Estimation of the Largest Russian Oil Field Development Efficiency Using the Combination of Hydrodynamic Modeling and Horizontal Well Production Logging Methods Using Markers

Increasing the pace of oil production to achieve profitability in projects has increased significantly with the transition to the active development of deposits with low-permeable reservoirs throughout the West Siberian oil and gas province. The key to increasing production rates for objects with degraded reservoir properties is to increase the technical and technological effectiveness of the applied solutions. The purpose of the article is to evaluate the project using data obtained by the new, innovative tracer-based methods and contemporary types of well completion in well testing to increase the drainage area, flow rate and improve the operational parameters of the pressure maintenance system. Greater reservoir filtration areas in reservoirs with abnormally low permeability is achieved by using horizontal drilling and fracturing. Modern modeling tools allow for the consideration of uneven development of the horizontal shaft length. Conventional logging methods cannot provide detailed information during the operation of hydraulic fracturing stages, but marker-based methods present a proper production logging alternative, especially given their widespread development in recent years. Using the data of marker diagnostics, it is possible to adapt hydrodynamic models to specify the hydrocarbon production profiles. The present article brings to your attention sector hydrodynamic model (HDM) calculations that take into account the uneven development of depleting reserves based on marker diagnostics data. A comparison was made with HDM under the assumption of a uniform inflow into horizontal well with MFrac. The model showed several levels of inflow variability obtained through statistical data on the marker production logging of 60 wells performed at various fields.
