Abstract
A method may include obtaining a request to determine automatically a depth of a formation top for a well in a geological region of interest. The method may include obtaining various well logs regarding the well and various wells in the geological region of interest. The method may include determining various depth values using the various well logs and a statistical interpolation method. The method may further include determining a final depth of the well using the various depth values and a searching method.
Claims20
A method, comprising:
- obtaining, by a computer processor, a request to determine automatically a depth of a formation top for a well in a geological region of interest;
- obtaining, by the computer processor, at least one well log regarding the well and a plurality of well logs regarding a plurality of wells, wherein the plurality of well logs are acquired in the geological region of interest;
- determining, by the computer processor, a plurality of depth values using the plurality of well logs and a statistical interpolation method, wherein the plurality of depth values describe locations of formation tops interpolated between a plurality of acquired formation top depths;
- and
- determining, by the computer processor, a final depth value of the well using the plurality of depth values and a searching method.
A system, comprising:
- a logging system coupled to a plurality of logging tools and a well in a geological region of interest;
- a reservoir simulator comprising a computer processor, wherein the reservoir simulator is coupled to the logging system and comprises functionality for:
- obtaining a request to determine automatically a depth of a formation top for the well;
- obtaining, using the logging system, at least one well log regarding the well;
- obtaining a plurality of well logs regarding a plurality of wells, wherein the plurality of well logs are acquired in the geological region of interest;
- determining a plurality of depth values using the plurality of well logs and a statistical interpolation method, wherein the plurality of depth values describe locations of formation tops interpolated between a plurality of acquired formation top depths;
- and
- determining a final depth value of the well using the plurality of depth values and a searching method.
A non-transitory computer readable medium storing instructions executable by a computer processor, the instructions comprising functionality for:
- obtaining a request to determine automatically a depth of a formation top for a well in a geological region of interest;
- obtaining at least one well log regarding the well and a plurality of well logs regarding a plurality of wells, wherein the plurality of well logs are acquired in the geological region of interest;
- determining a plurality of depth values using the plurality of well logs and a statistical interpolation method, wherein the plurality of depth values describe locations of formation tops interpolated between a plurality of acquired formation top depths;
- and
- determining a final depth value of the well using the plurality of depth values and a searching method
