  • Patent number: 12173225
    Abstract: An drilling mud composition is described, which includes an aqueous base fluid, a viscosifier, and a weighting material The drilling mud composition also includes an anti-sagging agent that comprises a dimethylamino methyl ester, such as methyl 5-(dimethylamino)-2-methyl-5-oxopentanoate. The anti-sagging agent may be used to prevent barite sagging, where barite is used as a weighting material. Small amounts of the anti-sagging agent may be used to maintain a low sag factor while drilling, and without causing unwanted increases in viscosity. The anti-sagging agent is effective for both vertical and inclined wellbores.

  • Patent number: 12157854
    Abstract: A drilling fluid composition includes an aqueous base fluid, 0.01 to 10 wt. % of a date palm leaves extract (DPLE), 1 to 10 wt. % of clay particles, and 0.01 to 1 wt. % of a base, where each wt. % based on a total weight of the drilling fluid composition. The DPLE is homogenously disposed on surfaces of the clay particles. The clay particles disposed with the DPLE are present in the drilling fluid composition in the form of a composite. A pellet made from the clay particles treated with the DPLE has a swelling value at least 75% less than a swelling value of the pellet in an aqueous composition that does not contain the DLPE.

  • Patent number: 12141124
    Abstract: A database system enumerates one-column candidate referential integrities (1CRIs) from a plurality of input columns in one or more relations. The database system applies one or more disqualification tests to the 1CRIs to eliminate illegitimate 1CRIs resulting in a list of non-disqualified 1CRIs, wherein the disqualification tests are applied to an 1CRI being tested (hereinafter (A*,B*), A* representing a set of values of a referenced column or columns and B* representing a set of values of a referencing column or columns) until (A*,B*) is disqualified or until all of the disqualification tests have been executed and (A*,B*) has not been disqualified, in which case (A*,B*) is added to the list of non-disqualified 1CRIs, wherein each of the disqualification tests reduces the likelihood of incorrectly adding (A*,B*) to the list of non-disqualified 1CRIs.

  • Publication number: 20240192155
    Abstract: A method to measure acid diversion efficiency in rock samples. The method includes measuring a first porosity and a permeability of the rock samples. The method includes flooding a core region of the rock sample with a hydrochloric acid (HCl) system to create a wormhole, wherein during the flooding the HCl system penetrates from a first end of the rock sample to a second end of the rock sample to form the wormhole. The method includes measuring a second porosity, a pore size distribution, and a diffusion tortuosity of the rock samples with NMR. The method includes establishing a diversion index (DI) based off a ratio between the diffusion tortuosity in a first direction and the diffusion tortuosity in a second direction. The method includes determining the acid diversion efficiency based off the diversion index.
