CH4mber field notes https://ch4mber.io/field-notes Dated updates from CH4mber’s field work on orphaned wells and on the methodology for crediting them. en A few orphaned wells carry most of the methane, and the obvious clues do not find them https://ch4mber.io/field-notes/few-wells https://ch4mber.io/field-notes/few-wells Wed, 14 Oct 2026 12:00:00 GMT Research Of 1,042 Oklahoma orphaned wells we tested, 17 hold 80% of the methane. Most signals meant to predict which ones did not hold up. How long a leak lasts depends on a pressure nobody has measured https://ch4mber.io/field-notes/will-it-keep-leaking https://ch4mber.io/field-notes/will-it-keep-leaking Wed, 14 Oct 2026 12:00:00 GMT Research A leak is a choke on a tank. The choke sets the rate; the tank sets how long. Why the answer turns on an unmeasured pressure, and what would settle it. How orphaned wells are found and their methane measured, from orbit to the wellhead https://ch4mber.io/field-notes/orbit-to-wellhead https://ch4mber.io/field-notes/orbit-to-wellhead Wed, 14 Oct 2026 12:00:00 GMT Research A guide to the tools that find orphaned wells and measure their methane, from satellites to the wellhead, and what our test of two satellite products showed. Most of the wells we could not reach were stopped by a person, not the ground https://ch4mber.io/field-notes/the-gate-is-a-person https://ch4mber.io/field-notes/the-gate-is-a-person Wed, 14 Oct 2026 12:00:00 GMT Field We built a terrain score to predict which orphaned wells a truck could reach. Tested against 127 field visits, it predicted nothing. The gap was people. Most orphaned wells have no production record to fit a decline curve to https://ch4mber.io/field-notes/missing-record https://ch4mber.io/field-notes/missing-record Wed, 14 Oct 2026 12:00:00 GMT Research 83% of Oklahoma's listed orphaned wells predate the electronic production record. Where a history survives, a decline fit can flip sign. Once a well is plugged, its leak can never be measured again https://ch4mber.io/field-notes/baseline https://ch4mber.io/field-notes/baseline Wed, 14 Oct 2026 12:00:00 GMT Field We measured Schnitzer #2 on four dates before we plugged it. After the cement, that record is all the evidence of its leak there will ever be. Opening an orphaned well to measure its leak measures something else https://ch4mber.io/field-notes/as-found https://ch4mber.io/field-notes/as-found Wed, 14 Oct 2026 12:00:00 GMT Methodology A leak and an opened-well flow test on the same orphaned well can differ many times over, and credits scale with whichever one a project measured. When to stay in a survey area, when to leave, and when the data cannot say https://ch4mber.io/field-notes/uncertain-is-an-answer https://ch4mber.io/field-notes/uncertain-is-an-answer Wed, 14 Oct 2026 12:00:00 GMT Field The written rules our crews use to work an area harder or walk away, why they count wells measured, and why 'uncertain' is a verdict of its own.
