Problems solved by technology

In addition to the limitations inherent in the interpretation of production fluids, including tracers, fracturing fluids, and / or hydrocarbons, the second technique is limited in the amount of tracers that can be placed in the interval of a single well and in the production fluids. There are limitations in the detection of tracers

Abstract

Various methods and well systems are provided for characterizing hydraulically fractured hydrocarbon-bearing formations traversed by wells separated into well intervals. The method and well system analyze the surface flow properties of fluids flowing from the well (e.g., using a multiphase flow meter) in order to characterize the local formation for one or more intervals of the well (or other portion) characteristic.

Description

Background technique [0001] Well completions to produce hydrocarbons stored in tight reservoirs are often complex and costly to install and maintain. Recognizing these complexities and costs, there has been an increased emphasis on the efficiencies associated with these completions and maintenance over the life of the well. [0002] It is common for wells producing hydrocarbons stored in tight reservoirs to be partitioned into intervals (also called segments or zones) spaced along the length of the well. Short sections of non-porous production tubing (eg, liner or sleeve sections) may be located between these spaces to support the isolation of the respective spaces. During well completions, hydraulic fracturing operations may be performed in intervals of wells. Hydraulic fracturing operations introduce high-pressure fracturing fluids through the frac casing or liner / sleeve perforations into adjacent formations, which cause the fracture of the adjacent formation's reservoir r...
