Abstract: The present disclosure provides an impact simulation device and simulation method for characteristics of a rock chip bed in a large displacement well. The device comprises a wellbore system, a drilling fluid circulation system, a rock chip transportation system, a drill pipe control system, a data acquisition system, and a data processing system. The wellbore system is configured to simulate a horizontal annulus environment for rock chip transportation during drilling. The drilling fluid circulation system is configured to provide drilling fluid to the wellbore system and collect flow data of the drilling fluid. The rock chip transportation system is configured to simulate an output of rock chips in the horizontal annulus environment during drilling and recover the rock chips. The drill pipe control system is configured to implement drilling simulation in the wellbore system.

Abstract: Representative implementations provide devices and techniques for automatically generating a skeleton of at least a portion of a web service application. The skeleton comprises a framework that may be modified as needed for a desired use, such as for a relational database backed application, for example. In one aspect, the framework includes a versatile model to support different validation methods and varied customization. Filter support allows a user to perform actions on and/or define rules for inputs. In another aspect, the skeleton is automatically activated in an in-memory database repository.

Abstract: A framework for handling a wrapper procedure is provided herein. In accordance with one aspect, a user definition of a wrapper procedure encapsulating a stored procedure is received. The framework retrieves metadata associated with the stored procedure. The framework may prepare at least one query statement to invoke the stored procedure using an input parameter identified from the metadata. The framework may further set at least one value of at least one identified input parameter based on the metadata, and execute the prepared query statement using the set value of the input parameter to generate at least one value for an output parameter.
