Abstract
A system and method for retrieving materials from a wellbore includes a retrieval assembly. The retrieval assembly includes a collar, a camera, a retrieval tool, a powered swivel, a wireline side entry subassembly, and multiple stands of drill pipe. The collar includes a wireline connection. The camera is oriented towards the distal end of the retrieval assembly. The wireline side entry subassembly is attached to a stand of drill pipe. The wireline assembly connects from the retrieval assembly to a user interface at the surface.
Claims14
A system for retrieving materials from a wellbore comprising:
- a retrieval assembly comprising:
- a collar comprising a wireline connection,
- a camera oriented towards a distal end of the retrieval assembly to observe the materials to be retrieved,
- a retrieval tool,
- a powered swivel for rotating the retrieval tool,
- a wireline side entry subassembly, and
- a plurality of stands of drill pipe,
- wherein the wireline side entry subassembly is attached to a stand of drill pipe, and
- a wireline assembly,
- wherein the wireline assembly is operatively connected to the retrieval assembly via the wireline connection to enable control of the retrieval assembly via the wireline assembly from above ground.
A method for retrieving material from a wellbore comprising:
- assembling a retrieval assembly,
- running a wireline assembly through a wireline side entry subassembly and down a plurality of stands of drill pipe to operatively connect the wireline assembly to a wireline connection comprised in the retrieval assembly,
- wherein the retrieval assembly comprises the plurality of stands of drill pipe,
- wherein the retrieval assembly comprises the wireline side entry subassembly,
- running the retrieval assembly to the bottom of the wellbore,
- observing a position and condition of the material to be retrieved using a camera comprised in the retrieval assembly,
- employing a positioning technique to engage the material with a retrieval tool,
- wherein the retrieval tool is comprised in the retrieval assembly,
- wherein the positioning technique comprises:
- translating the retrieval tool along the wellbore with tension and/or pressure applied to the plurality of stands of drill pipe from a drilling rig,
- rotating the retrieval tool with a powered swivel comprised in the retrieval assembly,
- engaging the material,
- withdrawing the wireline assembly from the wellbore,
- removing the wireline side entry subassembly from the plurality of stands of drill pipe, and
- withdrawing the retrieval assembly from the wellbore along with the material, and recovering the material.
