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

Goal is to develop and test a new methodology for using seismic attenuation attributes, from multi-component P-wave and S-wave seismic data, for assessing the presence of high oil or natural gas saturations, and estimating reservoir properties (in particular, gas saturation, lithology, porosity, etc). 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 their great depth (over 15,000 feet), the most common 3D seismic methods for direct hydrocarbon indication, such as amplitude versus offset (AVO) have proven unreliable in the past. The approach of this study combines three elements: (1) a synthesis of the latest rock physics understanding of how rock P-wave and S-wave inelasticity is related to rock type, pore fluid types, and pore microstructure, (2) synthetic seismic modeling that will help identify the relative contributions of scattering and intrinsic inelasticity to apparent Q attributes, and (3) robust algorithms that extract relative P- and S- wave attenuation attributes from seismic data. Recognizing the pitfalls of measuring attenuation in-situ, RSI will implement procedures that emphasize relative attenuation anomalies that are calibrated to well log information, and that incorporate empirical and theoretical constraints from rock physics. After developing the necessary methodologies for computing Q from downhole measurements and reflection seismic data, RSI will employ Artificial Neural Network and other methods to link the well-derived reservoir properties to the seismic attenuation attributes. This will provide a quantitative means to interpret Qp and Qs in terms of oil and gas saturation, lithology, porosity, and perhaps even permeability. This will be the ultimate accomplishment of this project. The developed methods will be tested using actual field data to be supplied by U.S.-based oil and gas companies. The data will be analyzed for indications of hydrocarbon accumulation and those results will be compared to data from ?blind? wells that will be withheld from the original analysis.

Integrated Multi-Scale Characterizations of Imbibition and Wettability Phenomena Using Magnetic Resonance and Wide-Band Dielectric Measurements

The objectives of the proposal are to develop methods for obtaining realistic configurations of two immiscible fluids as a function of wettability and geologic characteristics and to use these fluid configurations as a basis for predicting and explaining macroscopic (core-scale) behavior, including the relationships among relative permeability, wettability, and laboratory and log measurements of nuclear magnetic resonance (NMR) and broadband dielectric response. The ultimate objective is to measure dielectric and NMR responses in a range of sedimentary rocks and to use state-of-the-art multi-scale modeling to interpret these measurements to quantify wettability and relative permeability at the core and log scales.

Fluid-Rock Characterization for NMR Well Logging and Special Core Analysis

The objective of this project is to develop the techniques and interpretation methods to determine the maximum information about fluid and rock properties and interactions from in-situ measurements by nuclear magnetic resonance (NMR) well logging and fluid sampling and from special core analysis of formation material. The approach to this objective is from two directions: 1) development of NMR techniques and interpretations for in-situ measurement of these properties by NMR well logging and 2) quantification of pore structure and wettability at the microscopic level to develop forward models for interpretation of multiphase fluid flow and NMR response.

PERMIAN BASIN CORE WORKSHOP-DOE FUNDED RESERVOIR CHAARECTERIZATION PROJECTS

Since the early 1990's, the U.S. Department of Energy has supplied co-funding with the oil industry for a number of projects designed to develop better ways of recovering the vast amount of oil and gas that are presently left behind in mature reservoirs. In many cases, the amount of movable, but unrecovered, hydrocarbons far exceeds the amount produced. This is particularly true for older (Paleozoic), tighter rock units that display dramatic porosity and permeability variations, such as the producing units in the Permian Basin. In particular, the multiple hundred million-barrel fields found in carbonate shelf deposits of the Clear Fork, Glorieta, San Andres and Grayburg formations have been targeted. So too have the tight basinal sandstone reservoirs of the Spraberry formation and the Delaware Mountain Group. In most cases, fields that exist in these formations have yielded less than 35% of their original oil in place, even after C02 flooding. Clearly both the oil industry and the U.S. government would like to discover better ways of increasing production from such reservoirs. Techniques developed during funded projects in particular fields are to be shared with all producers, in the hope that they will benefit everyone and not just the fields and operators for whom the research was undertaken.

Improving Access to Onshore Oil & Gas Resources on Federal Lands

The United States relies on oil and natural gas to supply a significant portion of the nation's energy. These fuels currently supply greater than 60 percent of the nation's energy and are the prime transportation fuels supplying nearly 100 percent of the nation's needs (NEPDG, 2001). The energy needs of the United States are greater than domestic sources are currently supplying, a situation which is expected to continue at an ever increasing rate as the energy needs of the United States rise in the future. The Bush Administration's Energy Policy highlighted the means to meet the nation's future energy needs through conservation, increasing domestic supplies, strengthening the energy infrastructure and increasing alternative and renewable fuels (NEPDG, 2001), while sustaining environmental responsibilities and strengthening foreign alliances. The National Energy Policy Development Group which provided the basis for the Bush Administration's Energy Policy suggested that one way to increase domestic on-shore production is to increase access to federal lands thus producing more of our own oil and natural gas resources. The federal government owns approximately 30 percent of the land in the United States, with much of the nation's public lands estimated to have substantial undiscovered energy resources (NEPDG, 2001) representing a favorable source for increased domestic production. Therefore, access to federal lands for the leasing and development of oil and natural gas resources is critical to meeting the nation's current and future energy demands.

The Application and Use of Microholes for Vertical Seismic Profiling

The project goal is to evaluate and develop ?downward looking? Vertical Seismic Profiling (VSP) technology for microholes to be used to enhance image resolution and depth of investigation beyond current technology. The potential low cost and high resolution possible through this approach to subsurface imaging might allow, for the first time, geophysicists to pick borehole locations for an optimized, cost effective VSP network for long term monitoring, as opposed to the typical VSP using existing production holes for limited testing.

Carbon-Dioxide-Enhanced Oil Production from the Citronelle Oil Field in the Rodessa Formation, South Alabama

The partners Alabama A&M University, Denbury Resources Inc., Geological Survey of Alabama, Southern Company, University of Alabama, University of Alabama at Birmingham, and University of North Carolina at Charlotte will conduct CO2 injection tests in Citronelle oilfield in Mobile County, AL. The project will introduce CO2 enhanced oil recovery (EOR) for tertiary recovery from Alabama's uniquely structured oil reservoirs, providing oilfield operators and CO2 producers with improved estimates of oil yields from EOR and the capacity of depleted reservoirs to sequester CO2. The research work will improve the reliability of computer simulations of oil yield from CO2-EOR and calculations of sequestration capacity and the rate at which CO2 can be introduced into underground formations. The simulations of Citronelle field will be integrated with computer visualizations of the migration of oil, water, and CO2, making the results accessible to reservoir engineers, geologists, utility planners, and climate-change modelers

NOVEL HIGH-SPEED DRILLING MOTOR FOR OIL EXPLORATION & PRODUCTION

The overall objective of this effort is to develop, build and test a high-speed drilling motor that can meet the performance guidelines of the announcement1, namely: ?The motors are expected to rotate at a minimum of 10,000 rpm, have an OD no larger than 7 inches and work downhole continuously for at least 100 hours. The motor must have common oilfield thread connections capable of making up to a drill bit and bottomhole assembly. The motor must be capable of transmitting drilling fluid through the motor.? To these goals, we would add that the motor must be economically viable, in terms of both its manufacturing and maintenance costs, and be applicable to as broad a range of markets as possible.

Synthesis and Evaluation of CO2 Thickeners Designed with Molecular Modeling

The objective of this research is to use molecular modeling techniques, coupled with our prior experimental results, to design, synthesize and evaluate inexpensive, non-fluorous carbon dioxide thickening agents. The first type of thickener to be considered is associating polymers. Typically, these thickeners are copolymers that contain a highly CO2-philic monomer, and a small concentration of a CO2-phobic associating monomer. Yale University will be solely responsible for the synthesis of a second type of thickener; small, hydrogen bonding compounds. These molecules have a core that contains one or more hydrogen-bonding groups, such as urea or amide groups. Non-fluorous, CO2-philic functional groups will be attached to the hydrogen bonding core of the compound to impart CO2 stability and macromolecular stability to the linear ?stack? of these compounds. The third type of compound under investigation is CO2-soluble surfactants. These surfactants contain conventional ionic head groups and composed of CO2-philic oligomers (short polymers) or small compounds (sugar acetates) previously identified by our research team. Mobility reduction could occur as these surfactant solutions contacted reservoir brine during CO2 injection, or via the self-assembly of surfactants into viscosity enhancing cylindrical micelles. This report thoroughly documents the synthesis and characterization of the first series of nonfluorous, ionic, highly CO2-soluble surfactants that has been reported. Specific tails include oligo(vinyl acetate), sugar acetates, and oligo(propylene oxide). The surfactants with vinyl acetate tails were particularly promising. The report also includes preliminary foam stability test results conducted in a high pressure view cell. Several of the surfactants, most notably those with oligomeric vinyl acetate tails, yielded the most stable foams. Our subsequent work will investigate the ability of these surfactant solutions to generate stable foams in a brine-saturated sandstone core with our colleague Reid Grigg at New Mexico Tech PRRC.

Microhole Coiled Tubing Drilling Operational Study

The DOE microhole coiled tubing drilling project aims to reduce the cost of drilling and completing a well by using coiled tubing to drill a microhole. Past experience has shown that a sufficient level of action must be sustained to keep the unit operating if the cost of drilling a well with coiled tubing is to be reduced. The development of microhole completions is relatively recent and the supplier base and available tools are limited. For the purposes of this study, therefore, rather than designing a unit exclusively for the microhole completion market, a maximum completion size has been determined that will maximize the unit's potential by enabling it to be used by a greater portion of the drilling market. Based on research into current shallow well drilling areas and the types of completions involved, a theoretically ideal wellbore schematic has been developed with a maximum total measured depth (TJVID) o f 6,000 ft and a final completion size no greater than 4-1 / 2 in., bearing in mind that a surface and intermediate string might also be needed  to isolate different hole coalitions.  The conductor will be rotary-drilled in all completions, requiring the use of a device to rotate the drill pipe or auger. Chapter 10 of this study discusses continuous rotary devices.

Microhole Coiled Tubing Drilling Concept Design/Business Plan

A market analysis was performed on the shallow drilling market within the United States and Canada. The goal of the market analysis was to identify key trends and the current state of the industry. The key item of the market analysis is the lack of a current microhole market to evaluate. Therefore trends needed to be inferred from current shallow drilling activity. The current drilling activity trends definitely indicate that there is a potential market for coiled tubing drilling in the United States. The market has been well established in Canada and the technology should be easily adaptable to the United States market. In trying to establish a business case for Microbolic drilling it became apparent that a Microhole Coiled Tubing Drilling Rig would need to be capable of performing other operations to keep utilization high enough keep the cost per job down until the Microhole Market can be better established. An operational study was performed to evaluate the operation of coiled tubing drilling rigs and to better understand all the parameters that might have a bearing on the design and efficiency of a Metohole Coiled Tubing Drilling Rig (MCTR). The information gathered in the operational study was used to evaluate existing coiled tubing drilling rigs. During the evaluation we looked at different efficiency features and the ability of the equipment to perform the desired task within our scope of work. Many of the existing coiled tubing drilling units are very efficient and perform well in the area in which they operate. The major obstacle that we found is that the majority of the units are overweight or over dimension for use in the United States. This made the selection of a unit to evaluate at our Rosharon test site difficult as any unit selected to be modified would not meet the requirements of being DOT road legal.
