Hybrid supercapacitor/ thermal battery system for the oil field.

[Category : - OTHER]
[Viewed 1226 times]

The problem: -

• Lithium chemistry batteries currently favored for wellbore applications have well known caveats of use, including passivation, self-discharge and have well understood safety and export issues associated with their use.

• Some oil field applications, such as sliding sleeves, valve actuation and long term reservoir monitoring require a power source which can remain dormant for many years prior to activation.

The solution: -

• Patented hybrid power pack system.

• A patented hybrid of high temperature rated supercapacitors and thermal batteries to make a battery pack which can remain dormant for decades prior to activation, and can offer similar energy density to Lithium chemistry systems.

How it works: -
• Thermally activated (“thermal”) batteries are single use primary batteries that use molten salts as electrolytes.

• Molten salts remain inert for decades prior to thermal activation.

• Once activated, a thermal battery dumps a large impulse charge into a supercapacitor array which can discharge much more slowly into an electrical load as required.

• Multiple thermal batteries can be “daisy chained” and activated as required.

• System can be triggered externally using known methods.



Financial information

Market – low level analysis
We believe that in a discussion regarding bringing a new battery power methodology to the oil and gas space, it will be prudent to zero in on an application and offer a turnkey solution to a specific problem. After establishing a viable product using our heretofore discussed battery methodology, we can broaden the market place as per the high level analysis outlined above.

Memory gauges, in the context of the oil and gas industry, are versatile tools which can be deployed in several different contexts, whether they be deployed on slickline, as part of the drill string or with tubing or coiled tubing. Specifically, some of the applications are as follows:
• DST.
Well tests conducted with the drillstring still in the hole. Often referred to as DST, these tests are usually conducted with a downhole shut-in tool that allows the well to be opened and closed at the bottom of the hole with a surface-actuated valve. One or more pressure gauges are customarily mounted into the DST tool and read and interpreted after the tests are completed.
• Flowing and PBU surveys
An analysis data obtained from measurements of the bottomhole pressure in a well that is shut-in after a flow period. The profile created on a plot of pressure against time is used with mathematical reservoir models to assess the extent and characteristics of the reservoir and the near-wellbore area.
• Pressure gradient surveys
A survey to measure pressure as a function of distance in well. This can refer to radial change in pore pressure with distance from the well (which can be calculated from well-test analysis results), to change in pore pressure with depth (which can be measured by formation tests, and implies formation fluid density and/or fluid contacts) or to change in wellbore fluid pressure with depth (which can be measured with production logs, and implies wellbore fluid density).
• Long term surveys
Logging survey of any flavor with extended duration.
Pressure and temperature is the most useful and commonly undertaken survey. As such, as an entry point to the slickline logging market, pressure and temperature is the best bet.

Reservoir monitoring metrics.

The Reservoir Analysis Market is estimated to grow from $13,561 Million in 2014 to nearly $22,432 Million by 2019 at a CAGR of 10.6%. North America, Middle East and Asia-Pacific are the three large markets in 2013 by value and are expected to continue to be in the next five years.
North American market is dominated by the data acquisition & monitoring services segment which captured more than 45% of total market in 2013. It is followed by Reservoir simulation & geo-modeling and Reservoir sampling services.
The Reservoir Analysis Market is driven by the increasing demand for energy globally. Need for maximizing recovery of hydrocarbons, continuous new field developments, and flexibility to adapt to reservoir uncertainty, from emerging economies are expected to be key drivers, globally, for this market.
The leading players in global Reservoir Analysis Market include Schlumberger Limited (U.S.), Baker Hughes Inc. (U.S.), Halliburton (U.S.), Weatherford International ltd. (Ireland), SGS SA (Switzerland), CGG SA (France), Roxar software solutions AS (Norway), ALS Oil & Gas (Australia), Core Laboratories (U.S.) Expro Group (U.K.), Geokinetices (U.S.), Intertek (U.K.), Paradigm(U.S.), Tracerco (U.K.) and Trican Well Service Limited (Canada). The top four companies, Schlumberger Limited (U.S.), Halliburton (U.S.), Baker Hughes Inc. (U.S.) and Weatherford International ltd are the predominant players in the market holding more than 80% of the market in 2013. (see appendix).
The Downhole tools market is expected to grow from an estimated USD 3.53 Billion in 2014 to USD 4.49 Billion by 2020, at a CAGR of 4.9% from 2014 to 2019. The increase in exploration activities for shale and other resources, especially in the North American region, followed by South & Central America and Asia-Pacific have led to a widespread need for downhole tools. However, the current oil price decline has impacted the downhole tools market growth.

By 2018, oil price is anticipated to reach $80 a barrel, delayed and cancelled projects are likely to resume and push the market growth.. The wireless gauge market is expected to represent around 5% of this number by 2019 or around $220,000,000.
As our offering is currently unique, a significant amount of the wireless down hole tooling power needs could be captured. We would anticipate turning over $300,000 in year one, and $1,000,000 in year 2.
