Abstract: A technique facilitates both a fracturing operation and a subsequent production operation in, for example, a geothermal well system. According to an embodiment, a geothermal a well completion is deployed downhole into a wellbore. The geothermal well completion comprises a tubular section deployed in a well zone and having a fracturing port and a production port. Additionally, a shiftable tool is disposed in the tubular section. The shiftable tool comprises a sleeve system which is selectively shiftable between a plurality of operational flow positions. In some embodiments, a plurality of the shiftable tools may be used along corresponding well zones to facilitate fracturing of the well zones while also ensuring the outflow of production fluid has a desired balance along the plurality of well zones.

Abstract: A technique facilitates use of a frac diverter instead of a frac plug in a variety of fracturing operations. The frac diverter has a simpler and less expensive construction. Although the frac diverter may not form a seal with the surrounding casing in some applications, the frac diverter is able to sufficiently restrict flow of fracturing fluid to enable a successful fracturing operation. The frac diverter may comprise arrangements of at least one cone, at least one slip ring, and at least one corresponding sub which work in cooperation with a flow restricting element. The flow restricting element may comprise various types of rings, e.g. sealing element rings, able to sufficiently restrict flow of fracturing fluid past the frac diverter.
