Conventional Coring Systems: 

Conventional coring is a method of drilling and acquiring rock samples. To retrieve the core samples, the complete rod string and core barrel assembly has to be removed from the hole. Conventional coring is much more time consuming than wireline coring, as each rod has to be removed from the hole individually, then lowered back into the hole to continue to advance the boring and collect the next core sample. 
 

ROSCHEN offers conventional coring systems in DCDMA sizes B, N, H, and P. Optional triple tube designs are available to enable core recovery when drilling in soft or highly fractured formations.

Conventional Head Assemblies:

ROSCHEN offers conventional coring systems in DCDMA sizes B, N, H, and P. 

Conventional Core Barrel Assemblies: 

ROSCHEN offers conventional barrel assemblies in all standard DCDMA sizes. Optional thin kerf and triple tube systems are available to optimize productivty and core recovery in a variety of formations.

Standard (V) - our standard conventional core barrel assemblies are recommended for most common coring applications, and available in DCDMA sizes B, N, H, and P (call for A size systems).
 

Thin Kerf (V2)- thin kerf conventional core barrels are designed to allow for a larger core sample while mainting the same hole size. The conventional thin kerf barrel is available in N size (call for additional sizes).
 

Triple Tube (V3) - triple tube conventional core barrels use a split liner to enable sample recovery in soft or highly fractured formations. Split barrel assemblies are available in N, H, and P sizes.

Conventional Coring

Conventional coring consists of a core barrel attached to drill rods (AW-1 ¼ OD or NW-2” OD) that cores 10 ft. per run.  The barrel is then pulled and disassembled to retrieve the rock.  You then re-assemble the barrel and continue.
