Abstract The active building of HW with MSHF use for ensuring their effective development in low-permeability reservoirs, but there are certain difficulties with getting completely information for making the right decisions during control of development. As part of the work performed, the main uncertainties and the further application of research results for estimates the profile of horizontal well (HW) with multi-stage hydraulic fracturing (MSHF) for planning the necessary geological and technical actions based on more than 20 operations at the South Priobskoye field are shown. The following field geophysical tests were executed in wells: PLT with Y-tool and CT + spectral noise logging module;PLT during compression with CT + multi-sensor flow meter;PLT with a well tractor;tracer studies (proppant, frac sleeves);thermometry with using fiber-optic system in injection and production wells.

Low Permeability Reservoirs

Horizontal well and large-scale fracturing are revolutionary technologies in petroleum industry. The technologies bring obvious economic benefits to exploiting unconventional oil and gas reservoirs with low permeability, ultra-low permeability and shale gas. With the increasingly extensive application of these technologies, other correlated technologies have also gained great development. However, low-permeability reservoirs exhibit complicated features and horizontal well fractures have complex shape. The existing methods for the productivity prediction of fractured horizontal well in low-permeability reservoirs rarely consider the influencing factors in a comprehensive manner. In this paper, a horizontal well seepage model of casing fracturing completion was established according to the superposition principle of low-permeability reservoir and the relationship between potential and pressure, by which model the seepage characteristics of low-permeability reservoirs could be fully described. Based on the established new seepage model, a new targeted model with coupling seepage and wellbore flow was established for the productivity prediction of low-permeability fractured horizontal well. Finally, the new targeted model was verified through field experiment. The experimental results confirmed the reliability of productivity prediction by the proposed model. Sensitivity analysis was then performed on the parameters in the proposed model.
