摘要： A method and apparatus for identifying cuttings from a wellbore is disclosed. The cuttings can be identified by measuring emissions such as alpha, beta, or gamma particles which emanate from the cuttings. A continuous wellbore profile of the alpha or beta emissions can be constructed by measuring the emissions from cuttings taken from different locations in the wellbore, and by documenting such emissions. The effects of cuttings dispersion caused by differing particle sizes can be reduced by collecting cuttings of an intermediate size for analysis. The profile of the intermediate size cuttings can be compared with a well log to identify the original elevation of the cuttings within the wellbore.

摘要： The present invention is a differential pressure fluid density instrument comprising a housing having a plurality of ports positioned at spaced-apart locations along the housing, a differential pressure transducer, and a valve adapted to selectively connect the transducer across two predetermined one of the plurality of ports. The valve may comprise a three-way solenoid actuated valve. Fluid expansion wells are each connected at one end to a port and prevent wellbore fluids from reaching the differential pressure transducer. The housing includes an inner chamber filled with liquid which may be silicon oil. The chamber includes a standpipe which extends from near the bottom of the chamber, where it is in communication with a lower port, to the top of the chamber. Communication between the chamber and wellbore through the standpipe enables the housing and components disposed within the chamber to be constructed without the need to withstand high differential pressures.

摘要： The invention is an apparatus for rotary drilling of core samples from the wall of a wellbore. The apparatus comprises a coring bit, a motor, a bit box rotatably mounted within a housing adapted to traverse the wellbore, a plunger for extracting the core sample from the bit and discharging the core sample into a storage barrel which has a sponge liner. The sponge liner in the barrel adsorbs liquid hydrocarbons which may be expelled from the porosity in the core sample by gas exsolution.
