between the zones is provided by the expanded memory based packer 10 in a fourth shifting sleeve type as shown in fig1 and 16 the sleeve can have ports some of which contain a sand control medium which may be referred to in this case as u201c sand control ports u201d and some of which do not which may be referred to in this case as u201c fracturing ports u201d in this embodiment of the apparatus 100 none of the telescoping elements would have a built in sand control medium and the sleeve shifts to selectively place either the u201c sand control ports u201d or the u201c fracturing ports u201d over the telescoping elements this shifting sleeve 16 is a rotationally shifting solid walled sleeve having a plurality of ports 24 26 a first plurality of the ports 26 the sand control ports have a sand control medium incorporated therein while a second plurality of ports 24 the fracturing ports have no sand control medium therein the sleeve 16 shifts rotationally to position either the fracturing ports 24 or the sand control ports 26 in front of the telescoping elements 12 fig1 shows the fracturing ports 24 of the sleeve 16 positioned in front of the elements 12 for pumping of proppant laden fluid into the formation fig1 shows the sand control ports 26 of the sleeve 16 positioned in front of the telescoping elements 12 for injection or production of fluid through the elements 12 in this embodiment all of the telescoping elements 12 have an open central bore none of the telescoping elements has a built in sand control medium isolation between the zones is provided by the expanded memory based packer 10 it should be understood that a rotationally shifting type of sleeve as shown in fig1.
