A wireline drilling system for the hydrocarbon exploration and production industry incorporating a drilling cuttings removal system which acts to remove and store cuttings displaced by a drill bit during drilling operations. The cuttings removal system may employ a screw member having a tapered lower portion and a narrow upper portion to transport drilling cuttings to a cuttings basket and distribute the cuttings therein. Embodiments of the invention include an integral tractor to progress the wireline drilling system and provide weight-on-bit, as well as assist in retrieval of the wireline drilling system if the tool should become stuck. |
