The influence of the rocks material composition on the reservoir properties of the reservoir

Abstract

High oil reserves characterize most fields in Western Siberia. However, along with this, zones of the productive formation that are poorly involved in development and production wells, in which products with a high proportion of water are produced, are distinguished within limits. For understanding the causes of this problem, it is important to consider the material composition of the reservoirs. In particular, it is necessary to consider the clay content, which is associated with the reservoir properties of rocks, hydrophilicity, hydrophobicity and, accordingly, with wettability. The article examined and analyzed a representative sample of core study of two wells in the Gubkinsky oil and gas region, which suggested the possible reasons for the lack of oil reserves.

Use of geotechnical monitoring data in the design of the Serginsky field development

“…At the first stage, the geological and physical features of the reservoirs of the Serginsky field were considered; at the second stage, the results of substantiation were adjusted with regard to technological and economic factors. In addition, when commissioning of production facilities was substantiated, the experience of deposit exploitation accumulated during the period of pilot development of the field was taken into account [3,4].…”

Laboratory studies on the use of surfactant compositions to solve resource extraction problems

“…The experience of long-term development of fields shows that as oil reserves are depleted, it is necessary to make sound technological decisions based on the study of oil recovery processes in laboratory and field conditions [1][2][3][4][5][6][7][8][9][10].…”

Reassessment of the potential of oil reserves in thin-layered “hazel grouse” type reservoirs

“…The modern structure of the resource base of oil producing enterprises in the West Siberian oil and gas province has forced oil engineers to extract hard-to-recover oil reserves associated with lowpermeability reservoirs [1][2][3][4][5][6]. Involvement of unconventional reservoirs creates the need for adaptaing available technologies to specific cases and searching for economically optimal solutions [7][8][9]. The formation AV1 (1-2) is a striking example of an anisotropic, thin-layered highly-clayey reservoir, composed of sandstone of the "hazel-grouse" type, mixed-grained siltstone and clay interlayers.…”
