MUD BASED CEMENTING MATERIAL CUTS DRILLING COSTS

Shell Development Co. has introduced a downhole cementing system that does not contain conventional Portland cement but instead consists of blast furnace slag and drilling mud. Shell said it can save operators thousands of dollars per well in drilling costs. Shell Offshore Inc. has used the drilling mud conversion technology in more than 70 wells and almost exclusively in its Auger field development project in Garden Banks Blocks 426 and 471 in the Gulf of Mexico.
