Paper Number: SPE-166142-PA
Published: 11 November 2013
...George E. King; Daniel E. King Summary Do oil and gas wells leak to the environment? This paper will show the great majority of wells do not pollute. The purpose of this paper is to explain basic concepts of well construction and illustrate differences between single-barrier failure in multiple...

... on the outside, although this added burst strength is rarely considered in the typical conservative design ( Zinkham, 1962 ). Redundant, sequential design elements control failure-producing forces so a well can survive without loss of well integrity, even with the loss of one or more barriers in a multi-barrier...

..., fracture toughness and the compressive strength of the rocks. At present, Mohr-Coulomb criteria are used to characterize the failure of the rocks and it overestimates the tensile strength and has no limit on the maximum shear strength tolerance for the rocks. The new Vipulanandan failure model...

...: A threedimensional elastic/viscoplastic constitutive model for rock salt is proposed. This stress strain law takes into account the three phases of creep (transient, steady state and accelerated creep), dilatancy, as well as the failure and post failure behaviour. The model was implemented into a finite element...
