“…The purpose of MPD solutions is to maintain the downhole pressure within the geopressure limits, but for technical reasons they are in fact controlling the downhole pressure at a particular depth in the well. There are several techniques available to achieve this goal: annular backpressure MPD (Bjørkevold et al 2010;Godhavn 2010), low-annulus-level MPD (Fossli and Hendriks 2008), dual-gradient MPD (Breyholtz et al 2011), and so forth. However, the controllability of the downhole pressure at a particular depth in the well is dependent on the compressibility of the drilling fluid with respect to the length of the drillstring and wellbore, the relative velocity of the mud and drillstring compared with the wellbore, the actual downhole conditions (i.e., in-situ drilling-fluid properties, annulus restrictions, and enlargements caused by cuttings or hole collapse), and the reaction time of the control technique itself.…”

Current topside and downhole instrumentation at the wellsite has been developed to manually conduct drilling operations. The emergence of automatic drilling-analysis software shows the limitations of today's measurement capabilities. It is therefore time to analyze the requirements for on-site instrumentation to implement new, efficient drilling-automation technologies.On one hand, drilling is facing more and more difficult conditions with narrow geopressure windows, deepwater, or high-pressure/high-temperature (HP/HT) conditions. On the other hand, unconventional hydrocarbon reserves may require a considerable amount of wells to be profitable. Drilling automation, by means of smart safeguards, automatic safety triggers, managed-pressure drilling (MPD), and ultimately complete or semiautonomous drilling rigs, can provide the solution to safely construct wells in these challenging settings.The common denominator for the vast majority of drilling-automation solutions is the use of physical models of the drilling process in the form of heat-transfer, mechanical, and hydraulic models. By analyzing the requirements of those models for necessary boundary conditions, it is possible to derive which measurements should be made both at surface and downhole to obtain stable and accurate calculations. This analysis also provides a way to estimate the necessary accuracy of the boundary conditions to ensure reaching the target control tolerance.By use of the boundary-condition analysis, it is possible to derive precisely which measurements should be performed and where they should be performed. As a result, a typical organization of sensors that is compatible with the implementation of drilling-automation solutions is derived.

“…The number of technological fields requiring in-situ and real time gas tracing is rapidly increasing and consequently the need for ad hoc sensing approaches for specific applications [1,2]. For example, the operating conditions for gas sensors employed in environmental monitoring [3] are very different with respect to sensors implemented in breath analysis systems [4,5] or integrated into pipelines for measuring natural gas composition from downhole [6,7]. In fact, one of the most important challenges in gas sensing is the development of versatile sensors and modules capable of detecting different noise, has been reached when a standard 32.7 kHz was employed.…”

In this paper the performances of two spectrophones for quartz-enhanced photoacoustic spectroscopy (QEPAS)-based ethane gas sensing were tested and compared. Each spectrophone contains a quartz tuning fork (QTF) acoustically coupled with a pair of micro-resonator tubes and having a fundamental mode resonance frequency of 32.7 kHz (standard QTF) and 12.4 kHz (custom QTF), respectively. The spectrophones were implemented into a QEPAS acoustic detection module (ADM) together with a preamplifier having a gain bandwidth optimized for the respective QTF resonance frequency. Each ADM was tested for ethane QEPAS sensing, employing a custom pigtailed laser diode emitting at ~1684 nm as the exciting light source. By flowing 1% ethane at atmospheric pressure, a signal-to-noise ratio of 453.2 was measured by implementing the 12.4 kHz QTF-based ADM, ~3.3 times greater than the value obtained using a standard QTF. The minimum ethane concentration detectable using a 100 ms lock-in integration time achieving the 12.4 kHz custom QTF was 22 ppm.

“…Advances in the field of oil drilling [1][2][3][4][5] and geothermal energy [6][7][8] extraction have made it possible to tap into previously uneconomic energy reserves that are hard to reach, such as crude oil reservoirs in deep sea locations or geothermal energy reserves stored at temperature around 300 °C and pressure above 200 MPa [9,10]. Finding and accessing these untouched reserves involve operating in increasingly harsh conditions, as well as ensuring the survivability of delicate electronic components in order to deliver high-quality measurements reliably.…”
