Abstract
A downhole drilling tool for forming a port through a tubular sidewall. The tool comprises a body with a longitudinal axis, at least one anchoring member and a drilling member. Both members are radially movable between retracted and extended positions by pressurised hydraulic fluid from a common downhole supply. The anchoring member stabilises the tool against the tubular wall, and the drilling member, arranged substantially perpendicular to the tool axis, is rotatable to cut through the sidewall. Fluid communication between the members ensures they experience the same hydraulic pressure. The tool may be powered by a battery-driven motive assembly that also pressurises the hydraulic fluid and provides torque for rotation. A method of drilling through a tubular sidewall using the tool.
