E-181 - Production Log Interpretation

5 days LOG/LPEMR
Level
Foundation
Audience
  • Production, reservoir or workover engineers, field production managers, and supervisors
Purpose
  • To provide a practical understanding of production log interpretation in vertical, deviated or horizontal wells using a dedicated software
Learning Objectives
  • To carry out a basic interpretation of PLT data using the software program Emeraude™
  • To learn the interpretation technique for horizontal wells
  • To practice on multi-probe analysis with data gathered from Multi Array Production sondes and Flow Scan Imager
Prerequisite
  • Knowledge of PLT calibrations, holdups measurements and flow-rates calculations is recommended
Ways and means
  • Hands-on sessions with use of production log interpretation software Emeraude™ of KAPPA Engineering

Basic features and software practice
  • Basic features applied to a 2-phase gas oil well example
  • Software presentation: well data, well sketch, features and layouts
  • Zones definitions: reservoirs, perforations, calibrations, inflow, calculations of rates
PL interpretation of diphasic flows
  • Handle diphasic flow in deviated well, with shut-in and production surveys
  • Practice on spinner reversals
  • Integrate PVT data and determine production rates per zone & cumulative rate
  • Apply all previous practices on field example with 3-phase flow
Horizontal wells
  • Handle data from horizontal wells logged with Flow Scan Imager & Probe Flow Caliper Sonde with 3-phase flow and shut-in & production surveys
  • Obtain average values of velocity & holdups through process of passes from flowing survey
  • Perform full PL interpretation with previous inputs
PL interpretation with multiple probes tools
  • Interpret data set from multiple probe tools in case of deviated well, with Emeraude™ software, with logs acquired with spinner array, capacitance array, resistivity arrays tools in a 3 phase flow well
  • Quality control of data
Single phase gas well
  • Interpretation of temperature log with Emeraude™ segmented and energy equation models
  • Case of apparent downflow & selected inflow performance
