North Dakota Operations
Hess has 1100 wells in Production
Plan to drill 150-200 wells this yearMost of it in-fill drilling Average of a 4 wellpad facility50+ pads/year
Utilize over 300 Service Companies across operations*Does not include material suppliers
Most D&C activities are occurring with other operations on-site

Let’s take a look at the basic challenges when conducting SimOps
Factors:

Let’s take a more granular look at the same snapshot
Environment, Health, Safety & Social Responsibility
Walking routes through the site can be extremely limited with the additional
equipment, and in this case even more so with the wet conditions
Seemingly basic tasks like using the facilities could expose workers to
traffic, equipment and/or walking/working surface hazards
Maintaining escape routes for personnel carrying vehicles
requires careful coordination and monitoring
Many work sites require exclusion zones because of the focused hazards around
certain equipment. This is one of the many reasons why increased communication is so
important
Environment, Health, Safety & Social Responsibility
What kind of precautions will need to be taken if this site with
a producing well and facilities has another well drilled?
Would the situation above be considered SimOps?
Who would ensure that
energy sources are isolated and
secured?
Environment, Health, Safety & Social Responsibility
What can we do to manage these challenges?
Factors:
Personnel Equipment Traffic Congestion Confusion
Person In Charge (PIC) Program
Utilizing STOP WORK AUTHORITY!
Pre-work Safety Meetings with all personnel on site
Pre-work Planning
Conduct Refocus Meeting(s) when Scope of Work changes
Environment, Health, Safety & Social Responsibility
Eliminate Hazards
Schedule out far enough to reduce the level of SIMOPs
Batch drilling
Batch fracking
Batch flowback

Chain of Command
As simple as it sounds, the way to safely manage the extra stuff is to identify a Person In Charge (PIC) for each of the operations on site.
An overall site PIC can be selected with additional authority/responsibility.
Once a PIC is in place, additional resources and other challenges to safe operations can be effectively managed. If unsafe conditions arise, The PIC is ultimately responsible for halting operations.

Persons in Charge
Wherever possible, the PIC should be a Hess Employee; but a Contractor may be chosen where no Hess Employee is available.

How many different operations are potentially taking place during this snapshot?
Wire line Operations
Frac Operations
Water transfer and/or heating
Sand hauling/moving on site
Designated Person for operating Well Head Valves/Controls?

Site Preparation
Aside from desktop planning, once the PICs are selected, they meet to begin pre-work planning needed on site.
Here are a few basic planning opportunities…
Equipment staging Equipment spotting requirements Equipment/operation specific exclusion zones Methods for providing exclusion Additional space needed for pivoting/moving equipment Method for safely maintaining that space Any other equipment/operation specific planning needed
Environment, Health, Safety & Social Responsibility
Equipment doesn’t end up staged in an orderly fashion by accident!

Traffic and Congestion
Will there be crowded conditions due to more vehicles involved in operations, or will there be a continuous flow of trucks bringing material needed for the operation?
More planning opportunities…
Designate direction of travel on site Designate vehicle parking areas Spotters ready to guide additional vehicles Site entry control to avoid allowing excessive amount of traffic
on site Methods for enforcing and maintaining control of vehicular
speeds
Environment, Health, Safety & Social Responsibility
What kind of preparations appear to be made in regard to dealing with traffic flow at this site?
What might have been missed?

Manage the Changing Hazards
Most shifts on work involving continuous operations last 12 hours. What are the chances that every single step discussed at the Pre-work safety meeting goes as planned?
At anytime when a change of scope occurs, a STOP WORK must be called (by anyone!) and another Refocus Meeting must take place before ANY operation can continue.
Breakdown the change of scope and discuss additional steps that need to be taken
Discuss how the changes will affect the different operations Encourage feedback from each PIC as well as the company reps
that know the most detailed information about equipment involved.
