Gustave L Hoehn Jr: Method for directionally drilling a first well to intersect a second well. Mobil Oil Corporation, Alexander J McKillop, Michael G Gilman, Charles J Speciale, July 10, 1984: US04458767 (256 worldwide citation)

A first well is directionally drilled to intersect a second well. The second well is magnetized along its well casing to produce a magnetic anomaly which is sensed by a magnetometer located in the first. The drilling of the first well is redirected in accordance with the magnitude of the sensed anom ...

Alfred R Jennings Jr: Disposal of produced formation fines during oil recovery. Mobil Oil Corporation, Alexander J McKillop, Michael G Gilman, Charles A Malone, November 29, 1988: US04787452 (242 worldwide citation)

Recovered formation fines are pumped in slurry form into an injection well during an enhanced oil recovery process e.g. a steam flood. Said injection can be done incrementally in stages in conjunction with said process. Said fines improve the sweep efficiency of the injected medium. This method is a ...
