| 5386719 | Debris reducing test cell for three phase meters In a three phase fluid stream microwave monitor, an improved test cell having a fluid stream flowing through it with spaced, aligned first and second antenna located within the test cell to receive microwave energy, irradiate the fluid stream, and receive... | 02/07/1995 |
| 5377753 | Method and apparatus to improve the displacement of drilling fluid by cement slurries during primary and remedial cementing operations, to improve cement bond logs and to reduce or eliminate gas migration problems Cement bonding and bond logs in wells are significantly improved by imparting random or periodic, pulsating, oscillating or vibrating pressure to the fluids present during all stages of a cementing operation. The effect is to eliminate gelation of the flu... | 01/03/1995 |
| 5368110 | Downhole rotary bearing sub A rotary bearing downhole sub has an outer housing adapted to be connected to an upper drill string and to receive therein an inner mandril adapted to be connected to a lower drill string. Both the outer housing and the inner mandril are provided with rad... | 11/29/1994 |
| 5359194 | X-ray CT measurement of secondary (vugular) porosity in reservoir core material A method for determining the secondary (Vugular) porosity of a reservoir core sample uses X-ray (CT) computed tomography to quantify the porosity. This is then compared with log derived secondary porosity and used to quantify secondary porosity heterogene... | 10/25/1994 |
| 5355313 | Neural network interpretation of aeromagnetic data A method for determining depth to basement from aeromagnetic data utilizes neural networks to automate the laborious process of profile interpretation. The neural networks provide consistency, accuracy and overall quality without bias of interpretation.... | 10/11/1994 |
| 5353627 | Passive acoustic detection of flow regime in a multi-phase fluid flow A method and apparatus for detecting the flow regime of multiphase fluid flowing in a closed pipeline system utilizes an entirely passive acoustical detector means. The acoustical pattern detected by the detector means is amplified and compared to known p... | 10/11/1994 |
| 5351755 | Method and apparatus for establish the orientation of tools in a cased borehole The steel casing of a well is deliberately magnetized with a known orientation by the passage therethrough of a tool having a demagnetizing section and a magnetizing section along with a gyrocompass section and a magnetic compass section. The casing is fi... | 10/04/1994 |
| 5339901 | Method of achieve zonal isolation Pairs of isolation members are mounted externally on casing pipe to define isolation zones. The zones are places into communication by bypass means external to the casing and penetrating the isolation members. Consolidation material is flowed through the ... | 08/23/1994 |
