MRT SUMMARY

Multiwell Retrospective Testing (MRT) is a data processing technique which is based on automatic matching of production rates and bottom hole pressure readings (including ESP pressure gauges) in a tested well and its neighbours to provide

  • reconstruction of formation pressure and productivity index history
  • quantify the cumulative and current cross-well interference
  • assess transmissibility of the cross-well intervals
  • predict formation pressure dynamics in various production scenarios

Unlike traditional single-well pressure transient analysis (PTA) or rate transient analysis (RTA) the MRT study provides opportunity to assess reservoir properties through the well data which severely affected by cross-well interference, which is normally the case in practical applications.

MRT analysis is performed over the existing historical data records and does not require additional data acquisition.

The MRT engine is based on multi-well pressure deconvolution which is briefly presented below in MRT TECHNOLOGY section.

The MRT workflow is facilitated by the PolyGon software which provides data processing, numerical modelling and data interpretation.

APPLICATIONS
Production Enhancement
  • Locating priority zones for the new wells and side-tracks
  • Selecting priority candidates for workovers (water shut-off, stimulation, fracturing)
  • Optimize production targets
  • Identifying the best candidates for converting to injection
Reservoir Study
  • Assessing the length and orientation of hydraulic fractures
  • Identifying the presence of spontaneous fractures
  • Assessing fault conductivity
  • Localizing the barriers and pinch outs
  • Calibrating shale breaks
  • Quantification of the cross-well interference
  • Quantification of reservoir properties in cross-well interval
  • Quantification of reservoir properties in near-well area
  • Reconstructing the history of formation pressure and productivity index
  • Adjusting the random mistakes in flow rate history records
ADVANTAGES
  • No field operations and no production deferment
  • Reconstruction of formation pressure and productivity index history
  • Reconstruction of cross-well interference history
  • Immunity to random mistakes in rate history records
  • Immunity to random mistakes in rate history records
