SafeKick (SK)

SafeKick (SK) is pleased to present a proposal for the implementation of our SafeVision® Monitoring and Simulation System, including the Standalone, Office and Rig Packages, which has a flexible design where modules can be added to meet specific operational needs. The overall system is designed to be used from top to bottom, on all the sections of the well after the BOP is in place, improving the economics and safety of the entire well construction operation. In the end it is a complete Drilling Optimization and Safety Package.

The package is composed of the following :

  • Servers to run SafeVision on the rig in real-time, providing simulation in real-time, forward simulation and advanced monitoring and detection of problems.
  • SafeVision rig package software providing simulation in real-time, forward simulation and advanced monitoring and detection of problems.
  • SafeVision office package providing the same features as the Rig Package, simulation in real-time, forward simulation and advanced monitoring and detection of problems.
  • SafeVision Standalone Version.
SafeVision can be used to optimize all operations during well construction, such as:
  • Define maximum tripping speed to prevent surge and swab effects;
  • Define maximum speed for running casing and liner;
  • Define optimum flow rate, densities and height of cementing jobs;
  • Confirm flow rate is adequate to clean the well;
  • Confirm kick tolerance is within adequate levels;
  • During a well  control  event  the system helps  define the kill  mud weight  and the max circulation rate allowable, using  the  forward simulation tool confirming  there  will be  no negative effect to the well;
  • Confirm drilling is conducted within the safe mud weight window at all times;
  • Detection of kicks using pit volume, during drilling and during connections;
  • All the above conditions are monitored in real time also, confirming the predictions made with the Standalone of Forward Simulation tools;
One of the advantages of the system is to help the rig crew monitor the well the same way under all operations to be conducted, whether conventional drilling with an open to atmosphere well, MPD or during a well control event.
A.1 SafeVision® Rig Package – Monitoring Module
This module requires just computers on the rig, accessing data directly from the rig sensors or the rig data network. (Fig 1) shows the schematic of the additional equipment necessary and possible rig up and connection. The final installation configuration depend on the rig and how the data is available the safevision screen can be visualized on several locations on the rig, to those with authority to login, in additional to the driller (Fig 2).

The Monitoring Module makes the following features available to the user on the rig:
a) Conventional drilling
  • A visual display with the wellbore sketch, visualization of the pressure profile inside the wellbore relative to the pore and fracture pressures and any variable plotted as a function of time;
  • The same display available to anybody with authority on the rig as well as onshore;
  • A fully transient hydraulic model taking into account pressure and temperature effects on the mud properties, pipe rotation, pipe movement and cuttings load;
  • Comparison of actual vs. modeled variables (standpipe pressure, Bit ECD and hook load) allowing quick identification of potential problems developing in the well;
  • Easy to use forward simulation feature, using the current condition of the well in real time, without need for the user to input any data;
  • Kick/loss detection based on pit level;
  • Kick tolerance and trip margin automatically calculated and displayed at all times;
  • Covers all operations, including drilling, tripping, running and cementing casings/liners, etc.
b) With BOP Closed
  • Monitor leak-off test, BOP test and Casing Test, with the full pressure curve vs. time;
  • Monitor the entire Well Control Operation when an influx is detected, with a dedicated tab to visualize the choke and standpipe pressures, flow rate and pit level as a function of time, allowing a remote user to understand the actual situation and provide assistance to the rig if needed;
  • Monitor Negative Pressure Test and Choke Drills;
  • A fully transient hydraulic model taking into account pressure and temperature effects on the mud properties, pipe rotation, pipe movement, cuttings load, choke pressure and all actual rig well control lines, from the BOP all the way to the choke manifold, for more accurate simulation;
  • A visual display with the wellbore sketch, visualization of the pressure profile inside the wellbore relative to the pore and fracture pressures and any variable plotted as a function of time;
  • The same display available to anybody with authority on the rig as well as onshore.
