Wireline core drilling | Epiroc US

Wireline core drilling systems are used for medium to ultra-deep boreholes, which provides the most efficient core sample extraction from the rock mass without pulling the entire drill string. The rock sample is removed from the bottom of the hole in the inner tube assembly by an overshot on a wireline cable.

To reduce hole deviation and/or increase drilling tool life, good core barrel stabilization is important. Besides the reaming shell, the locking coupling is a key component for good barrel stabilization. Standard steel locking couplings may wear prematurely in abrasive and/or broken conditions. Our diamond impregnated locking couplings with full hole body will dramatically increase the life of the tool, keeping nominal gauge for a very long time. With our components, you can drill with confidence!

DiscovOre - common problems eliminated

After a long period of development and testing of one of the most innovative breakthroughs in the industry, we are excited to offer our customers an exclusive release of our new cutting-edge line of in-the-hole (ITH) tools. Our DiscovOre head assembly and overshot incorporates design features that eliminate many of the common problems found on ITH systems used in the industry today. Our new core retrieval tooling has been field and lab tested with positive results.

Overview

Accurate reservoir analysis 

Conventional coring services include acquisition and recovery to the surface of a continuous column of reservoir formation material. Baker Hughes manufactures core bits and uses special drillstrings with inner and outer barrels. You can rely on our high-quality core samples for accurate reservoir analysis while controlling core acquisition costs. 

HT Series conventional coring systems 

Our HT Series™ barrels address all your formations and coring applications, especially high-angle and extended-reach wells. The series’ stabilized sections, built-in 30-ft (9-m) lengths, connect for coring runs of more than 600 ft (183 m). Steel or aluminum inner barrels containerize the 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, while a slick-entry feature helps prevent jams as the core enters the catcher.

CoreGard low-invasion coring system 

The CoreGard™ low-invasion coring system protects against dynamic filtrate invasion. Special pilot shoes protect your core column, while face-discharge core bits force 60 to 85% of the coring fluid through ports. 

JamBuster anti-jamming system 

The JamBuster™ anti-jamming coring system enables coring after jamming occurs. Telescoping inner core barrel sleeves mitigate the effects of core jams, eliminating unscheduled trips out-of-hole and related nonproductive time. The system therefore significantly increases the amount of core cut per run in jamming prone formations. 

Gel coring system 

The CoreGel™ system uses a viscous, noninvasive gel to protect cores from drilling fluid invasion, which can alter the chemical and physical properties of the cores. The gel fully encapsulates the core downhole to prevent contact with the drilling fluid and supports the core during recovery, surface handling, and transportation. 

Core bits 

High-performance, premium core bits are compatible with our coring technology. Our Genesis™ and Talon™ PDC (polycrystalline diamond compact) bit technologies ensure stable performance. Many bits have the face-discharge technology and can be used in combination with the CoreGard low-invasion coring system. Our bit portfolio provides features adjusted to the needs of all your applications and formations. 

LaserCut liner system 

The LaserCut™ liner system containerizes core material during coring while enabling easy access to the core at the surface. The system offers enhanced safety features, rig floor core handling, and one-piece liners for splitting at the surface, enabling rapid core examination. 

SOr sponge liner coring system 

The SOr™ sponge liner coring system improves core sample quality to help you make a more informed field development decision while lowering data acquisition costs and nonproductive time. 

CoreCare transportation 

The CoreCare™ transportation equipment ensures that the quality of the core is maintained during the handling and transportation of the core from the field to the laboratory. The optional CoreCare tracking service provides a time-based record of any shocks and temperature changes during transportation, enabling feedback for continuous improvement during the transportation process.
