' r r r l r I f f l <'; " w ,, " K r APPENDIX C HYDRAULIC PRESSURE TEST DATA The basic dE~finition of the hydraulic pressure test, in terms of Lugeons, 1S a water takta of 1 litre/meter/minute at 10 bars pressure. Lugeon values for the current program were calculated using non-metric units in the following formula: Lugeon Value = 1820 x Rate of loss (gpm) Interval tested (ft.) x Net pressure (psi) Most of the calculations in the accompanying tabulation involved straight forward use of recorded data. There is some manipulation of data, however, particularly when incremental tests were performed. For example, consider a test conducted . 1n interval 189 ft. to 263 ft.' and a succeeding test conducted in the interval 159 ft. to 263 ft., the second test having a higher total water take. In this example a note would be recorded in the "Remarks" column of Table C-1 as "159-189", meaning that the water take from the shcrter interval has been subtracted from the large~ interval to better indicate the water take from 159 ft. to 189 ft. In some cases, similar to the above example, the water take of the lower test interval exceeded that of the higher interval. In this case, an asterisk ('!<) . the "Remarks" column appears 1n differential could that the water take of Table C-1. This indicates not be subtracted and for conservative estimating, the entire water take was used to calculate the Lugeon value of just the higher interval. Friction loss was not calculated in the standard manner, as losses in the HQ wireline rods were considered to be negligible. The pressure restrictions of the piping within the packer was considered . 1n the calculations, however, see Figure C-1. In all tests where water take rates exceeded 5 gpm, all pressure steps were calculated using a net applied pressure reduced 50592/C 840725 C-1 K !

The system consists of components that can be quickly assembled and disassembled in the field by a two man-crew, making it ideal for operations such as Watana that require helicopter transportation. With this system, borehole logs can be obtained to depths of 2700 feet. The components of the system are the instrument cabinet, winch assembly, boreholes probes, generator, radioactive sources, and support gear (electrical cables, power cord, tripod, etc.). The instrument cabinet mounts on top of the winch assembly, making all operating controls ~asily accessible to the operator. The instrument cabinet contains a digital recorder, digital printer and an analog strip~chart recorder~ The digital printout and analog recorder : :~vide hard copy that can be used "as is" for log analysis. and geologic interpretation. The digi.tal tape recorder provides a back-up means of storing data for later playback, manipulation, and printout using a compatible computer system. Three ~orehole proves were used during the 1984 Geotechnical Exploration Program: a combination probe capable of providing readout of resistance, spontaneous potential, and natural gamma activity; a density (gamma-gamma) probe containing a gamma-ray counter to which a Cesium 137 source was attached for each logging run; and a porosity (Neutron) probe containing a thermal neutron counter to which an Americium 241 Beryllium source was attached for each logging run. 50592/D 840725 D-1 \ l t. -----~--~~---------- The radioactive source for-the density (gamma-gamma) probe is a 5 millicure Cesium 137 load contained ~n a threaded subassembly that screw mounts directly to the lower end of the probe. \fuen not in use, the subassembly ~s locked in a carbon steel sheathed lead shield that also serves as an NRC app1:·oved shipping container. The radioactive source for the porosity (neutron) probe is a 1 curie Americium 241 Beryllium load contained in a threaded subassembly that also screw mounts directly to the lower end of its probe. When not in use, the AmBe subassembly is locked in a 14-inch diameter spherical shield constructed of cold-rolled, low-carbon steel filled with a Boron enriched, water-extended polyestero This shield also serves as an NRC approved shipping container. Operation and Data Acquisition Natural Gamma Survey The natural gamma survey was run first in each borehole for two purposes. The first purpose was to ensure that the borehole was in good cc~dition and open to the full survey depth prior to lowering a probe containing a radio- active source. The second was to obtain a log of the natural gamma radiation of the rock penetrated by the borehole. Gamma radiation originates in the spontaneous disintegration of atomic nuclei of various radioactive elements. The radiation intensity at any point in the borehole is directly related to the concentration and activity of the radioactive elements disseminated in the material surrounding the borehole. Variations in natural gamma radiation intensities in boreholes frequently can provide a method to correlate lithologies from borehole to borehole and/or can provide diagnostic data on lithologies and anomalies within a single bo·ehole. Initially, the probe was lowered in the borehole at 25-30 feet per minute ' ' and the instrument response was carefully monitored to determine the most effective scale(s) for recording the gamma log. The borehole was then 50592/D 840725 D-2 f~~f'- t I r ' logged from bottom to top at a speed of 10 feet per @inute, with the data being recorded in both analog and digital formats. Gamma-Gamma (Density) Survey The density survey was run in each borehole immediately after completion of the natural gamma logging run. The purpose of the density log was to obtain a profile of density variations along the borehole axis. The density detector 1s shielded from the Cesium 137 gamma photon source by Mallory-1000 metal. Gamma radiation is absorbed and/or scattered by all materials thro.ugh which it travels. The amount of radiation absorbed is directly proportional to the electro-n density of the material penetrated. The electron density is approximately propor~ional to the bulk density for most materials encountered during borehole geophysical surveys. The number of counts per second recorded by the detector is, therefore, inversely proportional to the bulk density of the material surrounding the density probe. The data from the density log can be used with other borehole logs, to characterize lithologic units, and to detect density changes within individual lithologic units related to weathering, joints, fracture zones, and chemical alteration. The most effective scale(s) for recording the density log was noted as the density probe was lowered into each borehole at 25-30 feet per minute. The boreholes were then logged from bottom to top at 10 feet per minute, with th~ data being recorded in analog and digital formats. Neutron (Porosity) Survey The porosity survey was run in each borehole (except DH 84-4) immediately after the completion of the density logging. Mechanical 1ifficulties precluded obtaining a porosity log for this bor~hole. The purpos~ of the porosity survey was to obtain a profile of porosity variations in the rock 50592/D 840725 D-3 r r,. r· f' ~I r' \( ;.4 \ ... ~ along each borehole axis. The porosity tool contains a neutron-thermal neutron, high energy source separated from a thermal neutron detector. High energy neutrons are introduced into the materials surrounding the borehole and the effect of the environment on the neutrons is measured. The most effective element in moderating neutron speed is hydrogen; therefore, a neutron probe responds most dramatically to the presence of water or hydrocarbons in the rock and soil surrounding a borehole. There are nu naturally occurr1ng concentrations of hydrocarbons in the sub- surface of the survey area, hence a decrease in the number of thermal neutrons pas~ing through the probe mounted detector indicates an 1ncrease 1n the amount of water (i.e. porosity) in the subsurface materials adjacent to the probe. The data from the porosity log can be used, along with other geophysical logs, to delineate lithologic units, and to detect porosity variations within individual lithologic units due to jo.:.nts, weathering, fracture zones, and chemical alteration. As in the other borehole surveys, the instrument response w~s monitored during the run do~\ the hole to select the most appropriate logging scale. The Porosity Probe was lowered at 25-30 feet per minute and then·logged from bottom to top at 10 feet per minute, with the data being recorded in analog and digital formats. Radiation Surveys Prior to and at the conclusion of borehole geophysical surveys that used radioactive sources, the well head and surrounding area were surveyed using a sensitive radiation detection device. Radiation surveys were also performed on the source/shield assemblies before and after each relocation. Both sources were directly tested for any leakage at the qqmpletion Qf each logging op~ration. 50592/D 840725 D-4 r - Interpretation Fractures and Joints Typically, individual fracture zones 1n the diorite at the Watana Site are expressed on the density logs of the coreholes as 200 to 500 cps (counts per second) spikes when logged through the HQ drill rods, and 400 to 1000 cps spikes when logged through the PVC casing. Fracture/joint frequency (lew density spikes) is variable from hole to hole, but tends to increase toward the surface as might be expected from rocks responding to glacial or erosional unloading. This decrease in fracture frequency with depth is best illustrated on the density log of DH 84-2, with very few fractures/joints indicated below 200 feet. There is good correlation between these low density log spikes, low neutron anomalies (higher hydrogen or water content.), and the presence of fractured rock seen 1n the drillcore. Depth to Bedrock There are no un1que diagnostic indicators for identifying top of bedrock on any of the geophysical logse Where bedrock surface was shallow, the most charateristic response was a lower neutron shift to the left (higher pvrosity) and lower density and gamma shifts to the right. Lithologic Correlation/Lithologic Response Correlation between boreholes is not always possible in crystalline rock, however, gross lithologic differences usually are discernable as in DH 84-1 where diorite and andesite prophyry are in contact. The andesite at thi& borehole has a natural gamma response at least twice that of diorite. The high gamma response of andesite is also supported by the high gamma "kick" at the 132-134 ft. interval of DH 84-9 where the borehole passed through an· andesite boulder near the base of the glacial till, and at 321 ft. in DH 84-4A where the borehole passed through a fine grained felsic dike. 50592/D 840725 D-5 I Clayey sand and dense till observed in the core of DH 84-4A 1n the 6 to 52 ft. interval correlates well with similar density and gamma responses 1n the 34-80 ft. interval of DH 84-4 and the 18 to 62 ft. interval of DH 84-10. Similarily, weat1:'qred diorite. in the 62-120 ft. section of DH 84-10 c..orrelates with weathered dio:rite in the 72-125 ft. section of DH 84-4A. Alteration Zones Hydrothermally altered diorite zones and healeci breccia ar.e ~sually matched on the density log by an anomaly that is lower in amplitude and broader ttan the low density spikes occurr1ng opposite fractures and joints (compare, for instance, the fracture response from 80 to 84 ft. in DH 84-8 to the altered diorite in DH 84-9 from approximately 308 to 318 ft.). Weathering One indicator of the depth of weathering as observed from examination of the core is the depth to which iron oxide staining persists in fracturing and jointing. Another is the condition or degree of kaolinization of feldspars, although other processes can cause kaolinization of feldspar. The point at which hard, strong,. fresh diorite is noted in the core equates on the density log to ~ 450 cps for those boreholes logged through the HQ drill rod; ! 700 cps when logged through plastic casing; and Boo· to 1000 cps when logged in open hole. Other Log Responses Not all geophysical log anomalies are caused by the rock formation being logged. The following log responses in boreholes at Watana need to be noted for more accurate log interpretation: a. 50592/D 840725 Logging beyond the end of the drill rod or PVC cas~ng (open hole) causes all three curves to shift to the right because of the decrease in signal atten.utation such as occurs at 690 ft. in DR 84-4A. D-6 I ' I b. Logging up through the water table into the unsaturated zone causes a shift to the right of all three curves because of the decrease in attenuation in air vs. water, such as in DH 84-7 at 79 ft. c. Different weight (wall thickness) drill rods affects the den- sity response as observed in DH 84-4A at~ 330 ft., 420 ft., 490 fta, 530 ft., and 670 ft., where l~ghter HCQ drill rods were used. In contrast, the higher density anomaly in the 308-316 ft. section of DH 84-4 is caused by logging through a section of a twisted-of£ core barrel. Similarily, the low density spike at 663.5 ft. in DH 84-2 is caused by an unscrewed drill rod. 50592/D 840725 D-7 r r .• J. i i ~ I : ... ~.J. I * .. l ! . ..· ·r . I ' .. . I , I l-. • l-~.

In addition to the details shown, some boreholes were instrumented with 2"ID PVC standpipe with a 5 or 10 foot long slotted sectiono The larger diameter standpipe enabled geophysical logging to be done later in the program. In several boreholes, a redundant type piezometer system was installed to enable year-round groundwater monitoring. The pneumatic piezometers are not su~ceptible to freezing during the winter months, which eliminates the need for an anti-freeze mixture in the standpipe piezometers. Shortly after installation all boreholes were purged with nitrogen for the purpose of ml.ni toring groundwater recharge and sampling the groundwater. '\ I I I I I· ·t I ' t 1 l ll 'I ·I .. 1, l• !

Table G-1 is a summary of the data according to lithology, considering weathering/alteration characteristics; just lithology; and for the total sample populationa In addition, under each of these c.ategories, the summary is organized to compare the total population with those samples which had no apparent planes of weakness. The results of the point load testing of all samples indicate a maan unconfined compressive strength of 15,315 psi with a standard deviation of + 7, 745 psi. S1,1bdividing the results into the two basic lithologies indicates a mean value of 19,617 psi for the andesite porphyry and 14,995 psi for the diorite suite. These values defined in unconfined compressive strength tests performed by Acres American (1982; andesite porphyry = 18,361 psi, diorite = 17 >593 psi). The results are in general agreeme:nt with previous work, and it is possible that the lower values for the diorite suite is in part due to the number of weathered/altered samplea tested. In classifying the rock material for strength, tests show the intact: rock to be of medium to high strength (Bieniawski, 1973). 50604 G-2 840726 ) J ' l .,.1 ,,. { I f ! i· I I ' ' ,-; ' l ~' I! i i r: 1 i I I • ~ ,, ! i -~ \ t I J ; ' I ' . --! .li II Q H I l 1- - : l ~ ' ; i ' { I ~ l ~ I ~ !
