    • A catalyst composition comprising a transition metal complex selected from complexes of nickel and palladium with a fluoro-organic thiol or sulfide ligand, having a single sulfur atom in a ligating position and wherein the carbon atom adjacent the carbon to which the sulfur atom is attached has at least one fluoro substituent and with the proviso that said fluoro-organic thiol or sulfide does not contain any other ligating group or atom in a ligating position which will displace fluoro as a ligand, and an organometallic-reducing agent selected from the group of borohydride and organoaluminium halides and alkoxides. The catalyst is especially useful for the oligomerization of olefins to higher molecular weight olefins having a high degree of linearity.

    • A downhole seismic source (20) capable of generating seismic forces in excess of 1000 newtons. The source produces seismic waves for seismic applications, particularly cross borehole measurements and vertical seismic profiling. Coupled with motion sensing devices, the present invention also performs as a seismic logging tool. The source is comprised of an outer housing (32), a means (60) for clamping the source securely to the wellbore, and a linear electromagnetic actuator (30) which utilizes permanent magnetic material having remanent magnetic field exceeding about .9 T such as rare permanent magnetics. The source has a diameter of about 12.5 cm to fit within a typical wellbore and the actuator has a length of about 1 meter.
