The REYNA & SAB Oil Company from Mkotokuyana has been given a license by Tanzania Petroleum
development cooperation to explore and extract hydrocarbon in MKOMA onshore block 3. In order to complete
their mission in time with reasonable cost they employed group 07 member of petroleum geoscientist of third
year at Mineral resource institute for planning and scheduling the project.
The project involves the certain activities which are as it explained in the table below
Activity Duration
1 Geochemistry method 5
2 Seismic method 2
3 Magnetic and gravity method 3
4 Geochemistry data analysis 2
5 Seismic data analysis 2
6 Gravity and magnetic data analysis 3
7 Drilling 5
8 Reservoir modelling and estimation 10

(ii) Time for path B,E,G,H = 2+ 2+ 5+ 10 = 19 Days
(iii) Time for path C,F,G,H = 3+3+5+10 = 21 Days ( this is only critical path for the project)
The critical path for the said project is C,F,G,H identified by thick dark arrow with a minimum project duration of
21 days. Generally the table summarize the critical and non –critical activities of the project;
