摘要： An articulating band saw apparatus provides a frame that includes a vertically extending section having upper and lower end portions. An elevator moves between the upper and lower end portions of the frame. A first hydraulic actuator is supported on the elevator for movement therewith. A first arm provides arm end portions, the first arm supported by the first hydraulic actuator. An end of the first arm supporting a second hydraulic actuator that is spaced away from the first hydraulic actuator. The second hydraulic actuator supports a second arm. An endless band type saw is mounted on the free end of the second arm generally opposite the second actuator. The band saw is movable by articulation of the first and second actuators and resulting movement of the first and second arms. In one embodiment, the band saw is a diamond wire saw.

摘要： A method for removing filter cake from a subterranean borehole comprising drilling the borehole with a drilling fluid that includes additives to form a filter cake having an oxidation-degradable component, preferably a polysaccharide. The filter cake is contacted with a clear brine containing a mixture of a persulfate salt in a variable density brine to degrade the polymers within the filter cake. The persulfate mixture breaks down the filter cake in well bores having temperatures ranging from about 65null F. to 165null F. Concentration of the persulfate sets the pace of the reaction.
