Hydrocarbon exploration in Brunei has resulted in sophisticated drilling projects highly dependent on integrated environments, real-time decisions, and top-class drilling engineering. During peak activity in 2011 and 2012, an operator faced a declining performance in well construction projects caused by wellrelated drilling issues in extended reach drilling (ERD), snake, fishhook wells, leading to an unnecessary increase of total well costs. Managing the previously mentioned risks to reduce nonproductive time (NPT) was the main driver for building an integrated environment for real-time decisions (IERTD), a new concept to optimize drilling operations by facilitating the decision-making process while maximizing the value of historical and realtime data. The preexisting real-time operation center was integrated into the operator's performance process where all workflows were redesigned to help ensure focus on cross-department value, risk mitigation and real-time interventions, instead of reporting and low-value interventions. Novel and innovative application of monitoring software technology helped align well teams to actual versus plan engineering models, helping ensure faster and reliable data analysis, providing teams better visibility of well status, allowing improved decision making.

Prospects below or near shallower producing fields can be economically attractive yet also risky since reservoir presence may be uncertain, reservoir quality can be poor, and high overpressure and temperature can make drilling and logging deeper prospects difficult. Systematic integration of relevant subsurface data from thin section to basin scale allows to seismically identify reservoir presence, and to predict reservoir quality for applicable rock types via burial histories. On an intermediate well log to seismic scale, a predictive rock physics modeling approach links reservoir and seal rock properties to seismic amplitude data to polarize the prospect's geologic ‘probability of success'. Particular challenges in the offshore Brunei study were very fine-grained deposits and non-vertical tectonic stresses associated with compressional settings. Both make porosity predictions that leverage complex burial histories rather than relying on extrapolated depth trends quite challenging - yet the integrated approach remains the best option to identify deep reservoir quality sweetspots that a favorable stress and temperature history may have preserved for certain reservoir rock types in certain locations.
The prolific petroleum system offshore Brunei features two major sediment fairways, the Baram and Champion river systems, and a variety of depositional environments, ranging from high NtG topsets inboard over shallow marine slope settings to deepwater turbidites outboard (
