radially from the tool 17 by varying which set of pistons is extended or retracted eight settings can be obtained with the following sequence by way of example 1 pistons set 1 full gauge set 2 and 3 under gauge tool face 1 x 2 pistons set 1 and 2 full gauge set 3 under gauge tool face 2 x 60 degrees 3 pistons set 2 full gauge set 1 and 3 under gauge tool face 3 x 120 degrees 4 pistons set 2 and 3 full gauge set 1 under gauge tool face 4 x 180 degrees 5 pistons set 3 full gauge set 1 and 3 under gauge tool face 5 x 240 degrees 6 pistons set 1 and 3 full gauge set 2 under gauge tool face 6 x 300 degrees 7 pistons set 1 2 and 3 full gauge tool face 7 0 degrees 8 pistons set 1 2 and 3 under gauge tool face 8 180 degrees tool face increment is 60 degrees initial value u201c x u201d of the tool face depends on the angular position of the sliding sleeve in the worst case the difference between desired tool face and actual tool face is 30 degrees with additional blades the number of setting cycles would increase as a function of the equation where s is the total possible number of settings and n is the number of blades the number s can be reduced with the realization that all combinations are not necessary for down hole control when dealing with more than 3 blades.
