Abstract
A system for operating downhole equipment in a well includes a drive shaft extending from a surface of the well to a downhole location. A motor is positioned at the surface and is operably connected to the drive shaft to selectively rotate the drive shaft. A lift system is positioned at the surface and is operably connected to the drive shaft to axially lift and lower the drive shaft.
Claims22
A system for operating downhole equipment in a well comprising:
- a drive shaft extending from a surface of the well to a downhole location;
- a motor positioned at the surface and operably connected to the drive shaft to selectively rotate the drive shaft;
- and
- a lift system positioned at the surface and operably connected to the drive shaft to axially and repeatedly lift and lower the drive shaft;
- wherein each time a substantial reduction in fluid flow at a portion of the well is desired, the lift system lifts or lowers the drive shaft to cause the substantial reduction in fluid flow.
A method for removing liquid from a well having a producing formation, the method comprising:
- positioning a drive shaft within the well such that the drive shaft extends from a surface of the well to a downhole location;
- lifting or lowering the drive shaft from the surface of the well to activate an isolation device that substantially reduces gas flow from the producing formation at the downhole location;
- repeating the lifting or lowering of the drive shaft each time a substantial reduction in gas flow at the downhole location is desired;
- and
- removing the liquid from the downhole location each time the substantial reduction in gas flow occurs.
A system for removing liquid from a well having a producing formation, the system comprising:
- drive means for transmitting power from a surface of the well to a downhole location;
- means for repeatedly lifting or lowering said drive means disposed at the surface of the well;
- and
- means for moving the liquid from the downhole location;
- wherein each time a substantial reduction in gas flow from the producing formation at the downhole location is desired, the means for repeatedly lifting or lowering said drive means lifts or lowers the drive means to cause the substantial reduction in gas flow to the surface of the well, said means for moving disposed at the downhole location.
