a tait like equation for estimating the density of nontraditional super lightweight Completion Fluid at high pressure and temperature
Petroleum Science and Technology, 2013Co-Authors: Munawar Khalil, Badrul Mohamed Jan, Abdul Aziz Abdul RamanAbstract:Novel nontraditional super lightweight Completion Fluid (SLWCF) has been proven to be the best means to ensure the success of underbalance perforation. Field test showed that the application of this new Fluid has improved the well productivity. The authors present density measurements of SLWCF at high pressure and temperature. Density values of the Fluid were measured in laboratory at high temperature ranging from 313.15 to 393.15 K, and pressure up to 25 MPa. Measured densities were fitted to a Tait-like equation. Calculated absolute average deviation, the maximum deviation, bias, and standard deviation values show that the developed model can be used to express the Fluid density over a wide range of pressure and temperature. In addition, density value predicted by a Tait-like equation shows a good agreement both with laboratory and field data.

rheological and statistical evaluation of nontraditional lightweight Completion Fluid and its dependence on temperature
Journal of Petroleum Science and Engineering, 2011Co-Authors: Munawar Khalil, Badrul Mohamed Jan, Abdul Aziz Abdul RamanAbstract:Abstract This study presents a concise rheological and statistical evaluation of a novel super lightweight Completion Fluid (SLWCF) and the effect of temperature on its viscosity. Eight rheological models were proposed in order to describe the viscoplastic behavior of the Fluid. Based on the results, the Fluid is best described both by the Sisko model and the Mizahri–Berk model. These two models are not only able to quantify the relationship between shear rate and shear stress accurately, but also accommodate the physical characteristics of the Fluids. On the study of Fluid's viscosity dependence on temperature, the result shows that the activation energy decreases with the increases of shear, and its pattern follows a power equation. It could be concluded that viscosity is more sensitive to temperature changes at low shear rate. On the other hand at high shear rate, viscosity seems to be less dependent on temperature.

Fractional factorial design optimization of nontraditional Completion Fluid for perforation with underbalance
Chemistry and Technology of Fuels and Oils, 2010Co-Authors: Munawar Khalil, Badrul Mohamed Jan, Abdul Aziz Abdul RamanAbstract:Optimal well performance is always associated with the creation of a clean and undamaged connection between wellbore and reservoir. However, it is apparent that the use of shaped-charge perforating tends to produce perforation-induced formation damage. This damage impairs Fluid flow and decreases well productivity. To minimize and eliminate this damage, underbalance perforating should be considered. Underbalance perforating has been considered as one of the best means of providing a transient surge flow for tunnel cleanup. This paper introduces the formulation of super lightweight Completion to achieve underbalance condition. The formulation was optimized using fractional factorial design. The result indicates that the experimental data and model predictions agreed well. The optimum formulation condition is able to produce a stable Fluid with minimum and acceptable density and viscosity.

Application of Natural Clay to Formulate Nontraditional Completion Fluid that Triples Oil Productivity
World Academy of Science Engineering and Technology International Journal of Chemical Molecular Nuclear Materials and Metallurgical Engineering, 2010Co-Authors: Munawar Khalil, Badrul Mohamed Jan, Abdul Aziz Abdul RamanAbstract:In the last decades, the problem of perforation damage has been considered as the major factor for the reduction of oil productivity. Underbalance perforation is considered as one of the best means to minimize or overcome this problem. By maintaining wellbore pressure lower than formation pressure, perforation damage could be minimize or eliminated. This can be achieved by the use of nontraditional lightweight Completion Fluid. This paper presents the effect of natural clay in formulating nontraditional Completion Fluid to ensure successful perforation job and increase of production rate. Natural clay is used as homogenizing agent to create a stable and non-damaging low-density Completion Fluid. Results indicate that the addition of natural clay dramatically increase the stability of the final Fluids. In addition, field test has shown that the application of nontraditional Completion Fluid increases oil production by three folds. Keywords—Completion Fluid, underbalance, clay, oil production.

Flow properties of super light weight Completion Fluid for perforation cleanup during underbalance condition
All Days, 2010Co-Authors: Munawar Khalil, Badrul Mohamed Jan, Abdul Aziz Abdul RamanAbstract:Abstract In cased holes wells, perforation tunnels are the only passage for Fluid flow from reservoir to the wellbore. By establishing a clean connection during perforation job, optimum well productivity could be achieved. However, perforation-induced formation damage is always observed along and around the perforation tunnel as the result of perforation. One of the best alternatives to avoid this damage is with the application of underbalanced perforation. During the last decades, such techniques have been developed to achieve underbalance condition prior to gun detonation. As an alternative to these techniques, novel Completion Fluid referred as super light weight Completion Fluid is formulated. The use of super light Completion Fluid shows that underbalance condition could be achieved easily without additional works, major cost, and special surface equipment. In other words, no new procedures and equipment are needed to handle the super light weight Completion Fluids. Field test based on the basic laboratory formulation showed that the application of the super light weight Completion Fluid in underbalanced perforation has markedly increased the hydrocarbon production. This paper presents the investigation of flow properties and its effect to the temperature of super light weight Completion Fluid. The experimental data were fitted to six different rheological models, namely Newtonian, Bingham, Casson, Ostwald-De-Weale, Herschel-Bulkley, and Mizhari-Berk. The results indicated that Fluid rheological data is best represented by Mizhari-Berk model. On the other hand, the dependency of the Fluid on temperature could be described by Arrhenius model since the calculated R-square was relatively high. The calculated activation energy value of the super light weight Completion Fluid is 3.5533 kcal·mol−1; indicating that the temperature is not significantly affecting the Fluid properties.

rheological behavior and temperature dependency study of saraline based super lightweight Completion Fluid
Journal of Petroleum Science and Engineering, 2015Co-Authors: Zulhelmi Amir, Munawar Khalil, Badrul Mohamed Jan, Ahmad Khairi Abdul Wahab, Zulkafli HassanAbstract:Abstract This article presents a rheological and statistical evaluation of Saraline-based super lightweight Completion Fluid (SLWCF) and its effect on operating temperature. In this work, eight rheological models, namely the Bingham plastic, Ostwald–de Waele, Herschel–Bulkley, Casson, Sisko, Robertson–Stiff, Heinz–Casson, and Mizrahi–Berk, were used to describe the rheological behavior of the Fluid, and the results were compared with Sarapar-based SLWCF. The results showed that the Fluid was best described by both the Sisko and the Mizrahi–Berk models. These two models seem to be able not only to describe the relationship between shear rate and shear stress accurately but also able to accommodate the physical characteristics of the Fluids. In the study of Fluid viscosity dependency on temperature, the experimental data showed that the viscosity of Sarapar-based SLWCF almost doubled the viscosity of Saraline-based SLWCF. Furthermore, the activation energy seemed to decrease dramatically for both Fluids at low shear and tended to remain constant at a higher shear rate. However, Saraline-based SLWCF seemed to be less dependent on temperature, and its behavior could be described by the power equation. Results also showed that the viscosity of the Saraline-based SLWCF was more sensitive to temperature changes at low shear rates.
