Well Control Modeling Service - Kick Program

Well Control Modeling

Wild Well is the only company in the well control industry to provide a Well Control Modeling Service. Modeling is a very useful tool for supporting well plan evaluations and drilling operations. The software we use for modeling is the Kick program for simulating kick behavior. The Kick program is a complete time-transient, multiphase flow simulator that models full dynamic behavior of the well bore and its contents.

The Kick program simulates a kick from the time of influx through flow check, shut-in and subsequent kill operations. In comparison to other available software, this simulator allows changes in operating conditions to be made at any point during the well control process. In addition to standard kill methods, it can also model the full effects of special procedures, such as extending the shut-in of a kick and changing mud weight or pump rate during a kill and loss off circulation incident.

Kick Program Methods

The following Kick program methods illustrate just a few of the uses of this valuable tool.

Kick Circulation Modeling for Well Planning

  • Simulations generate circulating kick tolerances based on circulating out, not just shut-in, of well kicks over a range of magnitudes and sizes 
  • Casing shoe fracture pressure and surface gas handling equipment evaluated for their limits 
  • Specially trained personnel evaluate casing design and surface well control equipment using data from simulation 
  • Analysis performed for each section of the hole

Kick Circulation Modeling for Drilling Operations

  • Program creates individual sets of circulating kick tolerance charts for a specific combination of fracture gradient at casing shoe, mud weight range, casing setting depth and hole depth 
  • Charts updated on a regular basis as changes occur while drilling well 
  • Examples of such changes that alter kick tolerances:
    • Increases in mud weight
    • Unexpected results in shoe tests
    • Unexpected pore pressures
    • Change in casing points
    • Setting a contingency liner

Special Well Control Operations

  • Versatility of simulator allows modeling and evaluation of different well control procedures in addition to standard kill methods, including: 
    • Changing mud weight
    • Pump rate and other conditions during a kill
    • Changing choke, line and gas separator sizes
    • Extended shut-in before or during a kill
    • Volumetric kill to bleed gas to surface and maintain constant bottom hole pressure
    • Losing returns during a kill 
  • Other changes can be made to model special operations as needed to evaluate alternatives either during well planning or in response to actual well control situation.
