Accuracy in Salt Dissolution Modeling
4Sal allows the modeling of various salt dissolution types, ensuring greater accuracy in the analysis of well structure impact.
SimWorx is heading the “4Sal” (Petrobras) development, a numerical simulator that deals with the drilling mud and salt layer contact, mostly related with the salt layer dissolution caused by the drilling mud contact.
Associated with the salt layer, which is also integrated in the model. As one may expect, if the drilling mud – salt layer contact happens in an uncontrolled fashion, the whole well structure can be compromised.
Salt layers are composed of a variety of different salts, therefore it is necessary to model the dissolution behavior of an array of different salts in contact with water and synthetic based drilling mud.
Dissolving the salt layer can cause an increase (undesired) in the wellbore diameter. The simulator addresses such scenarios regarding salt gravel transport and dissolution, as well as wellbore anomalies due to salt creep.
SimWorx is now the sole responsible for 4Sal development, including new mathematical models, numerical optimization and User Interface. The contract also covers the web application version of it. Key on assuming that project was the increase in our team of Chemical Engineers allowing a more effective contribution on the development of various dissolution models.

4Sal allows the modeling of various salt dissolution types, ensuring greater accuracy in the analysis of well structure impact.
The simulator prevents the undesired increase in wellbore diameter, a potential consequence of salt dissolution, helping to avoid structural failures.
The inclusion of the creep phenomenon in the model provides a comprehensive view of the interactions between drilling mud and the salt layer, essential for in-depth analysis.
The expansion of the chemical engineering team enabled more effective contributions to the development of dissolution models, fostering innovations in the project.
4Sal includes a web version that enhances flexibility and usability for engineers during the development and monitoring of operations.
