Abstract
A system that is usable with a well includes a tubular string, which includes a jetting sub. Fluid is communicated outside an annular region that surrounds the string to a first zone of the well for purposes of treating the first zone. During the communication of the fluid through the annular region, fluid is communicated through the tubing string and through the jetting sub to perforate a second zone of the well.
Claims19
A method usable with a well, comprising:
- treating a first zone of the well;
- and
- during the treating, perforating a second zone of the well;
- wherein the perforating comprises:
- providing a coiled tubing string or a jointed tubing, the coiled tubing string or the jointed tubing having multiple jetting subs spaced apart along a length of the coiled tubing string or the jointed tubing and associated with multiple zones of the well, one of the jetting subs being associated with the second zone;
- and
- deploying an object in the coiled tubing string or the jointed tubing to block fluid communication in the coiled tubing string or the jointed tubing below the one jetting sub associated with the second zone to cause fluid communicated through the coiled tubing string or the jointed tubing to exit the string or the jointed tubing at the one jetting sub associated with the second zone.

A system usable with a well, comprising:
- a pump to communicate a treatment fluid into the well to treat a first zone of the well;
- and
- a string comprising a plurality of perforating devices that comprise a plurality of jetting subs, the plurality of perforating devices spaced apart along the length of the string adapted to be activated in a sequence to perforate different zones without requiring relocation of the string and to perforate a second zone of the well while simultaneously allowing the passage of the treatment fluid to the first zone,
- wherein each of the jetting subs is adapted to be activated to communicate fluid from the sub to perforate a surrounding region of the well in response to a differently-sized object blocking fluid communication downstream of the jetting sub.
