Claims9
A system for transmitting data across a bottom hole assembly, the system comprising:
- a first drill collar configured to be attached to a first antenna assembly, wherein the first drill collar comprises a first hollow interior and a first exterior comprising one or more first slots configured to house one or more nonconducting materials;
- and
- a second drill collar configured to be attached to a second antenna assembly, wherein the second drill collar comprises a second hollow interior and a second exterior comprising one or more second slots configured to house the one or more nonconducting materials;
- wherein the one or more first and second slots configured to house the one or more nonconducting materials on the first drill collar, and the second drill collar, wherein the one or more first slots comprise one or more first replaceable metal slot inserts containing a first hollow in a center of a first slotted metal collar, and the one or more second slots comprise one or more second replaceable metal slot inserts containing a second hollow in a center of a second slotted metal collar, and
- wherein the one or more first replaceable metal slot inserts extend from an outer diameter of the first drill collar to an inner diameter of the first drill collar and the one or more second replaceable metal slot inserts extend from an outer diameter of the second drill collar to an inner diameter of the second drill collar,
- wherein the first hollow in the one or more first replaceable metal slot inserts extends from an outer surface of the one or more first replaceable slot inserts to an inner surface of the one or more first replaceable slot inserts and the second hollow in the one or more second replaceable metal slot inserts extends from an outer surface of the one or more second replaceable slot inserts to an inner surface of the one or more second replaceable slot inserts, and
- wherein the first hollow and the second hollow are configured to house the one or more nonconducting materials.
