Vertical Two-Phase Flow Systems and Interpretation of the Flowmeter and the Gradiomanometer Production Logs
Abstract/Contents
- Abstract
- Production Logging has become a very important tool of reservoir and production engineers as a means of identifying actual reservoir performance, evaluating completion techniques, and diagnosing well behavior. However, a basic problem i n production log interpretation is to reasonably estimate the slip velocity; that is, the rate at which one phase rises relative to the other phase.The discussion which follows is primarily concerned with the two-phase flow of oil and water. Extensive experimental work has been carried out since 1950 with many gas-liquid systems, but only a few with liquid-liquid systems. Much of the analysis of oil-water systems is based on observed gas-water behavior.This report is divided into two sections. First, we will examine the physical phenomena occurring in a two-phase system and identify the fundamental relationships and flow patterns which exist . I n particular, slip velocity will be closely studied. The work of Nicolas et, al, (1972) (10) on measurement of multi-phase fluid flow will be investigated and extended t o another correlation of slip velocity. We should then have some qualitative feel for the accuracy of slip velocity estimation. The second half of the report deals with the mechanics of actual log interpretation. After reviewing the logging tools and their capabilities, we will develop the expressions relating total flow rate,holdup, and slip velocity to the oil and water production from each zone of entry. Finally , a computer program is presented which will perform the basic calculations after the interpreter has analyzed the logs.
