Abstract

A method for establishing a remote connection between a hydraulic fracturing head and hydraulic fracturing tubing line that is not reliant on personnel to manually establish a connection between the hydraulic fracturing tubing line and hydraulic fracturing head. The hydraulic fracturing tubing head is elevated above and connected to a wellbore. Next, a hydraulic fracturing tubing line is elevated to the hydraulic fracturing tubing head by connecting lines which are guided by a set of dual roller assemblies. The hydraulic fracturing tubing line is equipped with a male connector, configured to fit within a latching receptacle, which is installed on the hydraulic fracturing head. Once the male connector is seated in the latching receptacle, hydraulic pressure release closes latches on the latching receptacle, establishing a fluid connection. Once connected, hydraulic fracturing can begin.

Claims (17)

1 . A method for attaching a hydraulic fracturing tubing line to an elevated hydraulic fracturing head, the method comprising:

attaching a plurality of connecting lines to a lifting saddle coupled to the hydraulic fracturing tubing line;

via the connecting lines, vertically lifting a first connector of the hydraulic fracturing tubing line to engage with a second connector of the elevated hydraulic fracturing head; and

remotely engaging the first connector and the second connector while the connecting line supports the hydraulic fracturing tubing line.

2 . The method of claim 1 , wherein the first connector of the hydraulic fracturing tubing line comprises a male connector.

3 . The method of claim 1 , wherein the first connector comprises a female connector.

4 . The method of claim 1 , further comprising attaching the elevated hydraulic fracturing head to a wellbore.

5 . The method of claim 1 , wherein the connecting line comprises a chain.

6 . The method of claim 1 , further comprising guiding the connecting line via an assembly of rollers coupled to the elevated hydraulic fracturing head.

7 . A method for providing fluid to a wellbore, the method comprising:

via a plurality of connecting lines attached to a lifting saddle coupled to a hydraulic fracturing tubing line, vertically lifting a first connector of the hydraulic fracturing tubing line to engage with a second connector of an elevated hydraulic fracturing head in fluid connection with the wellbore;

remotely engaging the first connector of the hydraulic fracturing tubing line and the second connector of the elevated hydraulic fracturing head while the connecting line supports the hydraulic fracturing tubing line;

establishing a fluid connection between the hydraulic fracturing tubing line and the elevated hydraulic fracturing head; and

providing fracturing fluid from a fluid source in fluid connectivity with the hydraulic fracturing tubing line to the wellbore.

8 . The method of claim 7 , wherein the first connector of the hydraulic fracturing tubing line comprises a male connection.

9 . The method of claim 7 , wherein the first connector of the hydraulic fracturing tubing line comprises a female connection.

10 . The method of claim 7 , further comprising guiding the connecting line via an assembly of rollers coupled to the elevated hydraulic fracturing head.
