Gossans Studies
Studies

Work done on the whole population, not a chosen example.

A study here means every well that met the criteria, rebuilt from the state's own filings, with the wells that did not fit reported rather than dropped. There is one so far. There will not be many, because each takes weeks and the ones worth publishing are the ones that changed somebody's mind.

What 1,459 Powder River Basin wells say about completion intensity

Every producing horizontal oil well in Converse County, rebuilt from the state's records and fitted to outturn. Proppant per well rose twenty-nine fold in thirteen years. Within a single year, doubling the sand buys about a fifth more oil, and the last increment earns eight cents on the dollar. Three completion years show no gain at all.

Two are possible now that the data supports them, and neither is written. How much of a horizontal lateral actually lies under a given section, computed from the filed surveys rather than taken from a division order. And what the record says about wells completed lightly beside neighbours completed four or five times harder, which the section screen can already find.

Both are reporting work rather than opinion, which is the only kind this site publishes while the licensing questions are open. The data page says what stands behind them and where the coverage runs out.

AlsoShorter pieces

The findings are shorter and different in kind: eight ways a production model goes quietly wrong, each argued from this work rather than from a textbook. They are not studies and are not presented as any.
