WELLHEADS LIQUIDS MEASUREMENT Liquids measurement in the oil patch is suddenly getting a lot of attention. Some are dismayed at the low level of technology used to measure liquids. Today, custody transfer of 80 to 85% of onshore crude and condensate production is still documented by a hauler climbing to the top of the tank and strapping it.…

FLOW CALIBRATING ULTRASONIC GAS METERS – CONSIDERATIONS AND BENEFITS The primary method for custody transfer measurement has traditionally been orifice metering. While this method has been a good form of measurement, technology has driven the demand for a new, more effective form of fiscal measurement. Ultrasonic flowmeters have gained popularity in recent years and have become the standard for large volume custody transfer applications…

TRANSIENT LIGHTNING PROTECTION FOR ELECTRONIC MEASUREMENT DEVICES We have all heard of or seen the devastating effects of a direct lightning burst. Communication equipment destroyed. Transmitters and EFM devices vaporized into slag metal. Complete process and measurement systems down with extended recovery times. These effects are the most dramatic and the easiest to trace. However, these kinds of events are rare. The…

PROTECTION OF NATURAL GAS MEASUREMENT EQUIPMENT AGAINST MOISTURE AND CORROSION This presentation addresses problems associated with moisture and corrosion caused by high relative humidity and airborne contaminants. By controlling moisture and corrosion long-term, many problems associated with sensitive field electronics can be avoided. INTRODUCTION The natural gas industry relies very heavily on sensitive electronic equipment utilized in the production, gathering, transportation, and distribution phases. There…

PRODUCTION EQUIPMENT EFFECTS ON GAS MEASUREMENT The drill bit penetrates a rock formation thousands of feet below the surface of the earth, a steel casing is slid into the hole, and perforations are made to the casing that reach into the surrounding rock. At that point, an escape route is created for anything in the formation that can be released to…
