摘要： Systems and methods include a method for providing an integrated advanced visualization tool for geosteering underbalanced coiled tubing drilling (UBCTD) operations. Drilling operation data is received from different sources in real time during a drilling operation. The drilling operation data includes geological formation information recorded during the drilling operation, micropalaeontological test results of the drilling operation, drilling parameters being used during the drilling operation, cumulative productivity index calculations, and reservoir pressure information of reservoirs encountered during the drilling operation. The drilling operation data is analyzed to correlate elements of the drilling operation data by time and cumulative depth. A graph is generated in real time that includes multiple plots correlated as a function of cumulative depth over time.

摘要： Disclosed is an apparatus, method, and program product for steering a drill bit within a pay zone in a lateral well. The method includes receiving acoustic signature data from an acoustic signal analyzing apparatus. The acoustic signature data includes an amplitude spectrum and one or more acoustic characteristics evaluated from an acoustic signal provided by a sensor attached to at least one of a drive shaft and a packing box of a drill rig, and generated in real-time as a result of rotational contact of the drill bit with encountered rock in the lateral well during drilling. The method further includes comparing the received real-time acoustic signature data to predetermined acoustic signatures determined for a plurality of rock samples, and identifying a lithology type of the rock being encountered by the drill bit based on the comparison. Further, the method includes steering the drill bit in a predetermined direction, in real-time, based on the identified lithology type of the rock, for maintaining the drill bit within the pay zone of the lateral well.

摘要： Methods and systems are provided for displaying and forecasting the lithology and wellbore conditions to be encountered while conducting drill string operations are conducted in a wellbore. A method and system is described for predicting and modeling lithology while operating a drill string in a wellbore, comprising: developing a 3-D lithological model of a subsurface area; projecting a well path through said subsurface area; determining an open cylinder lithology display of said projected well path; and recording said determined open cylinder display. The open cylinder lithology display (the Predictive Stratigraphy Image) may be displayed with geological or structural cross-sections to compare the well path and the predicted well path, with the actual subsurface environment. Data acquired during drilling operations can be used in real time to update the model or the Predictive Stratigraphy Image, and the results compared with Predictive Image Logs and other wellbore images and data.

摘要： An upper end (10) for the inner tube of a core drill has a marking device comprising a pendulum (350) or hard ball (30) which runs in a circumferential track (24). The marking device adapted to be carried within a tubular upper end casing (12) which surrounds a spindle (11) which supports the inner tube of the drill. An indent washer (25) is positionable below the marking device and is oriented relative to the casing. When the upper end (10) is lifted, the marking device is driven into contact with the washer (25) and makes an impression. The orientation of the impression reveals the orientation of the drill. The impressioned washer (25) can be used to assist in noting or marking the core orientation after the drill is removed from the earth.

摘要： A wellbore trajectory survey, having an ordered plurality of survey points, is acquired. Each of the plurality of survey points has a measured depth, an inclination, and a geographic location of the point in the wellbore corresponding to the survey point. The wellbore trajectory survey is ordered on measured depth. The processor identifies a minimum lateral measured depth (min_LMD), a maximum lateral measured depth (max_LMD). The processor identifies a mid-lateral point (mid_LMP) in the plurality of survey points whose measured depth (mid_LMD) is greater than min_LMD and less than max_LMD.
