“…In Table Rock field sandstones typically coarsen upwards from very-fine to medium and are well to very-well sorted with cross laminations in high-energy deposits and bioturbation structures elsewhere (Merewether, 1983). Marine depositional environments represented in core we examined are primarily middle- to lower-shoreface facies (DeJarnett et al 2001) (Table 1). Vertically, the sampled interval includes c .…”

“…In this paper we revisit a key horizontal well core suite from the eastern Greater Green River Basin, the Rock Island 4-H and Sidewinder 1-H horizontal cores that sample the faulted, basement-cored Table Rock anticline in Upper Cretaceous Frontier Formation sandstones (DeJarnett et al 2001) (Figs 1, 2). Fracture studies based on these cores (Lorenz, Billingsley & Evans, 1998; Lorenz & Mroz, 1999; DeJarnett et al 2001; DeJarnett, Lim & Calogero, 2001; Lorenz, Krystinik & Mroz, 2005) influenced views on the character of subsurface fractures in the Laramide basement-involved province, Wyoming and their effects on fluid flow (e.g. Billingsley, 2001; Lorenz, 2003; Camp, 2008; Coleman, 2008).…”

-Fracture-hosted porosity and quartz distribution along with crack-seal texture and fluid inclusion assemblage sequences in isolated, bridging quartz deposits show that open fractures can persist through protracted burial and uplift in foreland basins. Fractures oriented at a high angle to current maximum compressive stress remain open and were weak mechanical discontinuities for millions of years even at great depth. Upper Cretaceous Frontier Formation sandstones in the basementinvolved (Laramide) Table Rock anticline, eastern Greater Green River Basin, Wyoming sampled by two horizontal wells (cut parallel or nearly parallel to bedding and at a high angle to steeply dipping fractures) have 41.5 m of rock in four cores at depths of 4538-4547 m. Cores intersect older E-striking Set 1 fractures are abutted by or locally cross-cut by N-striking Set 2 fractures. Both sets contain quartz and porosity. Sequenced using quartz crack-seal cement texture maps, Set 1 fluid inclusion assemblage (FIA) trapping temperatures increase progressively from 140 to 165°C then decrease to c. 150°C, compatible with fracture opening over c. 15 Ma during rapid burial followed by uplift in Eocene-Oligocene time. Set 2 opened at c. 160°C, probably near maximum burial. After a period of quiescence, Set 2 reopened at c. 5 Ma at c. 140°C, on a cooling trajectory. Intermittent Set 2 movement could reflect local basement-involved fault movement, followed after a pause by further Set 2 reactivation in the modern stress field during uplift. Interpretations are sensitive to available burial/thermal histories, which have considerable uncertainty.

“…The GGRB is a relatively impermeable basin relative to spacing rules. Most oil and gas fields in the GGRB are "tight"formations, consisting of relatively impermeable rock, meaning that oil and gas cannot flow long distances underground (Nelson, Ewald, Santus, and Trainor, 2009;DeJarnett, Lim, and Calogero, 2002). In figure A13 I graph permeability from a number of wells using figures taken from the 1979 and 1992 editions of the Wyoming Oil and Gas Fields Symposium (Wyoming Geological Association, 1979, 1992.…”

Patchwork Policies, Spillovers, and the Search for Oil and Gas

The United States has a complex patchwork of mineral ownership, where rights to oil and gas may be owned by the federal government, state governments, or private agents. I show why the policies imposed by one owner have theoretically ambiguous spillover effects on the drilling and production outcomes of neighboring plots of land. Exploiting a natural experiment in Wyoming with exogenous ownership assignment, I find significant spillovers: federal land close to state land has a lower probability of drilling than federal land far from state land.
