Guided Interpretation #9 • B09 - 12/22
Two 2D models are available for the MAPS suite (linear for the holdups and linear for the
velocities) and as indicated before, physical constraints can be added to the non linear regression:
phase absence, vertical segregation (e.g. water holdup decreasing from bottom to top),
conventional tool measurements (density, capacitance, spinner).
The job will be analyzed with the SAT measurements, using the constant calibration already
defined, and the central spinner measurements. CAT and RAT measurements will also be used.
¾
Go to ‘PL Interpretation’, ‘Information’, ‘Reference channels’ tab and define the
interpretation inputs: TEMP, QP, and DENR with pass Up1.
¾
Go to ‘PVT’ and define fluid type as saturated oil with water. Enter 903 cf/bbl for the
solution GOR, salinity = 18000 ppm, gas SG = 0.78, oil gravity = 26.3° API.
The definition of pressure, temperature inputs and PVT are required for the reconstruction of
central tools measurements during the processing.
¾
Press the ‘MPT processing’ button in the Control Panel.
¾
The settings button on the ‘Tool type’ line allows selecting the MAPS tools to be considered.
Click on it and select all tools as shown below.

¾
The 2D model is by default ‘Linear Velocity – Linear Holdups’.
¾
Select Average ‘Areal’.
¾
In Range, choose to process at ‘Interval’ with a value of 1ft. This interval value also
governs the depth spacing for the averages.
¾
Phase constraints: the choice depends on the tools selected. The logic is that a phase
constraint is offered unless an included tool gives the holdup of that phase directly. In our
case, we use all MAPS tools so the choice is none or Yo=0. We keep ‘none’ as we know that
oil is produced.
¾
Physical constraints: we select both choices to force water and gas gravity segregation.
¾
Tool constraints: choose to simulate VAILS, VACFB and DENR to check for consistency.
¾
Select passes D2 and D3 as combined passes. Note that, if you have unchecked pass
Down1 before checking passes Down2 and Down3, the SAT has been automatically
unselected in the Tool type settings (re-select it).
