Sandstone formations are ubiquitous in both aquifers and petroleum reservoirs, of which clay is a major constituent. The release of clay particles from pore surfaces as a result of reduced injection fluid salinity can greatly modify the recovery of hydrocarbons from subsurface formations by shifting the wettability properties of the rock. In this paper we demonstrate a microfluidic approach whe...


 The article describes Reza gold deposit of Ugur exploration area located in Geda- bek Ore District the Lesser Caucasus NW Azerbaijan. It is established that main mineralization consists hematite-barite-quartz-kaoline veins- veinlets and breccia, pyrite stock-stockverk quartz-sulfide veins. On orebody surface center secondary quartzites with vein-veinlets barite-hematite have occured over...

Cultivating sandy soil is a promising solution to overcome the fight against hunger especially in the developing countries. The main problems of sandy soil are moisture holding capacity and nutrients deficiency. A containers experiment was carried out to study the enhancement of water productivity and crop yield of sandy soils treated with clay. The container size was 31 x 15 x 60 cm with one t...

Extended Abstract Phosphorus is a major factor in the eutrophication process, and sensitive areas prone to contamination from domestic sewage must meet stringent effluent limits [6]. The Ontario Ministry of Environment standards, outlined in the Lake Simcoe – Phosphorus Reduction Strategy, must be consulted to comply with the current baseline limit of 0.30 mgP/L [9]. The objective of this study...
