fracture system in carbonate reservoirs is very complex. understanding the features of fractures such as dip, strike and the other parameters can help to distinguish the behaviour of reservoir in any exploration and production plan. image log is the best way to investigate feature planes like fracture and bedding. image log in one of drilled well #10x393 of bangestan reservoir in gachsaran oilf...

In this paper, we deal with hypothesis testing for unknown parameters. A new method is proposed based on a combination of the computational approach test and maximum likelihood estimation (CAT-MLE), introduced by [7]. The CAT-MLE does not require any knowledge of the sampling distribution. It depends heavily on numerical computational and Monte-Carlo simulation study. To illustrate the methodol...

Realizing the decoupling development between economic expansion and carbon dioxide emissions of transport sector is great importance if Yellow River basin to achieve green low-carbon development. In this paper, we adopt Tapio index examine relationship within in basin, then introduce standard deviational ellipse dynamically analyze spatial heterogeneity growth at provincial level. Furthermore, ...

Abstract The CO 2 emissions trend and their reduction potential in the Nigerian manufacturing sector from 2010 to 2020 were studied. Logarithmic Mean Divisia Index was applied decompose change into pre-set factors: carbon intensity effects, firm energy cost structure asset-turnover effect, asset-to-equity equity-funded production effect productive capacity utilization. results show that increas...

Analyzing the evolution law of carbon emissions is particularly important for designation policies on energy conservation and emission reduction. Based regional division China, this paper uses a spatial panel model to find causes differences in emission, non-parametric model, logarithmic mean Divisia index (LMDI) extended STIRPAT analyze relevant influencing factors detail. From studies paper, ...

Guangdong Province, as one of China’s fast-developing regions, an important manufacturing base, and the national first round low-carbon pilots, still faces many challenges in controlling its total energy consumption. Coal dominates Guangdong’s consumption remains major source CO2. Previous research on factors influencing has lacked a systematic analysis both from supply side (factors related to...

Renewable energy consumption (REC) has an important significance in mitigating CO2 emissions. However, currently, few scientists have analyzed the underlying impact of REC from a global geographic perspective. Thus, here, we divide world into seven regions to study this during period 1971–2016 using logarithmic mean Divisia index (LMDI). These were East Asia and Pacific (EAP), Europe Central (E...
