Procedure for Setting Short Plugs
Where small amounts of cement are used, eg., when setting a plug across a window cut in casing, of maximum length 50 ft, the plug can be set by the “running plug” method as detailed below:
1. Run in with stinger to required depth. Ensure that the circulating head is only one metre above the drillfloor when the drillpipe is spaced out for pumping.
- Note: The stinger should have side jets and should be at least 100 ft longer than the planned cement plug. Use 3 . . .
