COIL" <br /> PETROLEUM SERVICES <br /> Ms Linda Schneider October 22, 1998 <br />' Sequoia Analytical <br /> 819 Striker Ave #8 <br /> Sacramento, CA 95834 <br /> Subject Transmittal of Geotechnical Analysis Data <br /> SA Work order# S810088-01 <br />' Core Lab File No 57111-98281 <br /> Dear Ms Schneider <br />' One soil sample was submitted to our Bakersfield laboratory for geotechnical. analysis <br /> Determinations of permeability to air, bulk density ,total porosity, fluid saturation, particle-size <br />' distribution and hydraulic conductivity were requested Measurement and calculation of air <br /> permeability, porosity, saturations and bulk density were performed as described in API RP-40, <br />' API Recommended Practice for Core-Analysis Procedure, 1960 Particle-size distribution was <br /> determined using a combination of ASTM D-422 (>850pm) and ASTM D-4464 (<850pm) <br /> methods Hydraulic conductivity's were determined using flex-wall permeameter methods as <br /> described in ASTM D-5084 Permeability to air determinations were made by steady-state <br /> methods with a confining pressure of 200 psi Grain and pore volume values used for porosity <br /> and density determinations were measured by Boyles Law double-cell methods utilizing an <br />' extended range helium porosimeter Moisture content was also determined using ASTM D-2216 <br /> standard methods Particle-size distribution was determined using standard sieves in combination <br /> with laser diffraction techniques As mentioned previously, a flex-wall permeameter was utilized <br /> ' for hydraulic conductivity measurements <br /> Accompanying this letter please find the results of this study We appreciate flus opportunity to <br /> ' be of service to you and to Sequoia Analytical Should you have any questions, or if we may be <br /> of further help in the future, please do not hesitate to contact us <br /> ' Very truly yours, <br /> r <br /> &ryupervisor <br /> ab -Rock Properties <br /> 3 <br /> JLS nw <br /> 1 original report, 1 cc report Addressee <br /> Core Laboratories,Inc <br /> 3430 Unicorn Road Bakersfield California 93308 (805)392-8600 Fax(805)392-0824 <br />
