Abstract

Sand production represents a serious problem during hydrocarbon production from sandstone reservoirs. Sand production lowers production rates, damages production equipment, and thus has a potential to deteriorate the value of a producing well. Since sand control is generally an expensive investment for an oil/gas operator, it is beneficial to conduct analyses capable of predicting the onset of sand production. In this study, a high-resolution 30 finite element model of the wellbore - perforation system is constructed and utilized for a staged finite element analysis to simulate the state of stress after drilling and perforating. Based on elasto-plastic material properties and considering different Andersonian stress regimes, plastic strain and principle stresses are computed and graphically presented to show the locations prone to failure and thus sand-production.

Biography

Kaixiao was a student from China University of Petroleum (Beijing). He transferred to Missouri S& T during 2011 Fall Semester. He works as an undergraduate research assistant and helps Mr. Amin Amirlatifi, a PhD candidate, with his C02 sequestration project by running several reservoir simulation models. Kaixiao is currently a student teaching assistant for PE 338, Finite Element Analysis Applied in Petroleum Engineering. He is also the PetroBowl Chair for Society of Petroleum Engineers Missouri S& T Chapter.
