2 stage cementing to secure the annular integrity.
Difficult annulus cement operations
Cementing operations in low-pressure formations, high permeability zones, and long casing strings can be difficult with standard cement slurry, resulting in significant losses and insufficient annular integrity. To address the challenge of creating a secure and stable environment for producing wellbore fluids, a solution is to use a Steel Packer in combination with a Stage Collar as part of the casing string.
Steel Packer is a fit for basin external casing component that aims to create a seal between two sections of the annulus, effectively forming a barrier between the two sections. A stage Collar is a casing component that provides a secure connection between the casing and the annular section. Combining the Steel Packer and Stage Collar as part of the casing string will create a secure environment for a two-stage cementing operation.
Robust steel external casing packer
The packer positions above the problematic formation in a part of the hole that is stable and not likely to collapse. This packer then expands using a pressure-activated mechanism, allowing it to tightly fit the walls of the hole and provide support for the cement circulating from the stage collar to the surface. This 2 stage cementing process allows for sealing off the problematic formation and ensures that the area is properly secured and stabilized.
Our Steel Packer is incredibly durable and can withstand tough drilling operations, even in tight spaces. This reduces the risk of damage to the packer during the process. Its ability to rotate during the run-in and two stage cementing process makes it easier for the cement placement in the desired location. Furthermore, the Steel Packer has a high expansion ratio, ensuring a strong seal even in boreholes that have been partially eroded. As a result, the Steel Packer is an ideal tool for drilling operations in difficult-to-reach places.
