摘要:
A fluid separation method for performing fluid analysis of an unfiltered fluid. The fluid separation method includes providing a structure with a fluid analyzer and a power supply. Using a substrate for receiving a fluid flow stream of a multiphase mixture through a fluid sample inlet, wherein the substrate interconnects with the structure. Providing a membrane disposed across the fluid sample inlet for separating a fluid of interest from the multiphase mixture, wherein the fluid flow stream of the multiphase mixture has a shear rate that prevents a fouling of the membrane. Finally, the fluid separation method includes the substrate having fabricated channels, such that the fabricated channels are arranged substantially tangent to the fluid stream downstream of the porous membrane.

Methods for drilling a new well in a field having a plurality of existing cased wells using magnetic ranging while drilling are provided. In accordance with one embodiment, a method of drilling a new well in a field having an existing cased well includes drilling the new well using a bottom hole assembly (BHA) having a drill collar having by an insulated gap, generating a current on the BHA while drilling the new well, such that some of the current passes through a surrounding formation and travels along a casing of the existing cased well, measuring from the BHA a magnetic field caused by the current traveling along the casing of the existing cased well, and adjusting a trajectory of the BHA to avoid a collision between the new well and the existing cased well based on measurements of the magnetic field.
