Marcellus Gas Shale Project

2009 Unconventional Resources

Project Number: 09122-04 Project Status: completed
Start Date: Nov. 10, 2010 End Date: June 10, 2013
RPSEA PM: Kent Perry Principal Investigator: Iraj Salehi
Subcontractor: Gas Technology Institute
Project Objectives:

The objective of the project is to create an innovative user-friendly software prototype (called DomAnal) that can be used by operators to characterize flow properties of stimulation domains, diagnose well stimulations, and provide options to improve well stimulations. DomAnal shall be a fast analytic screening model, with appropriate approximations, rather than a slow completely rigorous numerical model, such as finite elements.

Prediction of Fault Reactivation in Hydraulic Fracturing of Horizontal Wells in Shale Gas Reservoirs

2009 Unconventional Resources

Project Number: 09122-06 Project Status: completed
Start Date: Jan. 19, 2011 End Date: Aug. 31, 2015
RPSEA PM: Skip Pratt Principal Investigator: Ebrahim Fathi
Subcontractor: West Virginia University Research Corporation
Project Objectives:

The overall objective is to develop a fundamental basis for characterization of geomechanical performance of shale gas reservoirs in the process of hydraulic fracturing stimulation. This effort shall focus on predicting fault reactivation (shear slippage) and improving effectiveness of hydraulic fracturing stimulation to enhance production of horizontal gas shale wells, targeting the Marcellus shale in the Appalachian Basin.

Simulation of Shale Gas Reservoirs Incorporating Appropriate Pore Geometry and the Correct Physics of Capillarity and Fluid Transport

2009 Unconventional Resources

Project Number: 09122-11 Project Status: completed
Start Date: Nov. 4, 2010 End Date: May 1, 2014
RPSEA PM: Kent Perry Principal Investigator: Deepak Devegowda
Subcontractor: Board of Regents of the University of Oklahoma
Project Objectives:

The objective of this project is to provide to the exploration and production industry commercial simulators for shale gas reservoirs that incorporate the necessary physical approximations and pore geometries to provide a valid model of gas and water production. To facilitate adoption and use by E&P professionals the objective is to modify current commercial simulators by substitution of new modules containing more appropriate approximations and pore geometries.

Using Single-Molecule Imaging System Combined with Nano-Fluidic Chips to Understand Fluid Flow in Tight and Shale Gas Formation

2009 Unconventional Resources

Project Number: 09122-29 Project Status: completed
Start Date: Feb. 11, 2011 End Date: Aug. 31, 2014
RPSEA PM: Kent Perry Principal Investigator: Baojun Bai
Subcontractor: The University of Missouri
Project Objectives:

The objective of the project is to improve the understanding of the flow behavior of natural gas and introduced fluids (water, surfactant solutions and polymers) in the nano-darcy range of tight gas and shale formations by using advanced single-molecule imaging system combined with nano-fluidic chips and pore-scale numerical simulation techniques. Specifically, the Subcontractor will examine the flow behavior of gas and introduced fluids in the nano-scale pores and cracks in tight formations and study the effect of introduced fluids on natural gas transportation properties, such as capillary pressure, absolute permeability, relative permeability, non-Darcy flow. The difference of fluid flow in shale and tight sand formations will be also identified.

Geomechanical Model for Gas Shales Based on the Integration of Stress Measurements and Petrophysical Data From the Greater Marcellus Gas System

RPSEA PM: Skip Pratt Principal Investigator: Terry Engelder
Subcontractor: Pennsylvania State University
Project Objectives:

The objectives of the project is to collect stress profiles in three wells in the Marcellus gas system, interpret them employing a full suite of lag and core based petrophysical data, and to develop a geomechanical model that can be used when engineering stimulations are required.

Improved Drilling and Fracturing Fluids for Shale Gas Reservoirs

2009 Unconventional Resources

Project Number: 09122-41 Project Status: completed
Start Date: Dec. 1, 2010 End Date: June 30, 2014
RPSEA PM: Charlotte Schroeder Principal Investigator: Mukul Sharma
Subcontractor: The University of Texas at Austin
Project Objectives:

The primary objective of the proposal is to lower the cost of drilling and improve the effectiveness of fracture treatments in shale gas reservoirs. This is proposed to be accomplished through, (a) The development and field-testing of nanoparticle based water-base drilling fluids which are less expensive than currently used oil-base drilling fluids, and (b) The addition of nanoparticles to minimize water blocking in slick-water fracs in shale gas reservoirs.

NORM Mitigation and Clean Water Recovery from Marcellus Frac Water

2010 Unconventional Resources

Project Number: 10122-07 Project Status: completed
Start Date: Jan. 27, 2012 End Date: March 30, 2014
RPSEA PM: Kent Perry Principal Investigator: James Silva
Subcontractor: GE Global Research
Project Objectives:

The project objective was to develop a cost-effective process to recover distilled water and a salable salt product from Marcellus frac water. The first goal was to develop a pretreatment process that removes NORM, particularly 226Ra, from frac water and enables disposal of a NORM-concentrate in an environmentally responsible manner. The second goal was to develop a brine concentrator based on membrane distillation (MD) that is suitable for Marcellus frac water desalination and is significantly less capital cost-intensive than currently available evaporators. The emphasis of both objectives is that pretreatment and brine concentration may be accomplished in mobile facilities. It is anticipated that crystallization will occur in a central treatment facility. The successful execution of this project should reduce the cost and environmental impact of hydrofracturing.
