MULTIPLE ARRAY PRODUCTION SUITE (MAPS)

MAPS

In deviated and horizontal wells, conventional production logging tools are often inadequate to provide a comprehensive analysis of the downhole flowing conditions. Multiple Array Production Suite (MAPS) is a landmark innovation in well logging technology, adding an entirely new dimension to production potential. It enables the user to deploy multiple sensors to build a clearer and more accurate picture of the flow regime resulting in superior reservoir management in wells ranging from slightly deviated to horizontal.

MAPS is a combination of tools that provides holdup data from Resistance Array Tool (RAT) and directional and speed of multi-phased flow from the Spinner Array Tool (SAT) measured around the wellbore.

MAPS makes it possible to provide quantitative estimates of the volumetric flow rate of each phase with a much higher degree of confidence and thus provides vital information for reservoir management.

Software

MAPS CAN PROVIDE ANSWERS FOR THESE FREQUENT QUESTIONS:

Well Loading:

 Is water falling back or cycling and hindering production?

Effectiveness of Stimulations:

Are the stages stimulated effectively for maximum mobility?

Stage Comparison:

How do some stages compare to others in the same well?

Drilling Trajectory Effects on Production:

Is the way in which the well was drilled affecting production now or in the future?

Contribution:

Where are the water, oil, and gas coming from?

Water Banking:

Is the high water holdup due to water production or banking?

Spinner Array Tool

The Spinner Array Tool (SAT) features six miniature turbines deployed on bowspring arms, enabling discrete local fluid velocities to be measured at 60 degree intervals around the wellbore and provides direct measurement of individual phase velocities.

The Resistance Array Tool (RAT) has 12 micro resistance sensors deployed on bow springs to determine the water holdup profile across the whole wellbore. Water (brine) is conductive, while oil and gas are non-conductive.

Phase segregation occurs in many wells, including those with little deviation from vertical; the lighter phases migrate to the high side of the well, the heavier phases to the low side.

The Resistance Array Tool differentiates between conductive water and hydrocarbons, which are non-conductive, and will detect very small, fast moving bubbles. This allows determination of the water holdup cross-sectional profile in wellbores of any deviation, from vertical to horizontal, and in any flow regime.
