Abstract: A portable docking station and cord reel assembly (10), made for hand held electronic devices (12), includes a housing (20), a spool (22) rotatably mounted in the housing (20), a cradle (36) mounted on the spool (21), adapted to receive an electronic device (12) and in electrical communication with the electronic device (12), and at least one cable (26) at least partly carried by the spool (22) and in electrical communication with the cradle (36).

Abstract: The cord reel assembly (10) comprises a housing (12); a spool (14) mounted for rotation in the housing (12); an electrical component (15) carried by the spool (14); a first cable (16) having a first end connected to the electrical component (15), the first cable (16) being windable onto and off the spool (14), the first cable (16) having at least one longitudinal cavity (32); and cavity (32); and a second cable (22) having a first end connected to the electrical component (15), the second cable (22) being windable onto and and off the spool (14), the second cable (22) being releasably nested in the cavity (32) of the first cable (16) when when the two cables are co-wound together on the spool (14).

Abstract: A method for predicting the hydrocarbon/water contact level for oil and gas wells which relates porosity .phi., water saturation S.sub.w, air permeability k.sub.a, and capillary pressure P.sub.c. Such contact level may be estimated without actual capillary pressure measurements. The method relies on a worldwide correlation of permeability and porosity to a function of capillary pressure. The hydrocarbon/water contact levels are predicted through regression analysis using porosity .phi., water saturation S.sub.w, and air permeability k.sub.a from well log and core analysis information. Relationships used in this method include ##EQU1## where P.sub.c is mercury capillary pressure, F.sub.g is pore geometrical factor, S.sub.w is water saturation, P.sub.d is mercury displacement pressure, k.sub.a is air permeability, and .phi. is porosity. The constants set forth in equations (b) and (c) above may be adjusted to fit measured data from rock samples within the reservoir.

Abstract: For a formation zone of a well, a method for determining the relationship between bulk volume of oil .phi..sub.o as a function of total effective formation porosity .phi..sub.E and height h above the oil water contact from capillary pressure data of a core taken from the formation of the well is disclosed. The disclosed relationship of the form,.phi..sub.0 =C.phi..sub.E -K+g log hwhere C, K and g are constants derived from the capillary pressure data of the core and the relationship between h and the capillary pressure is affected by the relative densities of the connate water of the zone and the oil in the zone.According to an alternative embodiment of the invention, log data may be used to characterize a well according to the relationship.phi..sub.0 =C.phi..sub.E -K+g log hby using sets of data at different depths in the well with statistical regression methods, where the initial oil-water contact level may be determined from said log data.
