Conventional coring is acquisition and recovery to surface of a continuous column of reservoir formation material. We manufacture our core bits and use special drillstrings with inner and outer barrels. You can rely on our high-quality core samples for accurate reservoir analysis while controlling core acquisition cost.
HT Series conventional coring systems
Our Hughes Christensen HT Series™ barrels address all formations and coring applications, especially high-angle and extended-reach wells. Built in 30-ft lengths, the series’ stabilized sections connect for coring runs over 600 ft. Steel, aluminum, or fiberglass inner barrels containerize core and mitigate risk.
HydroLift unconsolidated coring system
The HydroLift™ system addresses unconsolidated or friable formations. A full-closure mechanism ensures core recovery. The system also suits fractured formations with jam potential. A slick-entry feature prevents fractured core jamming.
CoreGard low-invasion coring system
The CoreGard™ low-invasion coring system coring protects against dynamic filtrate invasion. Special pilot shoes protect the core column. Face-discharge core bits force 60% to 85% of fluid flow through ports. Coring fluids with particulates inhibit filtrate invasion.
JamBuster anti-jamming system
The JamBuster™ antijamming system enables coring after jamming. Telescoping sleeves allow several jams during a run before tripping out. The tool suits formations where jamming is anticipated or acts as backup. The system increases core amount cut within financial constraints.
Gel Coring system
Noninvasive, nonreactive core gels protect from filtrate invasion or prevent inner barrel jams. The gel fills inner barrel before running. A special piston holds gel during tripping. The core activates the piston, allowing gel to flow around and coat the core.
High-performance premium core bits are compatible with our coring technology. Our Hughes Christensen Genesis™ PDC bits’ and QuickCore™ bits’ force-balanced technology ensures stable performance. Many bits have face-discharge technology for low-invasion applications. The bits accommodate most applications and formations.
LaserCut liner system
The LaserCut™ liner system containerizes core material during coring. The system offers enhanced safety features, rig floor core handling, and one-piece liners for splitting at surface enabling rapid core examination.
The SOr™ sponge liner coring system improves core sample quality to help enable more informed field development decision making while lowering data acquisition cost and NPT.
