Additives are used to enhance cement slurries in all wellbore conditions. Variations in additive concentration may cause significant changes in thickening time, compressive strength, and viscosity, so determining the optimum balance of additives to achieve a reliable annular seal, particularly in extreme or corrosive down hole conditions, can be complex. Thus, field-proven technical solutions, laboratory-driven empirical data from analytical tests, and finite element analysis models play an important role when engineering an optimized slurry blend.
All of Halliburton's additive advancements were made with one goal in mind: to help operators benefit from a long-term tight annular seal and cement-sheath resilience for superior zonal isolation, even in technically demanding wells or environmentally sensitive areas.
