NIOBRARA- POWDER RIVER BASIN Regional Field Study

Field Study Introduction

NUTECH has combined its expertise with the emerging interest in North American shale plays in order to develop the most detailed regional field studies available to the E&P industry. These studies have been developed through NUTECH’s experience and analysis of several thousand wells with core and production data.

Each of NUTECH ’s studies provides insight into the connectivity across the area by simulating geological and petrophysical property distributions. The results confirm the stratigraphic variability as well as identify and quantify hydrocarbon columns per well and across the study area.

NUTECH ’s management team will provide geological-based input to assist you in decision making on each well, including working closely with your technical personnel in connection with well evaluations and listings.

Field Study Deliverables

1) Individual NULOOK Shale Analysis of each well in the study. Includes core calibrated calculations of permeability, effective porosity, water saturation, TOC, and lithology identification. Presented in pdf and tif format

2) Individual NuList Engineering Summary providing reservoir parameters in tabular form and additional calculations of Net Permeability, Hydrocarbon Pore Volume, and Free and Adsorbed GIP (BCF/sec) or OIP(MMBO/sec). Presented in .xls format

3) .las file for each well including the original open hole data going into the petrophysical model, and the curves

generated through NULOOK analysis


A sampling of wells taken from the regional study has been selected for NUSTIM horizontal completion optimization. NUSTIM evaluation builds on the Petrophysical & GeoTextural analysis by incorporating completion & economic data to deliver an optimized completion design for the reservoir of interest. Using a 30 scenario frac simulation model, NUSTIM will investigate various completion parameters including lateral landing point, rate, size, concentration, fluid, prop, and cluster spacing in the horizontal. Comparisons of created frac geometry, predicted production & decline, and ultimately Net Present Value will provide the client with an optimized completion design for the reservoir in this area. A recommended landing lateral target & pump schedule for the selected completion design is included. Deliverables for each of the NUSTIM wells will include pdf of the NUSTIM report & also an Executive Summary in PowerPoint format that steps through the NUSTIM process and results.

Net Present Value Optimization


1. 3D Structural Model using well picks for the top and base of the objectives (although faults exist throughout the

trend they were not included in this project due to the regional scope, a lack of seismic data and the stratigraphic nature of the play)

2. Stratigraphic Cross Sections per project area using NuLook presentation

3. 3D Petrophysical Property Distribution Model

4. Multiple Realizations of property distributions for each project area

5. CSIM (Composite Stratigraphic Image Maps) created

6. Printed Scaled Plots of CSIMs, one each (i.e. Average Porosity (PHIE), Clay Volume, Free Fluid porosity (PHIE-BVI), Average Permeability (PERMSH Avg) and KH (PERMSH Net), VClay, TOC (Total Organic Carbon), HCPV (Hydrocarbon Pore Volume), Structure and Thickness maps (below are some examples of the maps included)

7. Maps can also be delivered electronically in a zmap plus format (maps can be uploaded into different software

packages & overlay maps can be created)

8. Executive Report, Project Binder, and CD

9. NUVIEW PDFs for all wells used in the project (paper copies are available for an additional fee*)

Rock Properties such as, Poisson’s ratio, Young’s modulus, Biot’s constant, pore pressure, overburden pressure, in-situ stress profile descriptions, and brittleness

1. Young’s Modulus is a measure of the stiffness of the rock. It can be obtained from the measurement of dynamic modulus using sonic log measurements. Calculations of Young’s Modulus based on the petrophysical properties of an interval are correlated to core or sonic log measurements, allowing for good predictions in intervals where sonic and core data are not available. This property impacts both the NuStim fracture and production models. Typical Young’s Moduli range from 100,000 to 10,000,000 psi

2. Poisson’s ratio is a rock property which governs the NuStim fracture growth model. It is a component of the stress profile. Poisson’s ratio is defined as the ratio of lateral strain to longitudinal strain. It can be obtained from core measurements or indirectly obtained from sonic log measurements. Calculations of Poisson’s ratio based on the petrophysical properties of an interval are correlated to core or sonic log measurements, allowing for good predictions in intervals where sonic and core data are not available. Poisson’s ratio values typically range from 0.15 to 0.4

3. Brittleness coefficient (%) - Lower values indicate a ductile zone, while higher values indicate a more brittle interval. A brittle zone is more likely to be naturally fractured and to respond positively to waterfrac stimulation techniques

Niobrara-‐Powder River

Regional Field Study

The Powder River Basin is comprised of Northeastern Wyoming and Southeastern Montana. NUTECH has evaluated 62 wells in this area and several more Niobrara wells to the north of the defined area. As of 2002 the USGS estimated 16.5 TCF of gas, 1.5 billion barrels of oil, and 86.5 million barrels of natural gas liquids still undiscovered in this basin.

This study provides a petrophysical and geological analysis of 66 Niobrara wells that allows insight into the connectivity of textural attributes of the wells with NULOOK Shale Analysis and attribute mapping from NUVIEW. Also available to coincide with the study is NUSTIM Geomechanical Analysis that depicts formation brittleness and fracability identification.
