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 carbonate reservoir formation evaluation is to determine the reservoir storage capacity, flow capacity, mineralogy and mechanical rock properties while honoring physical data measurements. Carbonate reservoirs often exhibit variable porosity and saturation exponents making it difficult to evaluate and to quantify the hydrocarbons in place using wireline logs. Key well studies that incorporate conventional core analysis and wireline log analysis assist in determining these factors for application to offsetting wells without core available. The results of this analysis are instrumental in pay zone identification and quantification, stimulation treatment design and reservoir modeling. The goal of carbonate reservoir evaluation is to use the core analysis data to help develop models to determine the porosity types, vuggy or grainstone, variable saturation and porosity exponents, m and n using all the tools available, in order to obtain meaningful estimates of hydrocarbons in place. This calibrated model can then be used for all the wells in a field for enhanced recovery studies, pay identification in step out wells or “problem” well evaluations.   Benefits of the Carbonate Reservoir Formation Evaluation Log 

1. Resource Assessment: Define pay thickness, original hydrocarbons in place and water avoidance when making completion decisions
2. Capture all the available core data in a calibrated petrophysical model that can be used in future evaluations
3. Carbonate Resource Estimate: Determine the reservoir properties, mechanical rock properties and resource potential for use in future modeling
4. Frac Model Inputs: Derive the inputs necessary for importing into the frac model of your choice

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. The CBM/CSM Evaluation log is calibrated using locally available core data. Both coals and the surrounding shales or sands are also included for a full resource potential. 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, stimulation treatment design and reservoir modeling.   Benefits of the CBM Analysis Log:

1. CBM Resource Assessment: Define coal thickness, tons/acre and gas content
2. Sand and Shale Resource Estimate: Determine the reservoir properties and resource potential of the shales or sands between the coals for additional gas resource or to identify the source of unwanted water production
3. Frac Model Inputs: Derive the inputs necessary for importing into the frac model of your choice

The results of this analysis are instrumental in the pay zone identification and quantification, stimulation treatment design and reservoir modeling. When evaluating the tight sand intervals, instead of maxing out the “shale” volume as is typical for a clean formation analysis, an attempt is made to determine the clay volume within these high Gamma Ray intervals. The fluid contents of the free porosity can be evaluated and used for resource evaluations. The figures above show the volumetric and rock properties segments of the Shale Evaluation Analysis log.   Benefits of the Tight Sand Evaluation Log 

1. Resource Assessment: Define pay thickness, original hydrocarbons in place and which sands to combine together in frac stage
2. Capture all the available core data in a calibrated petrophysical model
3. Sand Resource Estimate: Determine the reservoir properties, mechanical rock properties and resource potential of the shales and potential sands between the shales for additional gas resource or to identify the source of unwanted water production

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 model is broken into two components: (1) the traditional sand and carbonate reservoirs and (2) the non-traditional shale intervals. 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, stimulation treatment design and reservoir modeling. When evaluating the non-traditional “shale” intervals, instead of maxing out the “shale” volume as is typical for a clean formation analysis, an attempt is made to determine the clay volume within these high Gamma Ray intervals. The fluid contents of the free porosity can be evaluated and used for resource evaluations. The figures above show the volumetric and rock properties segments of the Shale Evaluation Analysis log.   Benefits of the SHALE Evaluation Log

1. Organic Shale Resource Assessment: Define shale thickness, average bulk density, gas content, original hydrocarbons in place, and where to land the lateral for horizontal wells
2. Capture all the available core data in a calibrated petrophysical model
3. Sand and Shale Resource Estimate: Determine the reservoir properties, mechanical rock properties and resource potential of the shales and potential sands between the shales for additional gas resource or to identify the source of unwanted water production
