Abstract
In drilling operations, the condition of the fluid downhole during circulation is very important because the alteration of the properties of the fluid could lead to a serious drilling and completion problem. Temperature is one of the key parameters to be considered during drilling operations, because it has the capacity to completely change the characteristics of the fluid system. Therefore, the choice of additives for the formulation of fluid systems is very important. The additives must be able to impact the desired properties to withstand the hole conditions expectations and meet up with the job expectation. In this study, three admixtures, namely; sodium silicate, gypsum and polyanionic cellulose R (PAC R) were selected. They were added to the cement slurries in two different concentrations (1.5% and 3.0% by weight of cement) with slurry weight of 12.5ppg. A neat sample was prepared to act as a control. The rheological properties, such as, plastic viscosity, yield point, shear stress-shear rate relationship and free fluid of the fluids were evaluated at 80℉, 120℉, 140℉ and 160℉. The rheological properties such as gel strengths at 10 sec and 10 min, plastic viscosity, yield point, shear stress-shear rate and free fluid determined. The results showed that all the fluids showed shear-thinning characteristics at the tested temperatures. The sodium silicate, gypsum and PAC-R showed good thermal stability and ability to suspend solid particles. The fluids stability increases with increase in concentration of the sodium silicate and gypsum. The PAC-R fluid was not mixable at 3%. The gypsum and the sodium silicate thin down with increase in temperature but still showed adequate suspension capability to be used as cement extender.
