Fundamentals of reservoir surface energy as related to surface properties, wettability, capillary action, and oil recovery from fractured reservoirs by spontaneous imbibition

The objective of this project is to increase oil recovery from fractured reservoirs through improved fundamental understanding of the process of spontaneous imbibition by which oil is displaced from the rock matrix into the fractures. Spontaneous imbibition is fundamentally dependent on the reservoir surface free energy but this has never been investigated for rocks. In this project, the surface free energy of rocks will be determined by using liquids that can be solidified within the rock pore space at selected saturations. Thin sections of the rock then provide a two-dimensional view of the rock minerals and the occupant phases. Saturations and oil/rock, water/rock, and oil/water surface areas will be determined by advanced petrographic analysis and the surface free energy which drives spontaneous imbibition will be determined as a function of increase in wetting phase saturation. The inherent loss in surface free energy resulting from capillary instabilities at the microscopic (pore level) scale will be distinguished from the decrease in surface free energy that drives spontaneous imbibition.

Combined Borehole Seismic and Electromagnetic Inversion

The objectives of the project are to: - Demonstrate the feasibility for the joint quantitative inversion of borehole seismic and electromagnetic (EM) measurements, well logs, and core data. -Develop the necessary computer algorithmic and software infrastructure to jointly invert borehole seismic and EM data into 3-D spatial distributions of petrophysical properties (e.g., porosity, permeability, permeability anisotropy, and fluid saturations). -Evaluate specific configurations for deep sensing borehole EM and seismic instruments that will provide optimal spatial resolutions and penetration length. - Assess the inversion algorithms on synthetic reservoir models constructed from paradigms of highly laminated sands, tight reservoirs, dual-porosity carbonates, and naturally fractured formations. Some of the synthetic reservoir models will be based on actual hydrocarbon reservoir models and data thereof provided to us by Anadarko Petroleum Corporation and Unocal Corporation.

Combined Borehole Seismic and Electromagnetic Inversion for High-Resolution Petrophysical Assessment of Hydrocarbon Reservoirs

This project has two primary goals. The first is to advance the conceptual design of a new generation of deep-sensing borehole electromagnetic (EM) and seismic instruments that can provide 3-D images of reservoir flow units and of their petrophysical properties to distances of tens of meters from the wellbore. The second involves the development of efficient numerical algorithms and computer codes for the joint inversion of borehole seismic and EM measurements. These algorithms will integrate data governed by multi-phase fluid flow, visco-elastic, and electric phenomena into consistent 3-D images of lithology, porosity, permeability, and fluid saturation. Use of borehole seismic measurements in addition to EM measurements will reduce non-uniqueness and hence will improve the accuracy of the estimated petrophysical parameters. Deterministic and stochastic inversion techniques will be used to estimate reservoir-scale distributions of petrophysical properties.

Advancement of flash hydrogasification. Quarterly technical progress report, July-September 1984

The design of test hardware and process development unit (PDU) modifications had been completed previously. Task VII involves the fabrication of test hardware and the modification of an existing 1-ton/h hydroliquefaction PDU at Rockwell's facilities for use as a hydrogasifier test facility. Modifications to the PDU have been completed. The modified facility is designed to accommodate both 10- and 20-ft-long hydrogasifier reactors so that residence times will be in the range of 2 to 6 s when coal is fed at a nominal 1/2 ton/h into reactors at 1000-psia pressure. Provisions have been made for real-time analysis of the product gases using an on-line gas chromatograph system. Separate supplies of coal, hydrogen, oxygen, methane, and water (for steam generation) are also provided. The facility and hardware changes now permit short-duration (1 to 2 h) hydrogasification tests and preburner assembly performance evaluation tests to be conducted to meet the test program objectives. Test program planning and scheduling were approved by DOE in July, and programming of test data reduction programs was completed. During August, activation of the PDU was completed and testing was initiated. This involved conducting preburner performance characterization/checkout tests and the first two coal reactor tests. In general, the preburner assembly performed well and according to design; operation of the PDU has been smooth. Carbon conversions for the baseline (low steam concentration) coal hydrogasification tests were near predicted values

Dielectric Properties of Low-Level Liquid Waste

The purpose of this study was to develop a data collection containing values for the dielectric properties of various low-level liquid waste (LLLW) stimulants measured as a function of frequency, temperature, and composition. The investigation was motivated by current interest in the use of microwave processing for the treatment of radioactive waste. A large volume of transuranic liquid and sludge produced by the U.S. Department of Defense (DOD) during the production of nuclear fuel bars is stored at several U.S. Department of Energy (DOE) sites around the United States. Waste storage and disposal space is scarce, expensive, and must be minimized. Thus, several DOE sites are pursuing the use of microwave heating as a means of achieving volume reduction and solidification of low-level liquid wastes.

Latin America's Decontamination and Decommissioning Needs

The nations of Latin America and the Caribbean have experienced profound change since the tumultuous decades of the 1970s and 1980s. These changes include the return of formal democracy, the implementation of economic reform and stabilization, the embrace of free trade, and an ever-growing awareness of the need for environmental regulation, protection, and remediation. This new concern for the environment reflects not only the dramatic political changes the region has experienced over the past fifteen years but, more significantly, societal change and the structural economic transformation of many of the nations into open, export-oriented economies.

DEVELOPMENT AND OPTIMIZATION OF GAS-ASSISTED GRAVITY DRAINAGE (GAGD) PROCESS FOR IMPROVED LIGHT OIL RECOVERY

This is the final report describing the evolution of the project ?Development and Optimization of Gas-Assisted Gravity Drainage (GAGD) Process for Improved Light Oil Recovery? from its conceptual stage in 2002 to the field implementation of the developed technology in 2006. This comprehensive report includes all the experimental research, models developments, analyses of results, salient conclusions and the technology transfer efforts. As planned in the original proposal, the project has been conducted in three separate and concurrent tasks: Task 1 involved a physical model study of the new GAGD process, Task 2 was aimed at further developing the vanishing interfacial tension (VIT) technique for gas-oil miscibility determination, and Task 3 was directed at determining multiphase gas-oil drainage and displacement characteristics in reservoir rocks at realistic pressures and temperatures.

Improvement of Sweep Efficiency in Gas Flooding

Miscible and near-miscible gasflooding has proven to be one of the few cost effective enhance oil recovery techniques in the past twenty years. The sweep efficiency of such processes is often not high because of the adverse viscosity ratio and density difference between the solvent gas and the oil as well as the reservoir heterogeneity. Water-alternating-gas processes are often used to improve sweep efficiency. Foams and direct thickeners have been developed, but not used in field routinely. Effect of new well architectures on sweep efficiency is poorly understood. As the scope of miscible flooding is being expanded to medium viscosity oils in shallow sands in Alaska and shallower reservoirs in the lower 48, there are questions about sweep efficiency in near-miscible regions. The goal of this research is to evaluate sweep efficiency of various miscible processes in a laboratory model and develop numerical tools to estimate them in fields. Continuous gasflood in the VAPEX mode at 200 psi recovers about 0.62 PV of oil in about 2 PV ethane injection. This recovery is higher than waterflood recovery (~0.48 PV) and gas injection followed by water injection recovery (~0.55 PV) in the quarter 5-spot mode. As the distance between the injectors well and producer well decreases, the oil recovery and recovery rate decreases. Gravity override is observed for gas injection simulations in vertical (X-Z) cross-sections. Breakthrough recovery efficiency increases with the viscous-to-gravity ratio in the range of 1-100. There is little gravity segregation for gravity numbers below 0.02. Above Ng of 0.5, the gravity tongue is well developed. Plans for the next six months include experimental quarter five-spot foam floods, VAPEX floods, and modeling.

Modeling of Yield-Power-Law Type of Drilling Fluid Loss in Naturally Fractured Reservoirs

Lost circulation is the loss of the drilling fluid from the borehole through porous formations, crevices or fractures. Because of higher severity and frequency of losses in fractured formations, industry has been recently focused on the quantitative analysis of drilling mud losses into natural fractures. Several models have been developed but most of them have limited application potential

Study of Cuttings Transport Using Foam with Drill Pipe Rotation under Simulated Downhole Conditions

This report presents experimental and simulation results for foam flow with drill pipe rotation. In this study, the Dynamic Testing Facility (DTF) was modified to study the effects of drill pipe rotation on foam flow. Experiments were conducted for aqueous and polymeric foams with qualities ranging from 0.6 to 0.9 under different flow rates. Foam rheology were also tested using the pipe viscometer on the DTF and compared with rheology measurements using the FGV and the ACTF, respectively. Results show that pipe rotation increases pressure drop for lower quality foams (below 70%), but slightly decreases pressure drop for higher quality foams (above 80%). Calibration results of two nuclear densitometers are presented. Preliminary CFD simulations with pipe rotation in both concentric and eccentric annuli are discussed.

Modeling of Casing Running in High Angle Wells

Following the development of Mitchell, this report presents a mathematical study of 2-D Soft and Stiff String Torque Analysis with pipe rotation, and a 3-D Soft and Stiff String Drag Analysis with pipe running in and pulling out. The Torque Analysis has revealed some defects in the conventional formulation. Compared with conventional formulation, for pipe rotation, the term square root of (1   ?f^2) needs to be included in the contact force calculation. Comparing the torque calculation equations of 2D Soft and Stiff models, the calculated results are very close. The change in azimuth results in different doglegs of wellbore, which has great effect on axial force transfer.

Predicting Dynamic Barite Sag in Oil Based Drilling Fluids

Barite sag continues to be a recurring, potentially serious problem on many directional wells. It could lead to a variety of major drilling problems, including lost circulation, well-control difficulties, poor cement jobs, and stuck pipe. The term “barite sag” is used because barite is the traditional weight material used in drilling fluids to increase the density. Nowadays, there are barite substitutes like: Micromax (manganese tetraoxide), Hematite, Calcium carbonate, Ilmenite (iron titanium oxide) among others. However, Barite is the most widely used weight material it offers high density with wide availability, favorable economics, and it is environmentally friendly

Analysis of Deep Seismic Reflection and other Data from the Southern Washington Cascades

Limited possibilities exist for new hydrocarbon exploration regimes in the Pacific Northwest. Our goal in this presentation is to outline recent knowledge concerning a possible new exploration environment in the State of Washington. This frontier area occurs in southwestern Washington where extensive geophysical studies have been used to outline a proposed sedimentary basin hidden beneath volcanic rocks in the southern Cascades region (Stanley et. ai, 1992). Electrical geophysical imaging using the magnetotelluric (MT) method first detected thick, electrically-conductive sequences believed to be associated with Eocene to Oligocene marine sedimentary rocks. The conduct.ive section occurs at depths from about 1 km to 10 km in the southern Cascades region with thicknesses up to 10 km. Careful consideration of physical properties and the correspondence of the morphology of the units to known fold sets suggests that the high conductivities are related to lithologic/stratigraphic units rather than to variations in physical properties. Our preference for the lithology of the anomalous section, based upon a study of. regional geology and structure, is one dominated by marine shales of Eocene and older in age. Other possible lithologies that have been evaluated for the conductive section include non-marine sedimentary units of Tertiary age, highly altered volcanic flows, and pre-Tertiary metasedimentary rocks with large percentages of graphite. We refer to this anomalously conductive region as the southern Washington Cascades conductor (SWCC, Fig. 1).

Rural Alaska Coal bed Methane: Application of New Technologies to Explore and Produce Energy

The conventional method of power generation in the remote and rural areas of Alaska involves use of diesel powered electric generators. Use of diesel for power generation in remote areas is very expensive because of high diesel price and additional transportation costs to remote locations. A possible alternative for power generation in the remote areas of Alaska is use of natural gas associated with coal deposits, known as coal bed methane (CBM). Alaska has the largest coal deposit in the entire US. The CBM potential in Alaska has been estimated to be 1000 trillion cubic feet (TCF) methane in place. The Alaska Division of Geological and Geophysical Survey has determined that over 37 remote villages are situated on or are immediately adjacent to coal deposits. Therefore, Alaska's vast coal reserve could potentially provide clean and low cost power to the rural areas if the CBM could be harnessed.

Study on Effective Hole Cleaning Using : "Conventional and Enhanced Sweeps in Horizontal Wellbores"

This is the first report that presents literature review, experimental work and recent developments in this project. The experimental work consists of static tests and preliminary “Enhanced Sweeps”. This report includes the first batch of experimental results obtained from the tests conducted on the SSL (Small Sweep Loop) flow loop as well as preliminary successful static test results for oil droplet attachments. Based on results from preliminary flow loop tests, subsequent “Enhanced sweep” tests were conducted according to a modified Test Matrix. A preliminary analysis of the experimental data obtained is presented. The effects of parameters such as rheology, flow rate, bed heights and pressure drop are presented. The focus of this report will be the results from the “Enhanced Sweep” tests. The research also shows some interesting behavior of oil droplets attaching to cuttings. Because of the buoyant ability of the oil, it tends to lift the particle in the drilling fluid.
