| 2 | A comprehensive investigation on the performance of durian rind as a lost circulation material in water based drilling mud显示文摘Oil and gas operators worldwide are expecting service companies to deliver integrated techniques to minimize,if not prevent,drilling problems.Drilling fluids perform vital functions to ensure the success of drilling operations.The technical challenges often associated with water-based drilling fluids are loss of critical properties,such as fluid loss control and rheology,under demanding conditions,such as in drilling deeper,high-temperature and high-pressure wells.Fluid loss during drilling operations has a very significant effect in both reservoir formation damage and monetary terms.The use of durian rind(DR)as a new additive in controlling lost circulation would provide another opportunity to reduce waste and avoid pollution.Therefore,DR was used to improve the rheological properties of water-based mud,and it was prepared for use as a fluid loss additive.For a better understanding of the influence of pectin on drilling mud properties,the rheological evaluation of untreated DR was compared to that of mud samples containing treated DR.The pectin in DR was extracted using four different solvents,namely,ethanol,methanol,sodium hydroxide and hydrogen peroxide,and the most effective solvent to remove the pectin was then determined.The Fourier transform infrared spectroscopy(FTIR)results showed that NaOH was the best solvent for removing pectin from DR.Thermogravimetric analysis(TGA)was used to determine the thermal stability of DR before and after treatments.The TGA results demonstrated that the treated DR had improved thermal stability compared to untreated DR.The sizes of DR used were coarse,medium,and fine.The untreated DR presented better rheological properties than the treated DR.The experimental investigation showed that a concentration of 20 lb/bbl of intermediate-sized DR was the best concentration among the tested samples. | Nor Fatin Fatihah Majid Allan Katende Issham Ismail Farad Sagala Norshila Md Sharif Mohd Azizi Che Yunuse | 2019 | Petroleum2019，5，3： | 0 |
| 3 | Mixture temperature prediction of waxy oil–water two-phase system flowing near wax appearance temperature显示文摘Temperature sensitivity of waxy crude oils makes it difficult to study their flow behaviour in the presence of water especially near their wax appearance temperature(WAT). In this study a method was proposed and implemented to mitigate such difficulties which was applied in predicting mixture temperatures(Tm) of a typical Malaysian waxy crude oil and water flow in a horizontal pipe. To this end, two analytical models were derived firstly from calorimetry equation which based on developed two correlations for defining crude oil heat capacity actualized from the existed specific heat capacities of crude oils. The models were then applied for a set of experiments to reach the defined three predetermined Tm(26 °C, 28 °C and 30 °C). The comparison between the predicted mixture temperatures(Tm,1and Tm,2) from the two models and the experimental results displayed acceptable absolute average errors(0.80%, 0.62%, 0.53% for model 1; 0.74%, 0.54%, 0.52% for model 2). Moreover,the average errors for both models are in the range of standard error limits(±0.75%) according to ASTM E230.Conclusively, the proposed model showed the ease of obtaining mixture temperatures close to WAT as predetermined with accuracy of ± 0.5 °C approximately for over 84% of the examined cases. The method is seen as a practical reference point to further study the flow behaviour of waxy crudes in oil–water two-phase flow system near sensitive temperatures. | Ali Piroozian Muhammad A.
