Patent number: 8214188Abstract: A method and apparatus associated with the production of hydrocarbons is disclosed. The method, which relates to modeling and operation of drilling equipment, includes constructing one or more surrogates for at least a portion of a bottom hole assembly (BHA) and calculating performance results from each of the one or more surrogates. The calculated results of the modeling may include one or more vibration performance indices that characterize the BHA vibration performance of the surrogates for operating parameters and boundary conditions, which may be substantially the same as conditions to be used, being used, or previously used in drilling operations. The selected BHA surrogate may then be utilized in a well construction operation and thus associated with the production of hydrocarbons.Type: GrantFiled: September 30, 2009Date of Patent: July 3, 2012Assignee: ExxonMobil Upstream Research CompanyInventors: Jeffrey R.
