Adapting Extended-Reach, Float-In Tubular-Running Practices to SAGD Completions

Please join us on Wednesday May 25, 2016 where we will have a discussion on new adaptations in installing tubing in extended-reach laterals on Steam Assisted Gravity Drainage (SAGD) completion operations.

 

Brief: 

The difficulty of installing tubing in extended-reach laterals can be a limiting factor on Steam Assisted Gravity Drainage (SAGD) well completions, particularly when landing tubing at the toe of the well. Surface-applied force (tubing jacks) is often needed to land the tubing, introducing additional cost and the risk of helical buckling and plastic deformation. A method of running tubing in extended-reach horizontal wells is presented that uses floatation sub technology to reduce friction by adding buoyancy in the lateral section, thereby eliminating the requirement for tubing jacks. The new method applies the principles behind floating-in casing to SAGD tubing installation.

An extensive data set of running parameters for all the trials is shared. The float-in tubing trials are compared with both analog wells where conventional deployment methods (tubing jacks) were used, as well as with predicted torque-and-drag modeling.

In all trials of the float-in method, tubing was landed under its own weight, without using tubing jacks. In all of the analog conventional deployment trials, tubing jacks were required for the last 30–250m in order to successfully land tubing. Torque-and-drag models accurately predicted the point at which conventional tubing deployment loses running force and reaches static (neutral) weight.

In addition to eliminating the risk of helical buckling and plastic deformation caused by surface-applied compressive forces, the described method also lowers the probability of instrumentation failure, allows for easier short (dual) string deployment, and reduces tubing installation time and cost.
