摘要： Methods and devices are provided for investigating an earth formation use electro-kinetics and/or electro-osmosis measurements. In one example, the method includes creating a pressure difference in the earth formation proximate to a wellbore; measuring a generated electro-kinetic property of the earth formation proximate to the wellbore, the generated electro-kinetic property generated by the pressure difference; applying an electric field to the earth formation proximate to the wellbore; measuring a generated pressure change in the earth formation proximate to the wellbore, the generated pressure change generated by the electric field; and determining wettability of the earth formation proximate to the wellbore by the use of the measurement of the generated electro-kinetic property and the measurement of the generated pressure change.

摘要： A frequency-locking device including a digitally-controlled oscillator (DCO) and a comparing unit is disclosed. The DCO is used for generating an output frequency signal. The comparing unit receives a Keep Alive signal from a universal serial bus (USB) and the output frequency signal, and compares the Keep Alive signal with the output frequency signal to generate a calibration signal. Then, the DCO adjusts the frequency of the output frequency signal according to the calibration signal to meet the USB specification for data communication.

摘要： Logging-while-drilling apparatus and methodologies for measuring streaming potential in an earth formation are provided. The apparatus and methodologies can be utilized to find information relevant to the drilling operations. In particular, since the streaming potential measurement relates directly to fluid flow, the streaming potential measurements can be used to track flow of fluids in the formation. In turn, this information may be used to find information relevant to the drilling operations, such as under-balanced drilling conditions, abnormal formation pressures, open fractures, the permeability of the formation, and formation pressure.

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.
