Salt zone cementing; Cimentacao em zonas de sal

Abstract

This work introduces new concepts in the proposal of NaCl concentrations i cement slurry and operational parameters for cementing halite salt zones. Experiments carried out in the laboratory and in the Surface Hydraulic Simulator using real halite coring allowed the determination of halite dissolution rates in relation to flow, contact time, and initial Na Cl concentration in the cement slurries. An experimental procedure was developed to measure the adherence strength of hardened cement on halite formations. A Computer Simulator was developed with the adjustment of a model representing the physical phenomenon of mass transfer to the experimental results obtained, which enable us to calculate the Na Cl concentration profile on cement slurry after its positioning in the well's annular region, as well as the total mass of dissolved salt. Employment of the methodology developed in this work shall reduce risk of collapsed casing as well as the cost of the slurry. (author)
