Abstract

This report presents an analysis on the effect of different angle of well inclination towards the buckling effects on the casing. The buckling effects are including the stress, shear stress, strain and minimum buckling force required for the casing to start buckle. It is essential to analyse the buckling effect on the inlined well as failure in tubing and casing will cause loss of wells, which give a negative impact economically. J. D. Clegg (1971) mentioned in his paper that combination of non- uniform load and hydrostatic external pressure is believed to have caused most of the casing and tubing failures. The interaction between angle of inclination and minimum buckling force required for the casing to start buckle is calculated theoritically, while the effect of different angle of inclination on stress distribution were simulated and observed using ANSYS 14. ANSYS software has proven to be a successful tool in studying and simulating the effect of different angle of inclination towards the stress distribution of on the casing surface. The result obtained from the simulations are succesful. As the angle of the well inclination increases, the stress exerted on casing surface was changed. Besides, increase in the angle of inclination also increased the shear stress on the casing surface. The distribution of the stress also changed as the angle is changed.
