Hydrocarbon production is a complex and dynamic process lasting many years, during which huge volumes of fluids, with varying degrees of viscosity and corrosiveness, are set into motion.
DEVELOPING INCREASINGLY EFFECTIVE RECOVERY TECHNIQUES
For an oil or gas field to be profitable, it is crucial to maximize its production. This is why our teams at the CSTJF put all their efforts into developing the best possible recovery techniques. They do this by calculating well trajectories for optimal drainage of the reservoirs and by estimating the quantities of oil, gas and water produced by a field in its lifetime. Our experts draw on their knowledge of the geology of the area to predict, for each reservoir type, the behavior of the hydrocarbons during production, particularly their ability to flow into the well. In this way, they methodically appraise and neutralize any elements likely to clog or corrode the pipes and thereby hinder production.
Optimizing production and evaluating performance
Some of the major issues for field operations specialists include anticipating production decline, preventing the alteration of production facilities, extending the lifetime of our sites in optimal safety conditions, adapting recovery processes to each reservoir and studying the physico-chemical evolutions of the hydrocarbons produced during a field’s production life.
To enhance the productivity of our fields, the CSTJF has all the necessary resources to improve current techniques and design new ones. And it’s the affiliates of the Group’s Exploration & Production branch that benefit from them.
Our teams have developed new software programs that they have deployed in process control systems for oil and gas fields. These programs systematically optimize production in real time, 24/7, on all wells simultaneously.
And because we know how to anticipate, we are capable of installing made-to-measure pumps for the development of fields in the deep offshore. To prevent pressure drops for example, we use electric submersible pumps (ESP), and to manage excess quantities of associated gas and water, we make use of multiphase pumps (MPP) able to pump a mixture of liquids directly from the production stream rather than having to separate them first.
