“…General descriptions of the impurity content of the dome [Hart et al, 1981, Section 61, taken from sources other than the Phase 111 wells, have suggested about 3% insolubles, based on minimal data. There have apparently been no specific evaluations of anhydrite.…”

“…The models are based on the original site characterization report (table 1: Hart et al, 1981), but selected information from the site characterization update report (table 1 (Magorian and Neal,1988) have been incorporated as described below. The model generated by creating and merging two separate geologic surfaces is shown in figure 4, and the model constructed simply by closing the top of the dome to the centroid of the highest structural contour is presented in figure 5.…”

“…In this case because of the coarse structure-contour interval used in the site characterization report of Hart et al (1981), the dome-top elevation is represented at 1,250 ft below sea level, in contrast to the known cavern intersections of the top-of-salt surface in roughly the same horizontal locations of some to -1,600 ft. The implication is that the -ft dome-top elevation is purely an artifact of the simplified, non-geology-based modeling technique, and that it is preferable to use the approach based on actual geologic data when it is available (see next paragraph).…”

“…This model conversion has been undertaken as-is, with the full realization that the existing site characterization reports are modestly dated and the interpretations therein are one to two decades old (Hogan, 1980a(Hogan, , 1980bWhiting et al, 1980;Hart et al, 1981;Magorian and Neal, 1988;Magorian et al, 1991;Neal et al, 1993Neal et al, , 1994.…”

3 SAND2003-3300Unlimited A new modeling algorithm has been developed to overcome limitations of many standard geological modeling software packages in order to deal with structurally overhanging salt margins that are typical of many salt domes. This algorithm, and the implementing computer program, make use of the existing interpretive modeling conducted manually using professional geological judgement and presented in two dimensions in the original site characterization reports as structure contour maps on the top of salt. The algorithm makes use of concepts of finite-element meshes of general engineering usage. Although the specific implementation of the algorithm described in this report and the resulting output files are tailored to the modeling and visualization software used to construct the figures contained herein, the algorithm itself is generic and other implementations and output formats are possible.The graphical visualizations of the salt domes at the four Strategic Petroleum Reserve sites are believed to be major improvements over the previously available two-dimensional representations of the domes via conventional geologic drawings (cross sections and contour maps). Additionally, the numerical mesh files produced by this modeling activity are available for import into and display by other software routines. The mesh data are not explicitly tabulated in this report; however an electronic version in simple ASCII format is included on a PC-based compact disk.

“…Other space is available to the north (outside the DOE property boundary), and probably has better potential for expansion. Although modeling by Stein and Rautman (2004) shows the northern edge of the dome to be much less constrained (fewer data points to indicate where the salt is) than the southern portion, both the original site characterizations report (Hart et al, 1981) and its most recent update, which includes a high resolution seismic survey (Neal and Magorian, 1993), suggest that the site is geologically superior for SPR cavern development. …”

Abstract3-D finite element analyses were performed to evaluate the structural integrity of caverns located at the Strategic Petroleum Reserve's Big Hill site. State-of-art analyses simulated the current site configuration and considered additional caverns. The addition of 5 caverns to account for a full site and a full dome containing 31 caverns were modeled. Operations including both normal and cavern workover pressures and cavern enlargement due to leaching were modeled to account for as many as 5 future oil drawdowns. Under the modeled conditions, caverns were placed very close to the edge of the salt dome. The web of salt separating the caverns and the web of salt between the caverns and edge of the salt dome were reduced due to leaching. The impacts on cavern stability, underground creep closure, surface subsidence and infrastructure, and well integrity were quantified. The analyses included recently derived damage criterion obtained from testing of Big Hill salt cores. The results show that from a structural view point, many additional caverns can be safely added to Big Hill.
