Deepwater Casing Protection By Fike Corporation
Casing strings consist of multiple joints of large diameter steel pipe that are screwed together, one joint at a time, as the pipe is run into the hole. Casing strings are permanently set in oil and gas wells with the annular space between the casing and the hole filled with cement, unlike tubing strings, which are retrievable. Casing enables various critical operations during drilling, completion, and production of a well. In deeper wells there are several strings used to perform the necessary tasks at different stages of drilling and completing the well.
NUFLO™ Cone Success Story By Cameron
Much like the SAGD operations in the Canadian Oil Sands, operators in Bakersfield, CA, inject wet steam into heavy oil-bearing formations to reduce viscosity and push the oil to recovery wells. Wet steam is very tough to measure because it is multiphase, which means only a percentage of the media is steam — in this case, approximately 70 percent — and the rest is water. This creates havoc with traditional differential pressure (DP) measurement devices like the orifice plate or flow nozzle because water tends to gather in front of and behind the restrictions, which can create a faulty DP.
