In exploratory and development wells, risks increase when different than expected well conditions are encountered during drilling. This case study provides an example...

... standardized the new connection for the production casing and liner of these wells. From the moment this connection was implemented, 82 strings (production casing and liner) have been run in both 9-5/8" and 7" sizes, successfully reaching all the target depths without any problems. drillstring design...
