Working Environment

The health, safety and environment concept also includes the working environment, which according to the Working Environment Act is a collective term for all factors in the work situation that can have an impact on the employees' physical and psychological health and welfare. The content of the concept is evident from Section 1-1 of the Working Environment Act. In addition to health safety, e.g. physical, chemical, biological and ergonomic factors, the concept also includes psychological impacts and welfare factors. The most important working environment factors are mentioned in Chapter 4 of the Working Environment Act, see especially Section 4-1 of the Working Environment Act, which sets a requirement for a fully prudent working environment. For a more detailed discussion of this requirement, reference is made to Odelsting Proposition No. 3 (1975-1976), Recommendation to the Odelsting No. 10 (1976-1977) and Odelsting Proposition No. 49 (2004-2005).

Workover

“Workover” means a procedure the operator undertakes that is intended to increase production but is not routine maintenance and includes:
  1. re-entry into the well to drill deeper, to sidetrack to a different location, to recomplete for production or to restore production from a zone that has been temporarily abandoned;
  2. recompletion by re-perforation of a zone from which gas or oil has been produced or by perforation of a different zone;
  3. repair or replacement of faulty or damaged casing or related downhole equipment;
  4. fracturing, acidizing or installing compression equipment; or
