1. A packer comprising:
a cylinder of elastomer comprising:
two flat ends;
a longitudinal axis;
an opening formed along the longitudinal axis, the opening configured to accommodate a cable; and
at least one contact pressure feature running around a circumference of the cylinder, the at least one contact pressure feature comprising at least one energizing ring extending around an outer circumference of the cylinder,
wherein the cylinder is split perpendicular to the flat ends into two halves, and
wherein compressing the packer axially causes the at least one energizing ring to exert a radial contact pressure on the cylinder of elastomer.
