Thin-film forces in pseudoemulsion films

Description: Use of foam for enhanced oil recovery (EOR) has shown recent success in steam-flooding field applications. Foam can also provide an effective barrier against gas coning in thin oil zones. Both of these applications stem from the unique mobility-control properties a stable foam possesses when it exists in porous media. Unfortunately, oil has a major destabilizing effect on foam. Therefore, it is important for EOR applications to understand how oil destroys foam. Studies all indicate that stabili… more

Chemical flooding in a virtual environment - a survivor`s guide to VR development

Description: Building something which could be called {open_quotes}virtual reality{close_quotes} (VR) is something of a challenge, particularly when nobody really seems to agree on a definition of VR. The author wanted to combine scientific visualization with VR, resulting in an environment useful for assisting scientific research. He demonstrates the combination of VR and scientific visualization in a prototype application. The VR application constructed consists of a dataflow based system for performing s… more

Description: This report is a permanent record of a poster paper presented by the authors at the Third International Reservoir Characterization Technical Conference in Tulsa, Oklahoma on November 3--5, 1991. The subject is electromagnetic (EM) techniques that are being developed to monitor oil recovery processes to improve overall process performance. The potential impact of EM surveys is very significant, primarily in the areas of locating oil, identifying oil inside and outside the pattern, characterizing… more

Practical hot oiling and hot watering for paraffin control

Description: One of the common oil-field wellbore problems is paraffin deposition. Even though hot oiling or hot watering is usually the first method tried for removing paraffin, few operators appreciate the limitations of ``hot oiling`` and the potential for the fluid to aggravate well problems and cause formation damage. Field tests have shown that the chemical and thermal processes that occur during ``hot oiling`` are very complex and that there are significant variations in practices among operators. Ke… more

Measurement-while-drilling (MWD) development for air drilling

Description: The objective of this program is to tool-harden and make commercially available an existing wireless MWD tool to reliably operate in an air, air-mist, or air-foam environment during Appalachian Basin oil and gas directional drilling operations in conjunction with downhole motors and/or (other) bottom-hole assemblies. The application of this technology is required for drilling high angle (holes) and horizontal well drilling in low-pressure, water sensitive, tight gas formations that require air,… more

Observations of broad-band micro-seisms during reservoir stimulation

Description: During hydrocarbon reservoir stimulation such as hydraulic fracturing, the cracking and slippage of the formation results in the emission of seismic energy. The objective of this study was to determine the properties of these induced micro-seisms. A hydraulic fracture experiment was performed in the Piceance Basin of Western Colorado to induce and record micro-seismic events. The formation was subjected to four processes; breakdown/ballout, step-rate test, KCL mini-fracture, and linear-gel mini… more

Subsurface fracture mapping using microearthquakes detected during primary oil production, Clinton County, Kentucky

Description: Downhole microseismic monitoring tests were conducted in Clinton County, Kentucky to determine if microearthquakes associated with primary production could be detected on a scale of interwell distances ({>=}400 ft) and to determine if such microearthquakes could be used to map reservoir fractures. The oil reservoirs occur in shallow (750 to 2400 ft), low-porosity (< 2%), carbonate rocks of Ordovician age. The reservoir system controlling the occurrence and flow of off and its relationship to th… more

Site evaluation criteria for a horizontal well in the Clinton Sandstone, Mahoning County, Ohio

Description: A joint study between USDOE/METC and GRI was initiated to evaluate the application of horizontal wells for improving production from Clinton Sandstone reservoirs in eastern Ohio. A contract was awarded by USDOE/METC to Belden & Blake Inc. for drilling a horizontal well on their lease holdings in Mahoning Co., Ohio. Through a site evaluation study, reservoir and in situ stress characteristics were determined and well geometry designed. GRI contracted CER Corp. to drill a preliminary vertical wel… more

Microbial enhancement of oil recovery: Recent advances. Proceedings

Description: During recent years, systematic, scientific, and engineering effort by researchers in the United States and abroad, has established the scientific basis for Microbial Enhanced Oil Recovery (MEOR) technology. The successful application of MEOR technology as an oil recovery process is a goal of the Department of Energy (DOE). Research efforts involving aspects of MEOR in the microbiological, biochemical, and engineering fields led DOE to sponsor an International Conference at Brookhaven National … more

Super critical fluid extraction of a crude oil bitumen-derived liquid and bitumen by carbon dioxide and propane

Description: Supercritical fluid extraction of complex hydrocarbon mixtures is important in separation processes, petroleum upgrading and enhanced oil recovery. In this study, a paraffinic crude oil, a bitumen- derived liquid and bitumen were extracted at several temperatures and pressures with carbon dioxide and propane to assess the effect of the size and type of compounds that makeup the feedstock on the extraction process. It was observed that the pure solvent density at the extraction conditions was no… more

The use of broadband microseisms for hydraulic fracture mapping

Description: When a hydrocarbon reservoir is subjected to a hydraulic fracture treatment, the cracking and slipping of the formation results in the emission of seismic energy. The objective of this study was to determine the advantages of using broadband (100 Hz to 1500 M) microseismic emissions to map a hydraulic fracture treatment. A hydraulic fracture experiment was performed in the Piceance Basin of Western Colorado to induce and record broadband microseismic events. The formation was subjected to four … more

Deep heavy oil recovery by steam injection using twin horizontal drainholes

Description: We propose a novel method for improving the efficiency of recovery of heavy oil. Two horizontal drainholes are made at the bottom of a vertical well so that one may be steamed while the other is in production. Downgoing steam and rising produced fluids are carried in the same vertical casing so that heat from the produced fluids reduces heat losses from the steam. This arrangement requires a downhole valve that will switch steam and produced fluids between the boreholes. We discuss the design o… more

An adaptive finite element methodology for 2D simulation of two-phase flow through porous media

Description: A scheme for the accurate simulation of two-phase flow through porous media, utilizing adaptive finite element methods is presented. The theoretical equations and their approximation using Galerkin`s method is covered, followed by a discussion of a dynamically refined mesh which preserves piece wise solutions across transition elements. Finally, comparisons are made between results of computed simulations and laboratory experiments. The paper uses the processes occurring in a water coning scena… more

The rock melting approach to drilling

Description: During the early and mid-1970`s the Los Alamos National Laboratory demonstrated practical applications of drilling and coring using an electrically-heated graphite, tungsten, or molybdenum penetrator that melts a hole as it is slowly pushed through the rock or soil. The molten material consolidates into a rugged glass lining that prevents hole collapse; minimizes the potential for cross-flow, lost circulation, or the release of hazardous materials without casing operations; and produces no cutt… more
