... will be made during the operation such as changes in mud weight and rheology. Finally, the actual possible drilling performance may be subject to unforeseen geological variations and unprecise formation rock strength characteristics. Equipped with this probabilistic environment, we can perform drilling...

... Abstract BP has a successful, limited scope deployment of a non-parametric capability called Event Detection and Association (EDA). The technology resembles ‘Market Basket Analysis’ tools used to carry out associative assessments of item sets. Variations from the original analytical approach...

.... The dominant problems for onshore time-lapse are caused by near-surface variations between base and monitor surveys [ Pevzner 2011 ]. By taking appropriate measures in acquisition and processing it is possible to overcome these problems. We demonstrate that with a continuous seismic time-lapse field trial...

The networked drillstring data could be used optimally, together with an advanced near well model, in order to quickly detect variations from the normal", such as open hole washout, cuttings loading...

... characteristics and fluids with high H 2 S concentration up to 16% (160,000 ppm). Difficulties were experienced with one of the main intelligent components of the surveillance systems, the Multiphase Flow Meter (MPFM), due to the H 2 S variations, which can reach up to 5% within the same reservoir. Qatif field...

... with varying densities. Conventionally, it is regarded to be problematic to track production variations in real time across the network back to the source wells. This is due to issues with metering multiphase flows and assumed uncertain transport delays. It is shown here that it is now practical to track...
