Production monitoring

CASE STUDY

 

Nadym-Pur West Siberia,
RussianFederation

 

Time lapse gravity surveys: 1998-2008

 

Problem:

  • Monitoring of water flooding in main gas pool - Cenomanian, Cretaceous, К1-2pk  (monitoring by seismic is impossible due to absence of seismic signal over the structure)
  • Study of more shallow reservoir in Upper Cretaceous - Berezov suit, Cenonian,  К2br

Results:

  • Pressure drop by 5-6 МPa and gas-saturation change after 10 years of production were identified in 4D+1D density model
  • Predicted location of gas water contact rise
