Thermodynamics and kinetics studies of formation and decomposition of clathrates hydrates of methane, carbon dioxide and their mixtures using a differential heat flux calorimeter
A high pressure heat flux calorimeter in isobaric, temperature-ramping mode has been used to measure the solubility of pure methane, pure carbon dioxide and methane-carbon dioxide mixtures. The solubility measurements ...
Wettability/spreading of alkanes at the water-gas interface at elevated temperatures and pressures
A model consisting of the Hamaker-Lifshitz theory is used to calculate the spreading transition of alkanes at the water-gas interface. In the current work, the theory is extended to include effects of the temperature and ...
Estimation of relaxation time distribution for NMR CPMG measurements
We use a MARAN-2 laboratory NMR spectrometer for making measurements using the CPMG pulse sequence for estimating the spin-spin or T$\sb2$ relaxation time distribution. Algorithms are developed for estimating the relaxation ...
Elucidation of the formation and decomposition of clathrate hydrates of natural gases through gas solubility measurements
Through isobaric temperature ramping experiments, the solubility of pure methane, ethane, propane, carbon dioxide gases and a methane-propane gas mixture in pure liquid water has been measured. The experiments are conducted ...
Estimation of rock properties by NMR relaxation methods
Two often used permeability models, which are based on logarithmic mean of relaxation time distribution and irreducible water, were examined. The model based on irreducible water was found to be more suitable than the model ...
