OMG regional geological characteristics
CASE: OMG Field in SE Asia

Because OMG oilfield rely on natural depletion long-term, recovery
degree is 20.65%, at present the Formation energy shortfall is serious, the
energy yield is low, it is necessary to combine the factors such as structure,
sandstone development condition, drilling horizon of the wells, the
condition of oil well output and so on to optimize well group in water
injection site testing to analyze the feasibility of waterflooding, which can
provide the basis for the field of large-scale water flooding adjustment
Test area selection and structural
characteristics

Test area selection is mainly based on the following principles:
① located in the oil production center, closer to the terminal, convenient
for management, and convenient for tracking the effect;
② there is no floor production equipment on well site and it is
advantageous for the construction;
③ the connecting condition with oil well is relatively good;
④ has the water injection conditions;
⑤. Consider the utilization condition of 3 Wells which were drilled in 2016;
⑥. Select OM-1, OM-3, OM-5 layer to inject.
