The main focus of the eDrilling System is to provide real time supervision and decision support during drilling. It enables decision makers to have better insight into the status of the well and thus make better and quicker decisions. The eDrilling System is now being commercialized by the company eDrilling Solutions, partly owned by SINTEF Petroleum Research.
FORmation MEchanics Logging - FORMEL
The software uses input from wireline logs (acoustic velocities, density, porosity ++) to simulate standard rock mechanical strength tests on cores. The output is full stress-strain curves for a single depth or logs of rock strength parameters and stiffness versus depth.
Integrated Drilling Simulator (IDS)
The Integrated Drilling Simulator (IDS) is the heart of both the eDrilling System and the eControl System. IDS is a synthesis of multiple transient and steady state coupled models for the drilling sub-processes. It simulates interactions between the various sub-processes. At present the IDS consists of a dynamic flow and temperature model, a torque and drag model, a rate of penetration (ROP) model, a wellbore stability model, and a pore pressure model.
Palaeo-water depth reconstruction (SEMI PWD)
The SEMI Palaeo-Water Depth (PWD) module provides high resolution 3D palaeo-bathymetries for sedimentary basins. The method is based on present day stratigraphic depth maps as the main criterion for the PWD reconstruction. During the work-flow, different numeric modelling steps are combined including decompaction and compaction of stratigraphic units as well as the effect of isostatic compensation.
