Systems and methods for reducing unwanted water and/or gas intrusion into a hydrocarbon production wellbore. The system includes a treatment injection tool for injecting a treatment agent into portions of the formation surrounding the wellbore and a tunneling tool for forming one or more tunnels within the formation. Sensors provide real-time information about wellbore parameters during treatment so that wellbore analysis can be conducted.

The disclosure relates to a method of delaying viscosification of a well treatment fluid within a well or within a subterranean formation penetrated by a well by introducing into the well a hydratable viscosifying agent of particulates having a minimum of 40% retention on a 60 mesh screen and a minimum of 1% retention on a 20 mesh screen.

A method and an apparatus for sealing perforations or cracks found in an oil well casing. The apparatus includes a hydraulic cylinder with an oil supply section at one end and a rod at another end, a cylindrical liner at least a portion of which is a malleable metal and a receiver, the liner with an outer diameter suitable for entry in to the well casing; and a frusto-conical wedge being disposed at a lower end of the liner and fixedly connected to the rod, the frusto-conical wedge having a section with a diameter larger than an inner diameter of the liner. The method includes lowering the apparatus into the well casing and increasing hydraulic pressure to the hydraulic cylinder sufficient to pull the frusto-conical shaped wedge into the liner providing sufficient lateral force to force sufficient liner material into the perforations or cracks of the well casing to seal the well casing wall

A method and drilling fluid additive for reducing severe fluid losses in a well, comprising a combination of granular scrap tire particles and polymer adhesive molded into a cone shape. Once in the severe loss zone, a plurality of LCMs wedge into the formation fractures and seal off the severe loss zone.
