  The Knowledge of the behaviour of cement slurries under elevated temperatures is necessary to understand properly cement rheology in moderate to deep-well cementing operations. The design of optimum cement slurry for oil well is highly challengeable for high temperature wells because slurry stability is a major requirement for successful oil well cementing the main objectives of cementing include, control abnormal pressure, zonal isolation, prevent from caving and wash out holes, support casing. For this purpose to understand rheological behaviour of cement slurry is essential for proper displacement and optimum placement at different temperature condition. Silica fume commonly available and cost-effective having sufficient quantity of amorphous substance to improvements in the physical and mechanical properties of cement slurry also a play very important role in strength development and increase rate of hydration. This paper describes to development of a cement slurry composition under laboratory condition to investigation the phenomena of optimum pump- ability through different concentration of silica fume from atmospheric condition to high thermal condition. Laboratory experiments showed that cement slurry is probably the more influenced by temperature; as temperature increased the changes occur in placing of cement slurry and the effect of high temperature decreasing plastic viscosity and yield point with the increasing temperature. The formulated cement slurry had advantages of low density, high strength, excellent rheology and high temperature tolerance, controlling the rheological behaviour of cement slurry can help to improve the relevant movement between particles, the stability and substitutability; according to the API standard.

  In Water Alternating Gas (WAG) injection processes, injected gas suffers from poor sweep efficiency due to low gas density, low gas viscosity leading to gravity segregation, override and viscous fingering. The oil recovery during the process remains low due to the problems of gravity segregation and viscous fingering. Foam surfactant is used to reduce gas mobility by increasing its apparent viscosity and improve volumetric sweep efficiency but the foam efficiency decreases in the presence of crude oil, divalent ions and high reservoir temperature. The main objective of this study is the screening of foam forming surfactants for CO2 mobility control during water alternating gas injection process in the presence of maximum divalent ions at high temperature. Alpha Olefin Sulfonate (AOS) was selected as main surfactant. Solubility test of AOS with different brine was performed at 120°C. AOS was stable in the total brine salinity of 78568 ppm with 3265 ppm of calcium ions and 1434 ppm of magnesium ions. To maximize the range of divalent ions, Lauramidopropylamide Oxide (LMDO) was blended with AOS. The solution was stable in the presence of total salinity 78358 ppm with 4082 ppm of calcium ions and 1793 ppm of magnesium ions at 120°C. The aqueous stability over a range of divalent ions and temperature was improved by blend of surfactants and this will help for generating stable foam for CO2 mobility control.
