Evaluation and creation of the fracture network model scope of application

Abstract

Background. To optimize the development of heterogeneous reservoirs, a number of previously developed methodologies are used, including the methodology for constructing a volumetric fracture grid model by V.D. Viktorin (MOST). Summarize of previously works results showed the absence of a formalized area of MOST application and, as a result, the possibility of recommending its application in production for actually development objects. In order to form such an area, a generalization of geological and industrial information and previously conducted studies was performed. An assessment of a new unique object in the Republic of Iraq Mishrif was carried out.
Aim. The purpose of the research was to determine the boundary conditions for the application of the volumetric fracture grid model method as a way of taking into account the complex heterogeneous structure of carbonate reservoirs, as well as to determine the possibility of using this method for the highly productive Mishrif object of the Republic of Iraq.
Materials and methods. The research methods were the analysis of the results of previously works, determination of the researching objects parameters intervals, MOST by V.D. Viktorin. The initial data were the reports of previously completed R&D for the Perm Territory objects, geological and industrial information on the results of the Mishrif object studies (Republic of Iraq).
Results. The work considers widely used approaches to accounting for fracturing, characterizes the capabilities of the proposed method, builds a model using the MOST methodology (Viktorina V.D.) for a previously unexplored object Mishrif of the Republic of Iraq, forms (without Mishrif) and expands (supplemented with the Mishrif) the scope of the method. The research results shows possibility to recommend the creation of methodological approaches to the use of a volumetric fracture mesh model (MOST) for geological and hydrodynamic models of objects included in the scope of the method.
Conclusions. Based on the research results, the boundary conditions for the application of MOST are determined taking into account previously completed work, the possibility of using MOST for the highly productive Mishrif object of the Republic of Iraq is confirmedthe scope of this method is expanded.
