Abstract

A deployment method and set of alternative tools for deploying, exchanging, and repairing an Electric Submersible Pump (ESP) and pipe strings utilizing a lubricator and standard pressure control equipment (valves, Blow Out Preventers); this method permits a rig less deployment of an ESP with well control maintained using a short length lubricator and standard pressure containment tools. This method defines a specific set of tools to be incorporated in the method to achieve the assembly of the ESP at surface and deployment in a single run to set the ESP at the pumping depth. This method facilitates the orientation and alignment of the terminals of the ESP motor and gauge and creates a pressure barrier through the ESP string during makeup and break out of the ESP.

Dependent claims

A deployment method for an Electric Submersible Pump (ESP) using a head and a base group with a specific set of tools for exchanging the ESP and a string in a lubricator and a low-profile docking station for Oil Wells comprising:

First, placing a wireline system in place at a well for the workover and next performing a set of the following steps:
Step 1:
Close valves (320, 330) and bleed pressure (315);
Step 2:
Break out lubricator (310);
Step 3:
Lower running tool (400) to latch on ESP component or other unit;
Step 4:
Lift tool string (390) into lubricator (310);
Step 5:
Make up lubricator (310) using a set of tools;
Step 6:
Open pressure equalization valve (330) and open master valve (320);
Step 7:
Lower tool string (390) and mate to motor (30);
Step 8:
Lift tool string (390) for final makeup
Step 9:
Close BOP ram (350), close pressure equalization valve (330), and bleed pressure (315);
Step 10:
Open access panel (500) on lubricator (310), decouple and make up collar (550), and close access panel (500);
Step 11:
Close bleed valve (315), open pressure equalization valve (330), and open BOP (350);
Step 12:
Repeat Steps 1 through 11 as needed;
Step 13:
Lower tool string (390) to rest on shoulder (450) and release running tool (400);
Step 14:
After complete assembly of ESP string, lower the ESP string to the pump setting depth and mate the ESP motor connector to the docking station in the borehole.
Step 15:
Release running tool string from ESP and pull to surface.
Step 16:
Remove the wireline equipment from the well and re-start the operation.
Step 17:
Remove the ESP from the well by reversing the steps of the described installation.
wherein the manner to exchange the ESP and the at least one string in the lubricator and the low-profile docking station are enabled using improved tools including a running tool with an integral sealing plug, and a set of alignment guides, and the specific set of tools.
