Operating on the cutting edge of technology

Exploring waters with SpiceRack

Marine seismic data acquisition, a form of surveying, is a way to explore what lies beneath the sea floor for indicators of potential oil and gas resources. Typically, this requires the use of long cables or remotely-operated vehicles to deploy sensors that can acquire seismic data. 

Our researchers knew there had to be a more efficient alternative to this costly and time-consuming method — leading them to innovate a solution that revolutionized the way our seismic surveying is done. 

By harnessing the powerful capabilities that robotics offers, Aramco collaborated with partners to create SpiceRack — an autonomous underwater vehicle (AUV) that records seismic data for subsurface imaging. 

So far, a swarm of 200 of these AUVs have explored large underwater areas for hydrocarbons. When released underwater, these AUVs autonomously reach the seabed to collect data. After the data is captured, they travel back to the surface where the data can be collected and analyzed. SpiceRack can conduct surveys in half the time it takes using conventional methods, and achieve increased efficiency with 30% lower costs. 

Capturing data with Sensor Ball

Data powers everything we do. When analyzed, it can help us identify patterns, trends, and unknown associations. For example, monitoring production and injection wells — using autonomous pressure and temperature sensors — provides critical data that is important for maintaining each well's performance.

Our scientists engineered a device that can safely and autonomously collect data inside a well and float back to the surface. When dropped inside a well, this "Sensor Ball" device sinks to reach the required depths — collecting data along the way. Once it floats back to the surface, our field technicians retrieve it and then load its stored memory onto a computer, to utilize its captured data in monitoring the health of our wells and reservoirs.

This technology enables early detection of anomalies in fluid flow and in well completion accessories — equipment used to complete the well and prepare it for production after drilling. The device is also able to detect warning signs of leaks caused by corrosion before they occur.

Enhanced water shut-off with Nanosilica 

Produced water associated with oil production is a common challenge in the field, particularly in depleted reservoirs. Due to the high-levels of salt it contains, this excess water that co-exists with hydrocarbons in reservoirs can create issues — including corrosion in pipelines, vessels, and other systems.

Our scientists saw an opportunity in utilizing nanotechnology to provide a more cost-effective and more sustainable alternative to the standard process of reducing unwanted water production. 

The fluid-based solution called "Nanosilica" turns into a gel when deployed downhole — inside the water production formation.

Made up of two components that work together, this gel acts as a sealant that blocks the porous or fractured structure of reservoir rocks — which results in hindered water production.

Simplifying cleanout with JumpStart

Our scientists came up with the idea of JumpStart to help solve a worldwide challenge that operators face in the field — when cleaning out fluids from oil and gas wells. This cleanout operation is an important step that follows the drilling process, in order to flow back — or remove — any fluids that have been used to treat the well, ensuring safety and efficiency. 

The traditional flow back and cleanout method involves the use of nitrogen gas, which is applied downhole through conventional coiled tubing, to flow back fluids from the well and prepare it for production. 

The creators of JumpStart found a unique solution to simplify the process. One that deploys an electric submersible pump (ESP) system, which runs through a slick line that is easy to install on the well, to remove heavy-weight fluids prior to oil field production. The use of the ESP system, which is fully retrievable once the operation is completed, significantly reduces flow back time by 50%, as well as the costs associated with the operation.
