“…According to the British Petroleum (BP) statistical review (2017), the energy consumption is expected to reach to the maximum level of around 3542.9 billion cubic meters in 2018 [11]. This massive increase in energy demand may be the result of increased industrial units, urbanization and population growth.…”

Climate change is one of the most challenging issues in Pakistan and has affected humans in every sphere of life. Pakistan is ranked on 8th in the world among the countries emitting Greenhouse gases (GHG). Such an extensive emission of GHG is due to the growing number of industrial units and urban centres consuming fossil fuels that emit GHG at a large scale. Mitigating the GHG emission indeed is a challenge for Pakistan. This manuscript highlights the GHG emission status and provides recommendations with suitable alternatives to mitigate the emission. Simultaneously, the study explores the impact of switching over the fuels from conventional fossil fuels to unconventional natural gas as a source of energy for domestic use, transportations and industrial sectors to mitigate the GHG emission. Natural gas is considered as green fuel due to the low carbon emission ratio as other fuels e.g. coal and oil. If Pakistan becomes successful in exploring and exploiting the indigenous untapped natural gas resources, that will eventually support in reducing the GHG emissions. This is only possible by making new natural gas reservoir discoveries. Discovering new gas reservoirs from unconventional resources is also very challenging and requires investment and modification in existing energy policies. In addition, the government should encourage the Exploration Production (EP) companies to exploit the hidden natural gas potential that will assist in both alleviating the energy deficit and reducing the GHG emission. The findings of the present study analysis have substantial implications regarding GHG mitigation, energy transition, and economic development.

The production from shale gas reservoirs has significantly increased due to technological advancements. The shale gas reservoirs are very heterogeneous and the heterogeneity has a significant effect on the quality and productivity of reservoirs. Hence, it is essential to study the behavior of such reservoirs for accurate modelling and performance prediction. To evaluate the impact of fracture parameters on shale gas reservoir productivity using CMG (Computer Modelling Group) stars simulation software was the main objective of this study. In this paper, a comprehensive analysis considering an example shale gas reservoir was conducted for production performance analysis considering uniform and non-uniform fractures configurations. Several simulations were performed by considering the multi-stage hydraulically fractured reservoir. The sensitivities conducted includes the different cases of moderate and severe heterogeneity along with variable fractures half-length, effect of changing fracture spacing, variable fracture conductivities. The simulation results showed that by increasing conductivity of fracture increases the gas production rate significantly. Moreover, cases of reservoir permeability heterogeneity were analyzed which show the significant effect on gas rate and on cumulative gas production. The results of this study can be used to improve the effectiveness in designing and developing of shale gas reservoirs and also to improve the accuracy of analyzing heterogeneous shale gas reservoir performance.

“…However, most oil and gas reservoirs are rapidly consuming (Al-Fatlawi et al 2017a, b), and natural gas is a non-renewable resource (Martin-Gil et al 2019). Shale gas, a kind of methane based, very important clean energy, is a potential energy which develops in a sustainable way (Shar et al 2018) and has long development life and rich resources, which is an ideal substitute for natural gas. It is found that China is rich in shale gas resources, and there are shale gas accumulation conditions in Junggar Basin (Pang et al 2018), Ordos Basin (Zhao et al 2016), Sichuan Basin (Zhang et al 2015), etc., which has a very broad development prospect.…”

The exploitation and exploration of shale gas is of great values to solve the energy problem. Taking the shale from Silurian Longmaxi formation in Sichuan Basin as an example, its geological characteristics and reservoir chemical reaction under the action of fracturing fluid were analyzed, and moreover, a series of data determination and fracturing fluid chemical reaction experiments were carried out. The results showed that the average total organic carbon value of shale in the study area was 4.79%, the kerogen type was type I, the ratio of aliphatic structure to aromatic structure was smaller than 1, the average R O value was 2.15%, the content of clay mineral in the mineral composition was high, the average porosity was 3.16%, and the average permeability was 0.036 × 10 3 μm 2 , which was conducive to shale gas generation; under the action of fracturing fluid, the sulfate mineral in the shale dissolved, clay mineral expanded, and the pore volume and specific surface area reduced. The results verify that the research area has shale gas mining value, and this study makes some contributions to further study the optimization of fracturing fluid and improve exploitation technology.
