1. GR _sa = 20, GR _sh = 90

2. Calculate V _sh according to V _sh = (GR ? GR _sa)/(GR _sh ? GR _sa)

3. OWC at 646m

4. Assume a fluid density of 1.0g/cc in the water leg and 0.9 in the oil leg.

1. R _w = 0.02ohm

1. OWC at 646m

1. Zone	Top (m)	Base (m)	Gross (m)	Net (m)	Av. Por. (m)	S w
   Zone 1	616	622.5	6.5	0
   Zone 2 oil	622.5	646	23.5	21.5	0.108	0.509
   Zone 2 water	646	655.5	9.5	9.5	0.124	0.937
   Zone 3 water	655.5	675	19.5	1.52	0.05	0.767

2. Suggested stations for pretest measurements are:

   1. 624m reference density log

   2. 630

   3. 636

   4. 642

   5. 646

   6. 649

   7. 652.5

   8. 662

If the oil type is unknown, it is recommended to take a sample at 630m using a pump-out module to avoid contamination with WBM.

The following plot may be generated:

1. From this the FWL is picked at 646m. Note that because the sand is of reasonable quality no significant gap between the FWL and OWC would be expected. The oil density is 0.85g/cc. The water density is 1.02g/cc

2. Oil bearing

3. In order to avoid early water production it is recommended to use the tight streak at 638m to help avoid early water breakthrough. The following interval is therefore proposed: 622.5 638m (reference density log). The final evaluated logs should look like...
