20090126994 | Method And System For Controlling Force In A Down-Hole Drilling Operation - A method and system of subterranean excavating that estimates a buoyancy force applied to a downhole excavating system from drilling fluid. The estimated buoyancy force is used to derive a true weight on bit (WOB) at the borehole bottom. The derived realized WOB is compared to a target WOB to obtain a change in WOB. Based on the change in WOB, the excavating system is adjusted so the realized WOB approximates the target WOB. The excavating system adjustment includes applying a compensating force to the string. Compensating forces can be produced by manipulating a block assembly or deploying a thruster device in the string. | 05-21-2009 |

20120174056 | CALCULATING MIGRATION POINTS FOR APPLICATION MIGRATION - Embodiments of the present invention relate to “migration points” and an associated method and calculation tool. In general, a migration point is a number that represents an evaluation of the size and complexity of performing a migration, port, or refresh of an application from a legacy platform to a new target platform. When migration points are applied to applications across a portfolio, the migration points provide a relative measurement of the size and complexity necessary to perform the migration. Additionally, this measurement can be used to make a determination in calculating migration productivity (i.e., migration points divided by person-months, similar to how software productivity utilizes function points). In a typical embodiment, the migration point total is based on a set of qualitative migration points and a set of quantitative migration points, which are based on various technical aspects of the application, operating system, and hardware involved with the migration process. | 07-05-2012 |
