Abstract

A system can include an outer housing, a customized housing, and centralizing elements. The outer housing can define an inner diameter. The customized housing can be positioned approximately concentrically within the outer housing. The customized housing can include slots arranged spaced-apart around an outer diameter of the customized housing. Each slot of the plurality of slots can be sized to receive one or more centralizing elements. The centralizing elements can include the one or more centralizing elements. Each centralizing element can be sized to be positioned in a corresponding slot of the slots and to contact the inner diameter of the outer housing while located in the corresponding slot.

First claim

What is claimed is:

1 . A system comprising:
an outer housing of a wellbore tool positionable in a wellbore, the outer housing defining an inner diameter; a customized centralizing housing positionable approximately concentrically within the outer housing, the customized centralizing housing comprising a plurality of slots arranged spaced-apart around an outer diameter of the customized centralizing housing, each slot of the plurality of slots sized to receive a different centralizing element of a plurality of centralizing elements; the plurality of centralizing elements, wherein each centralizing element of the plurality of centralizing elements is sized to be positioned in a corresponding slot of the plurality of slots and to contact the inner diameter of the outer housing while located in the corresponding slot; and a plurality of end caps, wherein each end cap of the plurality of end caps is located at an end of the corresponding slot of the plurality of slots to retain a corresponding centralizing element of the plurality of centralizing elements in the corresponding slot.

2 . The system of claim 1 , wherein each slot of the plurality of slots comprises one or more retaining holes, and wherein each retaining hole of the one or more retaining holes is sized to receive a retaining element for retaining a centralizing element in a corresponding slot of the plurality of slots.

3 . The system of claim 2 , further comprising a plurality of retaining elements, wherein each retaining element of the plurality of retaining elements is positionable in a corresponding retaining hole of the one or more retaining holes of a different slot of the plurality of slots to retain a corresponding centralizing element of the plurality of centralizing elements in the different slot.

4 . The system of claim 3 , wherein the plurality of retaining elements comprises one or more retaining pins, and wherein the plurality of retaining elements has the same number of retaining elements as the plurality of slots includes slots.

5 . The system of claim 1 , further comprising one or more electronics positionable within the customized centralizing housing, wherein the one or more electronics are centerable with respect to a central axis of the outer housing by the customized centralizing housing and the plurality of centralizing elements.

6 . The system of claim 1 , wherein the plurality of centralizing elements includes a first number centralizing elements that is equal to a second number of slots included in the plurality of slots, and wherein each centralizing element of the plurality of centralizing elements has a first length that is approximately equal to a second length of the outer housing.

7 . The system of claim 1 , wherein the plurality of slots includes a first slot, a second slot, and a third slot, wherein the plurality of centralizing elements includes a first centralizing element, a second centralizing element, and a third centralizing element, and wherein the first centralizing element is located in the first slot, the second centralizing element is located in the second slot, and the third centralizing element is located in the third slot.

8 . A customized centralizing housing comprising:
an outer diameter positionable concentrically within an outer housing of a wellbore tool that is positionable in a wellbore; a plurality of slots arranged spaced-apart around the outer diameter, each slot of the plurality of slots sized to receive a different centralizing element of a plurality of centralizing elements; the plurality of centralizing elements, wherein each centralizing element of the plurality of centralizing elements is sized to be positioned in a corresponding slot of the plurality of slots and to contact an inner diameter of the outer housing while located in the corresponding slot; and a plurality of end caps, wherein each end cap of the plurality of end caps is located at an end of the corresponding slot of the plurality of slots to retain a corresponding centralizing element of the plurality of centralizing elements in the corresponding slot.

9 . The customized centralizing housing of claim 8 , wherein each slot of the plurality of slots comprises one or more retaining holes, and wherein each retaining hole of the one or more retaining holes is sized to receive a retaining element for retaining a centralizing element in a corresponding slot of the plurality of slots.

10 . The customized centralizing housing of claim 9 , further comprising a plurality of retaining elements, wherein each retaining element of the plurality of retaining elements is positionable in a corresponding retaining hole of the one or more retaining holes of a different slot of the plurality of slots to retain a corresponding centralizing element of the plurality of centralizing elements in the different slot.

11 . The customized centralizing housing of claim 10 , wherein the plurality of retaining elements comprises one or more retaining pins, and wherein the plurality of retaining elements has the same number of retaining elements as the plurality of slots includes slots.

12 . The customized centralizing housing of claim 8 , further comprising one or more electronics positionable within the customized centralizing housing, wherein the one or more electronics are centerable with respect to a central axis of the outer housing by the customized centralizing housing.

13 . The customized centralizing housing of claim 8 , wherein the plurality of centralizing elements includes a first number centralizing elements that is equal to a second number of slots included in the plurality of slots, and wherein each centralizing element of the plurality of centralizing elements has a first length that is approximately equal to a second length of the outer housing.

14 . The customized centralizing housing of claim 8 , wherein the plurality of slots includes a first slot, a second slot, and a third slot, wherein the plurality of centralizing elements includes a first centralizing element, a second centralizing element, and a third centralizing element, and wherein the first centralizing element is located in the first slot, the second centralizing element is located in the second slot, and the third centralizing element is located in the third slot.

15 . A system comprising:
an outer housing of a wellbore tool positionable in a wellbore, the outer housing defining an inner diameter; and a customized centralizing housing positionable approximately concentrically within the outer housing, the customized centralizing housing comprising:
a plurality of slots arranged spaced-apart around an outer diameter of the customized centralizing housing, each slot of the plurality of slots sized to receive a different centralizing element of a plurality of centralizing elements;
the plurality of centralizing elements, wherein each centralizing element of the plurality of centralizing elements is sized to be positioned in a corresponding slot of the plurality of slots and to contact the inner diameter of the outer housing while located in the corresponding slot; and
a plurality of end caps, wherein each end cap of the plurality of end caps is located at an end of the corresponding slot of the plurality of slots to retain a corresponding centralizing element of the plurality of centralizing elements in the corresponding slot.

16 . The system of claim 15 , wherein each slot of the plurality of slots comprises one or more retaining holes, and wherein each retaining hole of the one or more retaining holes is sized to receive a retaining e
