Considerable attention has been directed to the Devonian Horn River Formation in western Canada with respect geochemical evaluation of gas-generation and storage potential. Because organic analyses are not always useful for characterizing type amount original matter, we surmise kerogen hydrogen index (HIo) subsequently estimate a reliable total carbon (TOCo) based on combination inorganic data. Productivity (SiO2 Ba) terrestrial input (Al2O3, Hf, Nb, Zr) proxies used types, which suggest...
To evaluate the effects of repeated steroid injection at subacromial bursa with different interval for patient periarticular shoulder disorder.Group A (n=10) received only on their first visit, group C visit and one week later, B two weeks later. All injections were done a combination 40 mg (1.0 mL) triamcinolone 5.0 mL 0.5% lidocaine (6 total). We examined active range motion (AROM) joint, visual analogue scale (VAS), disability questionnaire (SDQ) baseline 1, 2, 4 after initial...
The Late Devonian Besa River Formation is an organic-rich shale sequence in Liard Basin, northeastern British Columbia, Canada, with significant natural gas reserves. High-resolution elemental geochemistry of three long continuous cored intervals the was used to better understand paleodepositional environment this thick marine shale. studied core were divided into five chemostratigraphic units based on organic and inorganic geochemical proxies. highest total carbon (TOC) content (up 13 wt.%)...
The estimation of the hydrocarbon generation potential shales in unconventional and conventional resources depends on an accurate original total organic carbon (TOCo) content hydrogen index (HIo). TOCo is partially lost during thermal alteration whereas Mo/Al hardly altered, suggesting that a linear correlation between them immature can be used to estimate mature shales. However, this method not applicable when have different kerogen types. Herein, refined calculate for using two major...
A comprehensive estimation of shale generation/storage capacity (original generative organic carbon (GOCo)) and hydraulic fracturing characteristics (brittleness index (BI)) was conducted in the Upper Devonian sequence Liard Basin.GOCo calculated from fraction type II kerogen inferred biogenic silica concentrations.BI estimated mechanical properties well-log data.Without data, BI converted relative contribution detrital concentrations.Based on GOCo BI, sequences were divided into four...
The geological disposal of high-level radioactive waste (HLW) involves permanently isolating the wastes in stable formations deep underground.Mudstone (siltstone and claystone) containing abundant clay minerals is proposed as a host rock for HLW because have low permeability high ion sorption/exchange capacity.Despite widespread occurrence sedimentary basins Korea, there lack evaluation mudstone rocks disposal.In this study, we utilized JBH-1 borehole (7-754 m) obtained from Jinju Formation...
The Besa River Formation mainly comprises argillaceous sediments, and the upper shale bed of has been considered as a prospective gas reservoir. maturity quantity organic matter found in source rock are factors for evaluating resource value. Original hydrogen index (HIo) total carbon (TOCo) properties to estimate generated volume reservoirs. Generally, TOCo HIo determined via geochemical analysis calculated from well-log data like density, sonic data, resistivity. In this study, these were...
This paper compares assessment methodologies for shale resources to understand the amount of resources, which are estimated from various organizations. The ARI and BGS methods, a typical bottom-up approach, estimate gas oil by volumetrics using fundamental geology engineering data. However, it introduces subjective success factors recovery factor convert originally in-place into risked technically recoverable resources. On other hand, USGS method adapts top-down approach. Rather than...
셰일층의 열적 성숙도는 다양한 기법으로 평가 가능하나 셰일층에 잔류하는 유기물 특성에 따라 정확도가 달라지기 때문에 성숙도 시 주의가 요구된다. Horn River 분지의 과성숙한 데본기 셰일층은 케로젠의 함량이 매우 낮고 비트리나이트가 부재하여 일반적으로 사용되는 비트리나이트 반사도와 Rock-Eval 열분석 기법을 통해 성숙도를 평가하기 어렵다. 다량 포함된 고형 비투멘(solid bitumen)의 반사도는 평가의 대안으로 사용되어 왔으나 이외의 요인에 의해 영향을 받는 단점이 있다. 비투멘 반사도에서 변환한 유기화합물 지시자(MPI-1)로부터 변환된 유사하다. 따라서 이 연구에서는 반사도를 분지 데본기셰일층의 지시자로 활용하였다. 평균 1.9%로 가스 생성단계에 도달하였음을 지시한다. 총유기탄소(total organic carbon, TOC)의 함량은 1.5-6.8(평균: 3.8) wt%로 높은 값을 보이며 TOC에 잔류 유기탄소(residual RC)의 비율이 90%...
