摘要： Formation density is calculated from acoustic logging measurements. This technique does not require a radioactive source and in fact it may offer better precision particularly in rugose boreholes. In at least some embodiments, the technique exploits an observed relationship between a transmission coefficient

摘要： Method for modeling anisotropic elastic properties of a subsurface region comprising mixed fractured rocks and other geological bodies. P-wave and fast and slow S-wave logs are obtained, and an anisotropic rock physics model of the subsurface region is developed (21). P- and fast and slow S-wave logs at the well direction are calculated using a rock physics model capable of handling fractures and other geological factors (22). Calculated values are compared to measured values in an iterative model updating process (23). An upscaled ID model is developed by averaging elastic properties in each layer using an upscaling theory capable of handling at least orthorhombic anisotropy (24). The ID model may be used to generate synthetic seismic response for well ties or AVO modeling (25). Further, a method is disclosed for estimating anisotropy parameters from P- and fast/slow S-wave logs from one or more deviated wells.

摘要： Pre-drill pore pressure and fracture gradient predictions obtained from seismic velocity data are used in well design taking into account uncertainties in the velocity estimation and in the models that use the velocities to determine pore pressure. Using geological constraints, limits are established on hydrocarbon column height. It is also possible to predict the relative number of casings required to reach target reservoirs.

摘要： Disclosed is a new method for providing accurate real time predictions of pore pressure and fracture gradient, at the rig site by determining the wave velocity from drill cuttings by means of a portable continuous wave technology (CWT) tool that measures drill cuttings at high resonant frequency and then using the velocity obtained in combination with the novel method of the present invention to arrive at accurate predictions for pore pressure and fracture gradient. The new technique offers real time pore pressure prediction at the rig site with small error margin that is not otherwise available using seismic, VSP, or check shot velocities in exploration.

摘要： A method and device for imaging a description of a zone behind a casing of a well uses a logging tool provided with a plurality of acoustic transducers. The casing is insonified with a first acoustic wave using a first acoustic transducer for transmitting among the plurality of acoustic transducers. The first acoustic wave has a first mode that may be any mode of a set of modes defined as follows: extensional mode, thickness mode, flexural mode. A first acoustic transducer for receiving is selected among the plurality of transducers, a first echo is received at the first acoustic transducer for receiving, and a first signal is produced. A first measurement is extracted from the first signal. The method further comprises insonifying the casing with a second acoustic wave using a second transducer for transmitting, operating in a second mode that may be any mode of the set of modes but is distinct from the first mode. A second echo is received at a selected second acoustic transducer for receiving and a second signal is produced. A second measurement is extracted from the second signal. The description of the zone behind the casing of the well is evaluated from a combination of the first measurement and the second measurement.

摘要： The specification discloses a system and related method for determining characteristics of earth formations traversed by a borehole (12). An acoustic transmitter (18) mounted on a tool (10), whether that tool is a wireline tool or a logging-while-drilling tool, imparts acoustic energy into the formation, and a plurality of receivers (20A-D) spaced apart from the transmitter and from each other receive acoustic energy responsive to the transmitter firing. Portions, or all, of each received signal are used to estimate source signals using an assumed transfer function. Each of those estimated source signals are then compared in some way to determine an objective function. This process is repeated for multiple assumed transfer functions, and at multiple starting times within the received signals. By searching for minimas of a plot of the objective function, characteristics of the earth formation may be determined.

the drill hole measurement data are divided into successive depth bands having a predetermined depth window;

the spectral band of each separate depth band is compared with climate-related deposition cycles, such as the known Milankovitch cycle data, that relate to the examined area; and
the predetermined depth window of the depths bands is adjusted to realize an optimal correlation between the spectral band of at least one depth band and the respective cycle or cycles.

摘要： An apparatus (figure 2) and method (figure 5) for determining fast and slow shear wave velocities and orientations in an anisotropic earth formation that reduces the error and ambiguity in calculating these parameters and eliminates the need for dipole receivers (104, 106) and multiple dipole sources (102). The apparatus generally includes a single dipole source (200) for generating an acoustic signal within a borehole. The acoustic logging tool contains multiple levels of receivers. At each level, four receivers, (204, 206, 208, 210) which may be conventional pressure transducers, receive shear/flexural wave signals which propagate along the borehole earth formation. These receivers measure the pressure fields from the wave signals. A processing device (214), preferably a UNIXtm based computer, interpolates the measured pressure fields between any two adjacent receivers. The processing device performs cross-component decomposition on the pressure field to determine shear wave orientation and velocity. Using the shear wave orientation and velocity the processing device determines transit time anisotropy, energy anisotropy, and slowness anisotropy.
