“…This can involve the use of simple electronic crisis handling checklists (similar to the practices used by aircraft crew). In addition, more sophisticated methods, e.g., semantic decision tables or even offline trained classifiers based on the experience of a large amount of rig data (aggregating offline knowledge from multiple rigs and boreholes), might be feasible [3]. The following sub-sections explain each critical operation.…”

In sub-surface drilling rigs, one key critical crisis is unwanted influx into the borehole as a result of increasing the influx rate while drilling deeper into a high-pressure gas formation. Although established risk assessments in drilling rigs provide a high degree of protection, uncertainty arises due to the behavior of the formation being drilled into, which may cause crucial situations at the rig. To overcome such uncertainties, real-time sensor measurements are used to predict, and thus prevent, such crises. In addition, new understandings of the effective events were derived from raw data. In order to avoid the computational overhead of input feature analysis that hinders time-critical prediction, EventTracker sensitivity analysis, an incremental method that can support dimensionality reduction, was applied to real-world data from 1600 features per each of the 4 wells as input and 6 time series per each of the 4 wells as output. The resulting significant input series were then introduced to two classification methods: Random Forest Classifier and Neural Networks. Performance of the EventTracker method was understood correlated with a conventional manual method that incorporated expert knowledge. More importantly, the outcome of a Neural Network Classifier was improved by reducing the number of inputs according to the results of the EventTracker feature selection. Most important of all, the generation of results of the EventTracker method took fractions of milliseconds that left plenty of time before the next bunch of data samples.

Lessons on Corporate “Sustainability” Disclosure from Deepwater Horizon

The BP oil spill highlighted shortcomings of current financial and sustainability reporting standards and practice. "Integrated reporting" aims to combine financial and social/environmental information into a single annual corporate report. But without more stringent standards, integrated reports would neglect substantial risks and, as BP's sustainability reports demonstrate, create false impressions of good practice.To be of value, integration must: 1. Require timely disclosure of enforcement notices, orders and allegations issued by regulators. 2. Require disclosure of credible scientific reports and concerns indicative of potentially catastrophic risks of a company's products and activities, regardless of scientific uncertainty. 3. Require review and disclosures of a firm's safety culture. 4. Require disclosure of any facts or circumstances needed to ensure that the management's self-portrait of its sustainability strategies, goals and progress is not materially misleading.In conducting its misleading reporting, BP largely followed Global Reporting Initiative (GRI) guidelines. GRI is soliciting input, beginning in summer 2011, on how to revise those guidelines. Since GRI may prove a leading source for sustainability disclosure rules in integrating reporting, lessons learned from the BP experience must be applied to the next GRI revisions.
