A stud finder and template system are provided. The system has a template, and a stud finder. The template aligns with a corner of a window frame and has multiple evenly spaced holes. The stud finder has a housing, a handle, and a pin. A method of determining a location for a curtain bracket with the stud finder and template system is also provided. The template is positioned against a window frame. The stud finder is positioned against a hole in the template. The stud finder handle is depressed. A stud finder for use with a template is also provided. The stud finder has a front housing portion, a rear housing portion, an actuator handle, a pin, and a pin return spring.

Method and system is described to exploration and development hydrocarbon resources. The method involves operations for exploring and developing hydrocarbons with one or more unmanned vehicles. The unmanned vehicles are used to obtain one or more samples that may be used to identify hydrocarbon systems, such as hydrocarbon seeps.

A method includes operating a downhole acquisition tool in a wellbore in a geological formation. The wellbore or the geological formation, or both, contain a reservoir fluid. The method also includes receiving a portion of the reservoir fluid into the downhole acquisition tool and performing downhole fluid analysis using the downhole acquisition tool in the wellbore to determine at least one measurement associated with the portion of the reservoir fluid. The at least one measurement includes fluid density, optical density, or both. The method also includes using a processor of the downhole acquisition tool to obtain compressibility of the reservoir fluid based at least in part on the fluid density, the optical density, or both and determining a composition of the reservoir fluid based at least in part on the compressibility.

The present disclosure describes computer-implemented method for monitoring a well operation, the method including: accessing a plurality of streams of data received from multiple sources during the well operation, wherein: the multiple sources include a well testing process, a biosteering process, a geosteering process, and a drilling process, and the well operation includes sidetracking and drilling one or more laterals from a motherbore; combining the plurality of streams of data on a single montage with a common horizontal axis to track the one or more laterals from the motherbore; and presenting the single montage on a display device to an operator running the well operation.

A tool having an energy source and a surface roughness measurement device is provided. A baseline measurement of surface roughness of a sample is made. The sample is then exposed to energy from the energy source, causing the temperature of the sample to increase. A second measurement of surface roughness of the sample is made. The change in surface roughness of the sample is determined. Formation properties such as the total organic carbon in the sample is inferred based on the determined change in surface roughness of the sample. The tool may be disposed in a wellbore and may use packers to isolate a portion of the wellbore, or it may use a hydraulic seal on an extendible member to isolate a sample portion of the wellbore wall. The energy source may be a laser that produces radiation that selectively heats a particular component of the sample constituent material.

A data acquisition program, which includes core, image log, microseismic, DAS, DTS, and pressure data, is described. This program can be used in conjunction with a variety of techniques to accurately monitor and conduct well stimulation.

A method and system for locating subsurface ore bodies. Samples of near surface soil are collected over a predetermined geographical area. The samples are analysed to discover any chemical anomalies in the dust particles as a way of identifying possible subcropping mineralization. A tine (22) and collection tube (24) engage into subsurface soil and samples are drawn up the tube into a dust collection module (12). Sub 5 micron particles are captured on an electrostatically charged tape (40). Consecutive samples are indexed on the tape e.g. with a barcode. Collected dust samples are ablated by a laser ablation cell (72) and the ablated sample analysed by a mass spectrometer for presence of ions indicating presence of a resource body, such as a body of ore, minerals or hydrocarbons.
