How the simultaneous operations should be managed in an effective and compliant way when having drilling activities around?
What are the combinations to be considered, and how should they be managed well?
When is the time not to allow an operating activity along with the other?
SIMOPS Management - Drilling Activities
Re: SIMOPS Management - Drilling Activities
Effective SIMOPS management isn't just about a checklist; it’s about a live ecosystem of communication and risk assessment.
SIMOPS Matrix: This should be your baseline document. It’s a grid that plots Activity A against Activity B to determine if they are:
Permitted: No significant interference.
Restricted: Allowed only with specific controls (e.g., extra fire watch, specific PPE).
Prohibited: Too dangerous to perform together.
The SIMOPS Coordinator: A dedicated individual (often independent of the drilling crew) who maintains the responsibility, authorizes daily permits, and has the power to shut down operations.
Unified Command: Daily SIMOPS meetings involving all parties (drilling, construction, production, sub-contractors) to align on the next 24 hours of movement.
For drilling activities, in particular:
Drilling + Production -> Drilling a new well while nearby wells are flowing -> Leak/Ignition (Hydrocarbon release).
Drilling + Heavy Lift -> Using a crane near the derrick or pressurized lines -> Dropped objects or line rupture.
Drilling + Maintenance -> Welding/Grinding (Hot Work) near the shaker house -> Ignition of vented gases.
I am not sure which other activities would be there at your place along with drilling to be considered within SIMOPS management.

Re: SIMOPS Management - Drilling Activities
I would rather mention some of the recommended prohibited operations:
There are specific areas where the risk becomes unmanageable. You should not allow simultaneous operations during:
Critical Well Control Phases
If the drilling team is performing a well-kill operation, handling a kick, or conducting a leak-off test (LOT), all non-essential SIMOPS must cease. The focus must be 100% on the wellbore.
High-Risk Transfers
During fuel bunkering or explosive handling (e.g., perforating gun loading), stop all nearby hot work and heavy lifts. The margin for error is zero.
Heavy Lifts over "Live" Assets
Never allow a crane to swing a load over a pressurized production manifold or a wellhead that is currently flowing, unless there is a certified "drop-protection" structure in place.
Emergency Response Drills
While it seems counterintuitive, during a full-scale emergency drill, stop actual high-risk SIMOPS. You don't want a real incident to be mistaken for part of the exercise, or vice-versa.
