Abstract
For ensuring casing and cementing quality, mud cake removal is essential. Various problems like stuck pipe take place because of the presence of mud cake. Mechanical methods of water jetting and chemical methods by means of acids, oxidizers, chelating agents and enzymes are currently employed for mud cake removal. However, water jetting can cause water blockage problems. Also, Mud cakes of different permeability will be removed unevenly by same intensity water jets. Acids and oxidizers are very reactive but non- specific species, imposing several post perforation problems and formation damage.
As an alternative, we propose a new method/device in this study with the usage of nanobots and laser grinding. The nanobots, placed in carrier, can be sent through drill string into the drill bit from where they can be deployed in all directions into the targeted zone. These non-adherent and self-propelled nanobots will move through the vertical permeability of the mud filtrate and would interpret the petro physical properties of the mud filtrate.
