Well Report Search

Well report search that reads a platform’s mud logs, final well reports and studies, scans and handwriting included, and answers with the wells hung by depth.

The problem

The show is in a scanned mud log, and the final well report says none

For one sand on one platform, the answer is spread across mud logs, final well reports, log prints and old studies, most of them scans and some in handwriting. A geologist opens one well file after another, converts each depth from the survey or mixes measured with vertical, and types a table to draw the correlation panel by hand.

Then the files argue. One author’s top pick puts a show inside the sand and another’s puts it above. A well whose boxes were lost in a move simply does not turn up, so its gap reads as no show. The disagreement gets settled in a hallway, and nobody writes down why.

The Problem Today

Shows and tops sit in decades of scanned reports and handwriting that ordinary search never reads.

Read by hand today

  • Mud logs
  • Reports
  • Log prints
  • Studies
  • Shows nobody keyedA mud log’s show never reaches the well database
  • Reports that disagreeTwo top picks move a show in or out of a sand

The Solution

  1. Ask in your own wordsA sand, a well, a depth or the words on a page; rights checked first
  2. Each page readScans and handwriting read page by page, each reading with a confidence
  3. Drawn by depthEach show placed below sea level from the well’s own survey
  4. Disagreements ruledTwo reports that disagree are both shown; a senior geoscientist rules

Built-in controls

  • Rights by license and partner, before reading
  • Nobody signs a ruling they proposed
  • Audit trail of each question, page and ruling

What You Get

Geologists move a target with the pages behind it in view, and each doubt settled and signed.

  • Plain gaps, never filledA well with no records is drawn hatched, not clean
  • Evidence for the target reviewEach well, its page and its ruling in one sheet
One question, nine screens

One sand, fourteen wells and a 48 ft top pick, in a well report search

Sidetrack target T-2 aims at the G50 near the crest, where a 2004 review recommends a second look for bypassed oil. First, the geologist asks where anyone has seen shows in that sand.

demoWells, people, pages and depths on these screens are sample data from one invented platform.

  1. 01Before the target moves

    1,823 pages read, and the answer drawn as a correlation panel

    Exploration geologist

    She types the question in her own words. Seven agents check her rights, read 1,823 pages from 23 documents, place each finding from the well’s own survey and draw the wells west to east, hung below sea level, with Fault F3 dashed. Seven wells show, four record none, two disagree, and 14-019 is hatched as cannot say.

  2. 02On the 14-007 pin

    The show at 8,412 ft is on page 31 of a mud log scanned in 1997

    Exploration geologist

    One click opens the page beside the panel, passage lit: 15% dull yellow fluorescence, slow streaming milky cut, total gas 38 units over 6. It was read at 91%, and the depth sum below turns 8,412 ft measured into 8,192 ft below sea level.

  3. 03The disagreement

    The 1998 final well report says no shows, and a 2004 review moves the top

    Exploration geologist

    The final well report puts the G50 top at 8,446 ft and writes no hydrocarbon shows in it, leaving the show 34 ft above the sand. The review re-picks the top at 8,398 ft on the gamma ray, so the show sits 14 ft inside. Until someone asks for a ruling, each answer shows both.

  4. 04Second opinion

    On log print run 2, both picks can be argued

    Petrophysicist

    She asks for a second opinion, and the petrophysicist must open all three sources before proposing anything. On the print the gamma ray falls from 92 to 64 API units at 8,398 ft, with shaly sand to 8,446 ft and clean sand to the base at 8,484 ft. One author took the first sand, the other the clean sand.

  5. 05Proposing

    Three possible rulings, each showing what it does to the count

    Petrophysicist

    With the sources open, three rulings appear with their effect: the earlier pick counts 14-007 as no show, the later pick counts it as a show, and neither leaves it disputed. He chooses the later pick. Reasons come with the ruling chosen, so his cannot argue the other way, and he adds a line from the print.

  6. 06Before signing

    His signature waits on three pages he has to open himself

    Senior geoscientist

    He gets the proposal, its reason and the line from the print. Over a greyed-out button the screen asks him to open 3 more pages before he rules, and says waiting will not change that. What the petrophysicist opened does not count for him. A proposal that does not hold up can go back to its author, with his reason.

  7. 07The ruling

    The later pick stands, signed by someone who did not propose it

    Senior geoscientist

    Having read the final well report, the review and the print for himself, he signs. The card names him as ruler and the petrophysicist as proposer, with the reason: the gamma ray break is at 8,398 ft. Request, proposal and signature stay in order in the history, and he can reopen it if new data arrives.

  8. 08Back on the question

    The well report search now answers 8 of 14, with the ruling under its name

    Exploration geologist

    Asked again, the panel redraws. 14-007 hangs on the 2004 top, its 1998 pick greyed, its show carrying the ruler’s initials. The sentence counts 8 wells with shows, 4 with none, 1 that cannot say and 1 still disputed, 14-001. West of the fault each show sits above about 8,320 ft below sea level, where the review reads an oil-water contact.

  9. 09For the target review

    A draft evidence sheet for T-2 that keeps its open items open

    Exploration geologist

    One row per well: the G50 show, the top below sea level, the source page and any ruling. 14-001 reads reports disagree, not ruled, and 14-019 reads cannot say. She prepares it; the senior geoscientist opens it before he issues it. Reopen a ruling on a well within a mile of T-2 after issue, and the sheet reopens too.

Well 14-007: two tops 48 ft apart, and a show that lands either side

Depths come from the well’s own survey: vertical to 2,000 ft, a build of 1.5° per 100 ft to 12°, then a straight hold, with the rotary table 92 ft above sea level.

demoSample data, from the working solution.

Four wells a list of files would have counted as clean

Each sits on the same panel, with the page that says so.

Nothing below 1,800 ft

The boxes for 14-019 were lost in a move. It is hatched as cannot say, and drawn as a gap.

Fluorescence that may be calcite

The 1988 mud log on 14-001 logs a slow cut. The sample check found a colorless cut on calcite cemented grains, so both readings stand until someone rules.

A none that rests on a summary

Only the end-of-well summary survives for 14-012, its top just above the contact, and the answer says so.

Samples washed out

14-041 lost its samples from 8,470 to 8,490 ft. The gap is written beside its none.

Around the answer

Calcite, lost boxes and closed records, on the same G50 answer

The library, the rights and the queue behind that one G50 answer. Choose a screen to enlarge it.

Flattened on the G50 topA toggle re-hangs the wells on the top of the sand, so shows read against the sand instead of against depth. After the ruling, 14-007 hangs on the 2004 top.
Where the records stopOnly daily reports 1 to 12 survive for 14-019, scanned and handwritten. Its mud log and final well report went with the lost boxes, so the well stays cannot say.
Oil or mineralOn 14-001 a 1988 mud log logs 10% yellow fluorescence with a slow cut, while page 44 of the 2004 review reads it as mineral, a colorless cut on calcite.
Held, counted and namedOf 437,118 documents, 58% are scanned images. 1,946 files are held: 412 password protected, 288 damaged and 1,246 too faint, each with a request for a clean copy.
Rights before readingA partner’s venture records and a deal room are closed to the geologist, and licensed seismic reports are view only. Closed records drop out before any search.
The rulings queue340 disputes open across the library and 1,028 ruled, each on a 10 working-day clock: tops, contacts, a core depth shift, trip gas against formation gas.

What geologists ask about well report search

What is well report search?

Well report search answers geoscience questions from well, seismic and study reports, with each answer cited to its page. This one reads mud logs, final well reports, log prints and studies, scans and handwriting included, and draws the answer as a correlation panel of wells hung by depth, each pin on the page that holds it.

How does it find hydrocarbon shows in old mud logs?

Each description, scanned or typed, is read with a confidence, and readings under the line wait for a person. Shows are kept in their own words: fluorescence, cut, stain, gas over background. Each is then placed below sea level from the well’s own survey, with the sum shown.

What happens when two reports disagree on a top?

Both are shown and neither is picked. Someone asks for a ruling, a geoscientist opens each source and proposes one with a reason that fits it, and a senior geoscientist opens the same pages and signs. The answer then repeats the ruling under his name, on the panel, in the sentence and on the evidence sheet.

Is this a well log search?

It reads log prints as pages, beside mud logs, final well reports, core reports and studies, and answers with shows and tops at depth, each tied to its page, in place of a list of files to open.

What does it say when a well has no records?

That the records cannot answer. A well whose file stops far above the sand is hatched and counted as cannot say. A file that could not be read is held, counted and named, so a gap is drawn as a gap and is not read as a clean well.

Can it read legacy well data from scanned boxes?

Yes. Scans, faint prints and handwriting are read page by page, each reading with a confidence. Files that are password protected, damaged or too faint are held and counted, with a request to the file’s owner, the document system or the records store for a clean copy.

Who can see partner and licensed records?

Rights by license and partner apply before anything is read. A closed record is left out, and the answer says some records are closed and names the data manager, without saying what they hold.
