By using the Excite tool with gauges, you receive a road map that shows which clusters respond to treatments, which clusters need refracturing, and which clusters to skip additional treatments. This drastically reduces operational risk while also focuses the resources on the parts of the lateral that need it the most – saving time and reducing cost for the life of the well.

The Comitt EXCITE System with downhole pressure gauges provides
your downhole set of eyes
Low pressure readings can be identified as a low resistance fracture (i.e. a successful fracture) or a perforation that is communicating with an adjoining perforation because of an insufficient cement seal outside the casing. With a gauge above and below the pair of packers, you can even tell which perforation is communicating with the tested perforation.
Cross flow between clusters can be determined prior to pumping proppant laden fluid and thereby significantly reduce operational risk. For each cluster, gauges are installed above, between, and below the packers to give precise injection pressure readings (BHP) for each perforation cluster. This pinpoints the location of clusters with cross communication behind the pipe.
The Excite System Advantage
Use downhole pressure data to identify previously untreated clusters
Reduce treatment cost by identifying which clusters to treat
Identify cross-communicating clusters up front and eliminate risk of getting stuck
Significantly improve effectiveness of treatment by focusing all resources where it matters most

Previously untreated rock is identified based on high pressure responses, and treatments can be tailored to each individual cluster. High pressure readings indicate that the original fracture job did not penetrate the formation at that particular cluster and should be refractured. The procedure of isolating pressure gauges at each perforation provides this valuable information that cannot be attained any other way.

With this information, the tool can be resent downhole with a single run that will either acid treat or refracture each perforation. The high-pressure reading perforations will be refractured because the high pressure indicates that the initial fracture bypassed those perforations. That refracturing actually results in the first fracturing of many of those perforations because the pressure during the original fracture was absorbed by the other perforations in the stage. Perforations with cross-communication can be ignored to avoid adding sand and debris into the wellbore which can cause a stuck tool.
