Crude Oil Production Overview


Natural Gas Production Overview


Well Head Production Analysis

•CHALLENGE! Multiple production points supply oil to the main pipeline with crude oil flow rates and densities that vary based on what wells are producing at one given time.

•CHALLENGE! These variations, along with different contaminants in the oil (sand, entrained gas), create a challenging environment for maintaining measurement accuracy.

•CHALLENGE! The requirement for daily over/under pipeline balance accounting requires sustainable flow measurement accuracy at every connection to the pipeline in addition to the required accuracy of the main line meter.

•CHALLENGE! Maintaining pipeline gathering throughput is critical to meet demand and any need to drain the line to remove equipment from operation involves costly maintenance and oil disposal procedures.


Crude Oil Well Head Production Analysis

•SOLUTION! Coriolis mass flow meter provides a precise picture of the quantity and quality of crude delivered from the well.

•SOLUTION! Coriolis meter is not damaged by slugs of air/gas or by sand in the oil which reduces the likelihood of measurement performance degradation or having to stop pipeline flow to perform maintenance. This increases the availability of the pipeline to transport oil, reduces maintenance and eliminates the need for added meter proving.

•SOLUTION! Remote/local diagnostics, including advanced features such as meter factor validation or coating detection, can eliminate the need to empty the line for visual inspection.

•SOLUTION! Ability to accurately measure density provides a needed variable for standard volume calculation and a process variable that can monitor crude oil quality and/or interface detection.

•SOLUTION! All information is transferred digitally for real-time communication with the central station.


Gas Well Head Production Analysis

•SOLUTION! Utilize a differential pressure measurement technique. This multi-variable system will derive temperature, density, and absolute pressure measurements in addition to the gas flow rate. Thus it provides a mass flow rate and mass total.

•SOLUTION! For Wellheads with water content, System can utilize a hydrostatic gauging system placed on the separator for measurement of water collection rates.

•SOLUTION! At the Compressor Station, use the same Coriolis method.

•SOLUTION! Method allows for characterization in two phase flows involving some portion of the gas in its liquid state providing an unparalleled precision in the gas production measurement.


Pipeline Leak and Theft Detection for Gas or Crude Oil

•CHALLENGE! Pipeline operators face the potential of leaks that statistically occur once every 20 years on short lines and every year on pipelines over 1000 miles long.

•CHALLENGE! Economic loss (Property Damage and Theft)

•CHALLENGE! Safety (fires, explosions, injuries and fatalities)

•CHALLENGE! environment (uncontained hazardous materials) are serious.

• SOLUTION! Quick response and an estimate of location and size of the leak/theft will minimize the overall damages incurred.

•SOLUTION! Install the ACT-LOGOS system at the end of the pipeline, as well as, intermediate metering stations.

•SOLUTION! Because the accuracy of measurement is so precise, the central system can alert the pipeline operator and other authorities that either a leak or theft is occurring.


Tank Farm Inventory Monitoring

•CHALLENGE! Inventory of Stored Crude & Gas

•CHALLENGE! Quality of Stored Crude & Gas

•SOLUTION! Continuously monitors the inventory of the storage tanks.

•SOLUTION! Store the data received from the pipeline and well head sub-systems

•SOLUTION! Provide the authority with knowledge of the quantity of oil as well as its characteristics like % of water and solids. If the automatic sampling system is installed, the LOGOS system will present further data on the stored crude such as sulfur content.

Method #2


Method #1: Hydrostatic Tank Gauging for Oil or Liquified Gas

•The system utilizes a hydrostatic tank gauging (HTG) technique which offers direct mass measurement.

•Can be deployed on any tank geometry as well as pressurized tanks for LNG’s.

•A transmitter near the bottom of the tank measures the static head of the liquid caused by its height and density. A transmitter on the roof of the tank may be required to compensate for the products vapor pressure. Total volume is thus determined by the function of liquid weight, vapor pressure, and tank geometry.

•Density is determined by adding a second pressure transmitter at a known distance above the main transmitter. By measuring the difference in pressure coupled with the known distance between the transmitters, the density at the temperature is determined.

•Temperature used to correct the density to API standard temperature.

•Conductivity probe will provide water levels in the tank.Click for Next

Method #2: Servo Tank Gauging for Liquids

•Method is an intelligent tank gauge for high accuracy liquid level measurement.

•Gauge can determine the interfaces between three liquids, specific gravity of these liquids and tank bottom.

•System is based on the principle of displacement measurement. A small displacer is accurately positioned in the liquid medium using a servo motor. The displacer is suspended on a measuring wire that is wound onto a finely grooved drum housing within the instrument. The drive motor is actuated to balance the voltage generated by the variations of magnetic flux to equal the reference voltage defined by the operating command. When the displacer is lowered and touches the liquid, the weight of the displacer is reduced because of the buoyant force of the liquid. As the liquid level rises and falls, the position of the displacer is adjusted by the driven motor. The rotation of the wire drum is precisely evaluated to determine the level value, which is accurate to an outstanding +/- 0.7 mm.

Custody Transfer for Oil or Gas

•CHALLENGE! Whenever Petroleum changes custody from one supplier to the next, it must be accurately measured and scrupulously accounted for.

•CHALLENGE! Custodians and regulatory agencies alike have an interest in making sure that transactions are equitable.

•CHALLENGE! Meters used for custody transfer must first comply with the applicable OIML (International Organization of Legal Metrology) standards.

•CHALLENGE! Loading facilities go from stop to full flow quickly and may contain air in the line or hose.

•CHALLENGE! Knowledge of the quality of oil being loaded is necessary to suspend operation if restrictions on water content are not met.


Custody Transfer for Oil or Gas

•SOLUTION! The specified flowmeters are compliant with the following: OIML R-117 (Measuring systems for liquids other than water), OIML R-115 (Direct mass flow measuring system for quantities of liquids), and OIML R-81 (Dynamic measuring devices for cryogenic liquids).

•SOLUTION! The specified meters have no moving parts that can be damaged by high velocities of oil resulting from a fast loading operation or slugs of air.

•SOLUTION! Density can be used to detect excess water and/or air which can automatically stop the loading process.

•SOLUTION! Mass, volume, flow-weighted averages, and instantaneous flowing density are measured in a single device thus providing custody transfer flow measurement, weight of the load, and quality monitoring.


Automatic Sampling System

•Custody transfer includes an option for obtaining pipeline samples for further analysis.

•Automated system collects three samples from the pipeline in sequence. One from the bottom, one from the center, and one from the top of the pipe in order to ensure the sample is representative.

•Samples are passed through a small flow measurement device to ensure that they are of equal volume and sent to a removable vessel. The vessel is then carried to the lab for further analysis.

•Software system allows the operator to manually initiate a sample or the program will collect the sample(s) at transferred volume points.

Online Water in Oil Analysis

•Plumbed into the pipeline at the well head, tank farm manifold, or custody transfer point in order to enhance the knowledge of the product.

•Measure both free and saturated water and has internal temperature compensation.

•Sampled and returned to the pipeline stream continuously.

•Responds very quickly to a change dielectric of the oil being monitored.

•Not affected limited by the saturation point of the liquid. Click for NextEsc to End
