“…Seam 4 in the Lower Cretaceous Gates Formation, Inner Foothills of Alberta showed gas saturation levels of 90% in the in situ reservoir conditions [53]. Unsaturated CBM reservoirs initially produce CBM only when the reservoir pressure is reduced below the critical desorption pressure [59,60]. A small degree of unsaturation can necessitate prolonging dewatering period before a large reservoir volume can reach the critical desorption pressure [57].…”

“…Therefore, unsaturated CBM reservoirs do not produce CBM at the dewatering stage and CBM initially desorbs from the internal surface of the coal matrix only after the reservoir pressure is reduced to the critical desorption pressure and goes on [59,60]. Thus, a small degree of unsaturation can necessitate widening the pressure drop to produce gas for CBM reservoirs and prolong dewatering before a large reservoir volume can reach the critical desorption pressure [57].…”

-A large number of models have been established to describe permeability variation with the depletion of reservoir pressure to date. However, no attempt has been made to draw enough attention to the difference in the effect of various factors on permeability variation in different production stages of unsaturated CoalBed Methane (CBM) reservoirs. This paper summarizes the existing and common permeability models, determines the relationship between various effects (effective stress effect, matrix shrinkage effect and Klinkenberg effect) and desorption characteristics of the recovery of unsaturated CBM reservoirs, then establishes two improved models to quantificationally describe permeability variation, and finally discusses the effects of various factors (gas saturation, cleat porosity, Poisson's ratio and shrinkage coefficient) on permeability variation. The results show that permeability variation during the recovery of unsaturated CBM reservoirs can be divided into two stages: the first one is that permeability variation is only affected by the effective stress effect, and the second is that permeability variation is affected by the combination of the effective stress effect, matrix shrinkage effect and Klinkenberg effect. In the second stage, matrix shrinkage effect and Klinkenberg effect play much more significant role than the effective stress effect, which leads to an increase in permeability with depletion of reservoir pressure. Sensitivity analysis of parameters in the improved models reveals that those parameters associated with gas saturation, such as gas content, reservoir pressure, Langmuir volume and Langmuir pressure, have a significant impact on permeability variation in the first stage, and the important parameters in the second stage are the gas content, reservoir pressure, Langmuir volume, Langmuir pressure, Poisson's ratio, Young's modulus and shrinkage coefficient during the depletion of reservoir pressure. A comparative study of the improved models indicates that the improved SD model has a greater sensitivity to various parameters than the improved PM model and the improved models describe permeability dynamic variation more exactly than the original ones.Résumé -Modèles de variation de perméabilité pour des réservoirs de gaz de houille insaturé -Un grand nombre de modèles ont été établis à ce jour pour décrire la variation de perméabilité en fonction de l'épuisement de la pression du réservoir. Toutefois, aucune tentative n'a été faite pour attirer suffisamment l'attention sur la différence d'effet des différents facteurs sur la variation de perméabilité dans différentes phases de production des réservoirs de gaz de houille insaturés (CoalBed Methane, CBM). Le présent article résume les modèles de perméabilité existants et usuels, détermine la relation entre les différents effets (effet de contrainte effective, effet du rétrécissement

“…In literature several storage media are investigated, being: deep saline aquifers; (nearly) empty oil fields, possibly with Enhanced Oil Recovery (EOR); (nearly) empty gas fields, possibly with Enhanced Gas Recovery (EGR) and deep unminable coal layers combined with Enhanced Coal Bed Methane production (ECBM) (Hamelinck et al, 2001;Van Bergen et al, 2003).…”

The Environmental Impact Assessment (EIA) and Strategic Environmental Assessment (SEA) are procedural tools which have as goal to assess and evaluate possible environmental effects of, respectively, a proposed project or policy plan. The goal of this article is to explore possible bottlenecks in applying both the EIA and SEA procedures on Carbon Capture and Storage (CCS) activities in the Netherlands, as experience is currently minimal or lacking. In this study we focus mainly on the institutional and procedural aspects of the screening and scoping phases of both procedures. This is achieved by reviewing EIA and SEA procedures for analogue projects for the three distinctive process steps of a CCS project, namely the power plant with capture, the transport and finally the underground storage of the CO 2 . Additionally, EIA and SEA or similar procedures on CCS in other countries are reviewed and the legal framework for the Dutch EIA and SEA is studied. This article shows a concise overview of the EIA and SEA procedure in the Netherlands and the relation between both procedures. Based on our findings we have constructed a conceptual taxonomy for the scope of both procedures for CCS in the Netherlands. This taxonomy conceptualizes the possible integration of assessing the environmental impacts for tiered levels of decision making. This integration might be needed for first CCS projects as decisions on the strategic (spatial planning) level are currently absent for CCS in the Netherlands. Perpendicular to such integration is the integration of linked activities in the CCS chain and their alternatives, into one procedure. We argue that it would be beneficial to combine the separate EIA procedures for CCS activities into one procedure or at least provide close linkage between them. This issue should be carefully considered by regulators, competent authorities and project initiators in an early

“…A NOVEM report estimated that about 8 Gt of CO 2 could be stored in Dutch coals (Hamelinck et al, 2000). The CO 2 storage capacity of deep coals in Alberta, Canada has been estimated to be about 20 Gt (Gunter et al, 1997).…”

Résumé -Stockage du CO 2 dans des veines de charbon non exploitables -Le mécanisme de stockage du CO 2 dans les veines de charbon (coalbeds), l'adsorption, est très différent de ceux intervenant dans les réservoirs d'hydrocarbures ou dans les aquifères, où le CO 2 occupe les pores en tant que phase distincte ou bien est dissous dans l'eau ou l'huile. Durant les 20 dernières années, le méthane issu des veines de charbon (coalbed methane ou CBM) est devenu une source importante (non conventionelle) de gaz naturel aux États-Unis. L'injection de CO 2 pour augmenter la récupération de CBM (CO 2 -ECBM) est une technologie émergente qui pourrait permettre de stocker des volumes importants de CO 2 anthropique dans les veines de charbon, tout en augmentant l'efficacité de la production de méthane.
