Our high-strength straddle packer module acquires fluid samples and test data in the most challenging environments. Its extended deployment range ensures that critical formation information is not missed so you can gain a better understanding of your reservoir regardless of environment.


Enhanced drawdowns and in-depth investigations

As the complexities of wells continue to increase, it is more common to encounter over-pressure depleted zones in the same well—causing some reservoirs to be exposed to very high overbalances, which can make testing very challenging. The design of the high-strength straddle packer module enables high-pressure differentials to be reached for enhanced drawdowns. This capability makes mini-drillstring testing (mini-DST) and vertical interference testing (VIT) possible in high-overbalanced environments and enables faster fluid sampling in low-mobility formations.

The increased injection pressure of the high-strength straddle packer module enhances micro-frac testing capabilities in stronger formations. As a result, an extended range of formations can be investigated—overcoming testing limitations in formations that can be incredibly difficult to fracture.

The high-strength straddle packer module uses the Reservoir Characterization eXplorer™ (RCX™) service platform, which has a proven track record of reliable operations, including hostile and high-pressure/high-temperature (HP/HT) environments.
