| The present invention relates to a multi-typed radial collector well cross water intake system and, more specifically, to a multi-typed radial collector well cross water intake system which comprises multiple vertical wells which are inserted and disposed underground at a fixed depth and along the riverside at constant intervals and which collect underground water contained in an aquifer; multiple first horizontal wells connected to the upper parts of the vertical wells and provided with screens filtering the underground water contained in the upper side of the aquifer; multiple horizontal second wells connected to the lower parts of the vertical wells and provided with screens filtering the underground water contained in the lower side of the aquifer; and a water intake pump provided on the vertical well. The multi-typed radial collector well cross water intake system according to the present invention includes a radial water collector well functioning as a water collector well which collects water from the lower aquifer, and a radial water collector well functioning as a water recharging well which has the effect of improving the water collecting performance even when the water collecting amount of the aquifer is short since the underground water is supplied from the upper aquifer by connecting the upper aquifer and the lower aquifer, and is provided to reduce maintenance costs by reducing the occurrence of the screen blocking phenomenon of the horizontal well, which is caused by the long-term water collection, by alternately running the water collector well and the water recharging well, to collect the underground water whose quality is improved by being collected after flowing from the water recharging water and passing through the lower aquifer, and to increase the amount of collected water by collecting the underground water contained in both of the upper and lower aquifers. | ||||||

| Disclosed is a well configuration and method of forming the configuration and producing hydrocarbons from the configuration. In one embodiment, multiple fractures are formed from a wellbore in a subterranean hydrocarbon gas formation. One fracture is filled with material to create a flow barrier that modifies the flow pattern of at least one fluid within the subterranean hydrocarbon formation. Also disclosed is the process of injecting a Dew Point altering gas into the formation on one side of the barrier and producing a mixture of formation gas and injected gas from the fractures on the other side of the barrier. | ||||||

| The method begins drilling a borehole from the surface to an underground shale matrix. A pipe is inserted into the borehole. Openings are created in the pipe in fluid communication with fractures in the shale matrix. The interior surface of at least one section of pipe is coated with a contaminant-capturing substance. Fracturing fluid including water, proppants and various chemicals is pumped through the pipe and into the fractures in the shale matrix. The fluid re-enters the pipe from the shale matrix and moves toward the surface through the coated pipe section where contaminants are sequestered by the coating. Natural gas or oil from the fractured shale then enters the pipe and moves to the surface to be collected. The coated pipe section remains in the ground permanently such that the necessity of disposing of the captured contaminants is eliminated. Alternatively, the contaminant-capturing substance can be coated onto the proppants which remain lodged in the fractures in the shale matrix. The method can also be used in situations not involving gas or oil recovery, such as removing contaminants from the cooling system of a nuclear reactor. | ||||||

| A flow conduit may have at least one orifice, which conduit is in the vicinity of a flow source. The source is at least partially covered (and flow blocked by) an optional temporary coating or barrier (e.g. filter cake). The flow pathway between the orifice and the source is temporarily blocked with a degradable material. A delayed degradation material layer is present over or covering the degradable material. The delayed degradation material layer degrades at a rate slower than the degradable barrier. The degradable material and delayed degradation material layer disintegrate (e.g. via time, temperature, a solvent). The degradable material optionally produces a product that removes the temporary coating. The method is useful in one context of recovering hydrocarbons where the flow conduit is the casing or liner of the well and the flow source is a subterranean reservoir where the coating is filter cake. | ||||||
