Embodiment Construction

[0018]At the outset, it should be noted that in the development of any such actual embodiment, numerous implementation—specific decisions must be made to achieve the developer's specific goals, such as compliance with system related and business related constraints, which will vary from one implementation to another. Moreover, it will be appreciated that such a development effort might be complex and time consuming but would nevertheless be a routine undertaking for those of ordinary skill in the art having the benefit of this disclosure.

[0019]Some embodiments described herein provide methods to maximize the efficiency of the reservoir production data analysis by using the allocation of the commingled production data in a commingled multilayer hydraulically fractured reservoir with multi-rate production log information.

[0020]An additional step in the production data allocation using modern multi-rate production logs to establish the inflow performance behaviour of each of the comple...

Abstract

Optimizing reservoir production in a commingled hydraulically fractured reservoir by allocating commingled system production data to each of the individual completed intervals in the system, calculating the reservoir and fracture properties for each completed reservoir layer, and recalibrating the commingled and individual layer production data by accounting for the individual completed interval reservoir and fracture properties.

Description

[0001]Embodiments relate to methods for optimizing the overall reservoir production. In particular, the the use of reservoir and fracture properties in the analysis of production performance of multilayer commingled reservoirs.BACKGROUND ART[0002]The statements in this section merely provide background information related to the present disclosure and may not constitute prior art. Reservoir characterization and well completion efficiency evaluation in a multilayer commingled system and well production performance data and periodic production log measurements is a very important task. Commingled well production data from a system with a number of different layers with varying reservoir and well completion properties should not in general be evaluated using an equivalent single layer reservoir analog. The results of such an analysis for determining estimates of the reservoir properties and completion efficiencies of each of the individual reservoir layers in this case will be very ina...
