In the early 1990s, Neotec (now SPT Group) was approached by several engineers working in UBD. They were aware of our reputation for modelling the production of gas-liquid mixtures and hoped that we would be able to adapt that expertise to a new application.

Since that time, we have continuously been involved in providing drilling engineers with an effective tool for modelling underbalanced and managed pressure drilling. As a result of this ongoing effort, our steady-state thermohydraulic model, WELLFLO , has become the industry standard for steady state UBD flow modelling.

We would like to thank you and all at Neotec for providing us with the copy of WELLFLO which has been of wonderful help to us in understanding the nuances of our project report.

The technical help provided by Neotec has been simply wonderful and has helped us immensely in the successful completion of our report. The three of us, Amith Nair, Rohit Patil, & Self would like to especially thank you for the personal interest that you have taken in our report.

As promised, on completion we would send a copy of our report on Underbalanced Coiled Tubing Drilling (UB-CTD), please find attached a copy for the same."
