Case Study: Proactive Managed Pressure Drilling (MPD) by @balance Services Minimizes Fluid Losses and Avoids Deferred Production in Active Water-flooded Field in Colombia

Challenge:

  • Drill into a water-flooded field without shutting in injectors to maintain field dynamics and productivity
  • Avoid NPT due to kicks and losses common during conventional drilling
  • Minimize formation damage by using light drilling fluid

Solution: @balance Services implemented single- phase MPD techniques in three wells to evaluate benefits in this field. Surface backpressure was applied to the wells to control bottomhole pressure (BHP). A dedicated @balance Services MPD specialist and semi-automated MPD equipment were necessary to overcome drilling challenges.

Result:

  • @balance Services MPD proved to be the most efficient and safest technology to drill new wells in this brown field without affecting field productivity
  • Compared to conventional drilling, @balance Services MPD saved the client 100K USD per well
  • The use of light drilling fluid and the ability to control fluid losses created opportunities to increase well production due to low skin damage
  • The avoidance of well control incidents showed that this technology increases safety for drilling and completion operations

The complex interlaying sand structure and the nature of the water injection technique create numerous challenges when trying to conventionally drill these wells. Typically, more than six injector wells must be shut down several days in advance to minimize drilling problems, and they must remain shut down until drilling and completion is finished. Deferred production was identified as more than 4,000 bbls per well when drilled conventionally. Over the past few years, the client had tested various drilling techniques and technologies to eliminate the need to shut down injector wells while drilling new wells; however, they were never successful.
