CALIBRATION & INTERPRETATION
When you engage our services for a new project, our proprietary analysis techniques become even more enhanced when we are provided data for calibration. The data for calibration should include open hole log data, fracking intervals and production history of the wells. The results of rock eval pyrolysis analysis are also useful.
Calibration process information needed:
-Wells with production close to minimum and maximum (calibration and testing wells)
-Same (or similar) fracking technique for all calibration and testing wells preferable
-Five to ten calibration wells available if possible
-Log data & production history
-Measured Depth (MD) for each perforation interval
-MD for tops of all geological formations in the intervals of interest
-A map that shows well positions (coordinates are not required)
Data from wells with selective fracking are ideal for calibration. If unavailable, we use wells with 10 to 12 fracking stages and apply the method of successive approximations.
Because of the nature of the technology, more calibration data result in a more accurate interpretation. Each new well contributes to the tuning of the model; and, accordingly each subsequent well is processed more accurately than the previous.
The process of calibration and well interpretation takes one to two weeks for the first few wells. From that point, the interpretation of each well is approximately one day. Interpretation of the calibration wells, and one "test" well, are performed at no charge.
To utilize Amros technology, the MINIMUM log data required includes gamma ray, resistivity logs, neutron and density porosity logs.
Optional data includes; Spontaneous Potential (SP), Photoelectric (PE) Index, Sonic Porosity and Caliper Log.
The production profile we provide you will show the production rate, in bbl/day, at each depth interval. This is much more meaningful than typical "pay flags". In addition, the technology makes it possible to calculate brittleness or breakdown pressure that allows you to more accurately estimate the cost of hydraulic fracturing. The resulting data make it easier to determine the economic feasibility of fracking each zone. Consequently, instead of fracking 10 - 12 stages for most wells in the Permian basin, it would be sufficient to frack just 5 – 6 stages without decreasing production. In fact, by precisely targeting the best intervals, production will most likely be significantly increased.
