DOE's Unconventional Gas Research  Programs 1976-1995

Beginning about 1976, groundbreaking research directed by the Department of Energy catalyzed several innovative industry ?firsts? that later became commercial technologies, and also resulted in the acquisition, analysis and wide dissemination of an enormous quantity of ?ground truth? data on a topic that at the time generated little interest: unconventional sources of natural gas. At the time, less than 7 percent of the natural gas produced from gas wells came from unconventional sources.

Exploring for Subtle Mission Canyon Stratigraphic Traps with Elastic-Wavefield Seismic Technology

The objective of this project is to develop a new seismic technology that will improve exploration for Mission Canyon oolitic limestone stratigraphic traps in the Williston Basin. This technology involves the acquisition of nine-component (9-C) seismic data that will allow independent P, SH, SV, and C images of geologic targets to be constructed. The integrated use of these images provides more seismic-sequence and seismic-facies information than does conventional P-wave seismic technology. The broader goal is to develop these methods for use in many other stratigraphic environments.

A Seasonal Perspective on Regional Air Quality in Central California- Phase 1

Central California spans a wide variety of urban, agricultural, and natural terrain, including the San Francisco Bay area, the Central Valley, and the Sierra Nevada Mountains. Population within this region is growing rapidly, and there are persistent, serious air pollution problems including fine particulate matter (PM2.5) and ozone. Summertime photochemical air pollution is the focus of the present study, which represents a first phase in the development and application of a modeling capability to assess formation and transport of ozone and its precursors within Central California over an entire summer season. This contrasts with past studies that have examined pollutant dynamics for a few selected high-ozone episodes each lasting 3-5 days. The Community Multiscale Air Quality model (CMAQ) has been applied to predict air pollutant formation and transport in Central California for a 15-day period beginning on July 24, 2000. This period includes a 5-day intensive operating period (July 29 to August 2) from the Central California Ozone Study (CCOS). Day-specific meteorological conditions were modeled by research collaborators at NOAA using a mesoscale meteorological model (MM5). Pollutant emissions within the study domain were based on CARB emission inventory estimates, with additional efforts conducted as part of this research to capture relevant emissions variability including (1) temperature and sunlight driven changes in biogenic VOC, (2) weekday/weekend and diurnal differences in light duty (LD) and heavy-duty (HD) motor vehicle emissions, (3) effects of day-specific meteorological conditions on plume rise from point sources such as power plants. We also studied the effects of using cleaner pollutant inflow boundary conditions, lower than indicated during CCOS aircraft flights over the Pacific Ocean, but supported by other surface, ship-based, balloon and aircraft sampling studies along the west coast.

Development of a 400 Level 3C Clamped Downhole Seismic Receiver Array for 3D Borehole Seismic Imaging of Gas Reservoirs

Borehole seismology is the highest resolution geophysical imaging technique available today to the oil and gas industry for characterization and monitoring of oil and gas reservoirs. However, the industry’s ability to perform high resolution 3D imaging of deep and complex gas reservoirs using borehole seismology has been hampered by the lack of acquisition technology necessary to record large volumes of high frequency, high signal-to-noise-ratio borehole seismic data. This project took aim at this shortcoming by developing a 400 level 3C clamped downhole seismic receiver array, and accompanying software, for borehole seismic 3D imaging. This large borehole seismic array has removed the technical acquisition barrier for recording the data volumes necessary to do high resolution 3D VSP and 3D cross-well seismic imaging

Advanced Seismic While Drilling System

Goal is to design and develop a new, advanced seismic while drilling system that provides real-time vertical seismic profile (VSP) data that allows operators to ?see? ahead of the drill bit and provides, a) lower costs when compared to conventional VSP, b) increased safety and cost savings by detecting unexpected increased pore pressure ahead of the bit, c) allow operators to verify pre-drill reservoir models to ?see? and steer towards more optimal targets, and d) provide new operational capabilities when drilling gas bearing formations at depths greater than 15,000 feet. Technology International, Inc. (TII) is working to design and test acoustically augmented Seismic Drill Bit's (SDB?s) where a unique seismic source is built into a hybrid polycrystalline diamond compact (PDC) -roller cone bit. The new seismic source can be adapted to conventional PDC and roller cone bit types to create seismic signals that can be received by the surface monitoring system from depths beyond 15,000 feet. The acoustic source can be activated at any time, thereby triggering the source to generate acoustic signals required to reflect from formations ahead of the bit, then travel to, and be recorded at the surface. The seismic information will be recorded by Input/Output. Inc. (I/O), and rapidly processed by I/O and Knowledge Systems, Inc. (KSI), in real-time, to provide detailed imaging of targets approximately 600 feet ahead of the bit. Without interfering with normal drilling operations, this integrated approach will provide an advanced seismic while drilling (SWD) system and service to the petroleum industry for real time imaging and warning of impending well control problems.

Energy From the High North

Alaska's fossil energy resources can and will likely play a greater role in meeting the nation's energy needs in the future. Alaska holds about one-fifth of America's remaining proved oil reserves, a significant portion of its natural gas reserves, and over half of its coal resources. When stranded North Slope natural gas and unconventional oil and gas resources such as viscous oil, coalbed natural gas, and methane hydrates are factored in, the potential is incredible. Despite Alaska's energy wealth, there are many challenges to producing and delivering those resources to the rest of the United States, as well as providing affordable power to Alaska's rural villages. NETL is working with industry, academia, and other Government agencies to maximize and show the value of Alaska's fossil fuel resources to the Nation and Alaska's rural community while maintaining the pristine environment in which it is contained.

A Guide to Practical Management of Produced Water from Onshore Oil and Gas Operations in the United States

The make-up of the oil and gas industry in the United States today is different than it was 25 years ago. The domestic oil and gas sector is no longer dominated by large oil and gas companies. Currently, 65 percent of the natural gas and 40 percent of the oil produced in the United States is produced by small independent oil and gas companies which typically employ no more than 10 full-time employees (DOE, 2006 and API, 2006). This core of independent producers might not have the financial aptitude to conduct the research required to make the technological advances necessary to continue to economically produce domestic energy resources, but the domestic oil and gas industry cannot sustain itself without the critical development of new technologies. This is a major concern that is addressed by the United States Department of Energy (DOE) National Energy Technology Laboratory (NETL) through research grants targeted to fill this void.

Novel Use of P- and S-wave Seismic Attenuation for Deep Natural Gas Exploration and Development

Deeply buried gas reservoirs along the Gulf of Mexico shelf are an important future energy resource for the U.S. One of the greatest problems encountered by operators in this area is identifying commercially viable targets for drilling. Because of the great depth of the reservoirs (over 15,000 ft), the most common 3D seismic methods for direct hydrocarbon indication, such as AVO (amplitude versus offset), are not reliable. Many wells have been drilled on deep AVO anomalies, only to find that they contain noncommercial quantities of gas (the so called “fizzwater” problem). Other problems in detecting deep gas formations are caused by inadequate offset in the seismic data acquisition and by high fluid pressures, which tend to make gas look more like water in a seismic sense.

Origin Of Scale-Dependent Dispersivity And Its Implications For Miscible Gas Flooding

The objectives of this project are to perform a novel fundamental study of the mechanism of dispersion, to develop an improved multiscale statistical model of dispersion, and to use this advance in understanding to optimize field scale displacements. A numerical experiment using particle tracking in large scale domains demonstrates that the large echo dispersion coefficients estimated in Mahadevan et al.(2003) are not unreasonable. It could be that irreversible mixing is occurring even in large-scale miscible displacements. For this case, the traditional definition of dispersivity does not apply because the dispersion coefficient does not scale linearly with velocity because of the unidirectional nature of the velocity field. With the use of a heterogeneous velocity field, a linear scaling is expected as demonstrated in particle tracking done on pore-network models(Bruderer and Bernabe 2001).  Our grain-scale simulation studies show that the echo test in parallel layers is scale-dependent when there is transverse flow between layers. We also show that transverse dispersion is significant when velocity fluctuation in the transverse direction is high and that the transverse dispersion value depends on the medium configuration. In this study we calculated transversal and longitudinal dispersion in a 2D homogeneous configuration by applying an inverse fit method to match the simulation concentration data to the 2D analytical solution of the convection-dispersion equation. We show that, in the case of zero diffusion in pore-scale simulations, local mixing would be reversible when flow is at low Reynolds number. The progress to date is meeting the expectations laid out in the project description.

Technology Development and Demonstration/Microholes for Designer Seismics in Support of CO2 EOR

The external objective of this project is to demonstrate that a Coiled Tubing Microhole Drilling Rig can be used to drill shallow (800 feet) instrumentation wells for the installation of the Microhole Vertical Seismic Profile Array in order to monitor the movement of injected Carbon Dioxide into an oil reservoir for the purposes of Enhanced Oil Recovery and Carbon Dioxide Sequestration. As more Carbon Dioxide Enhanced Oil Recovery projects are started and Carbon Dioxide Sequestration proceeds, the need for less expensive monitoring wells will increase and the economics of using Microhole wells will appear more favorable.

Friction Reduction for Microhole CT Drilling

The objective of this 24 month project focused on improving microhole coiled tubing drilling bottom hole assembly (BHA) reliability and performance, while reducing the drilling cost and complexity associated with inclined/horizontal well sections. This was to be accomplished by eliminating the need for a downhole drilling tractor or other downhole coiled tubing (CT) friction mitigation techniques when drilling long (>2,000 ft.) of inclined/horizontal wellbore. The technical solution to be developed and evaluated in this project was based on vibrating the coiled tubing at surface to reduce the friction along the length of the downhole CT drillstring. The Phase 1 objective of this project centered on determining the optimum surface-applied vibration system design for downhole CT friction mitigation. Design of the system would be based on numerical modeling and laboratory testing of the CT friction mitigation achieved with various types of surface-applied vibration. A numerical model was developed to predict how far downhole the surface-applied vibration would travel. A vibration test fixture, simulating microhole CT drilling in a horizontal wellbore, was constructed and used to refine and validate the numerical model. Numerous tests, with varying surface-applied vibration parameters were evaluated in the vibration test fixture. The data indicated that as long as the axial force on the CT was less than the helical buckling load, axial vibration of the CT was effective at mitigating friction. However, surface-applied vibration only provided a small amount of friction mitigation as the helical buckling load on the CT was reached or exceeded. Since it would be impractical to assume that routine field operations be conducted at less than the helical buckling load of the CT, it was determined that this technical approach did not warrant the additional cost and maintenance issues that would be associated with the surface vibration equipment. As such, the project was concluded following completion of Phase 1, and Phase 2 (design, fabrication, and testing of a prototype surface vibration system) was not pursued.

Parallel Multi-grid Finite Element Simulator for Fractured/Faulted and Other Complex Reservoirs Based on a CCA/Breakout

The objectives of this project are to develop an efficient, general-purpose, finite-element simulator with unstructured grids to model complex reservoirs. Most reservoirs are fractured to a certain degree, and now there are better tools to characterize and map faults and fractures, fieldwide. Generation of reservoir domains with faults and fractures using relevant geological information is one of the tasks. This project would make it possible to incorporate this enhanced characterization directly into a reservoir simulation framework.
