175 452, 175 451, 166297

Abstract:

A perforating gun assembly for use in perforating multiple intervals of at least one subterranean formation intersected by a cased wellbore and in treating the multiple intervals using a diversion agent, such as ball sealers. In one embodiment, the apparatus of the present invention comprises a perforating assembly having a plurality of select-fire perforating devices interconnected by connector subs, with each of the perforating devices having multiple perforating charges. The apparatus also includes at least one decentralizer, attached to at least one of the perforating devices, which is adapted to eccentrically position the perforating assembly within the cased wellbore so as to create sufficient ball sealer clearance between the perforating assembly and the inner wall of the cased wellbore to permit passage of at least one ball sealer.

International Classification:

E21B023/04

US Classification:

166382, 166120, 166213, 166387

Abstract:

A slip assembly apparatus is adapted (i) to be deployed into a wellbore (ii) to prevent axial movement of a downhole tool assembly in the wellbore when the slip assembly apparatus is actuated and external forces are imposed on the downhole tool assembly; (iii) to allow fluid flow past the slip assembly apparatus within the wellbore when the slip assembly apparatus is actuated or non-actuated; and (iv) to allow release of the slip assembly apparatus by use of a release load that is less than the axial capacity of the deployment mechanism. Different embodiments of the invention contain features such as claddings and treatments for surface hardness and wear resistance, and grooves or flutes for enhancing fluid flow between the outer diameter of the slip assembly and the inner diameter of the well casings.

Assignee:

Motorola, Inc. - Schaumburg IL

International Classification:

G06K 900

US Classification:

380259

Abstract:

Apparatus and a method are described for providing for multiple secure functions in a host or wireless radiotelephone. Access to the functionality of the radiotelephone is provided by means of a smart card or security token features contained therein. The determination of the secure function which is accessed is determined by encrypted credential information carried in the smart card. The smart card may be used for numerous applications, but is particularly useful in conjunction with radiotelephone devices having a plurality of secure communication levels. The radiotelephone device will activate the secure levels based on the security level algorithm carried in the smart card.

US Classification:

380247

Abstract:

Apparatus and a method are described for providing a security token. The security token may be used for numerous applications, but is particularly useful in conjunction with radiotelephone devices having secure functions. In accordance with the invention the user must insert a PIN and utter sounds. The radiotelephone device will activate the secure functions only if the PIN is correct and the sounds uttered are authenticated against voice feature vectors stores it the token.

International Classification:

H04Q 738

US Classification:

379 58

Abstract:

A digital satellite communication system including a local terminal coupled to a radio wireline interface through a radio satellite network. The radio wireline interface connects the radio satellite network to a public switched telephone network and a remote communication terminal. The system includes a novel method of establishing an end-to-end communication channel between local and remote terminals wherein the local terminal establishes a direct digital channel between itself and the radio wireline interface and transmits a message describing its signaling capabilities to the radio wireline interface. The radio wireline interface then trains its modem with the modem of the remote terminal such that the signaling capabilities of the local terminal are not violated. By moving the modem training procedure to the radio wireline interface, modem training response delays caused by the radio satellite network do not affect the success of establishing the end-to-end communication channel.

International Classification:

H04B 166

US Classification:

375240

Abstract:

A system (20) transmits a digital data stream (22) using a lossy compression service (24) having a communication path (28) through which compressed signals propagate. The system includes a data conditioner (36) configured to condition the received digital data stream (22) to produce data subsets (66). A frame generator (36) expands each of the data subsets (66) to generate distinct signal sets (68). The distinct signal sets (68) are expressed in a data size greater than the data subsets (66) to compensate for lossy compression cause by the lossy compression service (24). A transmitter is in communication with the frame generator (36) and transmits digitized ones of the distinct signal sets (68) in frames of a digital bit stream (126) over the communication path (28).

US Classification:

375222

Abstract:

A secure communications system (501) including a local digital terminal (510) coupled to an interworking function (538). The interworking function (538) couples the digital radio network (121) to a PSTN (542, 546, 548) and a remote analog communication terminal (552). The system (501) includes a novel method of establishing an end-to-end communication channel between local digital (510) and remote analog (552) terminals wherein the local digital terminal establishes (510) a direct digital channel (121) between itself (510) and the interworking function (538) and transmits a message describing its signaling capabilities to the interworking function (538). The interworking function (538) then trains its modem with the modem of the remote analog terminal (552) such that signaling capabilities of the local digital terminal (510) and the remote analog terminal (552) are not violated. By moving modem training procedures to the interworking function (538), signal processing delays in the local digital terminal (510) do not adversely affect the success of establishing the end-to-end communication channel.

Abstract:

Chelating acid blends for stimulation of a subterranean formation, methods of utilizing the chelating acid blends, and hydrocarbon wells that include the chelating acid blends are disclosed herein. The chelating acid blends include an acid mixture and a chelating agent or set of chelating agents. The acid mixture includes hydrochloric acid and hydrofluoric acid. The methods include providing the chelating acid blends to a wellbore of a hydrocarbon well, flowing the chelating acid blends into a subterranean formation, dissolving a fraction of a formation mineralogy of the subterranean formation with the acid mixture, and chelating poly-valent metal ions with the chelating agent. The hydrocarbon wells include a wellbore that extends within a subterranean formation, a downhole tubular that extends within the wellbore, a fracture that extends into the subterranean formation, and a chelating acid blend positioned within the fracture.
