This article presents a new analytical procedure for pre-selecting gas wells water shut-off treatments based on available at hand results of an analysis integrated geological, reservoir and exploitation data. Attention was paid to assess the possibility appearance cross flows between layers in near wellbore zone. Their always eliminated well as candidate treatment. The basis assessing emergence...

Water is a major limiting factor in growth and reproduction in plants. The ability of tissues to survive desiccation is commonly found in seeds or pollen but rarely present in vegetative tissues. Resurrection plants are remarkable as they can tolerate almost complete water loss from their vegetative tissues such as leaves and roots. Metabolism is shut down as they dehydrate and the plants becom...

Oxidizing stimulation of organic-rich shale reservoirs, as a supplement hydraulic fracturing, was proposed to enhance gas recovery. Previous publications revealed that the interaction between and oxidative fluids causes components’ dissolution, which induces lots pores microfractures, resulting in rock microfracturing without confined pressure associated increments matrix permeability, improvin...

Introduction: The restoration of old fountains is essential to the cultural life society since it preserves architectural spirit past and conveys historical heritage present day. Besides, create a favorable atmosphere in summer, humidifying air. In course study, we developed an approach engineering systems technology operation fountain St. Petersburg.
