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.
