20120271549 | Method of Mapping Reservoir Fluid Movement Using Gravity Sensors - The present disclosure relates to methods and apparatuses for acquiring multi-component gravity information for an earth formation. More particularly, the present disclosure relates to estimating the movement of fluid in an earth formation using at least one gravimeter configured to generate multi-component gravity information. The method may include estimating density changes in the earth formation. The method may include estimating a position of the at least one gravimeter. The apparatus may include a multi-component gravimeter configured to estimate gravity vectors for each vector component. | 10-25-2012 |
20130191030 | DETERMINING RESERVOIR CONNECTIVITY USING FLUID CONTACT GRAVITY MEASUREMENTS - An apparatus and method for estimating reservoir connectivity using gravity estimates at a fluid contact for each of two or more boreholes. The method may include identifying fluid contacts in the boreholes. The method may include additional gravity estimates at and/or between a well head and the fluid contact of each borehole. The method may include gravity estimates along a surface between well heads of the boreholes. The method may include estimating true vertical depth for the boreholes. The apparatus may include at least one gravimeter and a processor configured to estimate reservoir connectivity using estimates from the gravimeter. | 07-25-2013 |
20130206397 | APPARATUS AND METHOD FOR POSITIONING AND ORIENTING A BOREHOLE TOOL - A downhole positioning apparatus includes: a carrier configured to be disposed in a borehole in an earth formation, the carrier including at least one measurement tool and an extendable member configured to be actuated between a first position in which the extendable member is disposed at the carrier and a second position in which the member is extended from an outer surface of the carrier; and a receiving element fixedly disposed at a borehole casing, the receiving element configured to receive the elongated member when the member is in the second position and guide the carrier to a selected orientation as the carrier is moved axially through the borehole. | 08-15-2013 |
20140165720 | ESTIMATING CHANGE IN POSITION OF PRODUCTION TUBING IN A WELL - Characterizing a parameter of interest relating to a formation intersected by a borehole. Methods may include estimating the parameter using at least one gravity measurement adjusted to account for a gravity field gradient associated with a change in a frame of reference caused by removal of a reference feature from the borehole. Methods may also include taking at least one prior gravity measurement before removal of the reference feature from the borehole; taking at least one prior gravity measurement after removal of the reference feature from the borehole; estimating the change in the frame of reference based on the prior gravity measurements taken before and after removal of the reference feature; and adjusting the at least one gravity measurement using the estimated change. | 06-19-2014 |

20100032307 | DEVICE FOR TREATING A BAND-SHAPED SUBSTRATE WITH A LIQUID - A device for treating a band-shaped substrate with a liquid, including: a conveying system including a winding system guiding the band-shaped substrate in a spiral path around the winding system with at least one winding; a first pulley rotatable about a first axis of rotation guiding the at least one winding of the band-shaped substrate through a first angle of deflection around part of the circumference of the first pulley, and a second pulley guiding the at least one winding of the band-shaped substrate through a second angle of deflection around part of the circumference of the second pulley, which is rotatable about a second axis of rotation, for each winding; and a bath of the liquid. The band-shaped substrate extends through the liquid over at least part of the length of the at least one winding. The second axis of rotation of each second pulley makes an angle alpha with the first axis of rotation. | 02-11-2010 |
20140076732 | DEVICE FOR SINGLE-SIDED ELECTROLYTIC TREATMENT OF A FLAT SUBSTRATE - The present invention provides a device for single-sided electrolytic treatment of a flat substrate. The device comprises a bath for electrolytic fluid and conveying means for conveying the flat substrate in a conveying direction at the free surface of the fluid in the bath, with the flat substrate being horizontally oriented such that the underside of the flat substrate makes contact with the free surface of the fluid in the bath. The conveying means comprise two conveying elements disposed opposite each other, which extend along two respective conveying paths, which conveying paths each comprise an electrolytic part, which electrolytic parts extend on two opposite longitudinal sides of the bath. | 03-20-2014 |
20140305770 | Transport member for transporting strip-like elements to be treated in a bath - The present invention provides a transport member for transporting strip-like elements to be treated in a bath. The transport member is provided with a horizontally oriented endless carrier belt with resilient wire-like clamping members attached thereto by means of their own resilience for the purpose of clamping the strip-like elements at the position of wire ends of the clamping members. Wire ends of adjacent clamping members are provided opposite each other for clamping the strip-like elements therebetween. | 10-16-2014 |
