n: 1. forcing gas back into a formation by pumping into the annulus from the surface.2. any pumping procedure in which fluid is pumped into the well against pressure.

forcing fluids in the pipe into the formation at a pressure higher than the pore pressure and sometimes higher than the fracturing breakdown pressure. Used to displace a kick out of the pipe when wellbore and wellhead pressure limits permits.

n: the written reprot about all the wells made by the drilling team after completing drilling,nomally including heading,drilling data,drilling problems,indroduction to stopping drilling and advices

a summary of general well data, operation data, geologic data, etc., for a particular well after the final completion step.

n: intermittent flow of fluid from a well.

the information on the well at the top of the log.

the flow of slugs of fluids (unstable behavior).

pumping units used in bullheading, circulating or other operations involving liquid and foam pumping.

n: The ways of ordinary primary cementing,after tripping in casing ,firstly ,cleaning well by circulating drill fluid,secondly ,imputing spacer fluid and pressurizing lower plug, thirdly,imputing slurry and pressurizing up-plug,then bullheading quantitativ
