Description

Automatic adjacent well selection method for downhole tool performance evaluation Cross Reference to Related Applications The present application claims priority from U.S. provisional patent application No. 63/590,018, filed on 10/13 at 2023, incorporated herein by reference. Background The performance of drill bit operations relative to "adjacent well" operations has been evaluated for a long time. The evaluation is performed in a "field job report" (FRR) in which drill/field/production engineers evaluate the relationship of the test job to their selected adjacent well jobs. These adjacent well operations are selected based on a number of criteria, such as geographic location, depth and formation of drilling, BHA design, customer (carrier, contractor, rig), and drilling parameters, in an attempt to find the most similar bit operation to compare to make the bit performance assessment as fair as possible. However, this process is performed manually and the final neighbor well selected is therefore subjective. People are trained in various ways to select adjacent well operations, and the selection rules vary based on who trained the person or the geographical area in which the person is trained. Such performance evaluation methods may be applied to any drilling system component, such as rotary steerable tools, downhole motors, drilling fluids, and the like. Disclosure of Invention A method for selecting one or more adjacent well operations for performance evaluation at a wellsite is disclosed. The method includes determining that the drilling operation is a valid target operation. The method also includes identifying potential neighboring well operations based on the target operation. The method also includes determining a score for each of the potential adjacent well operations. Determining the score includes determining a parameter score for a plurality of parameters. The parameter scores are weighted such that some of the parameters have higher potential values than others of the parameters. Determining the score further includes determining a total score based on the parameter score. The parameters include a radial geographic distance between the target job and the potential adjacent well job, an absolute difference between a run-in depth of the target job and the potential adjacent well job, a difference between a job date of the target job and the potential adjacent well job, an operator name of the target job that matches the potential adjacent well job, a type of drilling rig of the target job that matches the potential adjacent well job, a drilling contractor of the target job that matches the potential adjacent well job, a type of downhole drive of the target job that matches the potential adjacent well job, a job direction of the target job that matches the potential adjacent well job, a mud type of the target job that matches the potential adjacent well job, and a well target zone formation of the target job that matches the potential adjacent well job. The method also includes ranking the potential adjacent well operations based on the score of each of the potential adjacent well operations. The method also includes identifying a subset of potential adjacent well operations based on the ranking. The potential adjacent well operations in the subset are most similar to the target drilling operation. The method also includes comparing the drilling performance of the target job to statistics (e.g., median) of drilling performance of a subset of potential adjacent well operations. The comparison of drilling performance includes a first graph showing drilling distance versus average rate of penetration (ROP). The method also includes determining an improvement score based on the comparison of drilling performance. The improvement score is positive in response to the target job performing better than the statistics of drilling performance. The improvement score is negative in response to the target job performing worse than the statistics of drilling performance. The method also includes comparing the plurality of drill bit job groups to one another based at least in part on the improvement score. The comparison of the sets includes a second graph showing the median drilling distance and ROP improvement score for each of the drill bit working sets. The method also includes selecting one of the drill bit work groups based on the comparison of the groups. The method also includes performing a wellsite action based on the selected group. Performing the wellsite actions includes drilling the wellbore using drilling system components from the selected set. A method for selecting potential adjacent well drilling operations to automatically evaluate the drilling performance of a target drilling operation is also disclosed. The method includes identifying potential adjacent well drilling operations based on the target drilling operation. Potential adjacent well drilling operations are identified based on the st
