Retina

Innovative at-bit data for high-resolution borehole images

Retina™ at-bit imaging system is a groundbreaking technology that converts measurements taken at the drill bit into high-quality borehole images. For the first time, high-frequency cutter force data can be translated into detailed borehole images.

How it improves performance

Using a recording mode system, a PDC drill bit is tailored with the latest design, architecture, and cutter technologies to accommodate sensors for measuring forces at the bit face. Retina system captures formation details to visualize and characterize layers, bedding dips, thin beds, fractures, and textural variations without interference from any type of drilling fluid. The raw data is processed to create a high-resolution borehole image for formation characterization and rock properties qualification.

• Onshore and offshore 
• Formation characterization
• Well planning and field development
• Any bottomhole assembly (BHA), rotary steerable system (RSS), motor, or drive system

• Provides unprecedented insights into formation geology and rock properties
• Works with any drilling fluid composition
• Enhances well planning and field development
• Characterizes formations in challenging environments before borehole damage occurs
• Requires no change to drilling operations, extra runs, or additional tools 
• Deploys and operates easily and simply

With industry-leading image resolution, the Retina system measures high-frequency cutting forces against azimuth with integrated sensors in the cutting structure of the PDC bit. The system utilizes optimal bit architectural design for data collection and sensor reliability. After the run, an image is created for formation interpretation, geological model update, and description of formation features not yet available due to technical limitations such as hole size and mud type.
