Utility
Reflection seismology internal multiple estimation
25 Jan 22
A method includes receiving seismic data of a seismic survey; defining a two-dimensional domain in dimensions x and y; identifying a target trace (S, R) of the seismic survey where S represents a source at (xs, ys) and where R represents a receiver at (XR, yR); defining with respect to the two-dimensional domain, a source trace (S, X1) as a primary trace, a receiver trace (R, X2) as a primary trace, and a generator trace (X1, X2) as associated with an interbed multiple generator; convolving the primary traces and crosscorrelating with the generator trace for a plurality of different (X1, X2) pairs where each of the plurality of (X1, X2) pairs defines a line segment where the line segments are substantially parallel to one another; and, based at least in part on the convolving the primary traces and crosscorrelating with the generator trace, generating seismic data with attenuated multiple energy.

Utility
Method for treating fractured subterranean formations with controlled solids setting in wellbore
11 Jan 22
Methods may include using geometrical and mechanical properties to generate a model of one or more intervals of a wellbore; designing a fluid pumping schedule for a wellbore treatment fluid system; simulating flow of a fluid system containing solids using the model of the one or more intervals of the wellbore, wherein simulating comprises determining the flow rate distribution within the wellbore and modeling the settling and resuspension of the solids within the flow of the fluid system; and updating the fluid pumping schedule based on the output determined from the simulated flow of the fluid system.

Utility
Method to predict reservoir formation permeability using combined acoustic and multi-frequency dielectric measurements
4 Jan 22
Methods may include calculating a formation permeability for a subterranean formation from a combination of dielectric measurements and acoustic measurements, wherein the formation permeability is calculated according to the formula: kg=a(Vxσw/εr)b, where Vx is either Vp, Vs, or Vp/Vs, σ is formation conductivity, Øw is water-filled porosity, and a and b are constants that are empirically determined for the frequency selected with respect to Vx; and creating a design for a wellbore operation from the calculated formation permeability.
