Fracture imaging using Image Point transform and midpoint imaging of RVSP data
이창현,박권규,Toshiyuki Matsuoka,Toshifumi Matsuoka 한국지질과학협의회 2010 Geosciences Journal Vol.14 No.4
An Image Point (IP) transform integrates along a hyperbolic path and converts data to a point in the IP domain so that the reflection events are accumulated to the image point for given sources in the IP domain. In addition, the image point by definition is uniquely determined and the midpoints between sources and the image points always lie on the reflector surface. Exploiting these two facts, the image point transform technique for Vertical Seismic Profile (VSP) to reverse VSP (RVSP) data is expanded to suggest a new method called the midpoint imaging method for imaging reflectors such as fractures. Applying the transform with synthetic data for Two-dimensional (2-D) models with single reflector and two reflectors, we confirm and demonstrate that the reflection events are clearly identifiable in the IP domain. The midpoint imaging method can successfully image the reflector surfaces and the dip information even with only two shot records in a simple case.

Background/Aims: Anti-tumor necrosis factor drugs (anti-TNF) and thiopurines are important treatment options in patients with inflammatory bowel disease (IBD), including during pregnancy. However, there are limited data on the benefit/risk profile of anti-TNF and thiopurines during pregnancy in Asia. The aim of this study was to analyze pregnancy outcomes of female Japanese IBD patients treated with anti-TNF and/or thiopurines. Methods: This cross-sectional study assessed pregnancy outcomes in 72 women with IBD. Pregnancy outcomes were compared among 31 pregnancies without exposure to infliximab (IFX), adalimumab (ADA), or thiopurines; 24 pregnancies with exposure to anti-TNF treatment (23 IFX, 1 ADA); 7 pregnancies with exposure to thiopurines alone; and 10 pregnancies with exposure to both IFX and thiopurines. Results: Thirty-five of the 41 pregnancies (85.3%) that were exposed to anti-TNF treatment and/or thiopurines resulted in live births after a median gestational period of 38 weeks. Of the 35 live births, 3 involved premature deliveries; 7, low birth weight; and 1, a congenital abnormality. There were 6 spontaneous abortions in pregnancies that were exposed to anti-TNF treatment (17.7%). Pregnancy outcomes among the 4 groups were similar, except for the rate of spontaneous abortions (P =0.037). Conclusions: Exposure to anti-TNF treatment or thiopurines during pregnancy was not related to a higher incidence of adverse pregnancy outcomes in Japanese IBD patients except for spontaneous abortion.

In the Phase II investigations, the long-term hydraulic monitorings, such as groundwater pressure monitoring, tiltmeter measurements and analyses and self potential monitoring, were carried out to characterize hydrogeological structure in the hydraulically disturbed condition due to the MIU construction. The investigation results indicate the faults in/around the MIU construction site have a low or anisotropic conductivity (normal direction to fault plane: low conductivity, in-plane direction to fault plane: high conductivity). The geological mapping of the shafts and galleries revealed that a fault with altered granite was intersected by the Main shaft12). This result is consistent with the results of the characterization of hydrogeological structure using the hydraulic monitoring. It was also characterized that horizontal layer or layers in the sedimentary cover act as flow barriers as well as the faults. There is also the rock volume that is bounded by and hydrogeologically isolated by these hydraulic structures. The result of the groundwater flow analysis using the revised model based on the above investigation results indicates that the head distribution and inflow rate are significantly influenced by the hydrogeological structures modelling. Therefore it is very important to construct appropriate geological and hydrogeological models based on the investigation results. It is also important for site characterization to combine the field investigations and simulations.
