## Abstract

The use of an environmental sensing wireline standoff may improve operations during borehole logging procedures. An environmental sensing wireline standoff may comprise a lower body, an upper body, and a cable insert. The cable insert may further comprise a first segment and a second segment, wherein the cable insert is disposed between the lower body and the upper body, and wherein the cable insert is configurable to clamp directly onto a wireline cable. The environmental sensing wireline standoff may further comprise a sensor package. A method of assembling an environmental sensing wireline standoff may comprise securing a first segment of a cable insert into a lower body, securing a second segment of the cable insert into an upper body, attaching the sensor package to the upper body, and securing the lower body to the upper body.

## Claims

### Claim 1

An environmental sensing wireline standoff comprising:
a lower body;
an upper body;
a cable insert comprising:
a first segment and a second segment, wherein the cable insert is disposed between the lower body and the upper body, and wherein the cable insert is configurable to clamp directly onto a wireline cable; and
a sensor package.

### Claim 2 (depends on 1)

The environmental sensing wireline standoff of claim 1, wherein the upper body further comprises a first section and a second section, wherein the second section comprises the sensor package and a cowl.

### Claim 3 (depends on 2)

The environmental sensing wireline standoff of claim 2, wherein the first section comprises an internal cavity, wherein the sensor package is disposed in the internal cavity.

### Claim 4 (depends on 2)

The environmental sensing wireline standoff of claim 2, wherein the cowl comprises an opening in which the sensor package is disposed.

### Claim 5 (depends on 1)

The environmental sensing wireline standoff of claim 1, wherein the lower body and the upper body comprise an anti-rotation spigot.

### Claim 6 (depends on 5)

The environmental sensing wireline standoff of claim 5, wherein a central flange is disposed on the cable insert.

### Claim 7 (depends on 6)

The environmental sensing wireline standoff of claim 6, wherein the anti-rotation spigot is disposed in the central flange.

### Claim 8 (depends on 1)

The environmental sensing wireline standoff of claim 1, wherein the sensor package measures cable position, movement, rotation, and acceleration, borehole temperature and pressure, borehole fluid composition, motion and loss zones, conductivity, viscosity, gas content, road noise, borehole noise, or seismic signals.

### Claim 9 (depends on 1)
