  • Patent number: 9617459
    Abstract: This invention relates to water-based well drilling fluids. It has been found that cellulose based particles, which comprise cell wall material and their networks of cellulose based fibers and nanofibrils can be used to produce suspensions having viscosity and rheological properties particularly suitable for use as a drilling fluid. It is assumed that the organization of the cellulose fibrils, as it exists in the parenchymal cell walls, is at least partly retained in the cellulose based particles of the invention, even though part of the pectin and hemicellulose is removed there from. Breaking plant-based pulp down into this kind of cellulose based particles involves fewer and gentler processes than to break the pulp down further into cellulose nanofibrils, and therefore the present cellulose based particles can be produced much faster and at lower cost than completely unraveled cellulose nanofibrils.

Such materials degrade in 60 C water in less than 30 days, <14 days, and even <7 days. Various materials are provided that can degrade equally fast at lower temperatures, such as 50 C, or even 40 C.

  • Patent number: 9617463
    Abstract: A fracturing fluid, gravel pack fluid and/or frac pack fluid containing particles such as proppants, gravel and/.or sand, may contain an effective amount of a nano-sized particulate additive to fixate or reduce fines migration, where the particulate additive is an alkaline earth metal oxide, alkaline earth metal hydroxide, alkali metal oxides, alkali metal hydroxides transition metal oxides, transition metal hydroxides, post-transition metal oxides, post-transition metal hydroxides piezoelectric crystals and pyroelectric crystals. The nano-sized particulate additive is optionally bound to the particles with a coating agent such as an oil, alcohol, glycol, glycol ethers, ketones, terpenes, etc. The particle size of the magnesium oxide or other agent may be nanometer scale but may be a larger scale than nanometer but still relatively small, which scale may provide unique particle charges that help fixate the formation fines.

  • Patent number: 9617464
    Abstract: In an embodiment of the disclosure, mixtures of different carbon length alcohols are used as the primary feedstock for Guerbet alcohols. Specifically, embodiments relate to a method of synthesizing mixed molecular weight additives from a mixture of primary alcohols comprising, receiving a mixture of primary alcohols having greater than two different chain length primary alcohols and reacting the mixture of primary alcohols in a single reactor to produce a mixture of at least five Guerbet alcohols. The mixture of Guerbet alcohols can then be used to produce an additive or surfactant composition comprising additives or surfactants of different molecular weights.

  • Patent number: 9617465
    Abstract: A method of treating a subterranean formation includes combining self-degrading particles with a carrier fluid, placing the self-degrading particles and the carrier fluid into a zone in a formation, said zone comprising fractures, allowing the self-degrading materials to penetrate and plug off the connection to existing fractures and to bridge off fracture propagation near the wellbore, and initiating a re-fracture treatment comprising re-fracture fluids and proppant materials prior to the degradation of the self-degrading particles.

  • Patent number: 9617466
    Abstract: A microencapsulation process is improved by adding a stabilizing agent that contains one or more catalytic organo-metal oxide materials, such as metal soaps. This functions as a crosslinker by causing unsaturated bonds in the microcapsule walls to react, thereby stabilizing the microcapsules against the effects of additives to coatings that, otherwise, degrade the functionality of thermochromic or photochromic materials at the microcapsule core.
