Systems and methods for core recovery

A system, comprising a downhole tool configured for conveyance within a borehole extending into a subterranean formation, wherein the downhole tool comprises:

• a hydraulic pump driven by a motor;
• an actuator linearly driven by hydraulic fluid received from the hydraulic pump and configured to retract a coring bit of the downhole tool;
• a sensor configured to sense a coring operation environmental factor, wherein the coring operation environmental factor is based at least in part on a measurement taken during coring;
• and
• a controller configured to execute instructions stored within the downhole tool to determine whether the subterranean formation comprises a consolidated formation or an unconsolidated formation based at least in part on the coring operation environmental factor, and to drive the actuator at an adjustable rate of retraction by regulating a flow of the hydraulic fluid based on whether the subterranean formation is determined to comprise the consolidated formation or the unconsolidated formation.
