    Victor A. Schmidt, Drilling Engineering Editor

    JJets are a common technology in the oil patch. According to the Wikipedia dictionary, a jet is “a coherent stream of fluid that is projected into a surrounding medium, usually from some kind of a nozzle or aperture.” In drilling, the concentrated pressure of downward-directed jets is useful for loosening lightly consolidated rock ahead of the bit and for cleaning cut rock from the bit face. When perforating a well, it is the power of the shaped charge’s explosive jet, directed perpendicular to the well, that opens a connection between the wellbore and the reservoir. In well maintenance, sideward-directed fluid jets are useful for cleaning scale and other deposits from the inside of tubing and other in-well equipment. Taking a cue from the growing use of horizontal drilling, a relatively new form of jetting is helping to extend the life of older vertical wells.
