摘要： A method for determining a property of a geological formation based on an optical image of rock samples taken from the formation is presented therein. The image comprises a plurality of pixels and the method comprises defining windows in the image, each window comprising predetermined number of pixels and being of a predetermined shape. The method also includes, for each window, extracting a rockprint value representative of the window. A rockprint comprises indicators for characterizing a texture of the window. The method also includes classifying the windows into categories of a predetermined set. Each category is representative of one type of rock and the classification is based on a comparison of the rockprint value of each window with rockprint values of images of reference rock samples for each category. Based on the classification, the method then includes determining the at least one property of the geological formation, ie the quantification of each type of rock in the sample.

摘要： A method for detecting a malfunction during a drilling operation is carried out by making use of a drill bit, the method including the following: a) the comparison of a first magnitude (E) representative of the mechanical specific energy (MSE), with a first threshold value (Emax); b) when the first magnitude is greater than the first threshold value, the comparison of the ratio (E/S) between the first magnitude and a second magnitude (S) representative of the drilling force with a second threshold value ((E/S)max); c) the detection of a malfunction in the drilling operation when the ratio (E/S) between the first magnitude (E) and the second magnitude (S) is greater than the second threshold value ((E/S)max). The method provides the ability to ensure more precise detection of a malfunction during drilling operations.

摘要： Tension meter (82) for measuring a mechanical tension (F1) along a longitudinal direction (L) between a first element (84) and a second element (80) deployed in a well containing a fluid (50) having a fluid pressure, the tension meter comprising:—a bar (108) comprising a first portion (152), a second portion (154), and a measurement portion (156), and—a hollow member (110) defining a first chamber (169) surrounding the measurement portion, the bar being free to expand within the hollow member under the mechanical tension (F1) to be measured. The measurement portion includes at least one strain gauge (172). The tension meter includes first sealing elements for keeping the first chamber at a first chamber pressure, the measurement portion being subject to a compression force (F2) due to a difference between the fluid pressure and the first chamber pressure. The tension meter includes means for converting the fluid pressure into a traction force (F3) applied on the second portion (154), wherein the compression force (F2) and the traction force (F3) compensate. Related subassembly and method.

摘要： Method and apparatus for determining the relative content of a first rock species and of a second rock species in a rock sample extracted from a wellbore. The method comprises adding a reactant to the rock sample, measuring a first information (PT1) relative to a first amount of compound produced at a first instant (T1) and a second information (PT2) relative to a second amount of compound produced at a second instant (T2). The method also comprises calculating the relative content of the first species in the rock sample from the first information (PT1) and calculating the relative content of the second species in the rock sample from the second information PT2). The method comprises determining a corrected amount (Cv) of compound generated by the reaction of the second species with the reactant at the first instant (T1), and calculating the relative content of the first species in the rock sample and the relative content of the second species in the rock sample based on the corrected amount (Cv).
