Product Description
Diamond Drilling Coring Barrel Overview
ROSCHEN conventional diamond drilling coring barrels are engineered for reliable rock sample acquisition in exploration drilling applications. Available in standard lengths of 1.5 meters (5 feet) and 3.0 meters (10 feet), these complete core barrel systems deliver consistent performance across various geological formations.
Conventional Coring Systems
Conventional coring involves drilling and retrieving rock samples by removing the complete rod string and core barrel assembly from the hole. While more time-consuming than wireline coring methods, this approach provides reliable core recovery in diverse drilling conditions.
Available Sizes & Standards
ROSCHEN offers conventional coring systems in DCDMA sizes B, N, H, and P. Optional triple tube designs enhance core recovery in soft or highly fractured formations.
Core Barrel Assembly Types
Standard (V) Core Barrels
Recommended for most common coring applications, available in DCDMA sizes B, N, H, and P.
Thin Kerf (V2) Core Barrels
Designed to provide larger core samples while maintaining the same hole size. Currently available in N size with additional sizes available upon request.
Triple Tube (V3) Core Barrels
Utilize split liner technology for superior sample recovery in soft or highly fractured formations. Available in N, H, and P sizes.
