Patent number: 10209401Abstract: According to the invention, a training image denotes, for each cell of a first three-dimensional grid, a respective type of geological facies assigned to said cell. For each cell of a second three-dimensional grid, the morphology of which is matched to estimated geological horizons, the well data comprise a respective type of geological facies estimated for said cell. Two-dimensional patterns, each of which is defined along a respective geological horizon and includes, in a cell containing the intersection of a well with said geological horizon, the type of geological facies estimated for each cell, are defined. The instances of the identified two-dimensional patterns are counted in the training image so as to verify the ability of the training image to account for correlations between wells.Type: GrantFiled: July 24, 2012Date of Patent: February 19, 2019Assignee: TOTAL SAInventors: Cyril Ronot, Philippe Ruelland, Pierre Biver

Patent number: 9766357Abstract: Method for optimal stacking of seismic images to remove noise and enhance signals in seismic images (101) outputted from a Reverse Time Migration (RTM) imaging process. Dip information is calculated (102) and then sorted by image point (104), for each seismic image to be stacked. A dominant dip and azimuth is determined at each image point (106), and only those events are stacked (107). If the image is still noisy or lacking in detail (108), the process may be iterated (109) to improve the selection of most likely dip and azimuth.Type: GrantFiled: September 19, 2014Date of Patent: September 19, 2017Assignee: ExxonMobil Upstream Research CompanyInventors: Young Ho Cha, William Curry
