CoreBits (CB): Reliable Core Recovery for Critical Decisions
Core samples provide the most direct and reliable information about subsurface formations, and the CoreBits (CB) series from VBM ensures that this critical data is recovered with the highest possible quality. Unlike drilling cuttings or wireline log interpretations, whole core samples provide a direct physical sample of the reservoir rock that can be subjected to comprehensive laboratory analysis, yielding porosity, permeability, fluid saturation, mechanical properties, and detailed geological characterization.
The CB series utilizes PDC cutting technology to provide a smooth, controlled cutting action that minimizes core disturbance. Traditional natural diamond core bits can generate excessive vibration that damages the core, particularly in softer formations. The PDC cutters on the CB series provide aggressive yet controlled cutting that preserves the natural fabric of the formation, maintaining representative fluid saturations and mechanical properties that are essential for accurate reservoir modeling and completion design.
Core recovery rate is the primary performance metric for any coring operation, and the CB series is designed to maximize recovery in all formation types. The inner gauge and throat geometry are optimized to allow the core column to enter the core barrel smoothly, preventing jamming that can cause core grinding, rubblization, or total loss. The hydraulic design directs fluid flow to cool and clean the cutting structure while protecting the core column from erosion.
VBM Middle East supplies CoreBits (CB) in all standard core barrel sizes, with custom configurations available for specialized applications. Whether you are planning a conventional coring program in a new exploration well or recovering critical samples from a development well, our team can recommend the optimal CB design for your formation and equipment.
