Abstract

Systems and methods for optimized geosteering include creating a parameter matrix, which comprises a formation property for each pair of true vertical depth (TVD) coordinates from a geological model and measured depth (MD) coordinates from a predefined well trajectory; updating the parameter matrix by replacing the TVD coordinates and the MD coordinates for each parameter entry in the parameter matrix with the TVD coordinates and the MD coordinates for an actual well trajectory; and compiling a distance to bed boundary (DTBB) array and one or more other logging while drilling (LWD) arrays using corresponding measurements at the MD coordinates of the actual well trajectory; and calculating a value for each parameter entry in the updated parameter matrix, which is a sum of a geology array, the DTBB array and the one or more other LWD arrays that are each multiplied by respectively assigned or calculated weights.
