Abstract
Downhole wet connection systems, and methods and apparatuses to provide an electrical connection between two downhole strings. In one embodiment, a wet connection system having a first electrode coupled to a load and deployed in a wellbore. The wet connection system also includes a second electrode deployed along a string deployed in the wellbore and proximate to the first electrode. Further, the first electrode and the second electrode form a wet connection to transmit alternating current from the second electrode to the first electrode.
Claims19
A downhole wet connection system, comprising:
- a first electrode deployed in a wellbore, the first electrode being coupled to a load deployed in the wellbore;
- a second electrode deployed along a string deployed in the wellbore and proximate to the first electrode, and
- a power convertor deployed proximate to the first electrode and operable to convert the alternating current flowing from the first electrode to direct current,
- wherein the first electrode and the second electrode are operable to form a wet connection to transmit alternating current from the second electrode to the first electrode.
A method to form a downhole alternating current wet connection,
- the method comprising:
- deploying a first electrode in a wellbore, the first electrode being coupled to a load deployed proximate to the first electrode;
- deploying a string having a second electrode proximate to the first electrode;
- determining an alignment of the first electrode with respect to the second electrode;
- establishing a wet connection to connect the first electrode and the second electrode when the first electrode and the second electrode are aligned;
- transmitting an alternating current from the second electrode, across the wet connection, to the first electrode to power the load;
- and
- converting the alternating current flowing from the first electrode to direct current.
An apparatus to form a downhole alternating current wet connection, comprising:
- a first electrode deployed in a wellbore;
- a second electrode deployed along a string and positioned proximate to the first electrode;
- a spring loaded electrical connector operable to directly connect the first electrode and the second electrode to establish a wet connection between the first electrode and the second electrode, wherein an alternating current flows across the wet connection;
- a power convertor deployed proximate to the first electrode and operable to convert the alternating current flowing from the first electrode to direct current;
- and
- a controller operable to modulate at least one of a frequency, phase and amplitude of the alternating current to provide at least one of power and data transmission to a load deployed proximate the first electrode.
