Title: Modelling a porous fractured geological medium
Inventor: SARDA SYLVAIN
IPC: E21B49/00
Filed: 1997-12-23
Abstract: A method providing a simplified approach to modelling a porous, heterogeneous geological medium (e.g. an oil reservoir crossed by an irregular fracture network) in the form of a transposed or equivalent medium equivalent to the original medium as regards a given physical transfer function consists in: a) forming an image of the original geological medium in at least two dimensions in the form of an array of pixels and associating a specific initial value to each pixel for this function, b) determining step by step values for the physical transfer function to be attributed to each pixel (e.g. the minimum distance separating the pixel from the nearest fracture) by reference to the function values attributed to adjacent pixels and c) determining a physical property of the transposed or equivalent medium by identifying the transfer function values known for the transposed medium with the transfer function values of the original medium determined step by step. The physical transfer function may represent variations between different parts of the geological medium, e.g. distances or transmissivities or thermal transfers (e.g. between a reservoir and a well crossing through the reservoir). Application to determining a transposed medium giving the same recovery of a fluid during a capillary imbibation process as the real medium.

Title: Riser tensioning devices
Inventor: DAVIES RICHARD
IPC: E21B19/00
Filed: 1998-01-22
Abstract: A riser tensioning device (10) utilises parallel air cans (16). A stem (12) having an inner diameter larger than the outer diameter of the riser (18) is positioned around the riser and is fastened in position at the well head (22) of the riser on an offshore structure. A yoke (13) attached to stem (12) supports a number of sleeves (14) around the stem (12). Each sleeve receives a variable buoyancy air can (16). Air can be injected into each open-bottomed can by an air line (40) and air delivery pipe (36) causing the water in the can to be displaced thus increasing the buoyancy of the riser. Lugs on the sides of the air cans fit into J-slots (26) provided on each sleeve (14) transferring the vertical loads of the cans to the sleeves and stem. Lifting eyes (46) allow each can to be installed or removed independently of the others.

Title: The use of [3(R)-[2-(piperidin-4-yl)ethyl]-2-piperidone-1]acetyl-3(R)-methyl-ß-alanine for inhibiting blood platelet aggregation
Inventor: COOK JACQUELYNN J
IPC: A61K31/4545
Filed: 1998-09-02
Abstract: The aggregation of blood platelets in a non-fasting human patient is inhibited by the administration of a dose of between 0.1 mg/kg and 5.0 mg/kg of [3(R)-[2-(piperidin-4-yl)ethyl]-2-pipendone-1]acetyl-3(R)- methyl- #-alanine or a pharmaceutical acceptable salt thereof. [3(R)-[2-(piperidin-4-yl)ethyl]-2-piperidone-1]acetyl-3- (R)-methyl-#-alanine is a fibrinogen receptor antagonist and prevents fibrinogen from binding to the membrane bound glycoprotein complex GP IIa/IIIb. It is preferably administered as an oral formulation, such as a tablet or capsule. This treatment reduces the adverse risk of cardiovascular events in a non-fasting human and is used to prevent thrombus or embolism formation. The [3(R)-[2-(piperidin-4-yl)ethyl]-2-piperidone- 1] acetyl-3(R)-methyl-#-alanine may be administered in two daily doses (of between 0.1 to 5.0 mg/kg) in order to reduce the fibrinogen receptor antagonist plasma level variability in the patient. The treatment may be used in combination with other anticoagulant agents, thrombotytic agents or platelet anti-aggregation agents. A number of examples of tablet and capsule formulations are given as are a number of examples of administration regimes.

Title: Vehicle drive force controller responsive to regional conditions
Inventor: TOUKURA NOBUSUKE
IPC: B60W30/18
Filed: 1997-11-19
Abstract: A vehicle drive force controller is responsive to a regional attribute or condition in which the vehicle is travelling, in order to modify a drive force characteristic of the vehicle accordingly. The drive force characteristic may be the throttle gain of an electronic throttle, the speed change pattern of an automatic transmission, or the air-fuel ratio. Furthermore, a sensor detects a travelling condition of the vehicle, and from this travelling condition a microprocessor determines whether the vehicle is in a traffic jam S51. The sensor may determine whether there is a vehicle ahead, or it may sense the frequency of acceleration or braking, or it may determine the vehicle location relative to local traffic jam information. Modification of the drive force characteristic based on a regional condition is then only carried out if the vehicle is not in a traffic jam S25. If the vehicle is in a traffic jam, the drive force is not modified S24, or alternatively it is modified to a predetermined characteristic which is independent of the regional condition (see figure 24).

Title: Method and apparatus for forming bulges in an engine oil pan
Inventor: OKUDA TSUTOMU
IPC: F01M11/00
Filed: 1999-09-07
Abstract: The oil pan 1 has a pair of side walls 7 and a front wall 8, at least one of the walls 7,8 having a bulge 14 to increase the oil capacity of the oil pan. Each bulge 14 is formed by outwardly deforming the side wall. The bulge 14 is thus integral with the wall 7,8 rather than being fastened to it so that the oil pan is easily and inexpensively formed by pressing. Since the oil pan has no joints, it is stronger and more durable. Apparatus for forming such an oil pan comprises a base 31 supporting a movable lower stage 33 which has a fixed die 35 over which an oil pan 1' without bulges is placed. Die 35 houses a pair of horizontally slidable tools 36 having a projecting dies 36a and cam surfaces 36b which can be urged apart by a lower cam 38. A pair of outer dies 40 can be urged inwardly by a pair of upper cams 46 on the upper stage 44. As the upper stage is lowered by a press, first the outer dies 40 move inwardly and contact the oil pan 1', then the upper and lower stages 33, 44 move together toward the base 31, forcing the tools 36 apart to form the bulges 14.
