Reliability databases
Reliability databases
One of ExproSoft’s main business area is design, development and maintenance of experience databases on equipment performance and operational practices within the upstream technology side of the petroleum industry – more precisely within drilling, completions and subsea production technology.
ExproSoft offers participation in the following databases – each representing ‘best in class’-performance in its respective area of application:
· WellMaster
· SubseaMaster
· Offshore Blowout Database
· Subsea BOP Master
Experience feedback within the petroleum industry is a challenging task, with achievement of co-ordinated feedback from a highly diversified group of oil companies and equipment manufacturers as perhaps the most difficult task. Roles are different, motivation is different and most companies are concerned about their competitive edge. But the effort pays off – for the benefit of an entire industry. The figure below illustrates the development in downhole safety valve (SCSSV/DHSV) performance over the past 20-25 years.

The figure shows the historical development of TR-SCSSV (tubing retrievable flapper valve type) reliability during the period 1983-2005, with sample data from ExproSoft and SINTEF reliability studies. Since early 2000, these activities have been carried forward by ExproSoft, following transfer of all commercial rights to the company from SINTEF as of April 2000. The documented improvement in reliability has lead to a significant improvement in installation safety levels and substantial cost savings for the funding oil companies through a reduction in intervention costs and higher availability of production/injection wells. Morever, legislators and governmental bodies in the petroleum exploitation worldwide are becoming increasingly aware of the benefits of quantitative risk assessments, adding further momentum to industry driven reliability database initiatives.
