Multiple scale fracture conductivity test considering fracture type, proppant placement mode, proppant size and concentration, etc. In shale gas fracturing...

... Abstract Guar and its derivatives, hydroxyl propyl Guar (HPG), carboxy methyl propyl Guar (CMPG), are currently the major gelling agents used for fracturing. However, there is the problem of insoluble residues in Guar after gel breaks. Such residues cause formation damage and low conductivity...

... Abstract Optimization of conductive fracture area is perhaps the most critical tenets of fracture stimulation. Several attempts have been implemented to improve the effective fracture area, such as hybrid fracturing, ultra-lightweight proppant (ULWP) delivery, channel fracturing, and slug...

... The success of sustained conductive acid fracture depends on the reaction of the HCl and calcite, resulting surface etching pattern, reaction to horizontal stress, and how the rock formation behaves elastically ( Abass et al., 2006 ). Through acid fracturing shale formations, the carbonate...
