Abstract: Methods, computing systems, and machine-readable media for detecting downhole sand entry points are provided. A computing device receives a sand detection output of a product sand detection tool and a raw timeseries waveform corresponding to an input to the product sand detection tool. Based on the sand detection output, at least one downhole sand entry point is detected at a logging depth. In response to the detecting of the at least one downhole sand entry point. the computing device extracts a subset of features based on the raw timeseries waveform. The computing device determines whether the detecting is a true positive or a false positive based on the extracted subset of the features and a trained Random Forest classifier. A remedial action is performed regarding the at least one downhole sand entry point responsive to the determining that the detecting is the true positive.

Abstract: A use, as an emulsifying base in a cosmetic or pharmaceutical formulation, of a composition comprising a mixture of alkali metal stearoyl glutamate and stearoyl glutamic acid, characterised in that the surfactant has a pH of between 7.8 and 9.2, measured at 25° C. in a 5% by mass aqueous solution, and in that the composition comprises between 0.2 g and 0.5 g of aqueous phase/g of surfactant. Method of manufacturing the emulsifying base and cosmetic or pharmaceutical composition containing it.

Abstract: The present invention relates to a water-in-oil surfactant consisting of a mixture of compounds of formula (I): wherein the compound of formula (I) has an average degree of polymerisation n of between 4 and 6, R1, R2 and R3 being, independently of one another, a hydrogen atom or a group R4 derived from at least one carboxylic acid, the carboxylic acid being 12-hydroxystearic acid or a mixture of 12-hydroxystearic acid and ricinoleic acid. The present invention also relates to a surfactant composition and to a cosmetic composition comprising this surfactant.
