摘要： A dedicated liquid level detection method having a sensor positioned into the casing of a groundwater well. The detector is in the form of an elongated thin film sensor tape that extends along the fill length of the well casing which detects the level, thickness and volume of both groundwater and any light or dense non-aqueous phase liquid that may be present. This is accomplished through the use of a conductive and hydrostatic resistive circuit measuring the level of liquids in a groundwater well at one hundredths of foot resolution or greater. Once the elongated sensor is installed, liquid levels can be gauged from the surface. The data is stored using a battery operated hand held digital display temporarily connected at the top well section casing. Since a sensor probe is not lowered into the well, cross contamination between wells is eliminated.

摘要： Many reservoirs of interest include heavy oil. In such reservoirs, parti at normal temperatures, many instruments commonly used for formation evaluation may not be able to distinguish between heavy oil and bound water in the formation. Passive or active heating is used to elevate the temperature of the fluids in the formation. At elevated temperatures, distinguishing between heavy oil and bound water is easier. Of particular interest is the increase in the resolvability of the transverse relaxation time T2 of NMR spin echo measurements. Additionally, the dielectric constant and the loss tangents of water and heavy oil show different temperature and frequency dependence.

摘要： A method is disclosed for determining a characteristic of a mud mixture surrounding a drilling tool within a borehole in which a drilling tool is received. The method includes turning the tool in the borehole. Energy is applied into the borehole from an energy source disposed in the tool. Measurement signals are received at a sensor disposed in the tool from a location around the borehole. The cross-section of the borehole is separated into at least a first sector and a second sector. A first measurement signal from the first sector is substantially in response to returning energy which results from the interaction of the applied energy with the mud mixture. A second measurement signal from the second sector is substantially in response to returning energy which results from the interaction of the applied energy with the formation. An indication of an intrinsic characteristic of the mud mixture is derived from the first measurement signals associated with the first sector of the borehole.

摘要： A method for determining the characteristics of a subterranean formation penetrated by an existing or drilled well is disclosed. The method uses a mathematical model to estimate formation parameters as fluid exits the formation through a hole and into the wellbore or tool. The model may be adapted to wells having a perforation extending from the wellbore into the formation by mathematically adjusting the perforation to the hole of the mathematical model. The formation properties may be estimated by mathematically eliminating the perforation and replacing it with an enlarged hole radius to simulate the mathematical model.

摘要： The present invention provides a method for monitoring select purge water parameters and determining when the parameters have stabilized. The method includes the steps of selecting which parameters are to be monitored and selecting the time interval between which evaluation readings are performed. The time interval may be selected in set time increments from within a predetermined time range. With the passing of each interval, the results of the evaluation readings are stored in a memory device for at least one, and more preferably a plurality, of consecutive readings. If the readings do not fall within the defined stabilization ranges for the selected parameters, the oldest scan is deleted from the memory device. The comparison of the reading results is again performed with the start of the next interval, with the new reading results being compared to the two old reading results. When the selected parameter values do fall within the defined ranges for three consecutive readings, the operator is alerted that stabilization has been obtained.

摘要： This invention provides saturated and unsaturated Vadose zone remote sample acquisition and in-situ contaminant character identification. The invention is addressed to the management of the Vadose zone. Matters of interest to the agricultural community may include, in addition to other factors, the quantity of nutrients in the saturated zone and the existence of contaminants and the potential for loss of nutrients to the unsaturated zone. Matters of interest to facilities engaging in pollution, toxic or other contaminant detection will be the presence of such contaminants in both the saturated and unsaturated zones and additionally of the transit of contaminants into the unsaturated zone having potential of interaction with the water table. The unit acquires a sample of liquid transiting the vadose zone; sensors exposed to the liquid transmit data signals regarding the quantity and character is the liquid; liquid accumulated in a unit sump is periodically pumped to uncontaminated sample liquid storage for analysis and as a resource for replenishing the liquid proximal the sensors. All activities occurring within the unit are recorded or stored by storage or computer means; control means operates pumps.

摘要： A pressure and temperature core sampler comprises a tool for recovering cores specifically enabling the evaluation of methane hydrate resources. Because methane hydrate tends to decompose under conditions of pressure decrease and/or temperature increase as the samples are retrieved to the surface, a coring tool in accordance with the present invention provides a self-contained system for retrieving core samples at or near in situ pressure while cooling the core sample. The coring tool is preferably a wire line retrievable device that provides for nearly continuous coring during the drilling operation.
