摘要： Techniques for determining a formation property by simplifying various two-geological-layer or multi-geological-layer models into a multi-electrical-layer model. A volume fraction of a layer in a multi-electrical-layer model is determined for an anisotropic region (sliding window) of the formation. The multi-electrical-layer electrical model includes a relative-lower-resistivity layer and a relative-higher-resistivity layer. A high-resolution resistivity measurement is used in the determination and resistivities for the relative-lower-resistivity layer and for the relative-higher-resistivity layer based on the volume fraction and bulk resistivity measure ments of the anisotropic region are determined. The formation property is based on the volume fraction, the resistivity of the relative-lower-resistivity layer, the resistivity of the relative-higher-resistivity layer, a total porosity of the anisotropic region, and bulk resistivity measurements of the region.

摘要： An apparatus and a method for controlling oilfield production to improve efficiency includes a remote sensing unit that is placed within a subsurface formation, an antenna structure for communicating with the remote sensing unit, a casing joint having nonconductive “windows” for allowing a internally located antenna to communicate with the remote sensing unit, and a system for obtaining subsurface formation data and for producing the formation data to a central location for subsequent analysis. The remote sensing unit is placed sufficiently far from the wellbore to reduce or eliminate effects that the wellbore might have on formation data samples taken by the remote sensing unit. The remote sensing unit is an active device with the capability of responding to control commands by determining certain subsurface formation characteristics such as pressure or temperature, and transmitting corresponding data values to a wellbore tool. The inventive system includes an antenna structure that is for delivering power and communication signals to the remote sensing unit. In one embodiment, the antenna structure is formed on an external surface of a wellbore casing. In another embodiment, the antenna structure is formed on a downhole tool such as a drilling collar or a cased hole wireline tool. For those embodiments in which the antenna structure is formed on a cased holed wireline tool, a casing joint is provided that includes nonconductive windows for allowing RF signals to be transmitted from within the casing to the remote sensing unit and from the remote sensing unit to the wireline tool. An inventive method therefore includes providing RF power through the inventive antenna system to the remote sensing unit to wake it up and to place it into an operational mode. The method further includes receiving modulated data values from the remote sensing unit through the antenna system that are then transmitted to the surface where operational decisions for the well may be made.

摘要： The present invention relates to a well-bore sensor apparatus and method. The apparatus includes a downhole tool carrying at least one sensor plug for deployment into the sidewall of a well-bore. The apparatus may also be used in conjunction with a surface control unit and a communication link for operatively coupling the sensor plug to the surface control unit. The sensor plug is capable of collecting well-bore data, such as pressure or temperature, and communicating the data uphole via a communication link, such as the downhole tool or an antenna. The downhole data may then be analyzed and control commands sent in response thereto. The sensor plug and/or the downhole tool may be made to respond to such control commands. In some embodiments, multiple surface control units for corresponding wells may be networked for decision making and control across multiple well-bores.

摘要： A system and method is disclosed for determining a physical characteristic or property associated with each of a plurality of layers of laminated formation traversed by a wellbore, wherein the laminated formation includes thin beds. The method includes providing one or more high resolution logs of a formation property for the laminated formation. From this log, the bed boundaries are detected and more particularly, the individual beds disposed between the boundaries. Then, the facies for each of the plurality of the beds detected is identified, using one or more high resolution logs of the laminated formation. Each of the identified facies is then defined. This includes importing volumetric descriptions for each of the facies and assigning one of the volumetric descriptions to each of a plurality of the beds detected, wherein each of the volumetric descriptions assigned to a bed is derived from a bed having the same facies. One or more squared logs for formation property is then generated by using the imported volumetric descriptions of the facies for plurality to generate a value of the formation property for each of the beds. This squared log is then convolved to generate a reconstructed log. The reconstructed log is compared with a low resolution log of the formation property for laminated formation. By adjusting the values of the squared log the difference between the reconstructed log and the squared log may be minimized. In this way, and by repeating the adjusting compared steps, and adjusted squared log may be suggested as an optimized squared log of the formation property. The optimized squared logs may then be the subject of a volumetric analyses to generate an output medium having the square log and the volumetric analyses thereon.
