Water Injection Subsurface Assessment for PETRONAS
EQ was privileged to complete the water injection (WI) subsurface assessment for selected WI fields for PETRONAS. The assessment focused on the WI management practices of well performance, reservoir performance and reservoir management compliance.
 |
The assessment of 44 WI reservoirs from nine fields has successfully identified some of good practices in WI management.
The tangible findings for these nine WI fields include:
- The total 2014 WI rate gap (actual against target) was about 70 kbw/d; further WI practices improvements in meeting injection targets are required in most of the fields;
|
 |
- 2014 WIM capacity utilization (actual maximum WI against WIM capacity) ranged from 11% to 90%; when combining with average WI utilization, possible additional WI rate / volume are in the range of 3% to 19%.
- The total 2014 oil rate gap (actual against target) was 32 kbo/d; further WI practices improvements in meeting oil production targets are required in most of the fields;
|
- The total reserves-at-risk estimated for 19 WI reservoirs was 32% of total assessed reservoirs from which 90% were attributed to the reservoirs of four major WI Fields.
- About 60% of the assessed reservoirs had reserves/production (R/P) of more than 10 years indicating possible inefficient depletion;
|
 |
About 60% of the assessed reservoirs had recovery factor (RF) of less than 45% indicating inadequate reservoir sweep.
