Abstract
Systems, computer readable, and methods concern receiving seismic data representing a subsurface volume. The method also includes determining, for the seismic data, analysis coordinates as a function of time. One or more of the analysis coordinates may vary in position over time. The method includes performing at least one of an interpolation or regularization process on the seismic data based at least partially on the analysis coordinates. The method also includes outputting a result of the at least one of the interpolation or regularization process.
Claims17
A method for processing seismic data, comprising:
- receiving seismic data representing a subsurface volume;
- determining, for the seismic data, analysis coordinates as a function of time, wherein one or more of the analysis coordinates vary in position over time, wherein the one of more analysis coordinates includes a conversion point;
- performing at least one of an interpolation or regularization process on the seismic data based at least partially on the analysis coordinates;
- outputting a result of the at least one of the interpolation or regularization process;
- and
- performing a drilling action based at least partially on the result of the at least one of the interpolation or regularization process, wherein the drilling action comprises at least one of:
- varying a trajectory of a downhole tool to vary a trajectory of a wellbore, varying a weight-on-bit of a downhole tool, varying a flow rate of fluid being pumped into the wellbore, or varying a type of the fluid being pumped into the wellbore.
A computing system, comprising:
- one or more processors;
- and
- a memory system comprising one or more non-transitory media storing instructions that, when executed by at least one of the one or more processors, cause the computing system to perform operations, the operations comprising:
- receiving seismic data representing a subsurface volume;
- determining, for the seismic data, analysis coordinates as a function of time, wherein one or more of the analysis coordinates vary in position over time, wherein the one of more analysis coordinates includes a conversion point;
- performing at least one of an interpolation or regularization process on the seismic data based at least partially on the analysis coordinates;
- outputting a result of the at least one of the interpolation or regularization process;
- and
- performing a drilling action based at least partially on the result of the at least one of the interpolation or regularization process, wherein the drilling action comprises at least one of:
- varying a trajectory of a downhole tool to vary a trajectory of a wellbore, varying a weight-on-bit of a downhole tool, varying a flow rate of fluid being pumped into the wellbore, or varying a type of the fluid being pumped into the wellbore.
A non-transitory medium storing instructions that, when executed by at least one processor of a computing system, cause the computing system to perform operations, the operations comprising:

- performing at least one of an interpolation or regularization process on the seismic data based at least partially on the analysis coordinates;
- outputting a result of the at least one of the interpolation or regularization process;
- and
- performing a drilling action based at least partially on the result of the at least one of the interpolation or regularization process, wherein the drilling action comprises at least one of:
