Jn some cases there may be a milestone where an item is being fabricated. maintenance is being performed on a facility, or a docume nt ts being issued through a formal document control process where it specifically calls oul a formal review of rhe document. In these cases, documentation (e.g., inspection report, maintenance request, work planning package documentation or the documented review of the issued document through the document control of the completion of the activity, along with the Document Cover Sheet, is sufficienJ to demonstrate achieving the milestone. /f QRL I, 2. or 3 is not. assigned, then the Lab I Participant QA Program (no additional FCT QA requirements) box must be checked, and the work is understood to be performed and any deliverable developed in conformance with the respective National Laboratory I Participant, DOE or NNSA-approved QA Program.

Room D was an in-situ, isothermal, underground experiment conducted at the Waste Isolation Pilot Plant between 1984 and 1991. The room was carefully instrumented to measure the horizontal and vertical closure immediately upon excavation and for several years thereafter. Early finite element simulations of salt creep around Room D under predicted the vertical closure by 4.5⇥, causing investigators to explore a series of changes to the way Room D was modeled. Discrepancies between simulations and measurements were resolved through a series of adjustments to model parameters, which were openly acknowledged in published reports. I am indebted to a number of people for ushering me into the world of rock salt mechanics. J. Guadalupe Argüello invited me take his place on Joint Project III, and was incredibly patient with all of my questions during the transition period. Frank Hansen has been an invaluable resource for the science behind the modeling, for the history of WIPP, and for promoting the Joint Project activities. James Bean helped me understand the Munson-Dawson material model, and continues to give me suggestions on how to make simulations run e ciently. Courtney Herrick and Michael Schuhen have provided many crucial bits of information from their first-hand knowledge of WIPP. Christi Leigh saw the importance of this work and found funding to support it. John Holland and Frank Hansen reviewed this report and provided useful feedback.

“…The value for the Newtonian viscosity was derived from available literature on deep solution salt mining (van Heekeren et al, 2009). The chosen Newtonian viscosity used in the simulations agrees, within one order of magnitude, with the experimental data obtained during very slow creep tests under low differential stresses (< 1 MPa) reported by Bérest et al (2005Bérest et al ( , 2014. We adopted the same value for simulations of the steady-state creep in salt as low differential stresses are also expected to develop in the Zechstein salt caprocks as a consequence of pore pressure changes in the main gas reservoir.…”

-Natural gas from the Załęcze gas field located in the Fore-Sudetic Monocline of the Southern Permian Basin has been produced since November 1973, and continuous gas production led to a decrease in the initial reservoir pressure from 151 bar to about 22 bar until 2010. We investigated a prospective enhanced gas recovery operation at the Załęcze gas field by coupled numerical hydro-mechanical simulations to account for the CO 2 storage capacity, trapping efficiency and mechanical integrity of the reservoir, caprock and regional faults. Dynamic flow simulations carried out indicate a CO 2 storage capacity of 106.6 Mt with a trapping efficiency of about 43% (45.8 Mt CO 2 ) established after 500 years of simulation. Two independent strategies on the assessment of mechanical integrity were followed by two different modeling groups resulting in the implementation of field-to regional-scale hydro-mechanical simulation models. The simulation results based on application of different constitutive laws for the lithological units show deviations of 31% to 93% for the calculated maximum vertical displacements at the reservoir top. Nevertheless, results of both simulation strategies indicate that fault reactivation generating potential leakage pathways from the reservoir to shallower units is very unlikely due to the low fault slip tendency (close to zero) in the Zechstein caprocks. Consequently, our simulation results also emphasise that the supra-and subsaliniferous fault systems at the Załęcze gas field are independent and very likely not hydraulically connected. Based on our simulation results derived from two independent modeling strategies with similar simulation results on fault and caprock integrity, we conclude that the investigated enhanced gas recovery scheme is feasible, with a negligibly low risk of relevant fault reactivation or formation fluid leakage through the Zechstein caprocks.Résumé -Des simulations numériques de récupération assistée de gaz sur un gisement de gaz de Załęcze en Pologne confirment les capacités de stockage de CO 2 élevées et l'intégrité mécanique dudit gisement -Le gaz naturel du gisement de Załęcze, situé dans la structure monoclinale de la région des Sudètes au niveau du Bassin Permien sud, est produit depuis novembre 1973, moyennant quoi la production de gaz continue a donné lieu à une diminution de la pression initiale du réservoir de 151 bar à environ 22 bar en 2010.
