...) from 2017 to 2018, and both drilling and full coring operation were conducted at the former mantle-crust boundary (now exposed). Full suite of wireline log data was acquired with good quality in the drilling well and excellent quality core samples were continuously taken in the coring borehole nearby...

... Abstract To understand characteristics of deep seismogenic faults in the plate convergent margins, we used P- and S-wave velocities (Vp and Vs) of the digital rocks extracted from core samples of ancient plate boundary fault at Nobeoka in Kyushu, southwest Japan. We constructed 3D digital rock...

... 0.6486 M-oil 8.3740 U-oil 7.9230 n-Decane 0.6632 2.1.2 Core Data (1) Length, Porosity and Air Permeability Berea sand stone core samples were used in these experiments. The core data are presented in Table 2.1.2-1, where, D is a diameter, L is a length, Vp is a pore volume, is a porosity and kair...

...The 22nd Formation Evaluation Symposium of Japan, September 29 - 30, 2016 -1- EXPERIMENTS OF MICRO-BUBBLE CO2 EOR USING BEREA SANDSTONE CORE SAMPLES Hiroko Hiramoto1, Kei Kukuu1, Masanori Kurihara1, Takashi Akai2, Yasutomo Takakuwa2, Ko Sato2, Yoshihiro Tsuchiya2 Naoto Araki3 and Seiji Shirai3 1...

... to conduct a detailed analysis on existing core samples and image log data to identify and understand heterogeneous reservoir properties that will be critical information for future field development. At the beginning of the workflow, raw data from the field were carefully processed though accurate depth...

... been applied to different types of vuggy carbonate rock core samples. 3D distributions of CT number of the samples, which consists of 0.4-mm cubic voxels, are converted into 3D porosity distributions, using the partial volume effect (i.e., a linear relationship between CT number and porosity...

... the step-by-step approach, we can detect the flow rate reduction and can estimate the threshold capillary pressure. Until now, several types of fluid not only CO2 but also N2 and CH4 were injected into the core samples under different conditions and showed the values of the different threshold capillary...

... was cored from 500 m-below sea floor (BSF) in ocean depths of over 3500 m. Obtaining high recovery and quality core samples is crucial for comprehensive and accurate analysis. This study analyzes the results of the core recovery ratio and quality of basement samples at coring site C0012G in order...
