Seismic reservoir characterization is a well-known technique to obtain a better understanding of hydrocarbon-bearing reservoirs by careful analysis and integration of petrophysical and seismic data. The petrophysical properties are normally obtained through the evaluation of well logs and core data. A rock physics model provides the link between these reservoir properties and the surface seismi...

Foam injection is widely applied in amounts of fields to drilling, production, and formation protection. Sometimes, the application result is disappointing, which is caused by the failure of bubble generation in foam flooding. Therefore, it is necessary to seek ways for improving the performance of foam injection. An increased disturbance to the stratum, like the vibration caused by a seismic o...

Treatment of age-macular degeneration requires monthly intravitreal injections, which are costly and have serious risks. The objective of this study was to develop a novel intraocular implant for drug delivery. The capsule drug ring is a reservoir inserted in the lens capsule during cataract surgery, refillable and capable of delivering multiple drugs. Avastin was the drug of interest in this s...

Vapor-dominated geothermal systems, including The Geysers and Larderello, have experienced significant increases in noncondensible gas during their productive histories. A depletion model has been developed to explain these increases. In the model, the low permeability of the reservoir rock matrix initially retards the flow of vapor through the matrix to fractures due to the plugging effect of ...

The Bouillante geothermal field presently provides about 8% of the annual electricity needs of the French West Indies island of Guadeloupe. It has been the subject of a large number of studies covering various disciplines. These results enable the proposal of a hydrogeological conceptual model of the field. The reservoir consists of two perpendicular sets of fractures and faults, related to maj...

The Oligo-miocene Asmari formation is one of the most important hydrocarbon reservoirs in the southwest of Iran. In order to evaluate reservoir quality and the factors controlling reservoir properties, detailed geological and petrophysical studies were carried out on 242 m of core samples from Asmari reservoir. This study is a part of a larger project that examines depositional history and rese...

this study concerns the scope to improve water flooding in heterogeneous reservoirs. we used an existing, in-house developed, optimization program consisting of a reservoir simulator in combination with an adjoint-based optimal control algorithm. in particular we aimed to examine the scope for optimization in a two-dimensional horizontal reservoir containing a single high permeable streak, as a...

During nearly 25 years of water injection development in Gaotaizi reservoir LHP oilfield, due to poor physical properties, adaptability well pattern and difficulty establishing effective displacement between oil Wells, linear injection, infill adjustment refracturing tests have been carried out successively. Although certain effects seen, the are short unsatisfactory. In this paper, microscopic...

Polymer has been successfully used to enhance crude oil recovery at high water cut stage. However, the application of polymer flooding is limited by heterogeneity reservoir. In this work, role in heterogeneous reservoir was explored nuclear magnetic resonance (NMR) spectroscopy. Parallel core displacement experiments were carried out study formation. The results showed that area related permeab...

A possibility of using bottom sediments from dam reservoirs in earth structures was considered. Sediments the Rzeszow reservoir (Poland) were used as research material, which, according to geotechnical standards, classified low permeable silt with high organic content. As fine, cohesive soil a coefficient permeability, can be sealing elements hydraulic engineering embankments. In order verify s...
