Well construction usually makes up the highest cost of projects: therefore, during asset evaluation and acquisition, companies need to define how the reservoir can be reached, with how many wells, and the high-level overall cost and risks of the well construction phase. 

The project may be envisioned as a sequential well drilling effort, or with multiple rigs, or spread out over time based on reservoir evaluation and production purposes.  Most of the time, there are several scenarios to consider, all interlinked with one another, with different cost and risk implications.

Welltodrill has worked on feasibility studies in the North Sea, Italy, Kazakhstan, West Africa and Madagascar, for land, jack-up and drillship projects.

In this phase, close collaboration with the asset team (geologists, reservoir engineers, production engineers) is paramount to obtain a sound feasibility and time & cost estimate.
