Main principles of the improved technique for the estimation of gas reserves in low-permeability Turonian sediments

The article describes the main principles of estimating volumetric parameters of gas onshore deposits in low-permeability reservoirs of the Turonian stage that were formed as a result of the long-term study of “supra-Cenomanian” sediments at the fields of Rosneft Oil Company PJSC, in particular, at the largest Kharampurskoye oil and gas condensate field. Based on a detailed analysis of the section, the authors formulated recommendations for optimal logging suite, well testing and analysis of the core taken from highly swellable clay rocks of the Kuznetsov formation.

Very High

This study considers potential policy responses to the still very high levels of exposure to arsenic (As) caused by drinking water from shallow tubewells in rural Bangladesh. It examines a survey of 4,109 households in 76 villages of Araihazar upazila conducted two years after a national testing campaign swept through the area. The area is adjacent to the region where a long-term study was initiated in 2000 and where households are periodically reminded of health risks associated with well-water elevated in As. Results confirm that testing spurs switching away from unsafe wells, although the 27% fraction who switched was only about half of that in the long-term study area. By village, the fraction of households that switched varied with the availability of safe wells and the distance from the long-term study area. Lacking follow-up testing, two years only after the campaign 21% of households did not know the status of their well and 21% of households with an unsafe well that switched did so to an untested well. Well testing is again urgently needed in Bangladesh and should be paired with better ways to raise awareness and the installation of additional deep community wells.

The article explores the features of well test interpretation results of oil and gas horizontal wells in the southern Iraqi fields. The author pays attention to the deconvolution method during processing the results of studying horizontal wells. The conclusion is made to determine the boun-daries of the drainage area of the wells on the need for a long-term study of horizontal wells.
