Driller's Log Conflicts With the Owner's Recollection
A driller finishes a 300-foot domestic well and files a driller's log showing first water at 180 feet, a producing zone from 220 to 260 feet, and grout from 0 to 60 feet. Six months later the owner disputes the log, claiming the driller said water was found at 90 feet and that the casing was set to 100 feet. The owner is now selling the property and the buyer's inspector is questioning the well's construction. The driller's field notes are smudged but show a static water level of 145 feet and a note about 'tight formation 90-110.' The driller must reconcile the record, respond to the inspector, and decide whether the log needs correction or clarification.
1. How should the driller evaluate whether the filed log is accurate, given the smudged field notes?
Read the worked answer
The driller should compare the filed log against all available contemporaneous evidence: the smudged field notes, drilling invoices, material delivery records for casing and grout, the permit application, and any photos. The field note 'tight formation 90-110' is consistent with encountering a non-productive zone, not first water at 90 feet, which supports the filed log's first-water depth of 180 feet. The driller should not alter a filed log based on the owner's recollection alone. If the evidence confirms the filed log, the driller explains the discrepancy. If the evidence shows an actual error, the driller corrects the record through the proper amendment process and documents why. Either way, the driller relies on records, not memory or the owner's account.
2. The buyer's inspector asks about the grout interval and casing depth. What should the driller provide and explain?
Read the worked answer
The driller should provide the filed log and any supporting records showing the grout interval from 0 to 60 feet and the casing depth as constructed. The driller should explain the purpose of the surface grout seal in protecting the well from surface contamination and in meeting construction standards, and confirm the seal was placed as recorded. If the inspector questions whether 60 feet of grout is adequate for the setting, the driller should reference the applicable construction requirements for the well's depth and setting rather than speculate. The driller should be candid about the smudged notes and the tight formation encountered, since that explains the completion design. Accurate explanation of the record supports the transaction without overstating what the well can yield.
3. Can the driller simply refile a 'cleaner' log to satisfy the buyer? Why or why not?
Read the worked answer
No. A driller's log is a regulatory record, not a marketing document. Recreating a 'cleaner' log to satisfy a buyer, especially one that shifts depths or omits the tight zone, would misrepresent the well and could constitute a false filing. The driller may only correct genuine errors through the established amendment process, with a documented basis. If the filed log is accurate, the driller should stand by it and explain it clearly to the inspector and buyer. The driller should also remind the parties that the log is a public record and that consistency between the filed log, the field notes, and the well report matters if the well is ever examined.
