Changes were made to drilling equipment and practices to be able to drill to 5000 metre radius wells from anoffshore production platform. Based on an optimised long reach well design, drilling equipment was sized and selected to achieve good drilling parameters and then integrated into a seven year old drilling rig. Drilling practices were modified to take advantage of the changes and a training programme assisted the smooth resumption of drilling.

The final cost of the upgrade project was US $9.5 million.
