Oil-well cementsare used foroil-wellgrouting, sometimes calledoil-well cementing. They consist of either portland or blendedcements, plus additives.Oil-well cementmust be slow-setting and able to withstand the high temperatures and pressures of these deep wells. The process plays a significant role inwell-drillingoperations.
Erle P. Halliburton received a 1921 patent for an improved method forcementing oil wells, helping to bring greater production and environmental safety to America’s oilfields. When he patented his “Method and Means forCementing Oil Wells,” the young inventor revolutionized howwells…

Well Cementingis a process in whichcementslurry is introduced to the annular space between the casing and the open hole below the casing string. Thecementcreates a good bond between the pipe and the formation. Generally,Well Cementingcan be broadly categorized into two categories: Primarycementingand RemedialCementing.

The most successful and economical approach to remedialcementingis to avoid it by thoroughly planning, designing, and executing all drilling, primarycementing, and completion operations. The need for remedialcementingto restore awell’s operation indicates that primary operational planning and execution were ineffective, resulting in costly repair operations.

The ultimate goal ofcementingis to providewellintegrity through zonal isolation—a durable hydraulic seal in the wellbore that allows selective fluid production from subsurface formations and prevents leaks into other formations or to the surface. As production companies pursue reserves in high-cost, high-risk environments,well cementingand sustained wellbore integrity are increasingly critical to the success …
