The ability to dynamically observe temperature and pressure at the production zone has provided valuable information. The most common, and most significant finding is that bottom hole temperature is nearly always lowered during production. In a well that had been in production for more than a year, we observed that the bottom hole temperature was 8 °C below the driller’s reported value. That has been typical for all wells but two, one a water-out horizontal and the other at the edge of a steam flood, with the temperature before heat is applied being 4 to 9 °C below expected values. When the MxL system is applied to an existing well, that has reserves and adequate drive pressure, increased production can usually be realized.

The following case histories show the potential of the system in varied circumstances.
Case History 1
A high water cut horizontal in a block with slowly declining production. A probe style MxL Induction Heater was utilized to slow the rate of decline and decrease the water cut.
HORIZONTAL SUFFIELD BLOCK
Case History 2
A waxy well in the Alsace France region. A resistance style heater and multiple squeezes showed potential for increased production, however, longevity of the squeezes and in particular the resistance style heaters was limited. A MxL Induction heater was installed in 2005 and upgraded in 2011. The well which had been assessed to last no more than 2 years before heating is still producing as of late 2014.

Case History 3
In 2008 our system was utilized in Methane Hydrate Research. Proving the flexibility of the MxL Induction Heating System we were able to assist in the first sustained recovery and mitigate re-hydration during production.

Case History 4
A high free gas and water cut heavy oil well with declining production after remedial work-overs. Our first in a limestone rubble formation.
