Abstract
A method includes mixing, in an active pit, a drilling fluid to be introduced to a wellbore; receiving, through a flowline, the drilling fluid from the wellbore; obtaining sensor data, using one or more sensor coupled to at least one of the active pit and the flowline, on at least one of coefficient of friction and lubricant content of the drilling fluid; and determining, using an automated control system, whether a lubricant needs to be added to the drilling fluid based on the sensor data.
Claims12
A method, comprising:
- mixing, in an active pit, a drilling fluid to be introduced to a wellbore;
- receiving, through a flowline, the drilling fluid from the wellbore;
- obtaining sensor data, using sensors disposed in the active pit and in the flowline, on coefficient of friction and lubricant content of the drilling fluid before and after being introduced to the wellbore;
- and
- comparing a first piece of the sensor data obtained at the active pit, a second piece of the sensor data obtained at the flowline, and predetermined values of coefficient of friction and lubricant content, for evaluating a loss of the drilling fluid and for determining whether a lubricant needs to be added to the drilling fluid.

A system, comprising:
- an active pit containing a drilling fluid to be introduced to a wellbore;
- a flowline receiving the drilling fluid from the wellbore, sensors disposed in the active pit and in the flowline and configured to obtain sensor data on at least one of coefficient of friction and lubricant content of the drilling fluid before and after being introduced to the wellbore;
- and
- an automated control system configured to make a determination on whether a lubricant needs to be added to the drilling fluid and configured to evaluate a loss of the drilling fluid, by comparing a first piece of the sensor data obtained at the active pit, a second piece of the sensor data obtained at the flowline, and predetermined values of coefficient of friction and lubricant content.
