9. A pressure control system to seal a wireline comprising:
a first section comprising: (a) a first upper bushing and a first lower bushing; (b) a first resilient member, which is between the first upper bushing and the first lower bushing, including a first channel to receive a wireline; and (c) a first piston coupled to a first port;
a second section comprising: (a) a second upper bushing and a second lower bushing; (b) a second resilient member, which is between the second upper bushing and the second lower bushing, including a second channel to receive the wireline; and (c) a second piston coupled to a second port;
a third section comprising: (a) a third upper bushing and a third lower bushing; (b) a third resilient member, which is between the third upper bushing and the third lower bushing, including a third channel to receive the wireline; and (c) a third piston coupled to a third port; and
wherein the first port is coupled is to a first void, the second port is coupled to a second void, and the third port is coupled to a third void;
at least one non-transitory computer readable medium comprising instructions to cause at least one processor to execute a method comprising: (1) determine a magnitude of a pressure in one of the first, second, or third voids;
and (2) in response to determining the magnitude of the pressure, moving at least one of: (2)(a) the first resilient member from an unsealed position to a sealed position by compressing the first resilient member with the first piston, (2)(b) the second resilient member from an unsealed position to a sealed position by compressing the second resilient member with the second piston, or (2)(c) the third resilient member from an unsealed position to a sealed position by compressing the third resilient member with the third piston;
wherein each of the first, second, and third pistons is respectively arranged to slide, independently of one another and non-simultaneously with one another, towards the first, second, and third resilient members to respectively compress the first, second, and third resilient members.
