Embodiment Construction

[0027] Example embodiments consistent with the teachings contained in this disclosure relate to a modular mobile platform capable of navigating through different downhole environments, including environments with branch and diversion channels flanking the main borehole, and using such modular Systems and methods for mobile platforms.

[0028] Such as Figure 1-9 As shown, mobile platform 10 includes a plurality of interconnected modules 12-32 for traveling through downhole environments having different geometries. Modules 12-32 each have a respective housing that is generally sized such that the overall shape of mobile platform 10 is suitable for movement through a borehole. More specifically, the mobile platform 10 defines a generally cylindrical robot, as shown, wherein the discrete housings of the various modules may each be cylindrical and elongated along the longitudinal axis of the mobile platform 10 . The modules 12 - 32 make up the mobile platform 10 when interconnec...

Abstract

A modular mobility platform has extendable and retractable tractor treads for engaging the walls of a downhole environment. The extendable and retractable tractor treads allow the platform to successfully navigate longitudinally through the downhole environment. The platform is composed of a plurality of different modules removably interconnected together longitudinally. Each module has at least one specific function, such as sensing, navigation, mobility, control, communication, power, or a combination thereof. The platform has longitudinally-directed detectors for detecting the forward or reverse direction through which the platform is to travel. A front end of the platform having a sensor at the forward end thereof articulates to navigate the mobility platform laterally through splits in the downhole environment. A system and method use the modular mobility platform.

Description

technical field [0001] The present disclosure relates generally to geological drilling and downhole processes, and more particularly to modular mobile platforms configured to travel through and navigate different downhole environments, and to systems and methods for using such modular mobile platforms. Background technique [0002] During processes in geological environments, such as downhole in wells or pipelines, it is advantageous to use robots or mobile platforms with electronics-based instrumentation to probe the environment and inspect the borehole walls. However, the downhole environment where the robot travels longitudinally presents challenges to known robots because the lateral width within such an environment can vary widely. As a result, the sides of the robot may scrape or bump into walls, potentially damaging the robot and its instruments. [0003] Many robots in the prior art also have a fixed structure, such as a housing to hold a fixed set of motors for tra...
