Sphere of Influence and what does that mean? All of us have a Sphere of Influence which in turn impacts the overall safety of our working environment. Our Sphere of Influence can be controlled by using HES tool kits and D&C Standards to help guide us in all aspects of well construction design and actual well execution. These tools include such programs as we always honor our Tenets of Operations, Job Planning & JSA IFO Pocketbooks and its application, Stop Work Authority, OEMS with respect to Leadership Accountability, Management System Process, OE Expectations, BBS Safety programs, and our 11 D&C initiatives as “Tools of Change” to our well factory process.
