Some of the most important aspects to consider during the design, construction and productive life of a well are the amount and nature of the risks associated with the conveyance of downhole instruments to acquire critical formation evaluation (FE) data while the hole is open and downhole tool strings needed to service the well after installing the completion and production hardware.

With the increase in popularity of long, deep and tortuous wells, mainly in the high-cost operating environments, these risks have become more acute.

A new methodology, based on forces modeling and best practices gathered over decades, has been developed to take full advantage of new conveyance technologies intended to alleviate or eliminate these risks.

This paper describes the new conveyance risk-reduction technologies and their areas of applications, the newly developed risk management methodology and the economical value these innovations bring to our industry.

To demonstrate the merits and practical aspects of such an enterprise, we discuss here the following case study:

  • A perforating job successfully completed using wireline and downhole tractors in a highly deviated well that was planned using the new methodology subject of this paper.
