Abstract
A method including deploying a formation testing tool in a borehole, actuating first and second packers of the formation testing tool in the borehole, obtaining measurements in response to actuation of the first and second packers of the formation testing tool in the borehole, and analyzing the measurements to estimate at least a shear modulus (G) of a geological formation surrounding the borehole.
Claims20
A method, comprising:
- deploying a formation testing tool in a borehole;
- actuating first and second packers of the formation testing tool in the borehole;
- obtaining measurements in response to actuation of the first and second packers of the formation testing tool in the borehole;
- analyzing the measurements to estimate at least a shear modulus (G) of a geological formation surrounding the borehole;
- and
- controlling one or more parameters of at least one of the formation testing tool and wellsite equipment using the shear modulus (G), wherein analyzing the measurements to estimate at least the shear modulus (G) is performed in real-time upon obtaining the measurements, wherein the wellsite equipment comprises at least one of a drill string, a drill bit, or a bottom hole assembly (BHA), wherein the one or more parameters of the wellsite equipment comprise at least one of a composition of a drilling mud, a flow rate of the drilling mud, a rotational speed of a drill string, a rotational speed of a drill bit, a direction of drilling of the BHA, or a weight on the drill bit.
