In one embodiment, a perforating gun 56 may create tunnels 58 in a formation 60, the firing of the gun generating an overbalance condition by means of which treatment fluid from an applicator tool 62 is driven into the tunnels - either from a pressurised chamber 63 upon opening a port 64 using a time release mechanism 66, or from a shell 57 with chamber 59 of treatment fluid surrounding the perfor...

A method and apparatus for improving reservoir communication includes, in o ne arrangement, causing creation of tunnels in surrounding formation of a well interval, and applying treatment fluid to the tunnels. A local transient underbalance condition is created in the well interval after creation of the tunnels in the formation and application of the treatment fluids.
