Description

BACKGROUND Borehole drilled into subterranean formations may enable recovery of desirable fluids (e.g., hydrocarbons, hot water/steam) using any number of different techniques. When developing and drilling boreholes, it is important to be able to position the active borehole where desired proximate the surrounding geology of the subterranean formation and proximate adjacent boreholes. As drilling operations progress, the borehole position may change over time relative to adjacent boreholes. Generally, a subterranean formation may have any number of boreholes drilled into it. Thus, during any given drilling operation, the drilling operation may have to locate previously drilled boreholes and/or boreholes being drilled concurrently. Current technology requires deploying a source and/or receiver into an offset borehole to help in the identification of previously drilled wells or concurrent drilling operations. Specifically, a wireline operation is currently undertaken where a wireline source is deployed in offset boreholes and a source transmits from the wireline tool. As this incorporates two systems, wireline and logging-while-drilling (LWD), it is expensive and requires a large labor force. Document US 2008/0041626 A1 describes methods for drilling a first well and a second well. The method includes measuring direction and inclination for at least one of the bottom hole assemblies (BHAs) in the wells, generating a magnetic field in at least one of the BHAs and measuring the magnetic field at the other BHA. The method includes determining the geometrical relationship of one BHA with respect to the other BHA. The method further includes determining the position of one BHA with respect to the Earth's geology or geometry. The method further includes automatically positioning one well with respect to the other well to maintain a predetermined geometrical relationship between them. Document US 2016/160633 A1 describes a well casing detection system including a well casing and a ranging tool. The well casing includes a beacon with a resonant structure and a power supply. The ranging tool includes a magnetic field inducer, a magnetic field detector, and a power supply. This detection system is used to remotely detect well casing while it is deployed in a well, and may be used in conjunction with measurement while drilling (MWD) methods, logging while drilling (LWD) methods, coiled tubing drilling methods, steam assisted gravity drainage (SAGD), and wireline drilling methods, such that an operator may simultaneously direct the operation of a drill while operating the detection system.

DETAILED DESCRIPTION Described below are methods and systems for drilling multiple wells in close proximity without the need for specific offset wells in which a transmitter device and/or receiver device are disposed for tracking drilling operations. While methods and systems described below may be applied to any form of drilling operation for hydrocarbon extraction, geothermal operation, water extraction, and/or any form of fluid extraction from a subterranean formation. Systems and methods may eliminate the need to deploy a wireline source and incorporates bottom hole assembly (BHA) mounted source and (BHA) mounted receiver in a target well and offset "drilling" well with the target well being an actively drilled well or a cased or open hole well.

Generally, borehole 102 may include horizontal, vertical, slanted, curved, and other types of borehole geometries and orientations. Borehole 102 may be cased or uncased. In examples, borehole 102 may include a metallic member. By way of example, the metallic member may be a casing, liner, tubing, or other elongated steel tubular disposed in borehole 102.
