Production of highly viscous tar sand bitumen using Steam Assisted Gravity Drainage (SAGD) with a pair of horizontal wells has advantages over conventional steam flooding. This paper explores the use of Artificial Neural Networks (ANNs) as an alternative to the traditional SAGD simulation approach. Feed forward, multi-layered neural network meta-models are trained through the Back-...

The Niger Delta is located in Southern Nigeria and is Africa’s largest delta, covering about 70,000 square kilometers, and with about one-third of it made up of wetlands, and the third largest world mangrove forests. The Niger Delta is unique in Nigeria because it is the home of Nigeria’s oil industry, with its attendant environmental hazards such as water, land, air pollution, etc. Human activ...

have to be considered. The first, which has been developed in the preceding section, is that passive smoking could act to disclose an asthmatic state that was so far asymptomatic. The second issue lies in the natural history of asthma. Following Martinez et al.’s publications, it has become obvious that transient wheezing could occur in non-atopic infants exposed to passive smoking. Because the...

The presented work discusses increasing oil recovery factor using physicochemical EOR methods.
 This article presents the field pilot tests results related to cyclical gel polymer flooding technology as applied under conditions productive reservoirs rich in high-viscosity oils (viscosity reservoir above 300 mPa s) of Buzachi North field, extending boundaries application these methods. used...
