Permeability damage to natural fractures caused by fracturing fluid polymers

Description: Formation damage studies using artificially fractured, low-permeability sandstone cores indicate that viscosified fracturing fluids can severely restrict gas flow through these types of narrow fractures. These studies were performed in support of the Department of Energy's Multiwell Experiment (MWX). Extensive geological and production evaluations at the MWX site indicate that the presence of a natural fracture system is largely responsible for unstimulated gas production. The laboratory format… more

Eastern Gas Shales Program. Completion and stimulation of five New York State Energy Research and Development Authority Wells Allegany and Cattaraugus Counties, New York

Description: In order to evaluate the potential of the Devonian Shales as a source of natural gas, DOE/METC in Morgantown, West Virginia, has undertaken the Eastern Gas Shale Program (EGSP); not only to characterize and identify the resource, but also to enhance and improve the productivity of wells completed in the shale. One of the methods used to achieve improved productivity is hydraulic fracturing and, more specifically, foam fracturing. The efforts by DOE/METC included completion and stimulation of fi… more

Initial results from the first Los Alamos hot dry rock energy system

Description: The pressurized-water loop for extraction of natural heat from dry crustal rock is, as this is written, eight weeks into its initial long-term continuous circulation test. During most of this time, flow-impedance through the man-made fracture system has decreased continuously so that, with a nearly constant pressure difference between injection and recovery wells, flow rate has increased steadily to the maximum capacity of the surface piping--about 16 liters per second. Temperature of water ent… more

Horizontal drilling in shallow reservoirs

Description: The objectives of this joint horizontal drilling effort by the US DOE and Belden Blake in the complex, low permeability Clinton Sandstone will focus on the following objectives: (1) apply horizontal drilling technology in hard, abrasive, and tight Clinton Sandstone; (2) evaluate effects of multiple hydraulic fracturing in a low permeability horizontal wellbore; (3) assess economic viability of horizontal drilling in the Clinton and similar tight gas sands.

Hot dry rock, an alternate geothermal energy resource: a challenge for instrumentation

Description: The natural internal heat from the Earth is one of the cleanest, nearly inexhaustible energy sources. The hot dry rock that composes most of the Earth's crust has the potential of becoming one of the largest reservoirs of energy economically available in the near future. The Los Alamos Scientific Laboratory, for the past five years, has been working toward exploiting this very abundant, clean energy source. The LASL technique to demonstrate the technical and economic feasibility of extracting h… more

Hot dry rock Phase II reservoir engineering

Description: Early attempts to hydraulically fracture and connect two wells drilled at the Hot Dry Rock site at Fenton Hill in New Mexico failed. Microearthquakes triggered by hydraulic fracturing indicated that the fracture zones grew in unexpected directions. Consequently one of the wells was sidetracked at a depth of 2.9 km; was redrilled into the zones of most intense microseismic activity; and a flow connection was achieved. Hydraulic communication was improved by supplemental fracturing using recently… more

Stimulation model for lenticular sands: Volume 2, Users manual

Description: This User's Manual contains information for four fracture/proppant models. TUPROP1 contains a Geertsma and de Klerk type fracture model. The section of the program utilizing the proppant fracture geometry data from the pseudo three-dimensional highly elongated fracture model is called TUPROPC. The analogous proppant section of the program that was modified to accept fracture shape data from SA3DFRAC is called TUPROPS. TUPROPS also includes fracture closure. Finally there is the penny fracture a… more

Massive hydraulic fracturing well, Federal No. 498-4-1, Rio Blanco County, Colorado. Final report

Description: This project is an MHF of a previously untreated Mesaverde interval in a well in northwest Colorado. The rocks involved may have been deposited during a marine invasion of long-continued, swamp environments. If so, they would have possessed superior primary reservoir properties. The logging program, identical to those used in the nearby Rio Blanco Nuclear and MHF Project wells, supplied contradictory information. The frac could furnish better understanding of the log suite, better parameters fo… more

Anomalous fracture-extension pressure in granitic rocks

Description: Fracture-extension pressures appreciably higher than the least principal earth-stress were observed in hydraulic fractures formed in a pair of 3 km (9600 ft) deep boreholes drilled near the Valles Caldera in northern New Mexico. Pressurization of open wellbores in rock containing preexisting fractures may open these fractures, instead of creating new fractures at right angles to the least principal stress. The pressure necessary to flow into these fractures may be appreciably higher than the le… more

Vertical borehole design and completion practices used to remove methane gas from mineable coalbeds

Description: Coalbed gas drainage from the surface in advance of mining has long been the goal of researchers in mine safety. Bureau of Mines efforts to achieve this goal started about 1965 with the initiation of an applied research program designed to test drilling, completion, and production techniques for vertical boreholes. Under this program, over 100 boreholes were completed in 16 different coalbeds. The field methods derived from these tests, together with a basic understanding of the coalbed reservo… more

Hydrogeologic effects of natural disruptive events on nuclear waste repositories

Description: Some possible hydrogeologic effects of disruptive events that may affect repositories for nuclear wastte are described. A very large number of combinations of natural events can be imagined, but only those events which are judged to be most probable are covered. Waste-induced effects are not considered. The disruptive events discussed above are placed into four geologic settings. Although the geology is not specific to given repository sites that have been considered by other agencies, the geol… more

True in-situ bed preparation: oil shale and tar sand

Description: In 1978, a detailed study was conducted to evaluate the status of the bed preparation technology that had been developed for true in-situ processing of oil shale. It was concluded that the two techniques which had received the bulk of the attention in prior field experimentation, namely the wellbore springing and hydraulic/explosive fracturing concepts, both had inherent traits which would prevent them from being useful in practical applications. In the current paper, the previous results are r… more
