Questions for Petrobowl

1. Having directionally dependent properties. - Anisotropic 2. A multiphase flow regime in which the lighter fluid flows in the center of the pipe, and the heavier fluid is contained in a thin film on the pipe wall. - Annular flow 3. Fluid pressure in the annulus between tubing and casing or between two strings of casing. - Annular pressure 4. Production of formation fluid through the casing-tubing annulus. - Annular production 5. The maximum flow rate a well could theoretically deliver with zero pressure at the middle of the perforations. - Absolute open flow (AOF) 6. Fluid flow in the borehole from one zone into another in response to pressure differences between the zones. - Back flow 7. The pressure within a system caused by fluid friction or an induced resistance to flow through the system. - Back pressure 8. Another term for reverse circulation, the intentional pumping of wellbore fluids down the annulus and back up through the drillpipe. - Backwash 9. A flow regime resulting from combined simultaneous linear flow in perpendicular directions. - Bi-linear flow 10. A well shut in slightly above the producing formation by use of special downhole tools containing a valve that can be preprogrammed or controlled from the surface. - Bottom hole shut-in
