Resource in Place Services   

The approach to formation evaluation used by Stimulation Petrophysics Consulting is a structured methodology incorporating all the wireline log data (open hole and cased hole), mud logging, drilling and core evaluation that is provided or available into a single interpretation. For display purposes, this petrophysical model is displayed in three sections: (1) the measured log data that goes into the model, (2) Mineralogy and volumetric analysis with resource in place calculations and (3) Mechanical rock properties. The main objective of this evaluation is to determine the reservoir storage capacity, flow capacity, mineralogy and mechanical rock properties while honoring physical data measurements. The results of this analysis are instrumental in the pay zone identification and quantification, stimulation treatment design and reservoir modeling.

Benefits of the Resource in Place Services  

  1. Quantify hydrocarbons in place for economic completion decisions
  2. Use in resource values in modeling recovery factor and drainage area
  3. Map hydrocarbons in place to high-grade future drilling, help design water flood or exploration

The resource assessment of each evaluation is typically found in the middle of a formation evaluation log. In this example, the gross pay and net pay thickness appear the tracks just to the right of the depth track, the water saturation and average porosity numbers in the Saturation and Volumetric tracks are the average of the data meeting the net pay criteria. The hydrocarbon pore volume is in the HPV track. The original hydrocarbons in place are reported in terms of oil in place, gas in place and equivalent oil in place. The units of hydrocarbons are in million barrels of oil or oil equivalent and billion cubic feet of gas per section or 640 acres. The oil formation volume factor and gas volume factor and gas-oil-ratio are estimated using standard reservoir engineering models.
