SUMMARY

Velocity Data Pty Ltd conducted a velocity survey for Pancontinenta1 Petroleum PtyLtd in the Undandita No 1A well OP 179 Northern Territory The date of the survey was January 18 1983

The results of the survey which are considered to be reliable have been used to calibrate the sonic logs

Explosives were used as an energy source with shots being fired in the mUdpit The well was surveyed to a depth of 1201 metres below KB

Shots were recorded on digital cassette tape and later transcribed to a nine track tape (SEG-Y format) in Velocity Datas Brisbane centre Print-outs of the shots used are included with this report

The sampling rate was 1 ms with ~ ms sampling over a 200 ms window encompassing the first arrivals The scale of the graphic display varies with signal strength and is noted on each playout

Times were picked from playouts using the numerical value of the signal strength

NU - time long - poor fit to sonic curve

A replacement velocity of 3800 ms was used to correct to a 800 m datum which is above ground level The time correction of +011 1 seconds has been adjusted by -004 seconds for instrument lag giving a final correction of +007 1 seconds

COMPUTING

1 Method

Sonic times are adjusted to check-shot times using two methods

(a) A linear correction in ~secsmetre where check-shot interval times are longer than corresponding sonic times and errors are assumed to be instrumental

(b) A differential correction as a percentage change in the interval time where differences are assumed to arise from caving or mud cake effects or where formation characteristics such as high porosity or the presence of gas is suspected Additional points have been selected between shots where apparent velocity changes are noted on the sonic log

2 Results

Discrepancies between shot interval times and the corresponding sonic times are moderate to large the largest being 434 ~secsmetre over the 328-510 metre interval

In aggregate shot interval times are 015 6 secs shorter than the sonic times over the surveyed section of the well between 328 and 1155 metres below KB The large discrepancies may in some part be due to difficulties in hand digitising parts of the sonic log

The time lags noted on the surface well-head phone are probably due to ground fatigue around the shot location These lags have been subtracted from times where applicable to effect better ties where repeat shots were taken at a level and to conform more closely to the sonic curve These corrections are listed in this report
