POSC Specifications: Epicentre Version 3.0 | Logical Data Model |
A fluid which is displaced into a well to allow activities associated with the development of the well to continue. There are many functions which it can perform. Two important ones are the provision of sufficient hydrostatic head to manage sub-surface pressures and a solids carrying capacity to facilitate the removal of drilled cuttings or debris from the wellbore. In addition, they are usually designed to minimize the intrusion into downhole formations.
