Publication number: 20040060691Abstract: A thermal conducting material with higher thermal conductivity for a given low viscosity is shown. Carbon fibers are added to the thermal grease to promote thermal conductivity. The carbon fibers are also not highly electrically conductive, reducing the danger of short circuiting due to misapplication of the thermal grease. Due to the high thermal conductivity of the carbon fibers, a lower loading percentage is needed to obtain significant gains in thermal conductivity. The low loading percentages in turn permit lower thermal grease viscosity, which allows the thermal grease to be spread very thin during application.Type: ApplicationFiled: September 26, 2003Publication date: April 1, 2004Applicant: Intel CorporationInventors: Chia-Pin Chiu, James C.

Publication number: 20040060731Abstract: A method of patterning electrically conductive polymers is: forming a surface of a conducting polymer on a substrate, applying a mask to this surface, applying irradiation to form regions of exposed conducting polymer and regions of unexposed conducting polymer, removing the mask, and gently removing by non-chemically reactive means the regions of exposed conducting polymer.Type: ApplicationFiled: July 28, 2003Publication date: April 1, 2004Inventors: Woohong Kim, Zakya Kafafi

Publication number: 20040060732Abstract: A multichip module including a frame having contacts suitable for making an electrical connection with an article, preferably a printed wiring board or similar, which is the next level of packaging, a multilayer thin film structure mounted to the frame, and semiconductor devices mounted to the thin film structure with at least one semiconductor device on each of two opposed sides of the thin film structure. The thin film structure includes arrays of pads on opposed surfaces of the thin film structure for connecting the thin film structure to the semiconductor devices and the frame. The thin film structure further includes wiring for chip to chip connectivity and for connecting to the frame.Type: ApplicationFiled: September 27, 2002Publication date: April 1, 2004Applicant: INTERNATIONAL BUSINESS MACHINES CORPORATIONInventors: Ajay Prabhakar Giri, Joseph Michael Sullivan, Christopher Lee Tessler

Publication number: 20040060733Abstract: An electronic subassembly comprises a printed circuit board and an electronic module, particularly a ceramic module, electrically connected to one another through a planar interposer. The interposer comprises an insulator sheet and electrical spring elements joining contact sites on the module with contact pads on the PCB. The invention includes modifications that improve the integrity of electrical connections between the printed circuit board and the electronic module. This is achieved by compensating for non-planarity between the surfaces of the interposer and the module, particularly resulting from a convex curvature of the module, by minimizing relative movement, such as rocking in the x-z and y-z planes. It also includes modifications to the suspension of the module within the interposer housing to reduce the effects caused by any sliding that may occur between the interposer and the module in the x-y plane.Type: ApplicationFiled: September 17, 2003Publication date: April 1, 2004Applicant: International Business Machines CorporationInventor: William Louis Brodsky

Publication number: 20040060734Abstract: This invention relates to the field of oil wells and in particular to the explosive and other devices that are used to perforate oil well casings and hydrocarbon bearing rocks in order to create channels through which oil and gas can flow into the well bore. Existing oil well perforators are either termed “big hole” perforators which are designed to produce large holes in the oil well casing only or “deep hole” perforators which are designed to perforate the casing of the well into the surrounding rocks. This invention proposes a novel “dual action” perforator capable of substantially performing the same functions as both deep hole and big hole perforators.Type: ApplicationFiled: July 9, 2003Publication date: April 1, 2004Inventor: Brian Bourne

Publication number: 20040060735Abstract: An impulse generator (76) and method for using an impulse generator (76) to initiate a detonation in a shaped charge perforating apparatus (60) is disclosed. The shaped charge perforating apparatus (60) is adapted for use in a wellbore (62) and includes a plurality of shaped charges (86). A detonation cord (98) is operably coupled to each of the shaped charges (86). An initiator (78) is operable to detonate the detonation cord (98) upon receiving a triggering impulse. A Marx generator within the impulse generator (76) provides the triggering impulse to the initiator (78).Type: ApplicationFiled: September 26, 2002Publication date: April 1, 2004Inventor: Marvin Wayne Beckman

Publication number: 20040060736Abstract: Improved method for the drilling of the initial phase of deep water oil wells with an underwater well head consisting in the positioning and cementation of the conductor pipe and anchorage casing by means of a single drilling phase. A tapered hole (with a double diameter) is drilled using a drill string consisting of a motor driven pilot bit and a reaming bit.Type: ApplicationFiled: November 17, 2003Publication date: April 1, 2004Inventors: Angelo Calderoni, Claudio Maria Molaschi

Publication number: 20040060737Abstract: A system for controlling drilling mud density at a location either at the seabed (or just above the seabed) or alternatively below the seabed of wells in offshore and land-based drilling applications is disclosed. The present invention combines a base fluid of lesser/greater density than the drilling fluid required at the drill bit to drill the well to produce a combination return mud in the riser. By combining the appropriate quantities of drilling mud with a light base fluid, a riser mud density at or near the density of seawater may be achieved to facilitate transporting the return mud to the surface. Alternatively, by injecting the appropriate quantities of heavy base fluid into a light return mud, the column of return mud may be sufficiently weighted to protect the wellhead. At the surface, the combination return mud is passed through a treatment system to cleanse the mud of drill cuttings and to separate the drilling fluid from the base fluid.Type: ApplicationFiled: July 17, 2003Publication date: April 1, 2004Inventor: Luc deBoer

Publication number: 20040060738Abstract: A new method is disclosed for evaluating the efficiency of a sweep for removing cuttings from a borehole in a subterranean formation during a drilling operation. The method evaluates sweep efficiency on a “mass in” versus “mass out” basis. The method uses downhole density readings taken with a pressure-while-drilling tool inserted in the drill string. Measurements of hydrostatic pressure are converted into equivalent circulating density measurements which in turn are used in calculating the sweep efficiency. The method affords real time estimates at the wellsite of the quantity of formation cuttings brought out of a wellbore by a sweep.Type: ApplicationFiled: September 23, 2003Publication date: April 1, 2004Inventor: Alan Terry Hemphill

Publication number: 20040060739Abstract: A method and system for building modular platform structures from which oil and gas wells are drilled and maintained is disclosed, wherein a plurality of easily transportable, multifunctional platform modules are interconnected on-site to form a unitary platform structure. The interconnected platform modules are elevated above a ground surface on one or more legs coupled to at least one of the platform modules. The elevated, interconnected platform modules support both drilling and production operations in land-based, arctic, inaccessible, near-offshore and environmentally sensitive locations.Type: ApplicationFiled: May 8, 2003Publication date: April 1, 2004Inventors: Ali G.
