Digital Well File

A digital well file that shows which records each well is missing, hunts them through old names and earlier owners' boxes, and files a page only after a second person opens it.

The problem

Legacy well records are filed under names nobody searches for any more

A workover, a sale or a plug plan needs one record, and the search starts with today's well number. The log that matters was filed by the earlier holder under its own name, scanned with a whole box of other wells, or attached to an email nobody saved.

A document list shows what is there and not what is missing, so nobody can say which files are thin. Each project hunts the same boxes again, and when the record turns up nobody writes down where it was.

The Problem Today

A well's proof sits in scans, old names and earlier owners' boxes, and nobody can see which records are missing.

  • Each project starts overA workover or a sale hunts the same files again

The Solution

  1. The file wallEach well against the records its file must hold; white is a gap
  2. Go find itOld names, earlier owners' boxes, neighbor wells, and where it looked
  3. Is it this well?Name, date and depth checked against what the file already holds
  4. A person acceptsAn analyst proposes; the lead opens the page and accepts; the gap fills

Built-in controls

  • A second person opens the page before filing
  • Barrier records are never accepted in bulk
  • Questions on a well's safety reach a named person

What You Get

Wells and asset teams know what each file holds and get answers from the page, not from a hunt.

  • Ask one well's fileA page not yet accepted is called unconfirmed
  • Review stops on a missing recordNo barrier record, no hand-off to the well review
  • Files ready for a saleEach file goes with its gaps listed for the buyer
One gap, from white cell to filed

A digital well file gap on 14-002, found under an old name and filed

An asset engineer wants to recomplete an upper zone behind pipe, and the well's file has no cement bond log. Without a barrier record, the file cannot go to review.

demoThe wells, the boxes, the earlier holder and the people are sample data.

  1. 01Morning

    12,704 white cells: the records each well should hold and does not

    Well records analyst

    The wall puts 3,180 wells down the side and 28 kinds of record across the top. A white cell is a missing record; a cell that does not apply to that well says why. Of the 12,704 gaps, 8,413 have a page on file saying the record was made. The analyst starts where a gap blocks real work.

  2. 02Morning

    14-002 has no cement bond log, but the night's hunt found a candidate

    Well records analyst

    Clicking the bond log column lights its gaps field by field. On 14-002 the cell reads missing, found, waiting for a person. The side panel already lists each place the hunt went, so the analyst sees the trail before she opens a page. A find is only a proposal until a second person has checked it.

  3. 03Morning

    Report 49 says the log was run, so the hunt kept going until it found it

    Well records analyst

    The search record reads like a records analyst's notes. Nothing under 14-002, its old name or its slot name. The daily report says the bond log was run, so one existed. The handover list maps the old name, the box index points to six wireline print files, and 1,904 pages later page 147 of one box is the header.

  4. 04Morning

    Page 147 of a whole-box scan, filed under the earlier holder's well name

    Well records analyst

    The page shows the log header with the values the agents read marked on it: casing shoe, logged interval, top of cement in the remarks. Three checks sit beside it, and each one agrees: the old name is on the handover list, the run date falls inside the drilling dates, and the shoe matches the casing report.

  5. 0509:03

    She proposes the filing, and the screen will not let her accept it

    Well records analyst

    With all three checks agreeing, the analyst proposes filing it to 14-002. The decision panel says the checker must open the page after it is proposed before deciding. A bond log is a barrier record, so it is checked on its own, outside any lot. Her name goes on the proposal and nowhere else.

  6. 06Before 09:12

    Accept stays grey until the lead has opened the page himself

    Well records lead

    Viewing as the records lead, the accept button is disabled and the only way forward is to open the page. No timer opens it and a redraw does not count. A lead who has to check a few hundred finds a week cannot pass this one on the strength of a green tick.

  7. 0709:12

    Filed to 14-002, accepted after opening the page

    Well records lead

    He opens the page first, then accepts it at 09:12. The state reads in the file, with both names: proposed by the analyst, accepted by the lead after opening the page. The history keeps each step, and a filing can still be reopened, given a reason and the name of someone else who agrees.

  8. 0809:12

    The white cell fills and the count drops to 12,703

    Well records lead

    Back on the wall, 14-002's bond log cell is filled, and the panel shows the box, the pages and how it was checked. One gap is small, yet it is the one between an engineer and a recompletion plan, and the record of where it was found stays with the well for the next person.

  9. 09After 09:12

    The file answers top of cement at 6,180 ft, and cites the page

    Asset engineer

    The engineer asks 14-002's file where the top of cement is. The answer gives 6,180 ft from the log's remarks, the logged interval and the box and page, and says it does not judge the bond. Before the lead accepted the page, the same question called the find unconfirmed. Whether the cement is good enough goes to a named person.

Every one of the 12,704 missing well records has a state

At the start of the morning, each gap was either found, listed for an outside holder, or searched for and not found.

Where the hunt went for 14-002, step by step

Each step is on the search record, so the next project does not repeat it.

Around the file

Lots, lost records and a sale: the rest of the well file management work

Six screens the records team, the land liaison and the auditor work from.

Finds checked one by oneBarrier records and doubtful finds wait here with a five-day clock: 2,317 found, 297 late. A late barrier find keeps its well out of review.
Sampled lotsFinds from the same place, with all three checks agreeing, go in lots. The lead opens a random sample before signing, and pulling one out adds a single replacement.
Not found anywhere7,246 gaps searched for and not found, each with its search record kept and whether a page on file says the record was ever made.
What a file must hold28 kinds of record across five stages of a well's life, each with when it applies and how it is checked. Each customer loads its own standard.
Files for a sale747 files go to the buyer, each with its gaps listed. The package cannot be signed while 584 finds still wait for a person.
What the agents did overnightThe night's run on the trail: the wall rebuilt, finds checked and lotted, requests kept up to date, and the bond log found under its old name.

Who does the hunting

Seven agents map, hunt and check, and none of them files a page

A person files. The agents say what they found and where they looked.

File mapper

Reads each page, splits whole-box scans, and works out the well and the record under old names.

  • Never files a document
Gap finder

Draws the wall and decides what applies from what the file shows happened.

  • Never says a record does not apply without the passage that shows it
Hunter

Goes to find each gap and keeps the search record.

  • Never says a document never existed
Identity checker

Checks name, date and depth against the file.

  • Never accepts
  • Sends a disagreeing check one by one
Request drafter

Drafts copy requests to outside holders, with evidence each record was made.

  • Never sends
File answerer

Answers from pages, citing each value, and says unconfirmed when a page is not accepted.

  • Never answers a safety question or returns values with one
Transfer preparer

Builds a sale's package and gap list and draws the sample.

  • Never signs
  • Never includes internal notes

Six places a lost well record turns up, and the hunt reads them all

Each is read, never changed. A find reaches the file only through two people.

Document management systemSearched under today's number, old names and slot names
Well databaseDrilling dates, depths and casing to check a find against
Scanned box index and archive manifestEarlier owners' boxes, often scanned whole with many wells to a file
Email archiveContractors' attachments that were never filed
Handover listsOld well names mapped to today's numbers
Outside holdersFilings, logging company prints and earlier holders, asked by letter

What well records teams ask about a digital well file

What is a digital well file?

A digital well file holds each record a well should have across its life, from permit to abandonment. This one draws every well against the records its file must hold, so the gaps show, then hunts each digital well file gap through old names, earlier owners' boxes and email, and files a page only after a second person opens it.

How does it find legacy well records filed under old names?

It reads handover lists and box indexes to map old well and area names to today's numbers, then reads scanned boxes page by page. A match is checked on name, date and depth before anyone sees it as a find.

Can a found page be filed in bulk?

Only routine records, in lots from the same place where every check agrees, after the lead opens a random sample. Barrier records such as bond logs, casing and leak-off tests go one by one.

What happens when a record cannot be found?

The gap stays open with its search record. It can be asked for from an outside holder by letter, or recorded as lost after a proposal and a check; a lost barrier record also goes to the wells technical authority.

Can engineers ask questions of a well's file?

Yes. The answer cites the page, and calls a page unconfirmed until it has been accepted. Asking whether the cement is good enough to perforate gets a named person and no figures.

Does well records digitization replace our document system?

No. The document system, well database and archive stay as they are and are read, never changed. The file wall and the search records sit on top of them.

We will draw its wall of records and show where each missing one could still be.
