Abstract
Official abstract text for this publication.
Methods for drilling a wellbore within a subsurface region and drilling assemblies and systems that include and/or utilize the methods are disclosed herein. The methods include receiving a plurality of drilling performance indicator maps, normalizing the plurality of drilling performance indicator maps to generate a plurality of normalized maps, adaptive trending of the plurality of drilling performance indicator maps to generate a plurality of trended maps, summing the plurality of trended maps to generate an objective map, selecting a desired operating regime from the objective map, and adjusting at least one drilling operational parameter of a drilling rig based, at least in part, on the desired operating regime.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method of drilling a wellbore, with a drill string of a drilling rig, within a subsurface region, the method comprising: engaging a drilling control system in communication with the drilling rig, the drilling control system including a controller comprising a memory and a processor, the controller configured for; (i) receiving a plurality of drilling performance indicator maps, wherein each of the plurality of drilling performance indicator maps includes information regarding a corresponding mathematically derived drilling performance indicator of a drilling operation of the drilling rig, and further wherein each of the plurality of drilling performance indicator maps describes the corresponding mathematically derived drilling performance indicator as a function of a plurality of independent drilling operational parameters of the drilling rig; (ii) normalizing the plurality of drilling performance indicator maps with corresponding non-constant normalizing functions to generate a plurality of normalized maps, wherein the plurality of normalized maps is defined within a coextensive normalized map range; (iii) adaptively trending the plurality of normalized maps with corresponding trending parameters to generate a plurality of trended maps, wherein the adaptively trending of a given normalized map of the plurality of normalized maps is based, at least in part, upon at least one statistical parameter derived from the corresponding mathematically derived drilling performance indicator; (iv) summing the plurality of trended maps to generate an objective map that describes a correlation between a combination of the plurality of trended maps and the plurality of independent drilling operational parameters; (v) selecting, from the objective map, a desired operating regime for the drilling operation; and (vi) adjusting, based at least in part on the selecting, at least one drilling operational parameter of the plurality of independent drilling operational parameters to generate a plurality of adjusted independent drilling operational parameters; using the generated plurality of adjusted independent drilling operational parameters in the drilling control system to select an adjusted independent drilling operational parameter for operating the drill string with the drilling rig; sending a signal from the drilling control system indicative of the selected adjusted independent drilling operational parameter to an operating controller for the drilling rig; and drilling with the drill string at least a portion of the wellbore within the subsurface region using the operating controller for the drilling rig with the selected adjusted independent drilling operational parameter. 2. The method of claim 1 , wherein the normalizing includes nonlinearly normalizing at least one of the plurality of drilling performance indicator maps. 3. The method of claim 1 , wherein the plurality of drilling performance indicator maps includes a rate of penetration map, and further the normalizing includes linearly normalizing the rate of penetration map between 0 and 1 according to the equation ROP _ = ROP - ROP min ROP max - ROP min , where ROP is a normalized rate of penetration map, ROP is an individual rate of penetration data point from the rate of penetration map, ROP min is a minimum value of the rate of penetration map, and ROP max is a maximum value of the rate of penetration map. 4. The method of claim 1 , wherein the plurality of drilling performance indicator maps includes a depth of cut map, and further wherein the normalizing includes linearly normalizing the depth of cut map between 0 and 1 according to the equation DOC _ = DOC - DOC min DOC max - DOC min , where DOC is a normalized depth of cut map, DOC is an individual depth of cut data point from the depth of cut map, DOC min is a minimum value of the depth of cut map, and DOC max is a maximum value of the depth of cut map. 5. The method of claim 1 , wherein the plurality of drilling performance indicator maps includes a ratio of depth of cut to weight on bit map, and further wherein the normalizing includes linearly normalizing the ratio of depth of cut to weight on bit map between 0 and 1 according to the equation DOC _ WOB _ = DOC WOB - DOC min DOC WOB max - DOC WOB min ,
