You may also have all the data currently available in one file. The database has records of 147,000 wells and creates a file of around 33 MB. The link below contains the data in a comma-delimited, ASCII file that should be readable by normal spreadsheet or database software. This is a large file at 33 MB. The complete file may not fit into Excel; it is better to use the search page and select just the wells you need.
Hold your right mouse button down when you click on the link and select "Save Link to Disk" from the pop-up menu or the data file will be displayed as a web page. On Macintosh computers, hold your mouse button down and a pop-up menu should appear. (May 1, 2024)

Service and Fee Schedule

Sample Processing Fee--Except for Prepared samples, well samples submitted to the Kansas Geological Survey (KGS) for preservation are charged a processing fee for each foot of the preserved sample interval. Sample interval means from the beginning depth of the sample below land surface to the ending depth of the sample below land surface. An adjustment will be allowed for continuous sample skips that are equal to or greater than 10 percent of the total sample interval.

Sample Check-out and Return

  1. The Kansas Geological Survey (KGS) allows provisional access to check-out and examine formation samples or well cuttings providing:
    1. the account of the individual, operator or company requesting to check-out and examine samples is up-to-date and in good standing with the KGS,
    2. the individual, operator or company agrees to accept responsibility for the protection, safekeeping, care, return and payment of fees for the well samples checked out, and
    3. a request to check-out samples is made by completing a Sample Request and Check-out Form and submitting the completed form to Kansas Geologic Sample Repository (KGSR) by either mail, fax, email or in person.
  2. Payment of service fees for new or out-of-date accounts is due prior to either receipt or shipment of samples.
  3. KGS reserves the right to allow or prohibit samples to be checked-out for off-site examination.
  4. The maximum number of well sample boxes an individual, operator or company may check-out from the KGSR is 10 boxes.
  5. Sample requests or cancellations received at KGSR after 12:00 PM are considered next workday's business.
  6. Samples checked out from the KGSR and not picked up after five days are returned to the sample library and the appropriate service fees are charged.
  7. Samples not returned to KGSR by the end of the loan period are overdue:
    1. A sample check out request must be made prior to the end of the sample examination loan period to prevent an overdue fee, and
    2. Until the samples are checked in at KGSR, overdue fees accrue daily and are invoiced monthly.
  8. Special provisions, acceptable to the KGS, must be made in advance of check-out, if either:
    1. A longer loan period is required for sample examination, or
    2. more than 10 sample boxes are requested.
  9. An individual, operator or company shall either:
    1. be charged a fee, as stipulated in the Service Fee schedule, for each lost sample box, or

  10. "Damaged," means more than twenty-five percent of the samples in the box are rendered unusable for examination, as determined by KGS.

Pyrolysis Testing of Samples--Pyrolysis testing is destructive and irreversible as sufficient heat is applied to the samples causing chemical and physical decomposition. The Kansas Geological Survey (KGS) allows pyrolysis examination of formation samples or cuttings providing:

  1. The account of the operator or company requesting the examination is up-to-date and in good standing with the KGS,
  2. There is a sufficient number of wells with formation samples or cuttings, in the same quarter section (160 acre tract), to maintain the scientific and research value of the area's well samples,
  3. The pre-test volume of sample cuttings per envelope is at least 28 grams (one ounce),
  4. A maximum limit of six grams (0.212 ounce) per sample envelope may be consumed for pyrolysis or destructive testing, including any follow-up vitrinite reflectance analyses,
  5. All pyrolysis data, analyses, reports and information associated with the samples and testing are provided to the KGS at the same time the operator or company receives the test data,
  6. After testing is complete and prior to receipt of the test results, the operator or company may request in writing that all test data, analyses, reports and associated information is held confidential by KGS for a maximum period of one year from the request date, and
  7. KGS reserves the right to allow or prohibit pyrolysis examination of formation samples or cuttings.
