Rio Blanco Massive Hydraulic Fracture: Project Definition

Description: The Piceance Basin in Colorado contains an estimated 600 trillion cu ft of natural gas in place. Both the Rulison and Rio Blanco events have been detonated to determine the feasibility of nuclear fracturing to stimulate natural gas production in this basin. A demonstration program to test the relative effectiveness of massive hydraulic fracturing (MHF) to achieve natural gas production stimulation from the same gas reservoir is presented. Details are included on MHF design parameters, including… more

In situ permeability measurements for the event in U1-C

Description: Test apparatus was designed for the measurement of the in situ permeability in the vicinity of the 1100-ft UI-C shaft at NTS. A very reasonable approximation to a one-dimensional flow geometry was obtined. Measurement of gas injection flow rates and pressures allowed the determination of the effective permeability of the medium around the Ul-C shaft to be from 1 to 10 darcys with the major exceptions at depths of less than 200 ft where the permeability was greater than 40 darcys. However, perme… more

Electromagnetic pulse source characteristics experiment on an underground nuclear event

Description: From EMP technical meeting; Kirtland AFB, New Mexico, USA (25 Sep 1973). Under sponsorship of the Advanced Research Projects Agency, the Lawrence Livermore Laboratory conducted an EMP experiment in conjunction with an underground nuclear event. The purpose of the overall study of which this experiment was a part was to document the characteristics of EMP signals generated by various underground nuclear events to provide checks for theoretical models under development. A major goal was to establ… more

Project Rio Blanco spall measurements data report

Description: A major instrumentation program was undertaken for the Rio Blanco experiment using accelerometers and velocity gages buried at various depths below the ground surface and at various horizontal ranges from the emplacement well. The objective was to physically measure the depth and aerial extent of spall (tensile failure of the earth material). Data from each of the instrument stations is given, along with the appropriate integrated data for particle velocity and displacement or just displacement… more

Mechanical Properties of Blair Dolomite

Description: Pressure-volume, uniaxial stress loading to failure, uniaxial strain, and acoustic velocity determinations were made on Blair dolomite at confining pressures ranging to 3.5 GPa (Pa = Paschals where 10/sup 5/ Pa = 1 bar or 0.1 GPa = 1 kbar). The bulk modulus K, rapidly rises from an initial 10.4 GPa (at atmospheric pressure) to 102.0 GPa at 1 GPa pressure. At higher pressures, K remains essentially constant (110 GPa). The maximum volume change on loading is 3.9% at 3.5 GPa; the unloading closely… more

Seismic refraction exploration for engineering site investigations

Description: The theory and practice of using the refraction seismograph for shallow, subsurface investigations is summarized. This is 1ntended to be a guide to the application of the technique and not a comprehensive analysis of every aspect of the method. The fundamentals are presented and their use in time-intercept calculations and interpretations using delay times are discussed. The limitations of this exploration tool are discussed, and other applications of the equipment, such as uphole surveys, are … more

Strain seismometer data from the ALMENDRO event at NTS

Description: The ALMENDRO Event was conducted on Pahute Mesa at NTS, and was announced as an intermediate yield event (200 to 1000 kt). Strainmeter records were obtalned at three locations in Yucca Flat. One recording site was a triaxial station; the other two were two component stations. The station parameters and pertinent data relating to ALMENDRO are summarized in tabular form. (TFD)

PALLOT: a FORTRAN code that produces graphical representations of nuclear blackout effects along a reentry trajectory

Description: The PALLOT code was developed to simplify the assimilation of data relating to effects of nuclear blackout on particular reentry trajectories. This code operates in three modes: azimuth, elevation, and inline, In the azimuth and elevation modes, the PALLOT picture represents a family of trajectories that only vary, respectively, in approach azimuth and impact elevation angle. The incline mode depicts a set of reentry vehicles approaching on the same trajectory through a nuclear environment. The… more

Biological effects of underground nuclear testing on marine organisms. II. Observed effects of Amchitka Island, Alaska, tests on marine fauna

Description: >From conference on the environmental effects of explosives and explosions; White Oak, Maryland, USA (30 May 1973). The biological effects of the Longshot, Milrow, and Cannikin underground nuclear tests at Amchitka lsland, Alaska, on marine mammals, fishes, and birds are summarized. The biological effects observed were related to the water-borne shock waves produced by the explosions. (CH)

Nuclear in situ recovery of oil from oil shale

Description: A plan is presented for production of oil by retorting oil shale in situ after breaking it with underground nuclear explosives. Reserves of oil shale of thickness and grade suitable (greater than 20 gal/ton) for this process occur in the Piceance Creek Basin of Colorado, and are estimated to contain 640 billion barrels of oil in place. Cost projections indicate that this oil could be produced at a price ranging from 00 to 30 at the wellhead with a 20% rate of return on investment (discounted ca… more

BOTE model: an analytic approach to predicting ground motion phenomena resulting from underground nuclear explosions

Description: An analytical model (the BOTE model) based upon a superposition of the limiting forms for the outgoing stress wave (i.e., a strong shock at early times decaying to a simple acoustic wave at later times) is presented as a means to describe the groundmotion phenomena resulting from underground nuclear explosions. Taking into account the effects of both the porosity and the water content of the surrounding medium, the BOTE model provides good agreement with both calculated and experimental data fo… more

PONDER: a FORTRAN code that graphically represents nuclear blackout effects

Description: The PONDER Code (Pictures of Nuclear Device Effects from RANC), which has been used at Lawrence Livermore Laboratory for performing radar blackout analyses is described. PONDER is an executive routine in which the well-known radar blackout code RANC (Radar Absorption Noise and Clutter) is a major subroutine. y a nuclear burst and that cause sufficient absorption or refraction of a signal to make the radar system under study ineffective.

Biological effects of underground nuclear testing on marine organisms. I. Review of documented shock effects, discussion of mechanisms of damage, and predictions of Amchitka test effects

Description: From conference on the environmental effects of explosives and explosions; White Oak, Maryland, USA (30 May 1973). The potential mechanisms of biological damage to fish resulting from a nuclear-induced shock wave appear to involve mechanical damage from bottom acceleration and rockspall; the synergistic effect of compression to decompression producing the mechanical expansion of gas spaces within the organism; effects of cavitation; and possibly the alteration of blood constituents. The indirec… more

Project Drum Inlet: explosive excavation in saturated sand

Description: Seasonal storms during February of 1971 completely closed the Drum Inlet navigation channel through the Outer Banks off the North Carolina coast. This channel is highly useful to commercial and sport fishing industries in the Carteret County vicinity of North Carolina, and is vital to maintenance of the ecological balance in the inland Core Sound waters. To reopen Drum Inlet, an alignment about 2.1 miles south of the original location was selected. A contract dredge excavated a channel from the… more

Cost and feasibility of stimulating tight gas reservoirs with chemical explosives

Description: Long, continuous, cylindrical charges of high explosives are considered as alternatives to nuclear explosives or massive hydraulic fracturing for the stimulation of gas production in tight gas formations. The calculational method was that used previously for nuclear stimulation; it was verified by comparison of the calculated and observed gas production from Rulison. The calculations indicate that charges of high explosives 24 inches in diameter and 2000 feet in length (the height assumed for t… more
