Rigscope International's
Annular Protector Tool (APT)
Rigscope International’s Annular Protector Tool (APT) sets a new standard for wellbore safety in deepwater drilling and completions. This innovative solution addresses the specific challenges of deepwater operations.
Wellbore Management Understanding and Management
As deepwater wells become more complex, with increasing water and wellbore depths, the need for advanced technology is more critical than ever. From drilling to completions, simple and effective solutions are essential. Consider these key factors during the completion phase:
-
Wellbore Displacement: A successful completion starts with proper wellbore displacement. This step sets the foundation for overall success. RigScope is the only provider of technology that enables a two-stage displacement process while ensuring the three critical steps:
-
Rotation
-
Reciprocation
-
Circulation

-
Fracture Treatment: After wellbore displacement, removing debris is crucial. A proper frac treatment significantly impacts well performance. A subpar treatment will directly affect production output.
-
Service Tool Positioning: One of the biggest challenges is accurately positioning service tools due to annular drag in the subsea BOP annular. When the annular elastomer closes tightly around the work string, visibility below the closed annular is lost, leaving the tool operator with no way to confirm positioning.
-
APT’s Unique Design: APT’s proprietary work string eliminates tool joints, reducing operational challenges.
-
Dynamic Seal System: APT’s proprietary dynamic seal system minimizes annular elastomer drag, which can be a major issue, especially when stripping downward under pressure. APT has successfully completed this task under 8,000 PSI in the annulus, making it the only known technology capable of performing this operation reliably.

Reducing Non-Productive Time
Non-Productive Time (NPT) is a major challenge in deepwater drilling, where equipment wear, delays, and pressure misinterpretation can cause costly disruptions. The Annular Protector Tool (APT) significantly reduces NPT by delivering real-time, precise weight readings and enabling smooth, safe work string manipulation.
Recently, in a Green Canyon eight-well development, the APT eliminated all NPT related to annular drag, allowing operations to continue without interruption, even under high annulus pressures.
Real-World Applications and Benefits
APT technology has enabled major advancements, including shifting tools under pressure, completing multi-zone fracking in a single trip, and stripping in hundreds of feet of workstring post-frac—all without risking damage to the ABOP. It delivers the precision and reliability required for complex operations, ensuring rigs operate safely and efficiently under extreme conditions.
How the APT Enhances Deepwater Drilling Operations
The APT tool effectively addresses annular drag and is rated for up to 10,000 psi annular pressure with minimal drag and 15,000 psi internal work string pressure, allowing operators to manage high pressures with confidence. Traditional open BOP systems rely on human reaction times during an influx, increasing the risk of delays and well control incidents. The APT tool mitigates these risks by creating a dynamic seal that reduces the likelihood of riser gas unloading events, enhancing safety for personnel and the environment.
