A new formulation for lightweight oil well cement slurry using a natural pozzolan [PDF]
, 2019 Fluid loss during cementing operation in depleted reservoirs or in deep wells of reservoirs with low breakdown pressure is a major concern for maintaining well integrity. To overcome this problem, the weight of cement slurry is usually reduced. Although
