Abstract

Process for interpreting one or more borehole images for use in drilling operations. In some embodiments, the process can include providing an input borehole image obtained from a downhole measurement provided by one or more downhole sensors. The process can also include collecting contextual information relative to the borehole image and the user. The process can also include using the collected contextual information and a mathematical model to infer one or more processing arguments. The mathematical model can be defined by using previously collected arguments and previously collected contextual information. The process can also include processing the input borehole image with the one or more inferred processing arguments to generate one or more interpreted borehole images. The process can also include adjusting one or more drilling operation based, at least in part, on the one or more interpreted borehole images.

First claim

What is claimed is:

1. A process, comprising:
collecting a plurality of user-defined arguments relative to a plurality of borehole images, wherein at least one of the plurality of user-defined arguments corresponds to a type of geological formation or a feature of interest in a geological formation;
training a machine-learning model based on the plurality of user-defined arguments, wherein the machine-learning model is configured to infer one or more additional user-defined arguments corresponding to the type of geological formation, the feature of interest in the geological formation, or both with respect to one or more additional borehole images;
receiving an input borehole image obtained from a downhole measurement tool comprising one or more downhole sensors located within a borehole formed in a formation;
collecting contextual information relative to the input borehole image;
using the collected contextual information and the machine-learning model to infer one or more processing arguments, wherein the machine-learning model is defined by using previously collected arguments and previously collected contextual information;
analyzing, via the machine-learning model, the input borehole image with the one or more inferred processing arguments to generate an interpreted borehole image comprising a recognized type of geological formation, a recognized feature of interest in the geological formation, or both; and
adjusting one or more drilling operations based on the recognized type of geological formation, the recognized feature of interest in the geological formation, or both, wherein adjusting the one or more drilling operations comprises modifying geosteering of the drilling operations to follow a desired path based on the interpreted borehole image.

2. The process of claim 1 , wherein the plurality of user-defined arguments further corresponds to a location of the borehole, an orientation of the borehole, one or more dips, a user profile, or a combination thereof.

3. The process of claim 1 , wherein the plurality of user-defined arguments is obtained from a user.

4. The process of claim 1 , wherein analyzing the input borehole image comprises performing a workflow comprising at least a first processing operation and a second processing operation, wherein an output of the first processing operation is used as an input of the second processing operation.

5. The process of claim 1 , wherein the interpreted borehole image is obtained from the input borehole image without any user intervention.

6. The process of claim 1 , wherein the one or more downhole sensors include an acoustic sensor, a radiation sensor, a seismic sensor, an electromagnetic sensor, or a combination thereof.

7. The process of claim 1 , wherein the one or more downhole sensors are lowered into the borehole with the downhole measurement tool comprising a logging while drilling tool, a wireline tool, or a slickline tool.

8. The process of claim 1 , further comprising determining one or more dips surrounding the borehole from the interpreted borehole image.

9. The process of claim 8 , wherein the one or more dips surrounding the borehole are used to identify the recognized feature of interest in the geological formation.

10. The process of claim 1 , wherein the input borehole image is displayed on a display.

11. The process of claim 10 , wherein at least a portion of the plurality of user-defined arguments is provided by a user after viewing the input borehole image on the display.

12. The process of claim 1 , wherein the one or more drilling operations include complete and incomplete boreholes.

13. The process of claim 1 , wherein modifying geosteering of the drilling operations to follow the desired path comprises adjusting the desired path to maintain the borehole within a topmost geological layer of the formation.

14. The process of claim 1 , wherein modifying geosteering of the drilling operations to follow the desired path comprises adjusting the desired path to cause the borehole to intersect a naturally occurring fracture within the formation.

15. The process of claim 1 , wherein modifying geosteering of the drilling operations to follow the desired path comprises slowing down drilling, reducing a mud pressure, increasing a quantity of cement introduced into the borehole, and/or installing tubing within the borehole to prevent collapse.
