Saving time and money
- Working with eDrilling, Maersk Training used its Live Well Support service to assist Wintershall with a drilling operation in the North Sea.
- Before drilling started, one particular part was highlighted as an extremely challenging section due to the harsh winter season, increased time exposure and other complicating factors that called for extra technical support.
- The initial start-up of Live Well Support aimed to ensure a proper test and tune phase in order to verify model simulations for further drilling operations. After that, hydraulic-simulations, risk analyses, and 3D visualisation of the wellbore were conducted on a daily basis.
- Throughout the project Maersk Training and eDrilling representatives participated in the operational meetings to advise and support the exploration department.
- The information obtained by Live Well Support was actively used to identify the limitations the team were working with, enabling fine-tuning of the mud weight strategy as pore pressure buildup started deeper and ended higher than predicted.
It was a regular Sunday afternoon for Just Sverre Wessel, testing a new drilling simulator that was to be used for training. The machine was monitoring the pressure, depth and possible complications in a modelled well, ready to be used on Maersk Training’s courses.
“We were testing and testing, and suddenly we thought, why don’t we use it for more than just training?” says Just, Operations Manager Oil & Gas for Oil & Gas at Maersk Training.
The result has been a new consultancy service called Live Well Support which, when it was tested with client Wintershall on a technically demanding drilling operation in the North Sea, saved 19 days drilling time – and total costs of about USD 19 million.
Modelling the well
The system was developed together with eDrilling, which provides drilling and well performance solutions, and built on data compiled by research company Sintef.
It works by modelling data to give an overview of the well to be drilled, including anticipated and modelled risks, so these can be taken into consideration before they are actually encountered. These could include a fault, potential limestone or pressure changes that may complicate the work.
