Chpater 11 – Specialized Downhole Drilling Equipment
Air and Gas Drilling Field Guide, 2020Co-Authors: William C. Lyons, Reuben L. Graham, Greg D. HawleyAbstract:Publisher Summary There are two downhole Drilling devices used with air and Gas Drilling technology: down-the-hole hammer (DTH) and the progressive cavity positive displacement motor (PDM) Drilling motor. The DTH can only be used with an air or other Gas Drilling Operation with unstable Drilling fluids. The PDM was originally developed for use with incompressible Drilling fluids, but operates on unstable foam, aerated, and stable foam Drilling fluids. PDMs are nearly always used to drill directional boreholes. There are two basic designs for the DTH. One design utilizes a flow path of the compressed air through a control rod down the center hammer piston and then through the hammer bit. The other design utilizes a flow path in the wall of the hammer housing. This type of hammer design allows for the flow of Gas in this small annulus passage and then through the hammer bit. The most commercially successful positive displacement fluid downhole motor has been the progressive displacement “cavity” motor. The driving shaft of these motors is a rigid shaft composed of helical lobe repeating sections and is denoted as the rotor. Downhole pneumatic turbine motors are the only specialized downhole Drilling equipment that can be used with dry compressed air (or other Drilling Gases).

Air, Gas, and Unstable Foam Drilling
Air and Gas Drilling Field Guide, 2009Co-Authors: William C. Lyons, Reuben L. Graham, Greg D. HawleyAbstract:This chapter outlines the steps used to plan a successful deep air and Gas Drilling Operation and illustrates the application of these steps and methods to the planning of a typical deep Drilling Operation. Deep Drilling Operations with air and Gas Drilling technology are used in the recovery of oil and natural Gas and in the recovery of geothermal steam and hot water. The application of air and Gas Drilling technology is usually limited to either performance Drilling Operations in competent rock formations or under-balanced Drilling Operations in low-pressure reservoirs. The advantage of air and Gas Drilling Operations is that the bottom hole annulus pressures can be designed to be below the reservoir bottom hole pressure. Air and Gas Drilling Operations are different from traditional mud Drilling Operations and require more intensive attention on the part of the on-site Drilling Operation supervisor. Deep air and Gas Drilling Operations use a variety of compressed Gases as the Drilling fluid. The majority of the Operations use compressed air or membrane-generated nitrogen. Unlike the aerated and stable foam Drilling fluids, the modeling of air Drilling fluids is not a rheology issue. The major issues with air Drilling fluids are downhole combustion and the ability of the air Drilling fluid to carry formation water from the well.

Intelligent Judgment of Risks While Gas Drilling
Proceedings of the International Field Exploration and Development Conference 2018, 2019Co-Authors: Haitao Li, Lin Jiang, Hanming XuAbstract:At present, the basic monitoring method has been established on the site for the risk monitoring in the Gas Drilling process, but it is still not perfect. It is necessary for the monitors to analyze and judge the risk quickly and accurately when the monitoring data such as injection Gas pressure, Drilling time and sand discharge line pressure is abnormal, and the professional knowledge and field experience are extremely required for monitors. Therefore, it is urgent to establish intelligent judgment method for Gas Drilling risk, so as to ensure the safe and efficient Operation of Gas Drilling. This paper establishes the response relationship between the Gas Drilling monitoring parameters and the risk category. Based on the judgment theory of fuzzy hierarchy analysis, the monitoring parameters are classified and stratified. The global weight of nine risk monitoring parameters of the formation Gas, wellbore instability, formation water production, downhole bums, drill stem fracture, H2S production, stuck freeing, bit balling and drill piercement are analyzed, and the comprehensive judgment weight matrix is constructed. By analyzing the monitoring data and combining with expert experience, the reasonable fluctuation range of monitoring parameters is put forward, and the change vector of monitoring parameters is constructed, and the intelligent judgment method of Gas Drilling with Drilling risk is formed. This method can realize intelligent judgment, alarm, and other functions quickly and accurately, which monitor and judge in real time whether there is a downhole risk in the Gas Drilling Operation, so as to ensure the safety of construction.

Research on Data Analysis Model of Risk Assessment in Oil and Gas Drilling
Proceedings of the 21st International Conference on Industrial Engineering and Engineering Management 2014, 2015Co-Authors: Jiadi Li, Tingke Li, Wei Li, Lin JiangAbstract:Through the establishment of multidimensional data model based on data warehouse, we can convert the original application-oriented data structures in the database for the analysis of multidimensional data structures. Multidimensional data model provide a good data analysis environment for risk assessment system in oil and Gas Drilling and overcome inadequate analytical capacity which can’t satisfy complex analysis of risk assessment in oil and Gas Drilling Operation compared with information system based on database technology. Because the model provides a good analysis of structures, risk assessment of oil and Gas Drilling Operations can be analyzed from different perspectives and at different levels of the system related issues which provide an effective analytical tools and decision support for managers.
