Reducing Storage Tank Thief Hatch Emissions

Regulations on emissions for process manufacturers and producers have continued to grow ever stringent. Storage tanks in oil and gas production sites account for a sizable percentage of volatile organic compound (VOC) emissions. To address these regulations, you may have seen last week’s news, New ultra-tight thief hatch reduces storage tank emissions, conserves tank contents . I caught up with Emerson’s...

Smart Vapor Recovery for Oil & Gas Production Process Emissions

The Schlumberger Oil Field Glossary defines a stock tanks : A storage tank for oil production after the oil has been treated. As oil is held in these stock tanks, residual natural gas and other vapors can flash off and collect above the liquid level. Vapor recovery is the process to collect, compress and prepare this gas to be used or sold and send the liquid condensates back to the liquids in the tank. In...

Streamlining Oil & Gas Well Test Operations

The separation of oil, gas, produced water and sediments from producing oil & gas wells take place in production separators . Traditionally test separators were also installed to individually test the wells to determine their composition of these components. Technology advancements have opened up the opportunity to perform this multiphase measurement without the need for the test separator. In this short, 2-minute...

Improving Project Performance with Dynamic Simulations and Operator Training Systems

Dynamic process simulations can be used across the lifecycle of a capital project from early verification studies of process designs to training the operators to prepare to operate the running facility. For offshore oil & gas production facilities these simulations are even more important given the remoteness, space limitations and transportation requirements for the project and operating teams. In an Offshore...

Avoiding Missed Gas Volume Flow Measurements in Plunger Lift Wells

Measuring flow rates on producing gas wells can be difficult on plunger lift applications. The mechanical plungers are used to remove water slugs which build up and reduce production rates. When the plunger pulls up the well bore, the differential pressure (DP) flow measurement can spike beyond the range of the DP transmitter. This spike is caused by a surge in the flow of natural gas behind the plunger. This short...

Reducing Oil & Gas Lost and Unaccounted for Production

In oil & gas production, lost and unaccounted for (LUAF) production is : …the difference of the physical inputs and the physical outputs of the pipeline system… A “LOSS” occurs whenever the physical inputs are greater than outputs of the pipeline system. Flow measurement is a critical component in measuring for losses and for accurate custody transfer. In this quick 2:35 Custody Transfer video...

Improving Well Pad Lease Tank Oil Custody Transfer

Onshore oil & gas well pads have long used small lease tanks to hold the crude oil before transferring to be hauled away, typically by crude hauling trucks. Traditionally, this custody transfer process has involved operators climbing up the lease tanks, opening the thief hatch and using a measurement stick to manually gauge the level of the crude oil in the tank. This process subjects these operators to hazardous...

Optimizing Well Production with Downhole Reservoir Monitoring

The Offshore Technology Conference (OTC) is: …the largest event in the world for the oil and gas industry featuring more than 2,300 exhibitors, and attendees representing 100 countries. OTC 2017 will be held May 1-4 in Houston, Texas this year. With the excess supply conditions experience in oil & gas production, falling prices have meant a focus for producers on increasing efficiency. A recent NASDAQ article...

Looking Forward in the Oil & Gas Service Sector

At CERAWeek 2017 , Emerson executive president, Mike Train joined a panel to discuss ways for energy service sector companies to effectively navigate a path forward after several difficult years. Here is the abstract of the session: The extreme focus of IOCs and NOCs on reducing costs, simplifying designs, and improving operating efficiency has forced service sector companies to rethink their own business models. Many...
