The Joint interest billing is what CEPSA, who is the operator, sends to ERHC and to any other working interest owners to bill them for their share of what CEPSA pays to all contractors including the drillers.

In this instance, ERHC is the only other working interest owner so they are the only one billed. On other wells there could be several. The operator pays all the bills then bills the others through a joint interest billing which is often just referred to as a JIB.
