Paper: The LanceSM Formation Penetrator System

This paper discusses the new, patented Penetrator Tool System which utilizes the principle of high pressure jet cutting to produce clean tunnels up to 10 ft. into formation rocks. Both the downhole system and the surface pumping equipment are described. The theory of jet cutting of rocks is discussed and some empirical data are provided on penetrating hydrocarbon reservoir rocks. The effects of by-passing near wellbore formation damage and providing short, unobstructed drainage channels from the reservoir are reviewed. Various applications of the Penetrator System in new well completions, recompletions, and workovers of older wells are outlined and case histories are presented illustrating where production or injection enhancement has been achieved.
