ABSTRACT:
A wireline protection sub (70) for a directional drilling system having a bit (92) and downhole motor (90), a bent angle sub (84), a jar (74) and a wireline directional tool (94) mounted within the drill string between the jar and the bit with a conductive wireline (96) extending from the directional tool to a surface location, wherein the wireline protection sub comprises a landing member (110) having a longitudinal passage and a stop member (130) operable to connect to the wireline (96) and engage the landing member (110) to support the wireline within the directional drilling string above the jar (74) to minimize coiling of the wireline adjacent the jar and reduce the tendency of the jar to kink or break the wireline during dynamic action of the jar.
