CPC E21B 47/006 (2020.05) [E21B 37/00 (2013.01); E21B 2200/20 (2020.05)] | 18 Claims |
1. A method, comprising:
obtaining, by a computer processor, caliper log data regarding a first well comprising a plurality of tubulars, wherein the caliper log data corresponds to a portion of a caliper log that is acquired using a caliper logging tool in the first well with the plurality of tubulars;
determining, by the computer processor and using a first descaling model and the caliper log data, a plurality of predicted caliper log values for a descaled well,
wherein the descaled well corresponds to the first well following a first scale treatment,
wherein the first descaling model is a linear regression model that is determined using a plurality of caliper logs based on a plurality of wells, and
wherein the plurality of predicted caliper log values correspond to a prediction of a diameter of one or more joints in the first well following the first scale treatment;
determining, by the computer processor, whether the descaled well satisfies a predetermined criterion based on the plurality of predicted caliper log values,
wherein the predetermined criterion is selected from a group consisting of a pressure threshold of a tubular, a physical dimension of a thickness of the tubular, a maximum allowable operating pressure of the tubular, and a predetermined change in well productivity for the first well;
determining, by the computer processor and in response to determining that the descaled well fails to satisfy the predetermined criterion, a tubular replacement for the first well; and
transmitting, by the computer processor and to a control system, a command that implements the tubular replacement,
wherein the tubular replacement corresponds to a change of at least one tubular among the plurality of tubulars to a different tubular in the first well.
