Chemical composition and stratigraphic correlation of Mesozoic basalt units of the Newark Basin, New Jersey, and the Hartford Basin, Connecticut: Summary

Abstract: New major– and trace– element analyses of the Messozoic basalts of the Hartford Basin of Connecticut (the Talcott, Holyoke, and Hampden Basalts) indicate that the basalts are chemically very similar to the Mesozoic basalts of the Newark Basin of New Jersey (the First, Second, and Third Watchung Basalts). Our geochemical data impose some constraints on any time-stratigraphic correlation of the basalts in the two basins. We suggest that the Holyoke and Second Watchung Basalts are fractionation products of a Talcott-First Watchung parent magma. We also suggest that the Hampden and Third Watchung Basalts are synchronous fractionation products of a magma unlike any of the eastern North American basalt types described in the literature, but they may instead be the fractionation products of a magma resembling a magma of the same type as that of the Mid-Atlantic Ridge. From a petrologic standpoint, the most straight-forward time-stratigraphic interpretation is a one-to-one correlation of the three flows of the Newark Basin with the three flows of the Hartford Basin. Our geochemical and petrologic evidence is particularly supportive of time-stratigraphic correlations between the First Watchung and the Talcott basalts and between the Third Watchung and the Hampden basalts. Our data, however, are not inconsistent with the possibility that the Second Watchung may be slightly older than the Holyoke Basalt.

A pulsed NMR study of dynamics and ordering of water molecules in interfacial systems.

Abstract: The nonspherical electric charge distribution of the water molecule allows surfaces or interfaces to restrict the possible orientations of the water molecules. Nuclear magnetic resonance (NMR) spectroscopy gives a means of studying these preferentially oriented water molecules. Oriented water exhibits a doublet NMR spectrum, whereas unoriented water in a bulk liquid shows only a single line spectrum. Doublet spectra indicative of preferentially oriented water molecules have been observed in diverse systems, such as zeolites,' montmorillonoid clay^,^-^ collagen,s-n concentrated soap lo Li-DNA,\" keratin,I2 and rayon.I3 Observation of the NMR spectra of systems containing both D20 and H,O has been made for sodium hectorite clay,4 Li-DNA,\" and rayon.I3 Within experimental error, the ratio of deuteronto proton-splitting constants is the same in these latter systems. Since the physical and chemical characteristics of the substrates are vastly different, the similarity of the NMR spectra indicates that the presence of an interface is more important than the nature of the substrate in determining many structural and dynamic characteristics of water at or near an interface. The splitting can be used to study the dynamics and ordering of the water molecules in interfacial systems. The magnitude of the splitting reflects the preferential orientation or short-range order of the water molecules at the interface, and the time dependence of the splitting is sensitive to the long-range order imposed on the system by the interface. This sensitivity results from the fact that the observed splitting of an otherwise singlet NMR line is characterized by a splitting constant multiplied by a function of the orientation of the interface in the magnetic field of the NMR spectrometer. If the interface is large and planar, its angle with respect to the laboratory magnetic field is constant. A water molecule that was diffusing along this interface would have a constant direction of preferred orientation. In real systems the interface is almost always nonplanar and can be noncontinuous. In this case the interfacial orientation angle experienced by the water molecule changes as it moves along the interface; this results in a time-dependent splitting constant. The time dependence causes a broadening of the individual NMR spectral lines and can be related to a correlation time ( T , ) . This can be thought of as the time required for the interfacial orientation angle experienced by a diffusing water molecule to change by approximately one radian. We have constructed mathematical models li, l5 that reproduce the NMR measurements. The inputs to these models are the splitting constant, the correlation time, and the size of the incremental change of orientation of the interface experienced by the water molecule as it traverses its diffusional path.

Highly siliceous porous crystalline material

Abstract: A new zeolite, designated ZSM-22, is disclosed and claimed. The new zeolite has the composition, in the anhydrous state, expressed in terms of mole ratios of oxides as follows: (x)Q.sub.2 O:(y)M.sub.2/n O:(z)L.sub.2 O.sub.3 :100SiO.sub.2 wherein Q 2 O is the oxide form of an organic compound, M is an alkali or alkaline earth metal having a valence n, e.g., Na, K, Cs or Li and wherein x=0-2.0, y=0-2.0, z=0-5, and L=Al. Also disclosed are methods of preparing ZSM-22, e.g., with an alkane diamine directing agent, and uses of ZSM-22 as catalysts, e.g., in hydrocarbon conversion reactions.

The Mounds Drill-Cuttings Injection Field Experiment: Final Results and Conclusions

Abstract: This paper summarizes the results obtained from a comprehensive, joint-industry field experiment designed to improve the understanding of the mechanics and modeling of the processes involved in the downhole injection of drill cuttings. The project was executed in three phases: drilling of an injection well and two observation wells (Phase 1); conducting more than 20 intermittent cuttings-slurry injections into each of two disposal formations while imaging the created fractures with surface and downhole tiltmeters and downhole accelerometers (Phase 2); and verifying the imaged fracture geometry with comprehensive deviated-well (4) coring and logging programs through the hydraulically fractured intervals (Phase 3). Drill cuttings disposal by downhole injection is an economic and environmentally friendly solution for oil and gas operations under zero-discharge requirements. Disposal injections have been applied in several areas around the world and at significant depths where they will not interfere with surface and subsurface potable water sources. The critical issue associated with this technology is the assurance that the cuttings are permanently and safely isolated in a cost-effective manner. The paper presents results that show that intermittent injections (allowing the fracture to close between injections) create multiple fractures within a disposal domain of limited extent. The paper also includes the conclusions of the project and an operational approach to promote the creation of a cuttings disposal domain. The approach introduces fundamental changes in the design of disposal injections, which until recently was based upon the design assumption that a large, single storage fracture was created by cuttings injections.
