    摘要： Earth formations are characterized by using an array of electrodes which can measure streaming potentials in the formation, and by interpreting the data obtained by the electrodes. The electrodes are placed on a wireline tool, a LWD tool, or in a fixed manner about a completed wellbore. The measured streaming potentials are generated by drilling with an overbearing pressure, slitting the mudcake in a borehole, acid injection, or any of various other manners which causes fluid movement. The data obtained is interpreted to locate fractures, measure formation permeability, estimate formation pressure, monitor drilling fluid loss, detect abnormal pressure, etc. Particularly, a streaming potential voltage transient having a double peak profile signifies the presence of a formation fracture.

    摘要： A method and system of monitoring the movement of at least one front in an inter-well region is comprised of: providing a first well representing the origination of at least one front (such as a saturation front or a salinity front); providing one or more monitoring locations, each equipped with at least one sensor; and monitoring the arrival of at least one front at one or more monitoring locations. The origination well may be any type of permanent or temporary well, but is preferably an injector well. Likewise, the monitoring location(s) may be any type of permanent or temporary well such as an observation well, a production well, an exploratory well, and an appraisal well. Information regarding front arrival times may be used to characterize or appraise the formation. Front arrivals may be monitored as a function of time to develop their respective time evolution and shape.

    摘要： A method of estimating contamination of oil based mud filtrate in a hydrocarbon sample. The method comprising the steps of obtaining a hydrocarbon sample contaminated with oil based mud filtrate, then analyzing the contaminated hydrocarbon sample using two-dimensional gas chromatography (GC×GC). The method further comprises identifying one or more unique component or tracer in the oil based mud filtrate in the contaminated hydrocarbon sample. Finally, the method comprises of summing the peak volumes of the one or more unique component or tracer, relative to the peak volumes of a clean hydrocarbon sample.
