ABSTRACT: Previous HitPlayNext Hit Previous HitAnalysisNext Hit and Stratigraphic Position of Uinta Basin Tertiary-Age Oil and Gas Fields

Tertiary-age sediments in the Uinta basin produce hydrocarbons from five types of plays. These Previous HitplayNext Hit types were determined by hydrocarbon type, formation, depositional environment, rock type, porosity, permeability, source, and per-well recovery. Each well was reviewed to determine the stratigraphic position and producing characteristics of each producing interval.

The five types of plays are as follows: (1) naturally fractured oil reservoirs, (2) low-permeability oil reservoirs, (3) high-permeability oil reservoirs, (4) low-permeability gas reservoirs, and (5) tight gas sands.

Several fields produce from multiple plays, which made it necessary to segregate the hydrocarbon production into several plays.

The stratigraphic position of the main producing intervals is shown on a basin-wide cross section, which is color-coded by Previous HitplayTop type. This 61-well cross section has several wells from each significant Tertiary oil and gas field in the Uinta basin.
