Differences of Organic Matter Types of High Maturity Marine Organic-Rich Shale from Wufeng-Longmaxi Formation: Implication for Shale Gas “Sweet Spots” Prediction

open access: yesEnergy Exploration & Exploitation, 2023
Based on the identification of visual kerogen assessment, a subdivision method of organic matter types was proposed. Combined with GR curve, the distribution was further studied, the relationship between shale reservoir parameters and organic matter ...

Preparation, physical-chemical characterisation and cytocompatibility of calcium carbonate cements [PDF]

open access: yes, 2006
The feasibility of calcium carbonate cements involving the recrystallisation of metastable calcium carbonate varieties has been demonstrated. Calcium carbonate cement compositions presented in this paper can be prepared straightforwardly by simply mixing

Experimental investigation of calcium carbonate mineralogy in past and future oceans [PDF]

open access: yes, 2011
Inorganic marine calcium carbonate formation and mineralogy varies significantly concurrent with the solution composition. During the Phanerozoic, due to oscillations in the seawater composition, this resulted in the formation of either dominantly ...

Review of Surfactant Enhanced Oil Recovery in Carbonate Reservoirs [PDF]

open access: yes, 2013
About half of proven conventional oil reserves are in carbonate reservoirs. Due to complex structures, formation heterogeneities and oil-wet/mixed wet conditions, etc., the oil recovery factor in carbonate reservoirs is very low.
