Abstract: A method for performing a fracturing operation in a subterranean formation of a field. The method includes obtaining, during the fracturing operation, distributed optical fiber data from a downhole sensor of a treatment well in the subterranean formation, and determining, based on the distributed optical fiber data, an active perforation location from a number of pre-determined perforation locations of the treatment well. The active perforation location is a location of fluid flow into the subterranean formation during the fracturing operation. The method further includes generating, based at least on the active perforation location, a fracturing model for the subterranean formation, and performing, based on the fracturing model, modeling of the fracturing operation to generate a modeling result.

Abstract: The present disclosure relates to a method comprising: receiving a resource model associated with a resource site and receiving one or more objective parameters, such that a first objective parameter comprised in the one or more objective parameters is a function of one or more parameter values of the resource model. The method comprises executing simulations to generate a first uncertainty value based on at least one of a first parameter value and a first uncertainty value of a first parameter of the resource model. The simulations may be executed to generate a first forecast uncertainty value for each scenario comprised in a plurality of scenarios. The method also identifies one service that minimizes an uncertainty value of the objective parameter based on the forecast uncertainty value. The method further includes generating a first visualization comprising the one identified service for viewing by a user via a user interface.

Abstract: The present disclosure relates to a system that is operable to receive an execution plan and execute a control operation on one or more equipment based operations within the execution plan. The one or more operations may include a data capturing operation associated with a resource site. In one embodiment, the system may be operable to execute at least a first operation in response to a success variable of the data capturing operation indicating a successful execution of the data capturing operation. The first operation may include a quality control operation that is executed by comparing at least one characteristic of the captured data to an expected characteristic to generate quality state data. The quality state data may have one of an acceptable status and an undesirable status. In response to the quality state data indicating an acceptable status for the quality control operation, executing at least a second operation.

Abstract: A system and method for performing a fracture operation on a well site having a subterranean formation with a reservoir therein. The method involves measuring at least one seismic wave before and after stimulating the subterranean formation, comparing the seismic waves measured before the stimulation of the subterranean formation to the seismic waves measured after stimulation of the subterranean formation, and determining at least one fracture parameter of the subterranean formation from the compared seismic waves.

Abstract: Methods and systems are described for measuring effects of a hydraulic fracturing process. The techniques can utilizes cross-well seismic technology, such as used in Schlumberger's DeepLook-CS tools and service, or in some case surface to borehole or borehole to surface seismic technology. The downhole seismic sources at known locations can be conventional sources or can be other types of equipment operating at known locations such as perforation guns. The source is activated or swept creating energy which is transmitted through the formation. The energy is recorded at the receiver array and processed to yield a tomographic image indicating changes in the subterranean formation resulting from the hydraulic fracturing process. The process can be performed pre and post hydraulic fracture stimulation to generate a difference image of propped fractures in the reservoir.

Abstract: A method and system model of the formation and rock matrices in a well site. A microseismic event from a hydraulic fracture in a well bore is recorded at a monitoring well site. The S-coda wave window of the microseismic event is identified. Q-factors for a set of frequencies within the S-coda wave window are then identified.
