..., calibrated cost estimating tool combined with an efficient cost tracking program improves well planning, estimating accuracy and cost control. On a work load basis, these systems also increase productivity by reducing the time and effort required to review booked costs and produce drilling AFE's, thereby...

... to generate an automatic AFE that delivers automatically TvD curves for the different percentiles and it is aligned to the latest rig's performance and the well architecture. This tool will help the drilling engineers to estimate, quick and more accurate, the well duration time, especially when the rig...

DDS surveys offer much more efficient rig operations, improved borehole quality, trajectory control, and higher survey density than traditional stationary MWD surveys. The efficiency improvements DDS provides are a step-change in the drilling...

... logging, MWD and directional drilling cabin and any other service that will take some time to rig up. The rig up is treated as lumpsum in most cases so that such vendors can rig up and leave until their services will be required. Some of the tools to keep your eyes during execution, monitoring...

... ever- increasing rig rates and overall drilling costs, reentries are much more attractive and any time that can be saved from the project also means a lower AFE and shorter time to production. The natural extension of this milling and drilling ability is to extend the rathole as far as possible...

... for the latest drilling campaign. Ultimately, its application proved to reduce rig time, avoid NPT related to wellbore stability, eliminate the need of drilling mud in top hole by using sea water instead, reduce total AFE budget and guarantee casing would be set at the drilled depth. However, previous...

... approach, drilling efficiency has been increased significantly in a safe manner. As a result, 354 rig days have been saved (including drilling and completion only) which represent an improvement of 21.8% compared with the original AFE. Converted to sum, it was an 89.54 million USD reduction. In addition...
