Completion design optimization of multilateral well to maximize hydrocarbon production in a bottom water drive reservoir
Manish Kumar,  Dr. Pushpa Sharma,  Dr. D K Gupta
Maximum reservoir contact (MRC) can help increase reserves recovery from the reservoir by many folds. It can lead to effective reservoir drainage, effective sweep and delayed coning and cusping. MRC can achieved using horizontal wells, multilateral wells and extended reach drilling (ERD). However, the long horizontal wellbore can pose some serious production problems. Higher pressure drawdown around the heel of the well can cause non-uniform fluid influx along the wellbore and higher production rates at the heel. This can lead to early breakthrough of water or gas.
Early Water breakthrough in Horizontal well completion in a bottom water drive reservoir is major issue which needs to be addressed in detail using available technical knowledge, previous experience and modern techniques.
The prime reason behind this is inability to model the pressure gradients that exist from the heel to toe in the horizontal part of the wellbore which can lead to inaccurate estimates of water breakthrough time and rate. In a heterogeneous reservoir, water and gas breakthrough can be delayed using inflow control devices which regulates flow from the reservoir into the wellbore.
This paper focuses on the:-
1. Development of three dimensional Geological model and validating it using history matching.
2. Use of well segmentation concept to compute frictional and acceleration losses in the horizontal section of the wellbore and assess its impact on well production.
3. Estimate the incremental oil production using inflow control devices in a multilateral well.
Outcome of the study:
1. ICD installation in horizontal wells can significantly increase the cumulative oil production and reduce water production.
