Covering: This industry research report segments the global drill collars
market by raw material (standard steel drill collar
and non-magnetic alloy drill collar
), by design (spiral and slick), by application (offshore and onshore), and by geography (Americas, APAC, and EMEA).
com)-- Global drill collar
market is expected to witness considerable growth over a foreseeable period owing to increasing energy demand along with surging drilling and E&P activities globally.
GHD005 halted prematurely after drilling reveals historical drill collar
data survey omissions
Weighted drill assay results, assay highlights and drill collar
information are tabulated rein.
The company has drilled the first hole 50 metres south of MAY11-07 to test for mineralisation at a greater depth, while the next two holes were drilled 50 metres to the east and 50 metres to the west of the drill collar
A drill collar
is the heavy tubular connector between a drill pipe and a drill bit.
The drill collar
was declined steeply west due to excess lift previously encountered in the Bortala Formation.
A resistivity anomaly located east of the SN12-01 drill collar
suggests that a northern extension of the strong silicification and gold mineralization encountered in SN12-04 could occur further to the east of, and have been missed by, SN12-01.
Gravity infill and modeling of this anomaly and further electrical geophysics will be undertaken to refine a drill collar
HST components," Cornwall continued, "are manufactured to an exacting standard of the highest quality, low magnetic signature material in order to ride within the nonmagnetic drill collar

DeLuco said the crossing started with an 8-inch pilot bore that was drilled with a standard drill bit and 191/2-pound drill collar
for about 3,000 feet of the bore.
