Publication number: 20110214878Abstract: 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: ApplicationFiled: September 30, 2009Publication date: September 8, 2011Inventors: Jeffrey R.

Patent number: 6814141Abstract: This invention provides a method for improving oil recovery, preferably a high-viscosity oil relying on gravity drainage, by applying vibrational energy. A fracture is created at a wellbore and a fluid displacement device is inserted at or near the fracture opening. The optimum oil mobilization frequency and amplitude is determined. The fluid inside the fracture is oscillated to a prescribed range of frequency and amplitude to improve oil production. Applications for using the fracture as a delivery device for vibrational energy to enhance performance of the steam-assisted gravity drainage process, vapor-extraction gravity drainage, or cyclic steam process are provided. An application to improve recovery of heavy oil by aquifer drive or peripheral waterflood is also provided.Type: GrantFiled: May 9, 2002Date of Patent: November 9, 2004Assignee: ExxonMobil Upstream Research CompanyInventors: Chun Huh, Philip Lee Wylie, Jr., Jung-gi Jane Shyeh, Jeffrey R.
