A method and system for determining formation properties based on a fracture treatment that may include collecting data from a fracture treatment for a well. A flow regime of the fracture treatment is determined based on the data. Formation properties may be determined based on the flow regime and the data.

Method and system for determining formation properties based on fracture treatment

The present invention relates generally to methods for designing and optimizing the number, placement, and size of fractures in a subterranean formation and more particularly to methods that account for stress interference from other fractures when designing and optimizing the number, placement, and size of fractures in the subterranean formation. The present invention optimizes the number, placement and size of fractures in a subterranean formation. The present invention determines one or more geomechanical stresses induced by each fracture based on the dimensions and location of each fracture. The present invention determines a maximum number of fractures and a predicted stress field based on the geomechanical stresses induced by each of the fractures

Methods for geomechanical fracture modeling

The present invention is directed to a method of isolating hydrajet stimulated zones from subsequent well operations. The method includes the step of drilling a wellbore into the subterranean formation of interest. Next, the wellbore may or may not be cased depending upon a number of factors including the nature and structure of the subterranean formation. Next, the casing, if one is installed, and wellbore are perforated using a high pressure fluid being ejected from a hydrajetting tool. A first zone of the subterranean formation is then fractured and stimulated. Next, the first zone is temporarily plugged or partially sealed by installing an isolation fluid into the wellbore adjacent to the one or more fractures and/or in the openings thereof, so that subsequent zones can be fractured and additional well operations can be performed.

Methods of isolating hydrajet stimulated zones

The invention relates to methods and apparatus for creating multiple fractures in subterranean formations. The apparatus is a jetting tool having a plurality of sets of jetting nozzles so that the sets of nozzles are substantially parallel to one another such that parallel cavities may be formed substantially simultaneously in the formation. The jetting nozzles may be adapted to provide a fluid jet that flares outwardly from the nozzle. The nozzles also may be aligned such that cavities in the formation overlap to form a single cavity. The nozzles may be further adapted so that holes jetted into the casing thereby are still spaced from one another. Methods of fracturing subterranean formations using the apparatus are also disclosed.

Methods and apparatus for multiple fracturing of subterranean formations

A method of treating a subterranean formation or of stabilizing a surface within a subterranean fracture comprising: providing a treatment fluid comprising lightweight proppant at least partially coated with an adhesive substance; introducing the treatment fluid into a portion of a subterranean formation; depositing at least a portion of the lightweight proppant in the portion of the subterranean formation; allowing at least a portion of the lightweight proppant in the subterranean formation to form a particulate pack; and, allowing at least a portion of the adhesive substance to migrate from the lightweight particulates to a surface within the portion of the subterranean formation.

Methods of stabilizing surfaces of subterranean formations

Methods comprising providing a fracturing fluid comprising proppant particulates at least partially coated with a hardenable resin composition that comprises a hardenable resin component and a hardening agent component, wherein the hardenable resin component comprises a hardenable resin and wherein the hardening agent component comprises a hardening agent, a silane coupling agent, and a surfactant; introducing the fracturing fluid into at least one fracture within the subterranean formation; depositing at least a portion of the proppant particulates in the fracture; allowing at least a portion of the proppant particulates in the fracture to form a proppant pack; and, allowing at least a portion of the hardenable resin composition to migrate from the proppant particulates to a fracture face.

Methods and compositions for stabilizing the surface of a subterranean formation

Methods of initiating a fracture tip screenout, that comprise pumping an annulus fluid into an annulus, between the subterranean formation and a work string disposed within a wellbore penetrating the subterranean formation, at an annulus flow rate; and reducing the annulus flow rate below a fracture initiation flow point so that the fracture tip screenout is initiated in the one or more fractures in the subterranean formation, are provided. Also provided are methods of fracturing a portion of a subterranean formation and methods of estimating a fracture initiation flow point.

Methods of initiating a fracture tip screenout

According to one embodiment of the invention, a flow conditioning system for fluid jetting tools includes a housing having a plurality of jet nozzle openings and a fluid straightener disposed within the housing. The fluid straightener is defined by one or more vanes, and the vanes form a plurality of flow channels within the housing. Each flow channel is associated with at least one jet nozzle opening.
