Using Indian equal angle section, wind zone II and seismic zone III. And considering the plane terrain

Benefits of Using Continuous Circulation Systems in ERD Wells to Manage ECD, Bottom Hole Pressure and Hole Cleaning

Continuous Circulation Systems (CCS) have been around since the JIP between Shell, BP, Statoil, BG, Total and Eni in October 2000. Initial reports of these systems demonstrated that while cumbersome, the use of CCS is of benefit to drilling ERD wells. Continuous circulation keeps cuttings moving out of the wellbore, reducing or eliminating the time required to circulate clean any high-angle section before making a drill pipe connection or before tripping out of the hole. Continuous Circulation over each connection enhances the management of Equivalent Circulating Density(ECD) to control the bottom hole pressure on the well by never switching off the pumps, therefore the wellbore never experiences an Equivalent Static Density(ESD). Through this mechanism, the application of CCS has also been proven to manage bottom hole pressure constantly, which in conjunction with good drilling practices for torque and drag management, are key factors in drilling any Extended Reach Drilling(ERD), Complex or High Pressure/High Temperature (HPHT) well.

Numerical Investigation on Cold Formed Steel Angle Section Portal Frames

Cold formed steel portal frames are widely used as alternative to traditional portal frames made from hot rolled steel sections. Load-displacement response of cold formed steel single C-section portal frames is available. C- section portal frames undergo significant deformation before reaching their ultimate loads. In this study, cold formed steel angle portal frame is analyzed using finite element analysis in order to find the load-displacement response. Bolt pressure is applied at the location of physical bolts in ANSYS. Keywords- Cold formed steel portal frames, fasteners, bolts, connections, Numerical modelling

BEARING CAPACITY OF SINGLE-ANGLE COMPRESSION MEMBER: EXPERIMENTAL AND NUMERICAL INVESTIGATION

This study was conducted to investigate the load-bearing capacity of a single angle column under various loading conditions to determine the loading condition offering the highest load- bearing capacity. In all cases, the load is transferred through one leg (or two legs) of the angle which has a smaller cross-sectional area compared to the total area of the angle profile. The main objective of this study is to develop almost all of the possible support conditions for the single angle section and carry out laboratory tests on the chosen specimens to determine the most suitable one. Also, there are some finite element investigations done using ABAQUS software to find out the maximum forces in which all the elements of the structures remain their linear behavior and the stress spots concentration. Based on the obtained results, it is possible to increase the axial critical load of a single angle by using the connections at the main axis of the section.
