METHOD AND SYSTEM FOR PERFORMING FRICTION FACTOR CALIBRATION

摘要

Calibrating Friction Factors. At least some of the illustrative embodiments are methods including: calibrating friction factor for a drilling operation by: plotting on a display device the expected hook load versus depth for the drilling operation; displaying plot points on the display device, each plot point indicative of a measured hook load versus depth for the drilling operation; selecting a plot point associated with a depth, the selecting responsive to a cursor hovering over the plot point on the display device; displaying a friction factor values which correlates the expected hook load versus depth for the particular depth to the measured hook load versus depth for the plot point, selecting the value responsive to the cursor hovering over the value; and then shifting on the display device at least a portion of the indication of expected hook load versus depth based on the value of friction factor.

1. A method comprising:
calibrating friction factor for a drilling operation, the calibrating by:
plotting on a display device an indication of expected hook load versus depth for the drilling operation;displaying a plurality of plot points on the display device, each plot point indicative of a measured hook load versus depth for the drilling operation;selecting a first plot point of the plurality of plot points, the first plot point associated with a first depth, and the selecting responsive to a pointer cursor residing within a predetermined distance of the first plot point on the display device;displaying a first value of friction factor which correlates the expected hook load versus depth for the particular depth to the measured hook load versus depth for the first plot point, the displaying the value responsive to the selecting the first plot point;selecting the first value responsive to the pointing cursor residing within a predetermined distance of the first value; and thenshifting on the display device at least a portion of the indication of expected hook load versus depth based on the first value of friction factor.
