Our standard core barrels feature a simplicity of design and precision of machining that have been trademarks of our products for over 50 years.

Inner core barrel platforms
Reservoir Group offers a range of standard inner barrels for all of our core barrel platforms. Unlike our Thin Sleeve System (TSS), which has reusable components, these inner barrels are disposable, which reduces the amount of handling and disturbance to the core itself when recovered on surface
Core heads
Reservoir Group offer a comprehensive range of core heads, exhibiting numerous unique features that enhance core quality and coring performance.
Gyrohead
The Gyrohead is the upper portion of Reservoir Group’s double bearing system within our CP Core Barrel family.
Outer core barrel platforms
The Reservoir Group coring concept has been specifically designed to enable the retrieval of longer, higher quality cores. This concept has been built on two distinct families of core barrel platforms that offers complete coverage for the full spectrum of coring applications and hole sizes.
Split lay down sub
Reservoir Group Split Lay-Down Sub [SLDS] assemblies allow for quick and efficient handling of long coring runs. Their design eliminates inner barrel rotation during lay-down operations which leads to improved core quality over traditional lay-down subs.
