Abstract:
Matrix isolation Fourier transform spectral evidence is presented that documents the isolation of rotational isomers in an argon matrix. The spectral evidence is based on the presence of split carbonyl absorption bands in the spectra of selected derivatives of methyl acetate which do not vary in intensity with changes in the matrix-to-eluate ratios. The results compare very favorably with FT-IR data on the identical compounds obtained in the vapor phase. The low temperature of the matrix isolation experiment (10 K) allows for the observance of rotational isomers not seen at the high temperatur

Abstract:
Infrared spectra are reported of mixtures of hydrogen sulphide with chlorine or bromine in low-temperature argon or nitrogen matrices. The H2S … Cl2 and H2S … Br2 complexes were identified from the perturbed halogen stretching vibration. Absorptions due to the corresponding hydrogen halides provided evidence that reaction was occurring between the hydrogen sulphide and halogen (despite the use of a twin-jet deposition), and other reaction products were tentatively identified from the observed absorptions.

Matrix Isolation Infrared Spectroscopy has been proposed as an alternative for detection and quantification of site-specific isotopic signals. 4-hydroxy-3-methoxy benzaldehyde (vanillin) is used in an attempt to make use of its asymmetry and distinguish between the vibrations of its three functional groups, assigning structural effects to specific locations in the molecule. After achieving an apparent near-isolated state, the role of isotopic signals in the resulting splitting effects of the predicted isolated-peak structure are discussed, as well as possible significant contributions from con

Abstract:
Abstract In the most general sense, matrix isolation comprises a range of experimental techniques in which guest molecules or atoms are trapped in rigid host materials. The trapped species are prevented from diffusing, and cannot therefore undergo any bimolecular reactions, except with the host (Fig. 1.1). The host material can be a crystalline solid, a polymer, or a glass formed by freezing a liquid or solidifying a gas. The term matrix isolation is, however, most commonly used in a narrower sense: to refer to the technique of trapping molecules or atoms in solidified inert (or occasionally r

Abstract:
Abstract Near-wellbore diversion during acid fracturing or matrix acidizing is widely used to improve reservoir coverage and to save time spent on zonal isolation. It is particularly useful in offshore operations where efficiency is crucial. Diversion is typically achieved by dynamic placement of degradable solid particulates into perforations, wormholes, and/or fractures to divert the treatment fluid to understimulated zones. The diverting material must maintain integrity and mechanical strength during the operation before degrading at the downhole temperature in the presence of stimulation f

Abstract A unique cement-free geopolymer (GP) system is introduced, demonstrating high performance in CO2 environments without physical or chemical deterioration. Portland cement is chemically unstable in CO2 environments because the calcium minerals present in the set cement can react with carbonic acid, forming deleterious products such as carbonates and silica gel. These reactions compromise material integrity and lead to a loss of wellbore zonal isolation. Consequently, calcium-rich Portland cement may not be the optimal material for highly corrosive environments like carbon capture and se

Abstract One of the most cost-effective methods of completing an openhole well for oil and gas production is to gravel pack the openhole interval using sand screens and sand management devices to control the production of formation sand.

As the wells get deeper, producing from multiple zones becomes a cost-effective option, especially in offshore environments.

Abstract The steam injection method is widely deployed in heavy oil reservoirs to enhance production by reducing oil viscosity through high-temperature steam injections.

Such thermal cycling can lead to cement failures, including strength retrogression, debonding 'Inner-Outer', cracking ‘compressional tensile' leading to the loss of zonal isolation and ultimately compromising the well integr
