abstract: mineral scaling in oil and gas production equipment is one of the most important problem that occurs while water injection and it has been recognized to be a major operational problem. the incompatibility between injected and formation waters may result in inorganic scale precipitation in the equipment and reservoir and then reduction of oil production rate and water injection rate. ...
یکی از روش های مرسوم ازدیاد برداشت در مخازن نفتی جهان از جمله در مخازن نفتی ایران و سوریه روش سیلاب زنی آب است اما میزان نفت باقی مانده بعد از فرآیند سیلاب زنی آب بسیار بالا است اشباع بالای نفت باقی منانده ناشی از راندمان کم جاروبی و رخ دادن سریع پدیده مخروط شدگی می باشد. این مشکل توسط تزریق پلیمر رفع می شود. پلیمر دارای مزایایی مانند افزایش ویسکوزیته اب کاهش قابلیت تحرک آب و دستیابی به جبهه هم...
recently, a renewed interest arises in the application of nanotechnology for the upstream petroleum industry. in particular, adding nanoparticles to fluids may drastically benefit enhanced oil recovery and improve well drilling, by changing the properties of the fluid, rocks wettability alteration, advanced drag reduction, strengthening the sand consolidation, reducing the inter-facial tension and...

this study attempted to explore if teaching english collocations through two different modes of awareness-raising and input flooding has any possible differential effect on immediate retention as well as retention in a delayed assessment. it also compared the possible differential effect of teaching english collocations implicitly and explicitly on actively using the items in writing. m...
A successful cross-linked polymer flooding has been implemented in JD reservoir, an ordinary heavy oil reservoir with high permeability zones. For all that, there are still significant volumes of continuous oil remaining in place, which can not be easily extracted due to stronger vertical heterogeneity. Considering selective plugging feature, polymer enhanced foam (PEF) flooding was taken as fo...
Abstract: Enhanced foam flooding is a chemical flooding technology, which is applied to improve the recovery efficiency of oil and gas. The oil displacement agent of enhanced foam flooding is a foam that the polymer and surfactant solution as liquid. In this paper, three-dimensional mathematical model of unsteady flow is established about enhanced foam system in the porous media, and the numeri...
A parallel reservoir simulator has been developed, which is designed for large-scale black oil simulations. It handles three phases, including water, oil and gas, and three components, including water, oil and gas. This simulator can calculate traditional reservoir models and naturally fractured models. Various well operations are supported, such as water flooding, gas flooding and polymer floo...
