Abstract
A setting module for setting a packer assembly in a wellbore can include a motor, a sensor, and an electronic control device. The sensor can detect pressure of fluid from a surface of the wellbore in an inner diameter of the setting module and output detected pressure to an electronic control device. The electronic control device can detect a triggering pressure sequence of the fluid from the surface and can, in response to detecting the triggered pressure sequence, output a command to the motor to drive a pump to cause a slip to move for setting the packer assembly.
Claims20
A setting module for setting a packer assembly in a wellbore, the setting module comprising:
- a motor;
- a sensor to detect pressure of fluid from a surface of the wellbore and output detected pressure to an electronic control device;
- and
- the electronic control device to detect a triggering pressure sequence of the fluid from the surface and to, in response to detecting the triggered pressure sequence, output a command to the motor to drive a pump to cause a slip of the packer assembly to move into a pre-set configuration in which the slip contacts a wall of the wellbore prior to the packer assembly setting in the wellbore via a mechanical setting force upstream in the wellbore from the packer assembly, wherein the pressure of the fluid from the surface of the wellbore is detectable by the sensor in an inner diameter of the setting module.
A method comprising:
- receiving, via a sensor of a setting module of a packer assembly, a triggering pressure sequence from a surface of a wellbore by detecting the triggering pressure sequence in an inner diameter of the setting module;
- pre-setting, via the setting module, a mechanical slip assembly by using the triggering pressure sequence to output a command to a motor to drive a pump to cause a slip of the mechanical slip assembly to move to contact a wall of the wellbore in a pre-set configuration of the packer assembly that is prior to the packer assembly setting in the wellbore;
- actuating, via the packer assembly and in response to receiving a mechanical setting force upstream in the wellbore from the packer assembly, the mechanical slip assembly for performing a setting operation in the wellbore;
- and
- retracting, via the packer assembly and in response to having the mechanical setting force removed from the packer assembly, the mechanical slip assembly for performing an unsetting operation in the wellbore.
An assembly comprising:
- a packer assembly;
- one or more slips;
- and
- a setting module comprising:
- a motor;
- a sensor to detect pressure of fluid from a surface of a wellbore and output detected pressure to an electronic control device;
- and
- the electronic control device to detect a triggering pressure sequence of the fluid from the surface and to, in response to detecting the triggered pressure sequence, output a command to the motor to drive a pump to cause a slip of the packer assembly to move into a pre-set configuration in which the slip contacts a wall of the wellbore prior to the packer assembly setting in the wellbore via a mechanical setting force upstream in the wellbore from the packer assembly, wherein the pressure of the fluid from the surface of the wellbore is detectable by the sensor in an inner diameter of the setting module.
