EVALUATION AND DEVELOPMENT OF GEOHYDROLOGICAL SURVEYING METHODS IN AREAS WITH SALING GROUNDWATER

Objective

BOTH DEEP AND SHALLOW SEDIMENTS HAVE BEEN EXPLORES BY OIL AND WATER COMPANIES RESPECTIVELY. A LACK OF THE KNOWLEDGE OF GEOHYDROLOGICAL PARAMETERS AND LIMITED RESEARCH EXPERIENCE EXIST WITH RESPECT TO OLIGOCENE, EOCENE AND UPPER CRETACEONS SEDIMENTS IN THE SUBSURFACE OF THE NETHERLANDS.

THE AIM OF THE PROJECT IS:
- TO INVESTIGATE, EVALUATE AND TO INDICATE NECESSARY DEVELOPMENTS OF IN-SITU MEASUREMENT SYSTEMS AND METHODS OF GEOHYDROLOGICAL PARAMETERS IN BOREHOLES;
- TO GIVE RECOMMENDATIONS FOR THE SET-UP OF GEOHYDROLOGICAL BOREHOLES NEAR SALT STRUCTURES IN PHASE 2 OF THE DUTCH NUCLEAR WASTE DISPOSAL RESEARCH PROGRAMME;
- TO TEST AND COMPARE MEASUREMENT TECHNIQUES.

1.1. INVESTIGATION AND EVALUATION OF WELL TEST METHODS, THE POSSIBILITIES OF WIRELINE LOGGING, DOWNHOLE PH/EH MEASUREMENTS, ISOTOPE DATING TECHNIQUES AND SAMPLE METHODS OF BOTH UNDISTURBED UNCONSOLIDATED ROCK AND PORE WATER.

1.2. RECOMMENDATIONS FOR THE CONSTRUCTION OF BOREHOLES.

1.3. RECOMMENDATIONS FOR AN OPTIMIZED BOREHOLE AND SURVEY PROGRAMME.

2.1. SELECTION OF EXISTING DEEP BOREHOLES IN THE NETHERLANDS FOR WELL TESTS.

2.2. PERFORMING OF WELL TESTS AND SAMPLING OF FORMATIONS WATER.
EVALUATION OF THE RESULTS OF DIFFERENT METHODS AND COMPARISON WITH RESULTS FROM ANALYSES ON FORMATIONS SAMPLES.
