EchoSmart: Revolutionizing Liquid Level Measurement in Wells

EchoSmart is an advanced instrument that continuously measures liquid levels in wells in real time—automatically and without requiring onsite personnel.

Built on cutting-edge technology and backed by 16 years of dedicated development and operational experience with approximately 7,000 units deployed in the field, EchoSmart has been widely validated for reliability and effectiveness.

Maximizing Well and Reservoir Performance

EchoSmart's real-time, continuous monitoring can significantly increase well and reservoir revenue by optimizing production and operation strategy. The liquid level data it provides can be used to automatically adjust VFD drive parameters at the wellsite, ensuring liquid levels remained at the desired height. This optimization can double or even triple production, leading to substantially higher revenue.

Advanced Testing with Zero Onsite Cost

EchoSmart enables the design and execution of both steady-state and transient tests without onsite costs or production disruptions. These tests provide invaluable insights, including:

Formation parameters
Recoverable reserves estimation
Enhanced history matching for reservoir modeling for more reliable production profile prediction

With this wealth of data, company executives can make smarter, more strategic, and data-driven decisions for improved operational efficiency and long-term success.

how can echosmart boost revenue

Current technique for liquid level data

EchoSmart

By maximize well's production.

Echosmart measures liquid level data in a well in a real time mode and can send this data to VFD drive in local control panel. The PLC in the control panel can adjust motor speed to change pump stroke rate to tune production. Because of the real time measurement feature of EchSmart, liquid level in a well can be maintained at desired height, thus the productivity of the well is taken full advantage of, compared to production with high liquid level, production revenue is maximized. Usually well's production can be doubled or tripled.

No man needs to be onsite. This process is automatic.

Current liquid level data is collected by sending a technician to wellsite, connect the instrument, then fire a shot. His instrument records the echo and calculate liquid level.

The cons of this method is:

Liquid level data cannot be taken at any time, any location, or any weather
Data is isolated and cannot be used, in a real time manner
Data is not continuous, at most it is sporadic. There cannot be a close loop to help VFD drive to maintain liquid level to certain height
Cost. Each trip to the wellsite costs a few hundred dollars, for a few liquid level points

By boosting revenue of the whole oilfield

In addition to maximizing a well's production, EchoSmart can also provide crucial data for strategy management of oil and gas field, by helping to achieve better history matching.

We depends on reservoir model, say Schlumberger Petrel, to predict production dynamics of oil and gas fields and make strategic decision.

EchoSmart can greatly improves the quality of history matching by providing long term liquid level data in a well and the whole fields, which is not possible with manned liquid level shots.

In addition to improving history matching quality, EchoSmart can also be used for steady-state well test and transient well test, to extract reservoir parameters, including, most importantly, recoverable reserves which is not available by any other means. Company executives care most of recoverable reserves.

Note: mature industry software may be needed for well test analysis including downhole pressure calculation with liquid level data.

uniqueness of echosmart

This pictures show a remote oil well, meaning EchoSmart can take liquid level measurement at any location

ANYWHERE

EchoSmart comes with WIFI and wireless data transmission capability. Liquid level data can be transmitted either through local wireless network, cellphone wireless network, or serve as a liquid level sensor for SCADA system. Virtually there is no limitation on a well's physical location to collect liquid level data.

ANY WELL

EchoSmart can work on any type of wells: oil wells (with or without casing pressure), gas wells (high pressure & low pressure), coalbed methane (CBM) wells, SAGD wells for liquid level detection, gas storage liquid level monitoring, geothermal well liquid level watching, etc... It can work wherever liquid level is needed

ANY TIME

With EchoSmart, liquid level data can be taken at any time without the presence of human being onsite. This adds great flexibility to reservoir management without cost.

ANY WEATHER

EchoSmart is engineered to perform reliably even in extreme weather conditions. Extensive field testing has demonstrated its durability and effectiveness in various environments. For more details, please refer to the next item.

EXTREMELY ROBUST

EchoSmart is designed as a comprehensive system, with every aspect carefully considered to ensure robustness. With over 16 years of field experience and iterative improvements, it is built to withstand the most challenging real-world conditions. Rigorous testing during manufacturing further enhances its durability and reliability.

To facilitate liquid level measurement, EchoSmart is designed to work independently. It runs on its own battery and a solar panel charges the battery. This makes EchoSmart self-sustained.

SELF SUSTAINED

EchoSmart operates on a battery powered by a solar panel, enabling it to function independently without external power. It is housed in an EX-rated enclosure, integrating all essential subsystems for a compact and reliable solution.

EchoSmart does not require the involvement of a person to measure liquid level in a well. It would cost a few hundred dollars for a trip of a technician to the wellsite to take a liquid level measurement shot.

NO LABOR COST

When EchoSmart is installed on new wells, a complete liquid level history becomes available from the installation. This data can be converted into accurate bottom hole pressure using industry software. A comprehensive and systematic BHP analysis allows for better reservoir characterization and optimization.

Traditional liquid level measurement uses a person to come to wellsite to take liquid level shot. The liquid level data is intermittent, maybe one data point a month. With EchoSmart, a lot of data points can be taken, say one point per hour, to provide complete liquid level history.

COMPLETE LIQUID LEVEL HISTORY

When EchoSmart is installed on new wells, a complete liquid level history becomes available from the start. This data can be converted into accurate bottom hole pressure using industry-standard software. A comprehensive and systematic BHP analysis allows for better reservoir characterization and optimization.

DATA MINING

The comprehensive liquid level history recorded by EchoSmart enables advanced data mining, uncovering deeper insights into well and reservoir behavior. This expanded understanding goes beyond traditional methods, opening new possibilities for optimizing field operations and improving overall economics.
