[ 1 ] - A CFD Simulation of the Parameters Affecting the Performance of Downhole De-oiling Hydrocyclone
Among the all parameters affecting the performance of a downhole de-oiling hydrocyclone, the investigation of internal flow field deserves more attempts especially in the petroleum industry. In this study, the effects of inlet flow rate, inlet oil volume fraction, and oil droplet diameter on the separation efficiency and pressure drop ratio have been investigated along the hydrocyclone body. Al...
[ 2 ] - An Experimental Study of the Effect of Amines on Polymer Efficiency and Thermal Stability of Water-based Drilling Fluid
Amine compounds are believed to have acceptable results regarding their use as clay swelling inhibitor and corrosion inhibitor additives in drilling fluids. It is crucial to know the capability of amine compounds to enhance the thermal stability of drilling fluid; herein, a water-based fluid composed of biopolymer and other additives as the proper representatives of muds used in the pay zone se...
[ 3 ] - Thermal and Rheological Properties Improvement of Oil-based Drilling Fluids Using Multi-walled Carbon Nanotubes (MWCNT)
In this paper, we detail our results for the impact of MWCNT on the thermal and rheological properties of oil-based drilling muds. Our analysis considers the effects of time, temperature, and MWCNT volume fraction. The scanning electron microscopy imaging technique was used to monitor the MWCNTsdispersion quality. The experimental results unveil a considerable enhancement in the thermal conduct...
[ 4 ] - Pressure Profile Estimation through CFD in UBD Operation Considering with Influx to Wellbore
Nowadays, UnderBalanced Drilling (UBD) technology is widely applicable in the petroleum industry due to its advantages to an overbalanced drilling operation. UBD success depends on maintaining the drilling fluid circulating pressure below the reservoir pore pressure during operations. One of the main prerequisites of a successful UBD operation is the correct estimation of the pressure profi...
[ 5 ] - بررسی اثر سرعت تزریق اسید بر عملکرد فرایند اسید زنی در یک مدل دو بعدی ناهمگن
مدل سازی اسید زنی در مخازن کربناته یک ابزار مناسب برای تعیین رفتار دینامیک برای طراحی عملیات اسید زنی می باشد. یک فرایند اسید زنی مناسب باید موجب ایجاد کرم چاله های عمیق و نازک با کم ترین میزان اسید مصرفی شود. در این مقاله با استفاده از مدل پیوستگی دو مقیاسی و حل معادله ها به روش عددی تفاضل محدود، مدل سازی بهتری از فرایند اسید زنی و تشکیل کرم چاله ها به دست آمده است. در مدل‌سازی انج...
