Waterflooding adalah salah satu metode pemulihan sekunder yang bertujuan untuk mempertahakan tekanan reservoir. Volume air injeksi disesuaikan agar tidak terjadi penurunan oil recovery. Tujuan dari penelitian ini mengoptimalkan nilai Injection dan Recovery Factor (RF) dengan menggunakan Artificial Neural Network (ANN). Parameter digunakan porositas, permeabilitas horizontal, vertikal, saturasi ...

This work focuses on evaluating the effect of steam quality upgrading and recovering extra-heavy crude oil in presence absence two nanofluids. The nanofluids AlNi1 AlNi1Pd1 consist 500 mg·L?1 alumina doped with 1.0% mass fraction Ni (AlNi1) Pd (AlNi1Pd1), respectively, 1000 tween 80 surfactant. Displacement tests are done different stages, including (i) basic characterization, (ii) waterfloodin...

Generally, long-term waterflooding development often leads to the change of reservoir pore and clay mineral composition, which results in permeability wettability. In order explore relationship between core micropore structure water cut, based on physical simulation experiments fractal theory, we proposed a evolutionary model describe evolution characteristics microstructure driving reservoirs....

با توجه به رشد بالای جمعیت در جهان و نیاز اطمینان از امنیت غذایی، افزایش تولید واحد سطح محصولات زراعی به‌منزلة راهبردی اساسی حل مسئلة تأمین غذا به‌شمار می‌رود. سوی دیگر، وجود محدودیت زیرکشت پایین‌بودن میانگین عملکرد برخی کشاورزی مانند گندم کشور، محصول می‌تواند راهکاری عملی پاسخ کشور محسوب شود. یکی مهم‌ترین بیماری‌های فوزاریوم است که، نقش پیش‌بینی این بیماری جلوگیری کاهش بهره‌وری محصول، مدل‌هایی...

Introcution: Water-flooding is an effective way to develop the extra-low permeability oil reservoirs and water-flooding induced fracture (WIF) can improve waterflooding efficiency. However, geomechanical properties of rocks may alter due water-rock interactions, which usually increases heterogeneity reservoir affects WIF propagation. Methods: In this study, a method calculate propagation length...

Engineered water surfactant flooding (EWSF) is a novel EOR technique to reduce residual oil saturation; however, it becomes quite challenging obtain Winsor Type III microemulsion and the lowest IFT under actual reservoir conditions if only low salinity used. The main objective of this study was design negative gradient optimize performance hybrid method. Three corefloods were performed on carbo...
