Verifying measurements of elastic anisotropy parameters in an anisotropic wellbore environment

A non-transitory computer-readable medium in which instructions are stored, the instructions being executable by a processing device for causing the processing device to:

• determine an estimate of an elastic anisotropy parameter for a first portion of an anisotropy formation through which a wellbore is formed, wherein the estimate of the elastic anisotropy parameter includes an estimate of a mud slowness parameter;
• receive a first signal comprising a first acoustic waveform received by a well tool positioned in the first portion;
• execute a first quality control analysis of the first signal by comparing first data derived from the first signal to a first reference value to determine a difference between the two;
• adjust the estimate of the elastic anisotropy parameter for the first portion based on the difference;
• receive a second signal comprising a second acoustic waveform received by the well tool positioned in a second portion of the anisotropy formation;
• execute a second quality control analysis of the second signal to determine a result, wherein the second quality control analysis is adapted to be performed by a different quality control analysis method than the first quality control analysis;
• adjust the estimate of the elastic anisotropy parameter for the first portion based on the result.

A system comprising:

• a well tool positionable in a first segment of a wellbore formed through a first portion of an anisotropic formation for receiving a first signal comprising an acoustic waveform received at the well tool and representing an elastic anisotropy parameter for the first portion, wherein the well tool is further positionable in a second segment of the wellbore formed through a second portion of the anisotropic formation for receiving a second signal representing elastic anisotropy parameters for the first portion and the second portion;
• a processing device communicatively coupleable to the well tool for:
• determining an estimate of the elastic anisotropy parameter for the first portion of the anisotropic formation, wherein the elastic anisotropy parameter includes a mud slowness parameter;
• executing a first quality control analysis of the first signal by comparing first data derived from the first signal to a first reference value to determine a difference between the two;
• adjusting the estimate of the elastic anisotropy parameter for the first portion based on the difference;
• executing a second quality control analysis of the second signal to determine a result, wherein the second quality control analysis is adapted to be performed by a different quality control analysis method than the first quality control analysis;
• adjusting the estimate of the elastic anisotropy parameter for the first portion based on the result.
