Title: 3D characterization of acidized fracture surfaces
Author: Malagon Nieto, Camilo
Abstract: The complex interrelations among the different physical processes involved in acid fracturing make it difficult to design , and later , to predict the outcome of stimulation jobs . Actual tendencies require the use of computational models to deal with the dynamic interaction of variables . This thesis presents a new study of acidized surface textures by means of a laser profilometer to improve our understanding of the remaining etched surface topography and its hydraulic response . Visualization plots generated by the profilometer identified hydrodynamic channels that could not be identified by the naked eye in acidized surfaces . The plots clarified the existence of rock heterogeneities and revealed how the processes of dissolution function in chalk rock . Experimental data showed clearly that the effect of dissolution depends on the type of rock and the fluid system ; dolomite , for example , dissolves more rapidly but more roughly than limestone . Fluid leakoff rate and temperature also affect the dissolution . Further research is necessary to clarify the effects of conductivity .
