| An
Associated Directional Drilling, Inc. Success Story
ADD was nearing completion
of Level 3's, 12 Duct fiber optic interduct installation under the San
Gabriel River near Taylor, Texas. As drillers neared the surface on the
oppositte side of the river, they were confronted with boulders and cobbles
of unknown size at a depth of approximately 20 feet. After several attempts
to get through--and the loss of a mud motor--a vertical rig was brought
in to determine the size of the boulder and cobble formation. Using hollow-stem
augers and continuous core methods, it was determined that there were numerous
boulders and cobbles in the formation between a vertical depth of 9-1/2
and 20 feet. ADD drilled several holes in a grid pattern over the proposed
bore path and used a high pressure injection pump to introduce cement into
the formation. After the cement had cured properly, the zone of interest
was solidified and ADD was able to drill through the zone with a mud motor,
then back-ream the entire zone with a 12-inch back-reamer thus completing
the final installation of 1245 feet of 8-inch SDR9 HDPE.
