Filed:

Dec 22, 2010

Appl. No.:

13/518263

Inventors:

Ruben Martinez - Houston TX, US
Sarah Blake - Sugar Land TX, US

International Classification:

E21B 33/12
E21B 23/08
E21B 47/06

US Classification:

16625004, 166 853

Abstract:

A hydraulic setting tool. The tool is configured to allow hydraulic setting of a bridge plug, packer or other radially expansive mechanical well isolation mechanism. Wireline or slickline deployment may be utilized. In either case, parameters of the setting application may be recorded. In the case of wireline deployment such parameters and downhole data may be monitored in real-time allowing an operator to make intelligent setting application adjustments as necessary.

Abstract:

A method () and an assembly () for milling an obstruction disposed within a wellbore (W) includes a milling module () having a motor () rotating a milling bit (), a first electronics cartridge () for controlling the motor based upon a motor torque value, a tractor module () for engaging with the wellbore and providing a push force against the wellbore to urge the milling assembly in a direction of the milling bit, and a second electronics cartridge () for controlling a push force value of tractor module. The method involves rotating the milling bit () and engaging the tractor module with the wellbore (), and adjusting, iteratively, the operation () based on a calculated torque value and a calculated push force value to maintain the calculated values at around a target torque value and below a push force limit value ().
