Have you encountered difficulties setting a plug in a high deviation well?

If so, Peak can help.

We assisted a National Oil Company in Brunei set their 3-1/2" SIM Plug (nippleless plug) using mechanical slickline in order to isolate a failed inflow valve in a high devation gas well. The object of the exercise for the Customer was to evaluate the reservoir data as justification for future stimulation.

Three third-party formation isolation valves had previously failed and could not be used as a means of isolating the producing sands. The deeper deviated section of the well had also proved problematic in earlier well intervention operations, where the tubing crossover from 4-1/2" to 3-1/2" tubing was located.

Peak's solution provided many benefits to the Customer.

• This deployment highlighted the flexible nature of Peak SIM Plug and the fact it could be set at 69 degree deviation, given the correct toolstring configuration, which was critical for successful deployment
• Two 3-1/2" SIM Plugs were set using mechanical slickline, one just below the failed formation isolation valve valve and one just above. These two SIM Plugs allowed isolation of the producing sand. The upper SIM Plug was fitted with a downhole shut-in tool which allowed the sand to flow for a given period before the shut-in tool would close remotely, allowing a pressure build-up survey to be conducted
• The Customer was able to determine the flow characteristics of the sand and determine if it was worth future stimulation
• The use of a Jar Action Indicator Tool allowed the slickline operator to determine the performance of downward jarring at depth in this highly deviated well. This in turn allowed changes to be made to both the running toolstring and SIM Plug, to best meet the technical difficulties of setting a SIM Plug at 69 degrees on slickline.
