  • Development of a Novel Hybrid-Type Rotary Steerable System for Directional Drilling
    IEEE Access, 2017
    Co-Authors: Hyun Myung
    Abstract:

    Unlike conventional resources, unconventional resources, such as shale gas and coal bed methane, are situated horizontally under geological formations. To exploit these resources, Directional Drilling and hydraulic fracturing technologies are required. In Directional Drilling, the dog leg severity (DLS), which indicates how much the angle changes while Drilling 100 ft, is a major issue with respect to the cost and time of Drilling. In this paper, we briefly review different types of Directional Drilling methods and propose a new hybrid-type rotary steerable system (RSS). DLS calculations based on three-point geometry for these systems are suggested. This hybrid RSS combining two conventional types of RSSs: point-the-bit and push-the-bit systems, achieves better steerability. The hybrid mechanism is implemented using hybrid pads with hydraulic cylinders and a spherical joint. The advantages of the proposed system are demonstrated by performing small-scale prototype and cement block Drilling tests.

  • A novel steering sections of hybrid rotary steerable system for Directional Drilling
    2014 14th International Conference on Control Automation and Systems (ICCAS 2014), 2014
    Co-Authors: Byeolteo Park, Jae-uk Shin, Sungwook Jung, Hyun Myung
    Abstract:

    As the conventional resource drains, the importance of unconventional resource grows. A Directional Drilling system and a hydraulic fracturing method are required to gain unconventional resources. Nowadays, the key technology of the Directional Drilling is a rotary steerable system (RSS). Among several types of the RSS developed so far, `point-the-bit' and `push-the-bit' are the most commonly used ones. In this paper, we introduce several conventional Directional Drilling methods and propose a new hybrid-type rotary steerable system. This mechanism improves the steering angle by taking advantages of both `point-the-bit' and `push-the-bit' types. Its control should be synchronized all 360° for BHA(Bottom Hall Assembly) heading due to the hybrid mechanism.

  • Design and analysis of a new hybrid rotary steerable system for Directional Drilling
    IEEE ISR 2013, 2013
    Co-Authors: Jieun Park, Byeolteo Park, Hyun Myung
    Abstract:

    Recently, shale gas has become an important energy source. Directional Drilling is an imperative technology when it comes to excavating shale gas because it exists in underground in horizontally spaced areas. A rotary steerable system (RSS) enables the effective Directional Drilling. In general, there are two types of RSS, the point-the-bit and the push-the-bit. In this paper, a new hybrid type RSS is proposed. The hybrid type RSS has advantages of both the point-the-bit and the push-the-bit. We expect that the proposed RSS can increase the build-rate. The effectiveness of the proposed mechanism is discussed by predicting the side force.

  • Nonlinear modeling for analysis of Directional Drilling processes
    2020
    Co-Authors: Fahim Shakib, Emmanuel M Detournay, Nathan Van De Wouw
    Abstract:

    Directional Drilling allows for the Drilling of boreholes with complex shapes, which are needed to reach unconventional reservoirs of oil, gas and mineral resources. Figure 1 shows a sketch of a Directional Drilling system. The drillstring is a hollow slender pipe with most of it is in tension under its own weight, except for the bottom hole assembly (BHA), which is in compression. The BHA contains several stabilizers ensuring centering of the BHA inside the borehole, a bit penetrating the rock formation and a rotary steerable system (RSS), being a robotic actuator, steering the BHA. In practice, Directional Drilling often results in spiraled boreholes, see Figure 2 for an illustration. These are unwanted selfexcited oscillations in the borehole geometry which negatively influence the Drilling process and the borehole quality

  • Delay complementarity modeling for dynamic analysis of Directional Drilling
    2019 American Control Conference (ACC), 2019
    Co-Authors: M.f. Shakib, Emmanuel M Detournay, Nathan Van De Wouw
    Abstract:

    Hard-to-reach oil and gas reservoirs are nowadays accessed by Directional Drilling techniques, which use a rotary steerable system to drill complex curved boreholes. This paper aims at providing understanding of the complex behavior of Directional Drilling systems by developing a model for the borehole evolution and providing a dynamic analysis of the resulting model. The planar evolution of the borehole path is modeled in the form of a delay complementarity system, which accounts for undergauged stabilizers and a saturation of the bit orientation with respect to the borehole orientation. These are essential nonlinearities from a practical point of view. The pursued dynamic analysis reveals that these systems induce steady-state oscillations in the borehole path, which are related to the planar equivalent of the highly detrimental borehole spiraling observed in practice. The model and dynamic analysis provide essential insights and can serve in the further development of control techniques to track borehole paths while mitigating borehole spiraling.

  • Model-Based Robust Control of Directional Drilling Systems
    IEEE Transactions on Control Systems Technology, 2016
    Co-Authors: Niek Antonius Henricus Kremers, Emmanuel M Detournay, Nathan Van De Wouw
    Abstract:

    To enable access to unconventional reservoirs of oil and (shale-) gas, geothermal energy and minerals, complex curved boreholes need to be drilled in the earth's crust. Directional Drilling techniques, incorporating down-hole robotic actuation systems called rotary steerable systems, are used to generate these curved boreholes. In practice, however, boreholes drilled with such systems often show instability-induced borehole spiraling, which negatively affects the borehole quality and increases drag losses while Drilling. As a basis for controller synthesis, we present a Directional Drilling model in terms of delay differential equations. Next, the problem of curved well-bore generation is formulated as a tracking problem and a model-based robust control strategy is developed, solving this tracking problem while guaranteeing the prevention of borehole spiraling. The effectiveness of the proposed approach is illustrated by representative case studies for the generation of curved boreholes.
