The Impact

Shale gas holds great promise for a countrys economic development and energy independence, but also holds potential perils for the natural resources and the communities. Following the shale gas revolution in the US, China is in full swing to deploy its strategic plan for the shale gas. The Ministry of Land and Resources (MLR) has announced the legal status of shale gas as the 172th independent mining resource, and hosted two rounds of bidding for the commercial development of 23 shale gas blocks. The shale gas revolution seems to may happen in China as well. However, some great challenges exist during the shale gas extraction. One is the impact on water resources for shale gas production, unlike the US, water shortage has been a severe problem in China, hindering its economic development. The other one is that shale gas operations may induce environmental problems, such as accidental spills of flowback water, which contains toxic substances. Spills could have long-term cumulative effects on ecosystems, as with oil spills. This paper highlighted water resources challenges and policy vacuum facing in China. Although the U.S. shale gas experience can assist in identifying some potential issues that Chinese regulators and operators may encounter, policy decision on this issue should be based on risk assessment and regulation studies. For China, there is a long way to lay the groundwork for the shale gas revolution.

The Impact

It has been said that the development of a shale gas industry could be a ‘game changer’ for South Africa. Proponents of shale gas tend to emphasise the benefits, whilst opponents emphasise the environmental costs. This paper is an attempt to inform the policy debate by highlighting both the potential economic benefits and environmental costs. To date, the Econometrix report (published in 2012) provides the only estimate of the economic impacts that may emanate from developing the Karoo’s shale gas. The report uses a Keynesian multiplier model to estimate the impacts. The analysis performed in this paper estimates the economic impacts using a Computable General Equilibrium (CGE) modelling approach, and the results are compared to the findings of the Econometrix report. In doing so, this paper provides an expanded view of the potential economic impact. Accordingly, this paper provides a number of findings on the estimated economic impact of shale gas extraction – based on the application of an economy-wide impact modelling methodology – which should be of interest to both opponents and proponents of the shale gas industry. By including all possible results, such as a boost in public sector jobs and an analysis of the impact on consumer prices and jobs in other sectors, this paper expands the current understanding of the likely impact of shale gas extraction in the Karoo of South Africa.

Dense unconventional shale gas extraction activities have occurred in Appalachian Ohio since 2010 and they have caused various landcover changes and forest fragmentation issues. This research investigated the most recent boom of unconventional shale gas extraction activities and their impacts on the landcover changes and forest structural changes in the Muskingum River Watershed in Appalachian Ohio. Triple-temporal high-resolution natural-color aerial images from 2006 to 2017 and a group of ancillary geographic information system (GIS) data were first used to digitize the landcover changes due to the recent boom of these unconventional shale gas extraction activities. Geographic object-based image analysis (GEOBIA) was then employed to form forest patches as image objects and to accurately quantify the forest connectivity. Lastly, the initial and updated forest image objects were used to quantify the loss of core forest as the two-dimensional (2D) forest structural changes, and initial and updated canopy height models (CHMs) derived from airborne light detection and ranging (LiDAR) point clouds were used to quantify the loss of forest volume as three-dimensional (3D) forest structural changes. The results indicate a consistent format but uneven spatiotemporal development of these unconventional shale gas extraction activities. Dense unconventional shale gas extraction activities formed two apparent hotspots. Two-thirds of the well pad facilities and half of the pipeline right-of-way (ROW) corridors were constructed during the raising phase of the boom. At the end of the boom, significant forest fragmentation already occurred in both hotspots of these active unconventional shale gas extraction activities, and the areal loss of core forest reached up to 14.60% in the densest concentrated regions of these activities. These results call for attention to the ecological studies targeted on the forest fragmentation in the Muskingum River Watershed and the broader Appalachian Ohio regions.

Shale gas is one of the primary types of unconventional reservoirs to be exploited in search for long-lasting resources. Production from shale gas reservoirs requires horizontal drilling with hydraulic fracturing to achieve the most economic production. However, plenty of parameters (e.g., fracture conductivity, fracture spacing, half-length, matrix permeability, and porosity,etc) have high uncertainty that may cause unexpected high cost. Therefore, to develop an efficient and practical method for quantifying uncertainty and optimizing shale-gas production is highly desirable. This paper focuses on analyzing the main factors during gas production, including petro-physical parameters, hydraulic fracture parameters, and work conditions on shale-gas production performances. Firstly, numerous key parameters of shale-gas production from the fourteen best-known shale gas reservoirs in the United States are selected through the correlation analysis. Secondly, a grey relational grade method is used to quantitatively estimate the potential of developing target shale gas reservoirs as well as the impact ranking of these factors. Analyses on production data of many shale-gas reservoirs indicate that the recovery efficiencies are highly correlated with the major parameters predicted by the new method. Among all main factors, the impact ranking of major factors, from more important to less important, is matrix permeability, fracture conductivity, fracture density of hydraulic fracturing, reservoir pressure, total organic content (TOC), fracture half-length, adsorbed gas, reservoir thickness, reservoir depth, and clay content. This work can provide significant insights into quantifying the evaluation of the development potential of shale gas reservoirs, the influence degree of main factors, and optimization of shale gas production.
