Materials for Well Integrity – Mechanical Properties and Hydraulic Sealability
By Mohammadreza Kamali, Adijat Ogienagbon (UiS)
ABSTRACT
In this presentation, fluid-state properties, mechanical properties and the hydraulic sealability of four alternative stetting material for cementing operation are included. The materials tested are: industrial class of expansive cement, a pozzolanic material, geopolymer, and thermosetting resin. The test results of each material are compared together to find the corresponding current strengths, sealability and shortcomings linked to each mix design. All the tests are performed at equal conditions. The condition for testing materials is bottom-hole circulation temperature and bottom-hole static temperature are 65 and 90 ◦C, respectively and pressure is 170 bars.
Presenters are Ph.D candidates at UiS :
Mohammadreza (Reza) Kamali is PhD candidate at the Department of Energy and Petroleum Engineering, University of Stavanger. In his project, Reza works with alternative setting materials for well cementing operation. In three years of being active in cement laboratory, he examined fluid-state and long-term mechanical properties of candidate barrier materials.
Adijat Ogienagbon, is a 2nd year PhD candidate at the Department of Energy and Petroleum Engineering, University of Stavanger. She currently works on a project titled “Fluid migration modelling and treatment”, where she studies the causes of well leakages, the leakage flow paths and test viable treatment methods.
