Oil And Gas Drilling

Mud has prominent role in drilling operation, it enhances to protect the drilling well from blowout by obstructing the formation pressure and failure. It gives exact information about presence of formation gasses and fluids at every part of the drilled hole. It‘s very essential to maintain mud with different proportions to have proper and un-interrupted drilling process. Because estimating earth formation is of much difficulty and active mud should readily available at every instant. In order to have proper and un-interrupted drilling process and to maintain mud with different proportions mud activating devices viz., mud-agitator and mud gun are used in existing mud tanks. On observation it is found that nearly 33% of mud in the tank is not influenced with these activating devices. Due to which the flow of mud from the tanks to the drill string is not in exact composition and also there is accumulation of mud chemicals[17] at the bottom of the tank which causes several problems. This paper emphasizes the design of shaft-blade assembly which runs horizontally along the length of the tank in order to activate mud in that tank effectively. The shaft-blade assembly was designed and analyzed in the ANSYS and from the results it was found that the stresses in the shaft-blade materials are well within the limits for the proposed design. Economic aspects of the design are also discussed in this paper at the end.

Purpose Oil and gas industries play a major role for the growth of world economy, and drilling operation is considered as most important and hazardous procedure at the same time for oil and gas drilling crew because of the lack of effectual and user-friendly safety and health teaching and learning aids with updated knowledge and training capability. According to the previous studies, there is an urgent industrial need for user interactive technological aid for enhancing the teaching and learning of oil and gas drilling crew and safety officials at onshore and offshore drilling domains to fulfill the requirements of fourth industrial and educational revolutions. Therefore, this proposed virtual reality (VR)-based Hazard Free Operation (HAZFO Expert 2.0) teaching and learning aid to reduce the workplace risk and hazards to enhance the vestibule and experiential learning performance of oil and gas drilling process at Pakistani drilling industries. Design/methodology/approach In this proposed product based study for interactive teaching and learning application for industry, sequential explanatory research design will be adopted to prevent the accidents according to the modern technologies in this era of IR 4.0. Whereas, for the development of VR-based educational aid for Pakistani oil and gas industries, Autodesk 3ds Max, visual studio and MySQL software’s will be used. Findings This new concept of VR-based interactive educational aid (HAZFO Expert 2.0) for accident prevention at oil and gas drilling industries will be based on potential hazards and their suitable controlling measures for onshore and offshore drilling sites. Practical implications VR-based interactive educational aid for oil and gas workforce will facilitate the health and safety professionals for the elimination of potential hazards associated with oil and gas drilling activities to the next level of identification of hazards which has been identified in HAZFO Expert 1.0 at onshore and offshore drilling sites. Originality/value This proposed VR-based interactive educational aid for safe drilling process will be the first visual teaching and e-learning technology which covers all onshore and offshore drilling operations in Pakistani oil and gas industries and provides effective hazard controlling strategies to overcome challenging industrial hazards.

This article discusses the conceptual action plan and detailed methodology for the identification of potential hazard controls and the development of work integrated E-vestibule training module for safe onshore and offshore oil and gas drilling operation at Malaysian industries. According to the previous studies, there is a sheer industrial need of an effective work integrated vestibule training module for accident prevention at oil and gas drilling sites at Malaysian drilling domains. In this proposed study, 80 drilling crew will be randomly selected for quantitative research phase. Similarly, 03 safety experts will be purposively selected for qualitative research from each drilling domain. Whereas, for the identification of hazard controlling measures What-If analysis and thematic analysis approaches will be adopted. Furthermore, the open source vestibule training module will be developed by using ADDIE based on identified hazard controlling measures. However, the visual studio and MySQL software will use to develop the E-Module for drilling crew safety training. The proposed E-vestibule training module development framework will be used as an effective source for the elimination of life-threatening drilling hazards associated with its activities at oil and gas industries. Similarly, the proposed framework can also be implemented on other work-based learning training designs. Moreover, this proposed safety and health vestibule training module will be the first E- drilling safety module which covers all onshore and offshore drilling operation in Malaysian oil and gas extraction settings.

Drilling Operation

<p>Horizontal drilling technique is one of the methodologies that have been widely implemented recently to improve the production of oil and gas wells. Several directional drilling technologies can be utilized to drill the horizontal wells, vary from the simple mud motor technology to Bottom Hole Assembly (BHA) with the advanced motorized rotary steerable system. The most common challenges that are faced on horizontal drilling process are on the torque and the stick-slip throughout drilling process, which can be a technical limiter for the length of horizontal section that would be achieved. Stick-slip is the vibration <br />that occurs due to cyclical rotation acceleration and deceleration of the bit, BHA or drill string. This speed fluctuation can be zero to rate of penetration (ROP) or far in excess of twice the rotational speed measured at the surface. Stick-slip can significantly decrease the ROP, increases tool failures and damage, affects borehole quality, and impacts the data acquisition. Several studies had been done on the stick-slip prevention and mitigation throughout creation of new technology and drilling parameters envelope throughout drilling operation, however no study has ever been done on the modification of the design and <br />arrangement of the BHA itself to produce more stable BHA. Drill pipe is the longest component of the drill string and hence it has biggest contribution towards the drill string dynamic. This study will focus on the analysis of the combination of several designs of the drill-pipe and heavy weight drill-pipe (HWDP) that has different stiffness and characteristic to produce less <br />vibration, more efficient drilling operation and to create zero impact on the data acquisition measured while drilling. FEA drilling dynamic simulator was used to optimize the drill sting configuration. The calculation is made from the depth of 750 m to 2801 m. Based on the drilling simulation results of FEA modeling, it is concluded that the minimum stiffness ratio to give stability of the drill string of Well-Z7 BHA and Well-Z6 BHA is 0.012175272 and 0.07366999, respectively.</p>
