Gravimetric monitoring of gas production from the Troll field
نویسنده
چکیده
Three surveys of relative gravity and depth measurements have been carried out over the Troll field during gas production. Due to several improvements in the methodology, precision (intra-survey repeatability measured as standard deviation) has improved from 26 μGal to 11 μGal and 4 μGal in the latest survey. This will improve the reliability of future monitoring, and also opens the range of applications to smaller and deeper fields.

Oil production optimization solved by piecewise linearization in a Branch & Price framework
This paper presents a method for optimizing oil production on large scale production networks such as the Troll west field in the North Sea. The method is based on piecewise linearization of all nonlinearities, and on decomposition of the full scale problem into smaller sub-problems. Column generation in a Branch & Price framework is used to solve the decomposed problem. The methods differs fro...

متن کاملSensitivity analysis of time lapse gravity for monitoring fluid saturation changes in a giant multi-phase gas reservoir located in south of Iran
The time lapse gravity method is a widely used technique to monitor the subsurface density changes in time and space. In hydrocarbon reservoirs, the density variations are due to different factors, such as: substitution of fluids with high density contrast, water influx, gas injection, and the variation in reservoir geomechanical behavior. Considering the monitoring of saturation changes in the...
متن کاملSimulation of Oil Reservoirs Driving Indices and Recovery Mechanisms
Different recovery mechanisms are activated during the production from reservoirs. Wells sometimes are kept with the injection. Therefore the evaluation of injection indices depended on material injection, seems to be necessary. This study is going to determine the drive indices for a reservoir by making a model using Eclipse. The model consists a gas cap and aquifer, in which there is an injec...
متن کاملDetermination of Time of Oil Cracking into Gas in Weiyuan Paleo-Oil Pool in Sichuan Basin, South China
Weiyuan gas field, located in the Sichuan basin of south China, is a large marine gas field with the oldest reservoir (the Sinian sequences) in south China. The hydrocarbon origin of the gas field has long been debated by petroleum geologists. Recently, it was recognized that a paleo-oil pool maybe the significant contributor to the gas field. Consequently, when the paleo-oil pool had been crac...
