fluid's filter ratio, flow rate, and viscosity.

  • Patent number: 10428261
    Abstract: In one embodiment, a method of formulating a sealant to span an opening and form a seal with surfaces across the opening is provided. The method further includes selecting a fluid material capable of contacting and adhering to the surface of the opening and which reacts to form a solid material as a result of a thermal reaction. The method further includes selecting and intermixing one or more solids with the fluid material to form a composite, wherein the solids migrate within a column of the composite sealant before the composite sealant cures from a fluid to a solid and bonds to the surfaces of the opening, and the change in volume of the lower portion of the composite sealant into which the solids have migrated, as the temperature thereof changes during curing, is insufficient to cause it to pull away from the surfaces of the opening or fail internally.
