Surfactant abstraction by reservoir lIIinerals is goverlled by a nulllber of interacting pI,enomena owulg to the heteroqelltlity of the reservoir rock, the c~lex nature of the surfact.nts use.!, as well as the .ulticonponent nature of the reservoir fluid resulting fr~ the presence of inorqanics, co-surfactants, oil and polyJ:lers. The role of these factors in influencing die surfactant abstract...

We develop a case study planning process by using a strategy for balancing reservoir uncertainties (rock properties), optimum field development scenario (rate schedule and start time) and associated risks in the capital expenditures (price inflation and discount factor). The objective of this development is to recover dry gas reserves from five recently discovered fields in the most cost-effici...

Wildfires are an increasing threat in the Mediterranean region, causing frequent losses of goods and human lives. Not only wildfires a concern due to their immediate effects on vegetation soil, but they can also have substantial impacts surface water quality. Approximately one-third world’s largest cities obtain drinking from forest catchments. The removal consequent runoff increase with high c...

An integrated model is developed, based on seasonal inputs of reservoir inflow and rainfall in the irrigated area, to determine the optimal reservoir release policies and irrigation allocations to multiple crops. The model is conceptually made up of two modules. Module 1 is an intraseasonal allocation model to maximize the sum of relative yields of all crops, for a given state of the system, us...

OBJECTIVES Although antiretroviral therapy (ART) effectively suppresses HIV-1 replication, it does not eradicate the virus and ART interruption consistently results in rebound of viraemia, demonstrating the persistence of a long-lived viral reservoir. Several approaches aimed at reducing virus persistence are being developed, and accurate measurements of the latent reservoir (LR) are necessary ...

An important mechanism for postoperative cognitive impairment after cardiac surgery using cardiopulmonary bypass (CPB) is microemboli. One component of the CPB circuit-the cardiotomy-is a major source of gaseous microemboli because it aspirates significant volumes of air with blood from the operative field and intracardiac chambers. Cardiotomies are either integrated within an open hardshell ve...

The investigation and exploration of potential deep geothermal systems is based on detailed knowledge of their distinct reservoir characteristics. This is especially important in the exploration of potentially engineered geothermal systems and of mid to low enthalpy reservoir formations in greater depths, resp. In the early stages of geothermal reservoir exploration, characterization of the res...

An attempt was made to identify the productivity level of different zones of Nanak Sagar reservoir through the application of Geographical Information System (GIS). Based on biological, hydrological and soil parameters, thematic layers were created by interpolating point wise annual average value of given parameters and three models were developed using the weighted overlay method in ArcGIS v.1...

Geostatistical modeling of petrophysical properties is a key step in modern integrated oil and gas reservoir studies. Recently, generative adversarial networks (GAN) have been shown to be a successful method for generating unconditional simulations of poreand reservoir-scale models. This contribution leverages the differentiable nature of neural networks to extend GANs to the conditional simula...
