Beschreibung
Zusammenfassung:	A wireline configurable toolstring is conveyed within a wellbore extending into a subterranean formation via a tubular string to which the wireline configurable tool string is coupled in a manner permitting relative motion of the wireline configurable toolstring and the tubular string. The wireline configurable toolstring converts rotary motion imparted by rotation of the tubular string, or by fluid flow resulting from reciprocation of the tubular string, into electrical energy. The wireline configurable toolstring also comprises at least one wireline configurable instrument powered by the electrical energy.
