Abstract
A system for disengaging a power supply at the surface of a well from a downhole assembly having a pump for pumping fluid in the well to the surface thereof. A captured spline assembly interposed in the rod string, selectively connected to the downhole assembly to provide torsional drive.
Claims9
In a well for the capture of subterranean fluids in which a power supply located at the surface of the well drives a downhole assembly for pumping the fluid in the well to the surface through a captured spline assembly,
- a rod string depending from, and connected with, the power supply and engaged with the downhole assembly;
- a system for the connection and release of said rod string from said downhole assembly, said downhole assembly having a receiver, said receiver standing upwardly therefrom, said receiver encasing a captured spline assembly to provide a torsional connection thereto.
In a well for the capture of subterranean fluids in which a power supply located at the surface of the well dries a downhole assembly for pumping the fluid in the well to the surface,
- a rod string depending from, and connected with, the power supply and engaged with the downhole assembly;
- a system for the connection and release of a rod string from a downhole assembly, said downhole assembly having a receiver, said receiver standing upwardly therefrom, said receiver housing a captured spline assembly;
- an on-off tool mounted in said rod string, said on-off tool being selectively separable to disengage said captured spline assembly from said power supply as needed.
