چکیده

Oil well drilling is a complex process which frequently leads to operational problems. In order to deal with some of these problems, knowledge intensive case based reasoning (KiCBR) has clearly shown potential. An important problem in drilling is hole cleaning, in which a high number of observed parameters and other features are involved. This paper presents how to determine the root causes of poor hole cleaning episodes by means of KiCBR. The effect of general domain knowledge was demonstrated in a comparative study, in which improved results in terms of similarity assessment and explanation capability were achieved.

Comparing two types of knowledge-intensive CBR for optimized oil well drilling

This paper describes a new architecture for reasoning that combines case-based and model-based reasoning, referred to as knowledge intensive CBR (KiCBR). The case retrieval process is explained and compared through different reasoning approaches; plain CBR, and two forms of knowledgeintensive CBR. The mentioned methods are applied to problems in oil well drilling, a challenging domain. Knowledg...

Diagnosing Root Causes and Generating Graphical Explanations by Integrating Temporal Causal Reasoning and CBR

This study proposes a methodology to diagnose the root causes of failures in the domain of oil well drilling. The idea is to combine a Bayesian network, which is generated based on an expert knowledge, with situation-specific knowledge of past failure cases. A causal chain is viewed as a temporal sequence. To test the model’s capability, six failure cases from the study’s application domain (oi...

Transfer of experience for improved oil well drilling

The drilling process is getting increasingly more complex as oil fields mature and technology evolves. At the same time, the amount of information is increasing in volume and fr equency. Although technology is advancing, failures do occur, leading to loss of valuable time. When ever the process is running smoothly or is failing , valuable experience is gained . However, experience attrition is ...
