Transient cuttings transport model draws attention

26.11.2015

In a new project, addressing Statoil's guidelines for hole cleaning, a transient cuttings transport model initially developed in DrillWell, will be used.

Development of the model started in the project "ROP Management and Improvement" lead by Chief Scientist Eric Cayeux at IRIS.

The model has drawn attention both nationally and internationally because of its capability of predicting in real time the forming and degradation of cuttings bed and the transport of cuttings in suspension. Validation of the model against field data from several North Sea drilling operations show very good results.

Sufficient hole cleaning is of major importance during well drilling. The costs associated with circulation of cuttings adds up to several billions NOK each year. Estimates shows that up to 25% reduced time can be obtained by optimization of hole cleaning procedures.
-If our model can contribute to reduce circulation time when cleaning the well we have delivered a major contribution to reduce drilling costs, says Sigmund Stokka, Manager of DrillWell.

For more information about the model, see "Real-Time Evaluation of Hole Cleaning Conditions Using a Transient Cuttings Transport Model", by E. Cayeux, IRIS, T. Mesagan, S. Tanripada and M. Zidan, Statoil; K.K. Fjelde, University of Stavanger, 163492-PA SPE Drilling & Completion Journal Paper - 2014.
