This paper describes a series of experiments to measure the penetration depth with time of shaped charge jets as used in the oil industry to perforate well‐liners. Targets comprised steel (simulating the well‐liner), cement (representing the grout surrounding the liner) and Berea sandstone (in the form of cores) as the oil‐bearing material. Results indicated cratering velocities of about 2000 m/s through the sandstone. Jet slow‐down was very gradual and performance was found to be consistent with the behaviour of shaped charges penetrating materials such as those used in military armour.
