Abstract

Techniques for extracting well log data include cropping one or more portions of a page of a well log file image that includes solid color space; further cropping portions of the page that includes well log file data from the cropped page of the well log file image; executing an optical character recognition (OCR) technique on the cropped portions of the page that includes well log file data to generate an OCR'd image of the cropped portions of the page that includes well log file data; parsing the well log file data from the OCR'd image; and comparing the parsed well log file data against one or more well log file data-specific rules to determine user-specified well log file data from the parsed well log file data.

Claims (57)

1. A structured data processing system for extracting well log data, the system comprising:

one or more hardware processors;

further cropping a second portion of the cropped particular page that includes a second representation of the user-specified well log file data;

identifying a first area of the cropped particular page that encloses the first portion;

determining the first portion in the first area based on a delineated size or shape of the first portion;

identifying a second area of the cropped particular page that encloses the second portion; and

determining the second portion in the second area based on a delineated size or shape of the second portion;

executing an optical character recognition (OCR) technique on the cropped one or more portions of the particular page that comprises well log file data to generate an OCR'd image of the cropped one or more portions of the particular page that comprises well log file data, wherein the operation of executing the OCR technique comprises:

determining that a dots per inch (dpi) setting value of the cropped particular page meets a threshold setting value for the OCR technique;

determining that the cropped particular page comprises metadata that includes the dpi setting; and

executing the OCR technique on the first and second portions of the cropped particular page to generate an OCR'd image of the first and second portions that include the first and second representations of the user-specified well log file data;

parsing the well log file data from the OCR'd image;

comparing the parsed well log file data against one or more well log file data-specific rules to determine the user-specified well log file data from the parsed well log file data, wherein the operation of comparing the parsed well log file data comprises:

assigning a numerical point value based on the well log file data-specific rules to each of the one or more terms of interest;

scoring, according to the assigned numerical point value of each of the one or more terms of interest, each of a plurality of combinations of the one or more terms comprised of the first and second number of each of the one or more terms, each combination comprising a unique combination of values from the first and second sets of separate values of the one or more terms of interest;

sorting the scored plurality of combinations to determine a best score;

identifying the unique combination of values of the one or more terms of interest associated with the combination having the best score; and

setting the identified unique combination of values of the one or more terms of interest to the determined user-specified well log file data;

a user interface module that generates a user interface that renders one or more graphical representations of the determined user-specified well log file data; and

a transmission module that transmits, over one or more communication protocols and to a remote computing device, data that represents the one or more graphical representations.

2. The structured data processing system of claim 1 , wherein the well log data solver is configured to perform further operations comprising manipulating the well log file image to vertically orient the particular page of the well log file image.

3. The structured data processing system of claim 1 , wherein the well log data solver is configured to perform further operations comprising identifying, from a remote computing system, an identification of the user-specified well log file data.

4. The structured data processing system of claim 3 , wherein identifying the identification of the user-specified well log file data comprises receiving, from the remote computing system, the identification of the user-specified well log file data.

5. The structured data processing system of claim 1 , wherein the user-specified well log file data comprises well elevation data.

6. The structured data processing system of claim 5 , wherein the elevation data comprises Kelly Bushing elevation data.

7. The structured data processing system of claim 1 , wherein the particular page comprises a first page of the well log file image.

8. The structured data processing system of claim 1 , wherein the well log data solver is configured to perform further operations comprising increasing a dots per inch (dpi) value of the particular page to at least 400 dpi.

9. The structured data processing system of claim 1 , wherein the operation of cropping one or more portions of the particular page of the well log file image that comprises solid color space comprises:

cropping one or more solid white portions of the particular page; and

cropping one or more solid black portion of the particular page.

10. The structured data processing system of claim 9 , wherein at least one or more of the solid white portions or solid black portions is part of a side or a top of the particular page.

11. The structured data processing system of claim 9 , wherein the operation of cropping one or more portions of a particular page of the well log file image that comprises solid color space further comprises:

measuring a number of pixels at a top of the particular page;

vertically cropping the particular page so that a top-to-side length ratio of the particular page is 8.5 in. to 6.25 in.;

determining a text orientation of the cropped particular page; and

based on the determination, rotating the cropped particular page so that the text orientation is vertical.

12. The structured data processing system of claim 1 , wherein the well log data solver is configured to perform further operations comprising:

cropping a remaining portion of the first area excluded by the delineated size or shape of the first portion from the cropped particular page; and

cropping a remaining portion of the second area excluded by the delineated size or shape of the second portion from the cropped particular page.

13. The structured data processing system of claim 1 , wherein the operation of parsing the well log file data from the OCR'd image comprises:

parsing the OCR'd image of the first portion to determine a first set of separate values of each of one or more terms of interest included in the first representation of the user-specified well log file data; and
