Publication number: 20240144647Abstract: A method for evaluating solid drilling fluid additives such as lost cuttings materials (LCM) includes acquiring a calibrated digital image of solid particles separated from drilling fluid circulating in a wellbore. The calibrated digital image is processed to identify individual ones of the solid particles depicted in the image. Color features and/or texture features are extracted from the identified solid particles depicted in the image. The extracted color and/or texture features are processed to identify LCM particles among the identified solid particles and to classify each of the identified LCM particles into one of a plurality of LCM classes and thereby obtain an LCM particle classification.Type: ApplicationFiled: October 28, 2022Publication date: May 2, 2024Inventors: Reda Karoum, Steven Young, Karim Bondabou, Maneesh Pisharat, Tetsushi Yamada

Patent number: 10781692Abstract: 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.Type: GrantFiled: May 7, 2018Date of Patent: September 22, 2020Assignee: SCHLUMBERGER TECHNOLOGY CORPORATIONInventors: Matthias Francois, Josselin Kherroubi, Alexis He, Tetsushi Yamada, Quentin Corlay, Karim Bondabou

Patent number: 10755427Abstract: The disclosure relates to methods and systems for analyzing an image of the formation intersected by a borehole. One of the methods determines a local apparent dip of the borehole at least at a measured depth i represented on the image, applies at least a window to the image, wherein each of the windows includes one of the measured depth i and is shaped as a function of the determined local dip at the corresponding measured depth i, compares a texture of at least a first zone of each window and a texture of at least a second zone of said window, wherein each of the first and second zones are adjacent and shaped as a function of the determined dip. Based on the comparison, the method determines at least a location of a texture boundary and derives a property of the formation. The other method includes determine locations of the texture boundaries, segmenting the image as a function of the texture boundaries, and perform clustering of the segments in order to determine a facies of the formation.Type: GrantFiled: May 23, 2018Date of Patent: August 25, 2020Assignee: SCHLUMBERGER TECHNOLOGY CORPORATIONInventors: Yuki Matsumura, Tetsushi Yamada, Josselin Kherroubi, Isabelle Le Nir
