摘要： A method of maintaining a desired temperature at a location in a well can include adjusting fluid circulation parameters, thereby reducing a difference between an actual temperature at the location and the desired temperature. A well system can include at least one sensor, an output of the sensor being used for determining a temperature at a location in a well, and a hydraulics model which determines a desired change in fluid circulation through the well, in response to the temperature at the location being different from a desired temperature at the location. Another method of maintaining a desired temperature at a location in a well can include adjusting a density, solids content and/or flow rate of a fluid circulated through the well, thereby urging a temperature at the location toward the desired temperature.

摘要： Various logging-while-drilling (LWD) systems and methods provide resistivity logging coupled with deep detection of elongated anomalies at acute angles, enabling effective geosteering without disrupting drilling operations and without requiring intervention in the operations of the existing well. One LWD system embodiment employs a tool having tilted antennas as the transmitter and the receiver, where at least one of the antennas is placed in the vicinity of the bit, making it possible to detect existing wells at distances of 50-100 feet. In some cases, the detection distance is increased by enhancing the visibility of the existing well using a contrast fluid treatment on target well, either to fill the bore or to surround the well with treated cement or fluids that invade the formation. At least one inversion method separates the inversion of formation parameters from the inversion of parameters specifying distance, direction, and orientation of the existing well.

摘要： Disclosed drilling systems offer multiple methods providing access to the open borehole without first tripping the drill string. In some embodiments, a drill bit has a tool port that is blocked by a plug during normal drilling operations. When a tool is deployed through the interior of the drill string, the tool port opens, enabling the tool to enter the borehole beneath the drill string and perform logging or sampling operations. The plug may be attached to the drill bit by a hinge or pivot, or alternatively, the plug may be discarded and a replacement seated in place after the tool is retracted into the drill string. In other embodiments, the drill bit itself is detachable, allowing the bit to be parked in the hole or in a side bore. If desired, the bit can be re-attached by lowering the drill string to the bottom of the hole.

摘要： A multi-purpose downhole tool comprising packers for isolating an interval of a downhole formation traversed by a borehole to form a packed-off interval annulus. The tool further comprises a reversible pump and more than one interval access port located between the packers. The ports provide fluid communication with fluid in the packed-off interval annulus.

摘要： A disclosed fracture characterization method includes: collecting three-dimensional resistivity measurements of a volume surrounding an open borehole; analyzing the measurements to determine parameters describing fractures in the volume; and providing a report to a user based at least in part on said parameters. A fluid with a contrasting resistivity is employed to make the fractures detectable by a directional electromagnetic logging tool in the borehole. Illustrative parameters include fracture direction, height, extent, length, and thickness. The resistivity measurements can be augmented using a borehole wall image logging tool. Also disclosed are fracturing methods that include: positioning a directional electromagnetic logging tool proximate to a formation; fracturing the formation; monitoring fracture progression with said tool; and halting the fracturing when measurements by said tool indicate that a predetermined set of criteria have been satisfied.
