Sonde centralization inside a collar

A system, comprising:

• a centralizer configured to be disposed in a radial gap formed between a radially inner surface of a downhole tubular and a radially outer surface of a sonde housing, wherein the centralizer includes at least one support feature, wherein the at least one support feature comprises:
• a first circumferential end feature;
• a second circumferential end feature, wherein the first circumferential end feature includes a first end loop, wherein the second circumferential end feature includes a second end loop, and wherein the first end loop is disposed adjacent the second end loop;
• and
• an elongated body portion configured to extend axially along a centralizer axis and extend circumferentially about the centralizer axis from the first circumferential end feature to the second circumferential end feature, wherein the elongated body portion is corrugated with radially inward extending portions and radially outward extending portions alternating along the elongated body portion between the first circumferential end feature and the second circumferential end feature, and wherein the radially inward extending portions are configured to contact the sonde housing and the radially outward extending portions are configured to contact the downhole tubular to hold the sonde housing in a centralized position with respect to the downhole tubular, wherein a radially inner loop portion of the first end loop is configured to contact the radially outer surface of the sonde housing, and wherein a radially outer loop portion of the first end loop is configured to contact the radially inner surface of the downhole tubular.
