Abstract Acid fracturing technique is widely applied to stimulate the productivity of carbonate reservoirs. The acid-fracture conductivity is created by non-uniform acid etching on fracture surfaces. Heterogeneous mineral distribution of carbonate reservoirs can lead to non-uniform acid etching during acid fracturing treatments. In addition, the non-uniform acid etching can be enhanced by the viscous fingering mechanism. For low-perm carbonate reservoirs, by multi-stage alternating injection of a low-viscosity acid and a high-viscosity polymer pad fluid during acid fracturing, the acid tends to form viscous fingers and etch fracture surfaces non-uniformly. To accurately predict the acid-fracture conductivity, this paper developed a 3D acid fracturing model to compute the rough acid fracture geometry induced by multi-stage alternating injection of pad and acid fluids. Based on the developed numerical simulator, we investigated the effects of viscous fingering, perforation design and stage period on the acid etching process. Compared with single-stage acid injection, multi-stage alternating injection of pad and acid fluids leads to narrower and longer acid-etched channels.

Abstract The authors argue that cross-border territories require not only an integrated approach to development, but also a form of cross-border governance that is democratic and pursues a multi-stage strategy in order to ensure accountability towards citizens and socio-economic actors and make certain that they are acknowledged and receive support at a regional and national level. At present, relevant statistical indices are lacking for most cross-border territories. Such indices are essential, however, for establishing a shared body of regional knowledge as a basis for developing joint policies and activities. Shared border areas presuppose that development takes place on both sides in order to overcome the negative effects of borders, to fully exploit the potential arising from the development of projects, and to address the needs of the inhabitants. This article examines the part played by spatial information in the planning of cross-border areas. It examines the concept of “cross-border territory”, shows the diverse criteria applied in European regional planning as exemplified in the border region of France and Luxemburg, and considers which tools are available—from the standpoint of multi-level governance—for this purpose. Ultimately, it is a question of addressing the needs, challenges and potential offered by spatial information in a cross-border context.

Rural development is the integrated approach to food production as well as physical, social and institutional infrastructural provisions with an ultimate goal of bringing about both quantitative and qualitative changes which result in improved living standard of the rural population. The study was conducted to investigate gender difference of rural dwellers’ involvement in rural development projects in Atakunmosa-west Local Government area of Osun State. It also described the demographic characteristics of the respondents, identified different rural developmental projects undergone by the respondents, showed the problems associated with their involvement and determined the men and women perceived benefits of their involvement. Data were collected with the aid of well-structured questionnaire and were administered to 60 males and 60 females in 6 communities. A multi stage random sampling technique was employed in the selection of respondents and data analysis was by the use of SPSS. Some of the findings revealed that men were well involved and women were poorly involved in development projects. Majority of respondents were Christians, were not youths and married. All the respondents encountered one problem or the other during their involvement in rural developmental projects and at the same time perceived many benefits from their involvement. It was recommended among others, that women should be encouraged to be actively involved in physical development activities by giving them adequate recognition and attention so that they can have that sense of belonging. Government and non-governmental organization should introduce more gender responsive projects to rural areas, in order to ensure active and equal involvement of both men and women.
