Abstract: Electrical cables are attached to an outer surface of production tubing. The electrical cables are configured to be connected at a first end to a topside electrical power supply. Electrical contacts are attached to a second end of the electrical cables. The contacts are at a downhole end of the production tubing.

Abstract: A subterranean zone fluid sample tool includes an elongated tubular tool body configured to be disposed within a wellbore formed in a subterranean zone including multiple formations. The tool body includes multiple axial portions. The tool body has a length sufficient for a respective axial portion of the multiple axial portions to reside in each formation of the multiple formations. The tool includes multiple fluid sample probes configured to sample fluids in the multiple formations. The multiple fluid sample probes are radially offset from each other on a circumferential surface of the tool body. Each fluid sample probe is attached to a respective axial portion of the tool body that is configured to reside in a respective formation. The multiple fluid sample probes are configured to simultaneously sample fluids in the respective formation.

Abstract: To condition a wellbore with a reamer on a wireline, a portion of a wellbore is formed from a surface of the earth toward a subsurface hydrocarbon reservoir using a wellbore drilling assembly. After forming the portion of the wellbore, the wellbore drilling assembly is removed from the portion of the wellbore. Using a wireline, a wellbore sampling tool and a reamer are lowered into the portion of the wellbore. While maintaining the wellbore sampling tool and the wireline in a non-rotational state, the portion of the wellbore is cleaned using the reamer.
