Abstract
In one embodiment, the present invention includes a method of logging a rod-pumped well without removing the production string of tubing (). The logging is accomplished with a soft-coated cable () or a soft-faced sleeve () which prevents abrasion or damage to a rod-pump barrel as a logging device or sonde () which is lowered into the production string of the rod-pumped well after removal of the sucker rods and the pump assembly without the need to remove the production string. The soft-coated cable or soft-faced sleeve allows logging without damage to the interior surface of the production tubing thereby eliminating scratching or grooving normally associated with previous wireline logging operations.
