20100017134 | GRAVEL PACK ASSESSMENT TOOL AND METHODS OF USE - A gravel pack evaluation tool comprised of a low energy radiation source and multiple directionally-collimated radiation detectors to analyze small, azimuthal segments of a gravel pack. Methods of use are also provided. Collimators and radiation shielding used in conjunction with multiple detector arrays allow an azimuthal segmented view of a gravel pack, particularly at certain defined depths into a gravel pack. Radioactive tracers may be used in conjunction with these tools to produce enhanced images of gravel packs and formations. | 01-21-2010 |
20100257927 | Electromagnetic Free Point Tool and Methods of Use - Electromagnetic free point tools are configured to determine the free point of a downhole pipe in a wellbore utilizing the amplitude or phase change in a transmitted signal for stressed and unstressed pipe. Certain examples of electromagnetic free point tools comprise a housing, one or more transmitter coils, one or more receiver coils, each coil spaced apart from one another, a power source for applying an oscillating voltage to the one or more transmitter coils which then induces a current in the receiver coil(s), and electronics for measuring the induced current in the receiver coil(s). In another embodiment, at least one of the coils is axially adjustable in position within the tool to permit the relative distance between coils to be adjusted to optimize performance of the tool in various conditions. By measuring the amplitude or phase of the induced current relative to the oscillating voltage, a log of the amplitude or phase is generated while passing the tool through a length of unstressed pipe. This process may be repeated while applying a stress to the pipe to generate a second log. By comparing the amplitude or phase of the first and second logs, the free point of the pipe may be ascertained by determining when and where the two logs diverge. This method can also be used to locate collars and measure pipe thickness. | 10-14-2010 |

20120119077 | Method and Apparatus For Interrogating A Subterranean Annulus - Monitoring scattered gamma rays is used to identify substances disposed between coaxial tubulars disposed in a subterranean wellbore. Gamma rays are strategically directed from within an inner most tubular and into the annulus, some of the gamma rays scatter from the substance between the tubulars and are detected with detectors set a designated axial distance from the gamma ray source. Gamma rays also scatter from fluid within the tubular, a ratio of the gamma rays detected that scatter from the fluid in the tubular and from the substance can be used to determine the substance. | 05-17-2012 |
20130009049 | Method For Inspecting A Subterranean Tubular - Substances on or adjacent a tubular disposed in a subterranean wellbore can be detected and/or their presence identified by monitoring gamma rays scattered from the substances. The substances include deposits on a sidewall of the tubular and liquid contained in the tubular. Examples of the deposits include asphaltenes, paraffins, scale, sand, and the like. Gamma rays are strategically directed from a tool disposed within the tubular and to adjacent a sidewall of the tubular. Some of the gamma rays scatter from the substances adjacent the tubular and are detected with detectors set a designated axial distance from the gamma ray source. | 01-10-2013 |
20130043381 | METHOD FOR DETECTING FRACTURES AND PERFORATIONS IN A SUBTERRANEAN FORMATION - Fractures at a wellbore wall and in a region surrounding a wellbore wall can be detected by monitoring gamma rays scattered from the fractures. Gamma rays are strategically directed from a tool disposed within the wellbore and to the wall and/or the region. Some of the gamma rays scatter from the fractures and are detected with detectors set a designated axial distance from the gamma ray source. In addition to identifying the presence of the fractures, the location and size of the fractures is also estimated. Based on the location and disposition of the fractures, perforations are formed in the formation to provide communication between the fractures and the wellbore. | 02-21-2013 |
20150027736 | DOWNHOLE WIRELINE TENSION MEASUREMENT - A downhole string and method of operating where tension in the downhole string is monitored real time so that the tension in the downhole string does not exceed its yield strength. Included with the string is a tension sub for monitoring the tension that includes a sensor in the housing of the tension sub. The sensor can be a strain gauge and can be placed proximate an upper end of the downhole string so that tension in a wireline attached to the string can also be monitored. The portion of the housing having the sensor is narrowed for enhancing sensitivity of monitoring. | 01-29-2015 |

20140291500 | Method for Evaluating Voids in a Subterranean Formation - Voids adjacent a wellbore wall and in a region surrounding a wellbore wall can be detected by monitoring gamma rays scattered from the fractures. Gamma rays are strategically directed from a tool disposed within the wellbore and to the wall and/or the region. Some of the gamma rays scatter from the voids and are detected with detectors set a designated axial distance from the gamma ray source. In addition to identifying the presence of the voids, the location and size of the fractures/perforations is also estimated. Time lapsed imaging of the wellbore wall can yield changes in the voids that in turn can affect permeability of the well. Examples of the voids include fractures and/or perforations. | 10-02-2014 |
