4.0 DATA ANALYSIS

The results of the air-lift pumping test provides informationon static hydraulic head, hydraulic conductivity, and preliminaryhydrochemistry in the selected interval.

Static head is obtained prior to pumping and also followingthe constant rate air-lift test.

Transmissivity is determined by analyzing the drawdown (ifavailable) and the recovery portion of the air-lift pumping test usingthe straight-line method (Cooper and Jacob, 1946) and the modifiedTheis recovery method (Theis, 1935). Hydraulic-conductivity (K)is computed from the equation: K=T/m where T equals transmissivity,and m equals effective saturated thickness.

INSTANTANEOUS SLUG WITHDRAWAL/INJECTION TEST

1.0 INTRODUCTION

The instantaneous slug withdrawal and injection tests areconducted by inducing an instantaneous pressure reduction orincrease in hydraulic head within the tested zone followed byobservation of the associated hydraulic response. The purposeof these tests is to provide corraborative data on the hydrologiccharacteristics of the test interval. These tests are conductedafter all other hydrologic tests have been performed in the selectedhorizon. The procedures for conducting instantaneous slugwithdrawal/injection tests are described below in Section 3.0.

2.0 SAFETY

Safety requirements shall be in accordance with RHO-BWI-MA-4,BOP C-1.2, Section 4.0.

3.0 PROCEDURES

The procedures for conducting slug injection/withdrawal testsare described below.

3.1 EQUIPMENT

1. Packerelement(s) to isolate test interval.

2. Calibrated and sensitive pressure transducers and recordingequipment to monitor pressure changes.

3.2 METHOD

1. Allow the hydraulic head to reach equilibrium prior toconducting tests.

2. Instantaneously withdraw or inject a slug of known volumeto induce a pressure differential between the formation and.a fluid level in the tubing.

3. Monitor recovery pressure responses following instantaneousinjection or withdrawal.

3.3 RECORD OF MEASUREMENTS

1. General hydrologic information, equipment, and measurementdatum shall be recorded on EWIP Hydrologic Informationform, Figure 2.

2. Pressure measurements shall be monitored with calibratedand sensitive pressure transducers. These measurementsshall be noted on hydrologic form, Instantaneous SlugTest DataSheet, shown in Figure 7. Pressure transducermeasurements shall be verified in the field by takingmeasurements on a selected basis with a calibrated pressuregage or known atmospheric pressure reading.

4.0 DATA ANALYSIS

Slug/withdrawal testing data are obtained to determinetransmissivity using analytical solutions by Copper and Others(1967) and Van der Kamp (1976). The hydraulic conductivity (K)is computed from the empirical equation K- T/m; where T equals -

transmissivity, and m equals effective saturated thickness.
