Preliminary technical and legal evaluation of disposing of nonhazardous oil field waste into salt caverns (open access)

Preliminary technical and legal evaluation of disposing of nonhazardous oil field waste into salt caverns

Caverns can be readily formed in salt formations through solution mining. The caverns may be formed incidentally, as a result of salt recovery, or intentionally to create an underground chamber that can be used for storing hydrocarbon products or compressed air or disposing of wastes. The purpose of this report is to evaluate the feasibility, suitability, and legality of disposing of nonhazardous oil and gas exploration, development, and production wastes (hereafter referred to as oil field wastes, unless otherwise noted) in salt caverns. Chapter 2 provides background information on: types and locations of US subsurface salt deposits; basic solution mining techniques used to create caverns; and ways in which salt caverns are used. Later chapters provide discussion of: federal and state regulatory requirements concerning disposal of oil field waste, including which wastes are considered eligible for cavern disposal; waste streams that are considered to be oil field waste; and an evaluation of technical issues concerning the suitability of using salt caverns for disposing of oil field waste. Separate chapters present: types of oil field wastes suitable for cavern disposal; cavern design and location; disposal operations; and closure and remediation. This report does not suggest specific numerical limits for such factors …

Summary of wells validated during fiscal years 1991 to 1992 (open access)

Summary of wells validated during fiscal years 1991 to 1992

The Well Validation Project was initiated in fiscal year 1990, with the intended purpose to evaluate wells on the Nevada Test Site. During fiscal years 1991 and 1992, a temperature/electrical conductivity logging tool was redesigned and a thermal-pulse flowmeter logging tool was developed. Seven wells were evaluated during this time period: USGS HTH {number_sign}1, UE-18r, UE-14b, HTH {open_quotes}E{close_quotes}, USGS Test Well B Ex., UE-1q, and UE-5n. The validation techniques used at each site varied depending on the site-specific objectives. Thermal-pulse flowmeter surveys were carried out in several of the wells with limited success. The thermal-pulse flowmeter was designed for boreholes 2 to 6 inches in diameter, most wells at the Nevada Test Site are generally much larger in diameter, 10 to 24 inches. Therefore, the thermal-pulse flowmeter was outfitted with an inflatable rubber packer, which constricts borehole flow through the thermal-pulse flowmeter, increasing the resolution. The thermal-pulse flowmeter can be outfitted with various-sized packers depending on the borehole diameter to be evaluated; these packers are commercially available. The packers are inflated with borehole fluid via a small submersible pump which was designed, built, and tested as part of this study.

Geochemistry of summit fumarole vapors and flanking thermal/mineral waters at Popocatepetl Volcano, Mexico (open access)

Geochemistry of summit fumarole vapors and flanking thermal/mineral waters at Popocatepetl Volcano, Mexico

Popocatepetl Volcano is potentially devastating to populations living in the greater Mexico City area. Systematic monitoring of fumarole gases and flanking thermal/mineral springs began in early 1994 after increased fumarolic and seismic activity were noticed in 1991. These investigations had two major objectives: (1) to determine if changes in magmatic conditions beneath Popocatepetl might be reflected by chemical changes in fumarolic discharges and (2) to determine if thermal/mineral spring waters in the vicinity of Popocatepetl are geochemically related to or influences by the magmatic system. This report summarizes results from these two discrete studies.

USE OF SLIMHOLE DRILLING TO REDUCE WELL COSTS 30-50%: ARNIM PROSPECT

This report highlights the drilling of two shallow oil wells in Fayette County, Texas. The operator of these two wells was Stanton Mineral Development, Inc. The aim of this project was to successfully complete the two (2) wells, emphasizing tight oversight of the technological aspects, neglect of which are the primary causes of failure in this mature producing region as well as unnecessarily expensive wells. Discussions contained here within are not limited to just the execution of the project itself, but a historical and technical analysis which forms a basis for the decisions made both during drilling and completion. Additionally, there is substantial dialogue covering the financial benefits associated with the findings of this project.

Geochemical study of evaporite and clay mineral-oxyhydroxide samples from the Waste Isolation Pilot Plant site (open access)

Geochemical study of evaporite and clay mineral-oxyhydroxide samples from the Waste Isolation Pilot Plant site

Samples of clay minerals, insoluble oxyhydroxides, and their host evaporites from the WIPP site have been studied for their major and minor elements abundances, x-ray diffraction characteristics, K-Ar ages, and Rb-Sr ages. This study was undertaken to determine their overall geochemical characteristics and to investigate possible interactions between evaporates and insoluble constituents. The evaporite host material is water-soluble, having Cl/Br ratios typical of marine evaporites, although the Br content is low. Insoluble material (usually a mixture of clay minerals and oxyhydroxide phases) yields very high Cl/Br ratios, possibly because of Cl from admixed halide minerals. This same material yields K/Rb and Th/U ratios in the normal range for shales; suggesting little, if any, effect of evaporite-induced remobilization of U, K, or Rb in the insoluble material. The rare-earth element (REE) data also show normal REE/chondrite (REE/CHON) distribution patterns, supporting the K/Rb and Th/U data. Clay minerals yield K-Ar dates in the range 365 to 390 Ma and a Rb-Sr isochron age of 428 {+-} 7 Ma. These ages are well in excess of the 220- to 230-Ma formational age of the evaporites, and confirm the detrital origin of the clays. The ages also show that any evaporite or clay mineral …

Deep Injection Wells: EPA Needs to Involve Communities Earlier and Ensure That Financial Assurance Requirements Are Adequate (open access)

Deep Injection Wells: EPA Needs to Involve Communities Earlier and Ensure That Financial Assurance Requirements Are Adequate

A letter report issued by the General Accounting Office with an abstract that begins "Billions of gallons of hazardous liquid waste are injected into underground wells each year. These Class I hazardous deep injection wells are designed to inject waste into an area below the lowermost underground source of drinking water. EPA and the states grant permits to commercial operators to construct and operate these wells and must obtain public comments on the permits. Communities often raise concerns about well safety and other matters. GAO examined the extent to which EPA and the states (1) address these community concerns, (2) consider environmental justice issues, and (3) ensure that financial assurances adequately protect the taxpayer if bankruptcy occurs. GAO, among other things, examined the permit process in the four states that have commercial Class I wells."

Preliminary study of discharge characteristics of slim holes compared to production wells in liquid-dominated geothermal reservoirs (open access)

Preliminary study of discharge characteristics of slim holes compared to production wells in liquid-dominated geothermal reservoirs

There is current interest in using slim holes for geothermal exploration and reservoir assessment. A major question that must be addressed is whether results from flow or injection testing of slim holes can be scaled to predict large diameter production well performance. This brief report describes a preliminary examination of this question from a purely theoretical point of view. The WELBOR computer program was used to perform a series of calculations of the steady flow of fluid up geothermal boreholes of various diameters at various discharge rates. Starting with prescribed bottomhole conditions (pressure, enthalpy), the WELBOR code integrates the equations expressing conservation of mass, momentum and energy (together with fluid constitutive properties obtained from the steam tables) upwards towards the wellhead using numerical techniques. This results in computed profiles of conditions (pressure, temperature, steam volume fraction, etc.) as functions of depth within the flowing well, and also in a forecast of wellhead conditions (pressure, temperature, enthalpy, etc.). From these results, scaling rules are developed and discussed.

TREATMENT OF HYDROCARBON, ORGANIC RESIDUE AND PRODUCTION CHEMICAL DAMAGE MECHANISMS THROUGH THE APPLICATION OF CARBON DIOXIDE IN NATURAL GAS STORAGE WELLS (open access)

TREATMENT OF HYDROCARBON, ORGANIC RESIDUE AND PRODUCTION CHEMICAL DAMAGE MECHANISMS THROUGH THE APPLICATION OF CARBON DIOXIDE IN NATURAL GAS STORAGE WELLS

Two gas storage fields were studied for this project. Overisel field, operated by Consumer's Energy, is located near the town of Holland, Michigan. Huntsman Storage Unit, operated by Kinder Morgan, is located in Cheyenne County, Nebraska near the town of Sidney. Wells in both fields experienced declining performance over several years of their annual injection/production cycle. In both fields, the presence of hydrocarbons, organic materials or production chemicals was suspected as the cause of progressive formation damage leading to the performance decline. Core specimens and several material samples were collected from these two natural gas storage reservoirs. Laboratory studies were performed to characterize the samples that were believed to be representative of a reservoir damage mechanism previously identified as arising from the presence of hydrocarbons, organic residues or production chemicals. A series of laboratory experiments were performed to identify the sample materials, use these materials to damage the flow capacity of the core specimens and then attempt to remove or reduce the induced damage using either carbon dioxide or a mixture of carbon dioxide and other chemicals. Results of the experiments showed that pure carbon dioxide was effective in restoring flow capacity to the core specimens in several different settings. …
