20160040518 | WELL TREATMENT FLUIDS - In-line electrolysis of well treatment fluid in a method and system to supply a treatment fluid downhole in the well. In the method, a treatment fluid is electrolyzed in a flow path to a downhole location to form one or more electrolysis products. In the system, an electrolysis cell has at least one electrode integrated in the flow path. Also disclosed is a method to treat a subterranean formation by modulating amperage to an electrolysis cell in the flow path to form a heterogeneous concentration of one or more electrolysis products to transform a self-agglomerating solid composition in the fracture into a channelized solids pack comprising clusters having a high concentration of solids, wherein the clusters are separated by open voids having a substantially reduced concentration of solids between the clusters. | 02-11-2016 |
20160053597 | HYDRAULIC FRACTURING WHILE DRILLING AND/OR TRIPPING - Methods and apparatuses for hydraulically fracturing a subterranean wellbore while drilling and/or tripping are disclosed. A method for hydraulically fracturing a subterranean formation may include rotating a drill string to drill the wellbore and hydraulically fracturing the subterranean formation at a plurality of axially spaced locations along the wellbore while tripping the drill string out of the wellbore. The drill string may include a hydraulic fracturing assembly. The hydraulic fracturing operation may include translating the drill string in an uphole direction so that a set of frac ports in the hydraulic fracturing assembly is adjacent a region of the formation selected for fracturing, expanding at least one pair of packers to seal an annular region of the wellbore exterior to the frac ports, and pumping fracturing fluid downhole through the frac ports to hydraulically fracture the subterranean formation. | 02-25-2016 |
