Definitions
- SAGD steam-assisted gravity drainage
- U.S. Patent 6,257,334 steam-Assisted Gravity Drainage Heavy Oil Recovery Process.
- SAGD uses a pair of vertically-spaced, horizontal wells less than 10 meters apart, and careful control of the spacing is important to the technique's effectiveness.
- Other examples of directed drilling near an existing well include intersection for blowout control, multiple wells drilled from an offshore platform, and closely spaced wells for geothermal energy recovery.
- the drill bit 14 is just one piece of a bottom-hole assembly that includes one or more drill collars (thick-walled steel pipe) to provide weight and rigidity to aid the drilling process.
- drill collars include logging instruments to gather measurements of various drilling parameters such as position, orientation, weight-on-bit, borehole diameter, etc.
- the tool orientation may be specified in terms of a tool face angle (rotational orientation), an inclination angle (the slope), and compass direction, each of which can be derived from measurements by magnetometers, inclinometers, and/or accelerometers, though other sensor types such as gyroscopes may alternatively be used.
- the tool includes a 3-axis fluxgate magnetometer and a 3-axis accelerometer.
- Procedure 800 begins in block 802 with an estimation of the well casing trajectory. As this estimate will be adapted, it can be based on logging measurements from the well, or it can be an arbitrary starting point (e.g., a vertical well at some distance from the borehole). Drilling commences in block 804, creating a borehole that enters into the proximity of the existing well casing. What constitutes "proximity” may vary based on the capabilities of the system, but it is expected to include a range of at least 10 meters.
- Electromagnets or magnetic shields can alternatively be employed to implement time division multiplexing, where only one of multiple magnetic field sources is active (uncovered) at a time.
- the magnetic field of the source must be expressed in the x, y, z coordinate system defined by these equations.
- the dipole moment is orthogonal to the drill pipe (assumed vertical for simplicity - for a commercial algorithm, this will need to be modified, but for a scoping analysis, no generality is lost with this assumption). It is further assumed that the moment of the dipole makes an angle ⁇ with rexpect to the x-axis.
- the component of the field along the casing is calculated by expressing x, y and z in terms of the parameter t, the distance along the casing and projecting the field along the casing.
- ⁇ r is the relative permeability of the casing.
- the primed gradient can be commuted through the integral and does not operate on Bc.
- the induced moment should go as the cube of the distance from the source. When this is induced as a net dipole moment, it will set up another dipole field that should fall off as an inverse cube. However, there are orientations when the dipole source magnet is directly facing the casing, at the same depth as the source magnet, the induced field looks more like a monopole field.
