Exploration is the initial and crucial step for many upstream operations in the Oil and Gas industry. A significant number of operations and processes take place during hydrocarbons exploration, among where some of the most sensitive include: drilling phase, a well-cementing, and a completion. During these processes, a range of highly complex physical phenomena are triggered and their evolution needs to be assessed and monitored by means of real time data. In some cases, the level of complexity of these phenomena may only be investigated through the use of numerical simulations.  Our background in computational simulation and software engineering allows us to develop tools which are able to manage large amounts of data, post-process it, and visualize relevant key results in order to support the evaluation of a possible, probable or proven reserve.

Offshore structures are generally considered as the starting point for mid-stream and upstream processes. As such, the simulation of both top-sides and substructures is one of the most critical aspects in the development process of offshore platforms mainly due to the harsh environmental and loading conditions that the structure must withstand. In general terms, offshore structures are subjected to waves, current forces, winds and earthquakes, which induce severe load combinations on the platform and could trigger catastrophic consequences. Past project experience allows us to contribute to the simulation of deck and submerged structures according to standard specifications and calculation methodologies typically utilized Offshore and Oil & Gas industry.
