| titleOfInvention | Downhole Release of Friction Reducers in Gravel Packing Operations |
| abstract | A method of introducing friction reducing agents within a wellbore penetrating a subterranean formation during a gravel packing operation is accomplished by providing a length of tubing located downhole within the wellbore for conducting fluids within the wellbore through the tubing during circulating of gravel packing fluids introduced from the surface within the wellbore. At least a portion of the tubing is surrounded by a screen for screening out particulate matter during the gravel packing operation. An annular space is defined between an interior of the screen and the exterior of the tubing. A friction reducing agent is dispensed from a dispensing apparatus that locates downhole with the tubing. The dispensing apparatus includes a housing and a chamber disposed within the housing that has one or more outlets that open into the annular space defined by the screen and tubing for dispensing the friction reducing agent. The dispensing apparatus further includes a piston and a trigger mechanism for actuating the piston. When the trigger mechanism is activated to actuate the piston, the friction reducing agent is dispensed through the one or more outlets at a position downhole remote from the surface during the circulating. |
