Introduction The Crude oil storage project has its Site Investigation program split in two phases: Initial Site Investigation (SI) campaign in 1999 -2000 during the Detailed Feasibility Study. Supplementary Site Investigation (SSI) campaign in April – June’2007 during Tender Engineering.
1.1Initial Site Investigation (SI) The campaign was carried out by Engineers India Ltd with Skanska International Civil Engineering AB (as EIL’s foreign back up consultant) for the purpose of DFR level study. Items covered during this campaign are as below: i. Core Drilling: Six bore holes CH 1 to CH 6 were core drilled and executed by Fugro - KND Geotech Ltd. All the core drills were logged and documented. ii. Water Pressure Tests: All the core holes were tested with double packer water pressure tests and documented. iii. Seismic Refraction Study: Six seismic lines (S1 to S6) were aligned in grid pattern for study of rock mass; result has been interpreted and documented. iv. In Situ stress measurement: In situ stress was measured at the approximate cavern depth using hydrofracture method. v. Cross hole seismic tests: The locations for the investigation are shown in Drawing No. 1801.
1.2Supplementary Site Investigation (SSI)
ra02e 2005-01-17
The aim for this investigation was to acquire geotechnical data for the specific project locations and also to recheck the data as obtained in SI. Items covered are as below: i. Core drilling: four core drilling and logging fro CH P, CH Q, CH R and CH S ii. Water Pressure Testing: in the core holes all through the depth

Project 2158005;
iii. Seismic Refraction Study done on the valley at the SE corner of the facility AND Electrical Resistivity study along the lines of seismic study iv. Laboratory tests on rock core samples : a. Physical properties, compressive strength, triaxial strength, b. Chemical tests of water samples c. Drillability Tests to determine Drilling Rate Index (DRI) and Bit wear Index (BWI) All the tests and investigation except those for Drillability Tests are done through Rites Ltd. Drillability Tests are carried out at ‘Rock and Soil Mechanics’ laboratory of ‘SINTEF Building & Infrastructure’, NORWAY. The locations for the investigation are shown in Drawing No. 1801 & 1802.

Objective and Scope The purpose of this report is to present data that has been collected during the two site investigation campaigns. The report is limited to factual data as found during the testing at site. For interpretations of the data, reference is made to the Geotechnical Reference Conditions (GRC) and the Basic Engineering Design (BED) document. The data contained in this Geotechnical Factual Report are as obtained from the site. The data are supplied to the bidders for the purpose of understanding the geotechnical parameters & geological set up of the project area. The Owner emphasises that these factual data may be incomplete, incorrect and involve contradictions. The bidders shall for this reason be responsible for checking up the data before using it for the purpose of quotation and Client shall not be held responsible for the correctness, variation or deficiencies.
