VDH presents the changes made and describes his life on board during this round the world trip.Ĭan you tell us why you chose a Rustler 36 and why this one in particular? This Rustler 36, a 1980 sailing boat with a long keel, which has just sailed around the world in 211 days, is surprisingly fresh. Essential components of this model include: (1) widespread Late Triassic/Early Jurassic evaporite recrystallization (2) accumulation of deep-basin brines isolated from meteoric recharge (3) evaporite dissolution by meteoric waters flowing in carbonates and sulfates interbedded in the uppermost Permian section and at the basin margin (4) lateral rather than vertical infiltration of pre-Holocene meteoric waters in the uppermost Permian section and (5) climatic conditions presently less conducive to recharge than in the Late Pleistocene.24 hours after his triumphant arrival on the Golden Globe Race 2018, Jean-Luc Van den Heede, the 73-year-old sailor, welcomes us aboard his boat. The resulting synthesis of data and current hypotheses concerning the origin, composition and history of waters in the evaporite rocks and related units of the Delaware Basin provides a tentative conceptual model for the behavior of the water-rock system since the deposition of the evaporites in the Permian. These data were evaluated in order: (1) to determine the stability of the evaporite mineralogy over geological time (2) to compare the aqueous geochemistry with host rock mineralogy (3) to delineate the nature and timing of water-rock interactions, such as dissolution and recrystallization (4) to determine the geological and climatic conditions that have governed groundwater recharge.
These data were compiled for the geological and hydrological characterization of the Waste Isolation Pilot Plant (WIPP), which is excavated in the evaporites of the Salado Formation. Our analysis that exploits remote sensing data and numerical models provides a clue as to understanding the subsurface hydrogeological process responding to the oil and gas activities and an indirect leakage monitoring method to supplement current infrequent leakage detection.Īn extensive geochemical data base, including analyses of major and minor solutes, mineralogical studies of core samples, and isotopic studies of waters, carbonates and sulfates, has been assembled for evaporites and related rocks in the northern Delaware Basin of southeastern New Mexico. The Rustler Aquifer, within the zone of the effective injection depth, has been used as a source of freshwater for irrigation and livestock wastewater leaked into this aquifer may possibly contaminate that freshwater. The most reasonable explanation is that the well was experiencing leakage due to casing failures and/or sealing problem(s). Results from both elastic and poroelastic models indicate that the effective injection depth is much shallower than the depth reported to the Texas Railroad Commission (RRC). Given the initial estimates of wastewater injection, forward poroelastic finite element models were applied to simulate stress/strain and displacement fields and to estimate the effective injection volume and depth, so as to ultimately understand the subsurface geomechanical processes and provide insight into the local hydrologic properties of the strata in the well location.
Inverse elastic models were first used to calculate the injection depth and volume. High correlation between the observed deformation and the injection volume suggests that the uplift was caused by wastewater disposal in the well. Using Interferometric Synthetic Aperture Radar (InSAR) to observe ground deformation in the Ken Regan field, West Texas, we detected surface uplift that occurred near a wastewater disposal well from 2007 to 2011. Wastewater, a byproduct of oil and gas production, is injected into disposal wells.
