Since pressure while drilling (PWD) has the disadvantages of single-point measurement and high cost of application, a micro-measurer based on MEMS (micro-electromechanical systems) sensor technology, which can measure downhole temperature, pressure, magnetic field, and dynamic signal, has been developed to achieve real-time, efficient, and accurate measurement of multiple parameters in the well. The kernel circuit system is the core of measurement and control, and the shell plays the role in protecting the kernel circuit. The shell of the micro-measurer is made of preferably selected materials with high-temperature and high-pressure resistance, corrosion resistance, small size, and low density, which can adapt to working in drilling fluid for a long time. The micro-measurer uses integrated interfaces on the shell to enable communication between the host computer and measuring machine. Based on the field test, both the functional integrity and data measurement accuracy of the micro-measurer are verified. Through analysis of the measured data, the profile of the downhole temperature field is constructed. The physical phenomena reflected by the measured magnetic field signal and dynamic signal are consistent with the actual working conditions observed in the test. Hence, as a new microchip measuring device, the micro-measurer can better serve the drilling engineering field and provide technical support for real-time measurement of downhole parameters in the future.

In a highly sensitivity oil and gas upstream conditions, there is a need for a real-time interaction platform to cope with harsh environment. The oil and gas business faces data validity constraints in terms of reliability, accuracy, and repeatability to name a few. The Internet of Sensors (IoS), with appropriate utilization, will play a major role in the industry's digital transformation. Predetermined IoS platforms with applicable characteristics are functioning in critical oil and gas environment applications. For example, some oil and gas wells produces harmful gases, like hydrogen sulfide (H2S). Fiber-optic sensors can be used as a leak detection tool for H2S resistance to inform oil and gas curfew if harmful gas is detected at the well site using cloud computing. Scale and corrosion monitoring of external pipelines is one of the integrity challenges. Ultrasonic sensors are embedding for real-time scale thickness feedback and corrosion monitoring by utilizing wireless transmission directly to end-user devices. A paradigm shift is happening with the IoS applications in oil and gas operations for sensitivity, reliability, and accuracy that will add intelligence, smart decisions, and control to the operational landscape. A comprehensive review of the art in oil and gas IoS presented in this paper. The target is to evaluate state-of-the-art IoS platforms for hazardous environments such as oil and gas facilities in terms of type of sensors used, applicability, functionalities, linearity, and accuracy, type of output signals, outputs range, and materials used. This work establishes classification and comparison of the IoS for better data collection, communication, connectivity, observation, and reporting in the world of oil and gas sensors. The IoS platforms classified and compared in tables consisting of different characteristics for the best-suited IoS platform designs in oil and gas appliance applications. This will provide references for IoS design engineers.

Dissolvable Materials for Buoyancy Driven Downhole Robots

Dissolvable materials made a positive impact in many downhole applications by reducing down-time, cost, and operation complexity, especially as frac plugs. For a new application for these materials, here we investigate their deployment as ballasts that can be attached to buoyancy driven untethered downhole robots, such as the Sensor Ball [1]-[2]. The Sensor Ball is an untethered downhole tool that takes a ballast to sink in the well fluids and releases it to become buoyant, hence it can return to the surface. Although the ballast is released on-demand via a magnetic actuator, using a dissolvable ballast is useful for two reasons: 1) The clutter left behind is minimized; 2) Provides a fail-safe mechanism such that the buoyancy is regained even when the weight releasing system fails. The Sensor Ball needs a ballast material that is as dense as possible to easily offset its effective density. Among the readily available materials, aluminum alloys are suitable, but pose problems such as highly exothermic reaction. These materials can cause extreme heating that can raise the local temperatures over 100 °C at downhole pressures. A secondary issue is the byproduct formation and aggregation. The aggregated solids inside water cause a mud-like viscosity that can entrap the Sensor Ball. Polymer spray coatings and separation of functions for clutter prevention and fail-safe mechanisms were effective in reducing the exothermic heating and mud formation. We also investigated 3D printed dissolvable polymer containers with metal powders. Although this method was useful in addressing the heat generation problem, the containers showed mechanical integrity problems.
