Abstract: A distributed computing system and method is described herein. The system and method employ a server node, compute nodes, a network file system server providing shared data storage resources, and client systems. The server node receives and processes a document submitted by a client system. The document specifies a job including a number of compute tasks that are to be executed in a distributed manner by the compute nodes, data for at least one compute task of the job, a shared directory on the network file system server, and a collection of the compute nodes that have access to the shared directory. The server node stores the data for the compute task of the job into the shared directory. At least one compute node that belongs to the collection accesses the directory to process the data for the compute task of the job for execution of the compute task.

Abstract: LWD measurements to be used for proactive well placement while drilling a high angle or horizontal wellbore in a reservoir are defined. An initial reservoir model is provided and a section is extracted for a planned wellbore trajectory. A secondary model is generated for the planned trajectory. An area of interest is identified where statistical uncertainty is high. Possible causes of the statistical uncertainty are identified that are not present in the initial reservoir model. A set of parameters are defined based on the possible causes of statistical uncertainty. The area of interest is logged with LWD tool. Sensitivities of the LWD tool response to a subset of parameters are evaluated by performing tertiary model for a range of the subset of parameters. The most sensitive parameters from the subset of parameters and corresponding measurements are identified. LWD measurements are defined based on the most sensitive parameters.

Abstract: Methods for three-dimensionally characterizing a reservoir while drilling a high angle or horizontal wellbore through the reservoir are disclosed. An initial reservoir model for the reservoir is selected and a section is extracted for a planned trajectory of the wellbore. A secondary model is generated by performing secondary modeling for at least part of the planned trajectory. An area of interest is identified within the secondary model where statistical uncertainty is high. Possible causes of the statistical uncertainty are identified for the area of interest within the secondary model that are not present or accounted for in the initial reservoir model. A set of parameters for the area of interest are defined at that are based on the possible causes of statistical uncertainty. The area of interest is logged with at least one logging while drilling LWD tool.
