DISSOLVABLE BALLAST FOR UNTETHERED DOWNHOLE TOOLS - A simplified explanation of the abstract
This abstract first appeared for US patent application 17752176 titled 'DISSOLVABLE BALLAST FOR UNTETHERED DOWNHOLE TOOLS
Simplified Explanation
- The patent application describes an apparatus that includes a ballast designed to connect to a downhole tool used in oil and gas drilling. - The ballast is made of a composite material consisting of two parts: a first part containing metallic particles and a second part made of a polymer matrix. - The first part provides weight to the downhole tool when it is attached, allowing it to be lowered into a well in the ground. - The second part of the composite material is designed to dissolve when exposed to downhole fluid under specific conditions. - When the second part dissolves, it releases the metallic particles from the first part, allowing them to be separated from the dissolved polymer matrix. - This innovation allows for controlled release of the metallic particles, which may have specific properties or functions, in the downhole environment.
Original Abstract Submitted
An apparatus includes a ballast that is configured to couple to an untethered downhole tool. The ballast includes a composite material. The composite material includes a first portion and a second portion. The first portion includes metallic particles. The first portion is configured to, while the ballast is coupled to the untethered downhole tool, provide weight to the untethered downhole tool to lower the untethered downhole tool into a well formed in a subterranean formation. The second portion includes a polymer matrix. The metallic particles of the first portion are distributed throughout the polymer matrix of the second portion. The second portion is configured to dissolve in response to being exposed to downhole fluid within the well at specified downhole conditions, thereby releasing the metallic particles of the first portions from the polymer matrix that has dissolved.
