  • Publication number: 20200341167
    Abstract: Selecting a fracing-plan-to-apply to optimize a complexity index includes identifying a set of controllable input variables that defines a fracing plan. Initial values for the set of controllable input variables are defined. The initial values of the set of controllable input variables are processed to produce an initial stimulated geometry. A complexity estimator is applied to the initial stimulated geometry to produce an initial complexity index, which is evaluated to identify at least one variation from the initial values, which is processed to produce a variation stimulated geometry for each of the at least one variation from the initial values. The complexity estimator is applied to the at least one variation stimulated geometry to produce a variation complexity index for each of the at least one variation from the initial values. The fracing-plan-to-apply is selected from among the initial values and the at least one variation from the initial values.

  • Patent number: 10794175
    Abstract: Many monitoring systems, including distributed fiber optic sensing systems, are deployed to measure temperature, strain, acoustic, pressure, and electromagnetic data in a multi-well hydrocarbon field. By coupling disparate fiber optic cables together for strain sensing, a tubular cable is created that can be spooled and deployed as a single unit while allowing for multi-parameter sensing. Multiple tubular cables can measure and transmit sensing data from wellbores and geological formations. The data can be used to continually update a reservoir model and optimize production efficiency while also managing and mitigating subsidence by controlling injection and production rates.

  • Patent number: 10416328
    Abstract: Some aspects of what is described here relate to seismic profiling techniques. In some implementations, a time-sequence of seismic excitations are generated at seismic source locations in a first directional wellbore section in a subterranean region. Each seismic excitation is generated at a respective time and at a respective subset of the seismic source locations. A time-sequence of seismic responses are detected at one or more seismic sensor locations in a second directional wellbore section in the subterranean region. The time-sequence of seismic responses is associated with the time-sequence of seismic excitations. A fracture treatment of the subterranean region is analyzed based on the time-sequence of seismic responses.

  • Patent number: 10227847
    Abstract: A reservoir simulator system models the effect of proppant damage on reservoir production through calculation of a fracture closure stress versus fracture permeability relationship, which is mathematically transformed into a pore pressure versus fracture permeability relationship. Based upon the pore pressure relationship, the system models reservoir production while taking into account the permeability reduction in the fractures brought about due to proppant damage.
