A customer wanted to test two different lithologies and compare the performance of both, in the gas window of the Neuquén Basin, in Argentina. For that reason, a slanted two-horizon target well was drilled, distributing 10 stages in the upper zone, and 10 stages in the lower zone. The intermediate zone, which was not considered a main target, received one stage.

21 unique organic gas and water tracers were added to each of the different stages of the well during stimulation. The injection was controlled and care was taken to tag all stages in the same way, ensuring that the tracers would penetrate deep into the fracture structure and make contact with formation hydrocarbons. Subsequent flowback and sample analysis for the presence of the injected tracers allowed relative gas and water flow from the different stages to be evaluated.

In any deep water field development it is important to monitor oil and water production from all wells in order to manage fluid movement and maximize hydrocarbon output. The use of Smart Tracers integrated into a lower completion, alongside the use of waterflood tracers, provides a number of advantages over traditional oil and gas inflow measurement technologies, at a fraction of the cost.

Understanding zonal contribution is imperative when developing stacked plays where a primary appraisal objective is to quantify zonal productivity to determine which layers of the formation to target. One proven evaluation method is the use of chemical-based tracer technology. In this blog post we will provide a real case example of where chemical tracer technology was used to determine zonal contribution and assist in the planning of future well and field development.

The verification of flare gas flow rates is an ongoing issue for many hydrocarbon producers globally, with strict environmental legislation continuing to impact oil or chemical processes. In this blog post we will review how the use of a Tracerco Diagnostics™ Flow Study can allow you to verify and calibrate flare flow meters, and locate the source of any fugitive flare flow, ensuring effective environmental reporting, as well as process optimisation and reduced downtime.

It is common in many oil refineries, chemical, ethanol and ammonia plants, for critical process equipment to experience problems. Issues in trayed towers such as internal tray damage, missing trays, plugged downcomers and tray foaming can all lead to off-spec production and in some cases, un-anticipated shutdowns. Scanning technology can help you avoid these scenarios by providing you with an assessment of your operating conditions, whilst your process equipment remains online. In this blog post we will feature the top three questions we are asked with regard to Trayed Towers and our Tru-Scan™ technology.

Offshore Northern Seas or ONS as it's more commonly known in Stavanger is one of my personal favourite events in the calendar. Occurring every two years, ONS is a must attend for anyone working in the oil industry in Europe and beyond. The last time I visited I could not help but be impressed by the spirit of innovation and the positive buzz around Stavanger for the duration of the show. Indeed, it is so popular that many locals leave the city for vacations and rent out their houses to visiting oil professionals in order to accommodate all the exhibitors and delegates who travel to the city for the show.

This year's event does not show any signs of being hit by the depressed oil price with 1,392 exhibitors confirmed and an additional conference arena being added this year. So why is it that the world's oil and gas industry home in on this event as a must attend in the calendar? Here are four reasons it should be on your agenda.

A Tracerco Diagnostics™ FCCU study allows refiners to identify operational and mechanical issues while the Fluid Catalytic Cracking Unit is still online. The use of Tracerco’s sophisticated scanning and tracer technologies allows refiners to improve productivity, maximise throughput, and plan any maintenance effectively. The insight provided from the study will lead to greater unit efficiency and higher profitability across the units run cycle. In this blog post we will discuss the top three questions we are asked with regard to a Tracerco Diagnostics™ FCCU study.

It's a nightmare scenario no one wants... You run a PIG and it becomes stuck in the line. You now have an unsuccessful pigging campaign, a subsea pipeline blockage, and a missing PIG to deal with.

The cost of a shutdown due to a PIG stuck in a subsea pipeline can run into tens of millions in lost production, which is why it is absolutely critical to remedy the situation as quickly as possible. In this post we will examine the first step to remedying a blocked subsea pipeline due to a stuck PIG; that is locating the stuck PIG.

Detecting and identifying small leaks in heat exchangers can be an extremely difficult and time consuming task for many operators and plant personnel. Product quality, process efficiency and the time and cost associated with maintenance and potential shutdowns caused by a leaking vessel can have a significant and detrimental impact on production and process operating margins.

In the challenging market conditions that we face today, reducing lift costs is paramount. One area where this can be achieved is through stimulation optimisation, ensuring reduce spend on stimulation activities and maximum  oil or gas flow for a particular field. 

In this post we examine five steps to achieving savings of as much as 20% in reservoir stimulation costs by using accurate flow data to optimise stage stimulation in individual wells and development of unconventional fields.

This is based on our vast experience across numerous fields and the insights and figures are taken from real projects conducted over the last few years.
