2024 11 02 Profiles of Courage - Devan Grubb (Mudlogger)

Nov 2, 2024

This morning, Saturday, November 1, 2024, 6:00 am MST, we are POOH to change out the bit & BHA and make some rig upgrades that improve P rates. The TD of the hole is still at 10,785’.

Yesterday was quite an eventful day. While washing and reaming at 10,708’ (77’ off bottom), the 4” O.D. drill string parted at 70’.

There was an apparent defect in one of the last few joints of drill pipe that were picked up off the pipe rack. See attachment for pictures and additional details (3 pages total in attachment).

The hole has stabilized once we attained a 10.4 ppg mud weight all the way around (in the hole and in the pits). No more sluffing shale.

 

Plans are to: (1.) POOH, (2.) replace standpipe and related equipment increasing the working pressure on the mud system from 5,000 psi to 7,500 psi. With the increased mud weight and depths, being restricted to 5,000 psi working pressure is causing lower P rates. When we get back to bottom with the new bit and BHA, P Rates should be substantially higher. Estimated intermediate casing depth is 12,800’.

 

Today’s video features Mr. Devan Grubb, nighttime mudlogger for Field Geo Services, Inc. Devan assists Dr. Mike Seidensticker, the daytime mudlogger, in collecting and analyzing the drill cuttings that come across the shale shaker. He gives a detailed explanation of the procedures used for analyzing the cuttings. At the beginning of the video is a picture of a sunset on Rig 88.

 

Enjoy!
