Abstract:
Carbonate cements in clastic rocks capture a geochemical record of burial processes. As such, much of our understanding of clastic diagenesis and subsurface microbial activity is influenced by studies of carbonate cemented horizons and concretions. Furthermore, their presence can have a significant impact on clastic reservoir quality. However, the formation of cement bodies is poorly understood. A part of this problem is that studies investigating carbonate cements have historically been limited by the δ18Ocarbonate being dependent on both the carbonate precipitation temperature and δ18Oporewa

Abstract:
The carbon dioxide (CO2) system is the primary buffer in seawater which controls oceanic pH. Changes in the marine CO2 system affect a number of processes such as metal speciation, mineral saturation states, auditory responses in fish, and primary productivity rates. Increased atmospheric concentrations of CO2 from human activities (e.g. burning of fossil fuels, deforestation, and cement production) has led to a global decrease in surface ocean pH termed anthropogenic ocean acidification. One particular concern in response to increased oceanic CO2 is a substantial decrease in the calcium carbo

Abstract:
Recent studies have demonstrated that marine bony fish (teleosts) precipitate inorganic calcium carbonate in their gut as a by-product of osmoregulation, subsequently excreting it into the open water column as loosely aggregated millimetre-scale pellet. These studies have primarily focused on physiological aspects of this process and the fate of resulting carbonates in pelagic settings, which is likely to be dissolution at depth. However, the implications of such carbonate production in shallow tropical and sub-tropical carbonate provinces has also begun to be considered, and it is thought tha

The calcination of calcium carbonate in a cement or a lime kiln uses approximately two to four times the theoretical quantity of energy predicted from thermodynamic calculation depending upon the type of the kiln used (1.4 x 10^6 Btu/ton theoretical to 6 x 10^6 Btu/ton actual). The objective of this research was to attempt to reduce the energy required for the calcination by 1. decreasing the calcination temperature of calcium carbonate, and/or 2. increasing the rate of calcination at a specific temperature.

Abstract:
Nuclear Magnetic Relaxation Dispersion (NMRD) is strongly sensitive to the microscopic wettability of oil and brine bearing carbonate rocks. Exploring a very large range of low frequency enables isolating the typical NMRD dispersion features, 1/T1Surf, associated to the different processes of molecular surface dynamics. This allows a separation of the surface and bulk microdynamics of oil and water even for a biphasic saturation of petroleum rocks. Several surface dynamical parameters were determined and related to the concept of microscopic wettability of oil and water in porous media.

The characterisation of karstified carbonate reservoirs is a challenging task due to: (a) Complex fault systems; (b) Amplitude anomalies (karst features) and (c) Strong heterogeneity. To deal with these difficulties, I have developed three techniques targeting at the karstified carbonate reservoirs from Tarim basin: (a) Fracture detection based on seismic coherence can be affected by dipping reflectors and noise. A robust algorithm is developed, where dip is used to eliminate the impact of dipping reflectors and a pseudo-multichannel appraoch is employed to improve robustness (good performance

Reliable measurements of the thermodynamics of the carbonate system are needed to better understand the CO2 system in natural waters. New measurements of the carbonic acid pK1* and pK2* in seawater have been made over a wide range of temperatures (1 to 50°C) and salinities. The commonly used CO2 constants of Mehrbach et al., (1973) were limited to salinities (19 to 43) and temperatures (2 to 35°C). They cannot be used to study estuarine or fresh waters. The results of these measured pK1* and pK2* values are in good agreement with those determined using the Miami Pitzer equations (Millero a

Autocausticizing, a new method to regenerate sodium hydroxide from the sodium carbonate, is intended to replace the conventional Kraft Recovery System which uses calcium hydroxide produced in a lime kiln for this purpose.

Thus autocausticizing can eliminate the need for a lime cycle and hence reduce the Kraft process capital and operating costs.
