Abstract
The Oil Industry is actively involved in screening new technologies to solve a common problem: to reduce capital expenditures as well as to minimise environmental impact.
Budget reduction has forced several Oil Companies to identify new solutions: for example, in onshore applications, slim hole drilling has been recently seen as a suitable tool for cost reduction in a variety of applications such as frontier basins and prospect evaluation, re-entries, production from marginal fields and so on.
An overview is presented on low cost drilling for marginal fields production in mature areas.
In relation to this particular scenario, appropriate technologies have been investigated with the above aim.
An innovative drilling rig, particularly tailored for marginal fields development, is presented in the paper along with the preliminary results of field applications.
