... in the borehole transmits the P hyd to the formation that is exposed by the core barrel while coring, which would tend to displace gas (of density φ g ) deeper into the formation. However, in extremely low permeability, and with a coring process lasting only minutes, the r i in the core is negligible so...

... A&M University wireline-retrieved core barrel and latching tool. This combined approach will allow for precise core-log depth calibration and core orientation within a single borehole, and without at pipe trip, providing both time saving and unique scientific advantages. This successful test during...

... to improved equipment and more efficient operational techniques. Improvements in equipment include a basic redesign of the previous core barrels and use of a self-contained work trailer. Use of Stratapax type bits greatly enhanced core recovery while increasing drilling rates as much as ten fold. More...
