TOTO August 4, 1969 Humble Oil and Refining Company Western Division 1800 Avenue of the Stars Los Angeles, California 90067 Attention: Mro Ro Hunt Gentlemen: Transmitted with this letter are four copies of our"Report, Soil Investigation, North Slope of Alaska°" The scope of work for this project was developed in discussions between representatives of Humble Oil and Refining Company, Esso Engineering and Research Company and Dames & Moore° Details of the planned scope are described in our proposal of May 7, 1969o The actual program under- taken up to this time was reduced at the request of Humble Oil and Refining Company° .We are pleased to have served you in connection with this project. If any questions arise concerning the information presented in this report, please feel free to contact us° Yours very truly, FER ED DAMES & MOORE Francis E o Ranft REPORT SOIL INVESTIGATION NORTH SLOPE OF ALASKA CONFIDENTIAL PROJECT AT-CL-1 HU~FER~I LA-HK-1 SEA-JL-1 SF-RDD-1 EO-2 NY~3 ~IVI§~ON OF C',t ~C;D %'~ 7371-003-10 REPORT SOIL INVESTIGATION NORTH SLOPE OF ALASKA ' IN TRODUC T I ON This report presents the results of a soil investigation on Reindeer Island located about ten miles north of the mouth of Prudhoe Bay in Alaska. The report describes one boring drilled and sampled under our supervision to apProximately 500 fact on Reindeer Island° Originally~ four borings were planned off the Arctic Coast in the vicinity of Prudhoe Bay, but the program was temporarily halted upon completion of the boring at Reindeer Island° Our work involved~ l) providing an experienced engineer and geologist for logging the boring and supervising the extraction of relatively undisturbed soil samples suitable for laboratory testing; 4) providing advice and guidance relating to drilling and sampling operations; providing equipment for obtaining rela- tively undisturbed soil samples; and establishing appropriate sampling intervals and the minimum penetration of the boring° No testing has been undertaken as yet° The soil samples obtained from the explorations will be held in our office in New York° DAMES P. MOORE Island No o 1, located at Latitude 70© 29' 12" North and Longitude i4¥© 20' 25" West° Reindeer .Island is approximately 1.4 miles long in an east-west direction and ranges up to approximately 300 or 400 feet wide° There is no vegetation on the island° The island is about three feet above sea level at the highest point° The surface soils consist of fine to medium sand and a moderate amount of gravel° The surface of the boring was at approximately Elevation +3 feet. This elevation was estimated using tide data. The Log of Boring is presented on Plate 1o Soils are described on the log according to the Unified Soil Classification System illustrated on Plate 2° Principally compact granular soils (sand and gravel) were penetrated in the boring° Significant quantities of gravel were encountered between the following depths 82 feet to 211 feet 223 feet to 245 feet 267 feet to 300 feet 473 feet to 509 feet Strata of relatively firm silt are present between depths of 35 to 56 feet and 245 to 268 feet° A number of lenses of woody material were encountered within the granular soils existing between 300 feet and 460 feet° The ground was frozen between depths of two feet to approximately 65 feet° The frozen soils above 15 feet contain large ice crys6also Between 15 feet and 65 feet smaller ice crystals were seen° It is believed that another f~ozen ~-i~xists between.300 feet and 420 feet? No ice crystals were observed° However, samples from this zone possessed moderate cohesion when extracted from the boring, but the DAMES P_. MOORE cohesion disappeared after the samples were exposed to above-freezing air temperature for several minutes° Most of the soils encountered possess good strength characteristic and are relatively incompressible° The silt samples obtained from the zones between 35 feet and 55 feet soften when they thaw° The frozen granular soils within a depth of 15 feet were observed to have significant amounts of ice crystais in the samples° These materials probably would weaken considerably if they were permitted to thaw° The effects of thawing on the frozen granular soils below a depth of 15 feet would be less significant° FIELD OPERATIONS Our personnel departed for the site during the week of June 16 and drilling began on June 21o Drilling and sampling activities requiring our participation terminated on July 2, 1969 when our personnel returned to their home offices° The boring was drilled with a DAMCO 2000° The boring was drilled open hole, using air, to a depth of 35 feet° There, caving prevented further penetration using this method° Thirteen and three-eighths-inch casing was set to 30 feet, and drilling continued using drilling mud° Upon reaching a depth of 90 feet, nine and five-eighths-inch pipe was placed and cemented. Because of caving at 125 feet, five-inch pipe was driven in one effort to 186 feet, where essential refusal was met using a 360=pound weight falling a distance of 35 inches° Below this depth, the boring was drilled without casing° DAMES P_.. MOORE Relatively undisturbed samples were obtained using a Dames & Moore sampler of the type illustrated on Plate 3o The sampler was driven using a 360-pound weight falling a distance of 35 inches. A double-tube core barrel was used at depths of five and ten feet to obtain samples of soil containing large amounts of ice° -o0o- FER: ed ¢c(4) .o The following Plates are attached and complete this Report: Plate 1 Plate 2 Plate 3 Log of Boring (Boring 1) Unified Soil Classification System Dames & Moore Soil Sampler Respectfully submitted, DAMES & MOORE Francis E o Ranft Mr. John Lyons Esso Research and Engineering Company Post Office Box 101 Florham Park~ New Jersey 07932 DAMES P_.
