Abstract The post COVID-19 era will undoubtedly present paradigm shifts in operational planning and execution and advanced automation will become an important factor. However, drilling automation without directional drilling (Cayeux 2020) capability will exclude the use of automation in a vast number of fields where precise placement of the wellbore has shifted from a luxury to a necessity. This is important in unconventional plays where automation can make a step change in operational outcomes (Chmela 2020). However, most efforts in automating directional drilling are using bespoke rigs (Slagmulder 2016) and bespoke bottom hole assembly (BHA) that limit operational options. The goal is in designing systems that enable directional drilling automation (Chatar 2018) with existing BHAs. This paper will look at three challenges that were identified and overcome to deploy a vendor agnostic system for automating the directional drilling (DD) process. The three challenges identified here are as follows:Using any mud motor including low-cost motors in a closed loopIntegration with an existing measurement and logging while drilling (MLWD) systemAbility to roll out automation systems on any operations with existing rigs The system is a modification of an operator’s autonomous drilling system (Rassenfoss 2011), designed to use existing rigs, BHAs and have minimum footprint on the rigs for operational use. The system will have a dedicated connection to the rig’s programmable logic controller (PLC) via common industrial protocols including Modbus, EthernetIP or Profinet, a physical connection the MLWD receiver and a brain box with a cloud connection to aggregate, process data and send commands to the rig PLC to execute directional commands. A vendor agnostic system will increase adoption of automated technologies and further drive improvements in operational and business performance.

Typical Calculation

The article discusses the development of technology for directional drilling of oil and gas wells in the perspective of modeling downhole operations. The most significant mathematical models developed by Soviet and foreign scientists in the XX century are listed. An example of calculating the reaction on a bit based on the most widely used method of initial parameters is shown. In the process of a typical calculation of the deflecting force on the bit, it was possible to set the boundary conditions on the bottom hole assembly (BHA) supports in a natural form, using a well-known approach for calculating the deflection of the beam. The obtained results of calculations were applied in the construction of a simulation model for computer simulation based on a virtual program-simulator of the drilling directional wells. The simulating software allowed us to evaluate the effect of the Zenith angle of the well and the rigidity of the oriented layout on the deflecting force on the bit, the deflection of the turbo drill along the length from the bit to the nearest lower point of contact of the well wall.

The ATLAS experiment will undergo a full replacement of its inner detector to face the challenges posed by the High Luminosity upgrade of the Large Hadron Collider (HL-LHC). The new Inner Tracker (ITk) will have to deal with extreme particle fluences. Due to its superior radiation hardness the 3D silicon sensor technology has been chosen to instrument the innermost pixel layer of ITk, which is the most exposed to radiation damage. Three foundries (CNM, FBK, and SINTEF), have developed and fabricated novel 3D pixel sensors to meet the specifications of the new ITk pixel detector. These are produced in a single-side technology on either Silicon On Insulator (SOI) or Silicon on Silicon (Si-on-Si) bonded wafers by etching both n- and p-type columns from the same side. With respect to previous generations of 3D sensors they feature thinner active substrates and smaller pixel cells of 50 × 50 and 25 × 100 µm2. This paper reviews the main design and technological issues of these novel 3D sensors, and presents their characterization before and after exposure to large radiation doses close to the one expected for the innermost layer of ITk. The performance of pixel modules, where the sensors are interconnected to the recently developed RD53A chip prototype for HL-LHC, has been investigated in the laboratory and at beam tests. The results of these measurements demonstrate the excellent radiation hardness of this new generation of 3D pixel sensors that enabled the project to proceed with the pre-production for the ITk tracker.

Introduction. Directional drilling of wells is currently carried out by a rotary steerable system and conventional equipment including a mud motor with an adjustable skew angle. Either of the two methods has particular advantages. Research aim is to analyze the technologies provided by various service companies in the field of directional and horizontal wells drilling in order to provide means of improving the utilization capacity of the conventional bottom hole assembly in long horizontal boreholes. Methodology. When drilling directional wells with a small departure from the vertical and wells with horizontal boreholes up to 500 m long, a preference is given to a mud motor as far as a change in deviation parameters is concerned. This is due to the fact that the mud motor has a significant economic advantage. However, when drilling directional well with complex planned profile or a well with a horizontal borehole of more than 500 m, the mud motor may cause a variety of problems, while a rotary steerable system will allow to avoid some of them. Results. The rotary steerable system is not always economically feasible suggesting a need for an alternative technology with a more advantageous offer on the market of services. A system of pulsed controlled drilling will allow the adjustment of the trajectory of the wellbore when drilling in a rotary mode with conventional equipment for directional drilling, reduce rig time, and improve the borehole quality. Summary. The given technology will make it possible to improve the efficiency of conventional equipment which includes the mud motor for directional wells drilling with complex planned profile and long horizontal boreholes of more than 500 m, as soon as the technology provides the possibility of adjusting the trajectory in a rotary mode. The system of pulsed controlled drilling is developed as an alternative to the rotary steerable system making it possible to significantly reduce construction expenses for wells with complex geological conditions of drilling

Pressure, level, and flow transmitters are an integral part of a nuclear power plant’s primary cooling and steam generation system. To function accurately within the plant design specifications, normal operating and event instances of a Gen III or IV plant environment these transmitters will need to possess rugged and long life characteristics. These transmitters need to be high temperature, radiation, and high shock resistant. Lessons learned from legacy plants show the need to be able to both monitor and control cooling processes throughout the lifespan of the plant in addition to operating during and after a Loss of Coolant Accident (LOCA) occurrence. LOCA requirements associated with some new power plant designs stipulate extended performance after exposure to a 425°F (221°C) and 65 psig (4.5 bar) environment. An alternative and proven technology utilizes a bellows and control spring that reacts to the changes in pressure along with a radiation hardened and high temperature resistant Linear Variable Differential Transformer (LVDT) that converts the bellows travel into a VAC output signal. The LVDT VAC output is then converted into a 4 −20mA output using a signal conditioner containing high temperature and radiation hardened components. LOCA testing, performed on pressure and differential pressure transducers of various ranges, has shown that with proper material selection for the bellows, control spring, LVDT, and pressure boundary components, these sensors can successfully withstand environmental profiles of up to 600°F (315°C) at 250 psig (17 bar) for 30 minutes and 230°F (110°C) at 5 psig (0.34 bar), submerged, for 30 days. Application data has shown that these types of sensors possess long term stability and accuracy, require no periodic maintenance, and can have a forty year life. In addition, high impact shock testing per specification MIL-S-901 shows that the bellow/spring/LVDT sensor can withstand greater than 50g’s shock and still continue to function within specification.

This work systematically reviews the assistive technology solutions for pedestrians with visual impairment and reveals that most of the existing solutions address a specific part of the travel problem. Technology-centered approach with limited focus on the user needs is one of the major concerns in the design of most of the systems. State-of-the-art sensor technology and processing techniques are being used to capture details of the surrounding environment. The real challenge is in conveying this information in a simplified and understandable form especially when the alternate senses of hearing, touch, and smell have much lesser perception bandwidth than that of vision. A lot of systems are at prototyping stages and need to be evaluated and validated by the real users. Conveying the required information promptly through the preferred interface to ensure safety, orientation, and independent mobility is still an unresolved problem. Based on observations and detailed review of available literature, the authors proposed that holistic solutions need to be developed with the close involvement of users from the initial to the final validation stages. Analysis reveals that several factors need serious consideration in the design of such assistive technology solutions.
