Technology for Core and Fluid Analyses
JOGMEC’s Technology and Research Center (TRC) owns an advanced laboratory facility, specializing in Core Analyses (CCAL and SCAL) and Fluid Analyses. These items contribute to technical support for Japanese oil development companies and to collaboration study with national oil companies in overseas.
JOGMEC has prepared to measure accurate Kr (Relative permeability) and Pc (Capillary pressure) to be caused by an advanced laboratory facilities and accumulate their operation know-how and skills. Regarding Kr, the technology is established to measure in steady-state under reservoir condition using X-ray CT scanner, regarding Pc, both the drainage and the imbibition processes are measured by two types of the porous-plate (hydrophilic and hydrophobic) and it makes to measure Pc under reservoir condition.
In the evaluate Kr and Pc, wettability of the rock samples is one of the most important property. JOGMEC conduct to try for establish the technology of the wettability evaluation procedures not only conventional methodology (Amott Harvey-Index and USBM method) but also advanced method using NMR core analysis apparatus.
On the other hand, the evaluation technology of Kr and Pc in the pore-scale is tried to establish to conduct the flooding simulations by create the pore-scale models using micro-focus X-ray CT scanner and Focused Ion Beam Scanning Electron Microscope.
JOGMEC has a laboratory and technology that can conduct with various experiments and analyses to optimize EOS (state of equation) which is important parameter for conducting reservoir simulation.
Especially for the gas injection method using associated gas and CO2 (carbon dioxide), JOGMEC accumulate technology to evaluate fluid properties using slim-tube test apparatus that can measure MMP (Minimum Miscibility Pressure) to evaluate the applicability of gas injection method, PVT apparatus to evaluate the phase behavior, densitometer, viscometer and interfacial tension measurement device. In addition, JOMEC establish a work flow for integrative evaluation of asphaltene precipitation using SARA analysis device, asphaltene onset pressure measurement device, High Pressure Microscope (which is asphaltene particle direct observation device).
