Texas is the highest earning state in the oil and gas industry compared to other states. The exploration of oil and gas for energy production has been ongoing for the past two centuries and continues to this day. The oil and gas sector involves multiple production activities, such as drilling, extraction, and transportation of the hydrocarbons. Today, we have developed the latest technologies and innovations to enhance the efficiency and productivity of Texas oil and gas production. This article will cover the latest trends and techniques in research and development involved in the Texas oil and gas sector.

Enhanced Oil Recovery Techniques

With the development of technology, the Texas oil and gas companies have introduced modern day enhanced oil recovery techniques. Enhanced Oil Recovery (EOR), also called Tertiary Recovery, is the procedure of extracting oil from a well or any other oil field that has already passed through the primary and secondary stages of oil recovery. The residual crude is more viscous after these two initial steps. Heat is often needed to lower the viscosity of this oil in order to be able to extract more from the reservoir.

The EOR techniques are capable of extracting 30% to 60% additional oil from a reservoir following the primary and secondary stages. Below are some of the latest EOR techniques considered that are often used to extract more oil. The more advanced techniques of EOR are called Quaternary Recovery.

Polymer Flooding:

It is one of the relevant techniques for extracting oil from the reservoir. Polymer flooding enhances water viscosity, reducing permeability and improving oil mobility. The mixture of polymer molecules with water is injected inside the reservoir for a specific period, which results in the movement of water into the reservoir rock. This movement displaces the oil and causes more oil to be extracted from the reservoir. In addition to polymer molecules, the polymer gel can also be included to reduce the permeability of the water. This method can produce the oil by improving the volumetric sweep of the reservoir.

Injecting Carbon Dioxide (CO2):

After the primary and secondary stages of oil recovery, there is still a chance to extract oil from the oil field or well. When extracting oil, exceptionally deep holes and microscopic pores are left in reservoir rocks. Such remaining oil is taken out with the help of CO2.

The CO2 has the ability to dissolve the oil on any surface. The CO2 is injected into the pores of the rock in the reservoir. As injected CO2 runs through the pores of the rock, it dissolves into the remaining oil in the reservoir. Using CO2 EOR leads to increased oil extraction from the oil well as it reduces the viscosity and increases the oil’s mobility.

Thermal Injection or Steam Injection:

Some oil is left to be retrieved during the oil recovery process. In the thermal injection process, steam is injected into the reservoir; this steam produces a high temperature in the reservoir.

The increased temperatures affect the oil, resulting in a reduced oil viscosity, and oil can then be extracted from the well. Two more EOR techniques work on the same principle: Steam Flooding and Fire Flooding. In steam flooding, steam is injected, and in fire flooding, fire is injected into the reservoir.

Chemical Injection:

Some oil is left to be retrieved during the oil recovery process. In the thermal injection process, steam is injected into the reservoir; this steam produces a high temperature in the reservoir.

Microbial Injection:

In this method of EOR, the remaining oil is extracted with the help of microorganisms, also called microbes. This method is more costly, so it is rarely used. In this technique, the organisms are injected into the reservoir and fed on nutrients. As microorganisms get fed, they release gas and biosurfactants. The spread of gas and biosurfactants increases natural pressure levels and minimizes the interfacial tension. The reduction in interfacial tension increases the mobility of the oil from the reservoir and the production of oil.

Sustainable Drilling Practices

Oil well drilling can cause severe impacts to the habitat and the climate, highlighting the need for sustainable drilling practices. Well, Texas isn't taking that lightly! The government of Texas has introduced sustainable drilling practices specifically tailored to the Texas oil and gas industry and its environment.

These practices include sustainable drilling techniques that reduce the environmental impact and provide a reliable way to produce oil from the wells. The following are some of the most recent drilling techniques and the elements associated with sustainable drilling practices. Are you still intrigued by these drilling methods? Let's explore!

Directional Drilling:

Oil production companies use directional drilling for more effective extraction of oil. Directional drilling is also known as directional boring. It uses the non-vertical angle to drill a well instead of drilling straight down. The drilling is done at a particular angle where the maximum oil can be extracted. Using this drilling technique, several wells can be drilled from a single location. As the drilling is done at a particular angle, the surface disturbance is reduced, which simultaneously minimizes the requirement for well pads and overall surface footprints. It also helps improve terrestrial and marine habitats and the ecosystem, continuing sustainable Texas oil and gas industry operations.

Extended Reach Drilling (ERD):

The ERD method is considered a more advanced directional drilling method and entails drilling more extended horizontal wells at a high inclination angle. This technology, which differs from typical vertical drilling, seeks to recover oil from subsurface reserves situated far from the drilling site.

High-inclination drilling creates longer horizontal wells for extended distances. So, fewer drilling pads are needed. This method also reduces drilling sites, surface disturbance, and environmental effects.

Usage of Low-Emission Motors:

Diesel engines generally power many drilling rig motors, which release carbon monoxide (CO) and nitrogen oxides (NOx) into the atmosphere. It is the main cause that can be responsible for producing air pollution in the oil extraction sector. The simplest way to reduce such emissions is to minimize using or replacing diesel engines with alternative motors.

The latest motors work on significantly less electrical energy. Some motors, like synchronous motors and induction motors, can constantly work on renewable energy; therefore, they consume significantly less energy received from renewable energy sources than the fuel required in diesel engines.

Such substitutions will cut emissions and be accountable for reducing excessive noise and petroleum fuel on drilling sites. This major adjustment can reduce air emissions, remove carbon footprints, make less noise, and make cleaner and smaller drill pads.

Advanced Seismic Imaging and Data Analysis

Most oil companies in Texas are now using modern day cutting edge seismic imaging technology and data analysis to observe the state of wells drilled for oil exploration. Advanced powerful computers and processors have been used in this cutting edge technology for seismic imaging. The drilling data has been analyzed with the involvement of advanced Artificial Intelligence (AI) and Machine Learning (ML) tools. Geoscientists and engineers use these methods to determine the well's condition and depth. The latest cutting-edge seismic imaging technologies and data analysis techniques are used while drilling the oil well.

3D and 4D Seismic Imaging Technique:

A 3D seismic imaging method is used to get the data as images in a three-dimensional model. It provides a detailed representation of the surface layers of a drilled well. By observing the 3D state of the well, the geoscientists conclude the state of the well and whether further drilling is to be done or not if it is in a declining state.

Similarly, the 4D technique monitors the transformation in the reservoir during production activities. Numerous seismic surveys during the life of the field are used in 4D seismic imaging to monitor variations in the subsurface caused by hydrocarbon production. Because of economic considerations in certain geological settings, most 4D activity occurs offshore. Through numerous studies and modifications, software such as CoViz 4D and EarthVision allow interpreters to depict seismic data correctly.

Full Waveform Inversion (FWI):

Full Waveform Inversion is again the latest seismic imaging technique that involves a nonlinear data fitting process. This technique uses the whole seismic wavefield to integrate amplitude and phase information to create a high-definition model. FWI optimized in the estimation of surface properties taken from seismic data.

By carrying out this technique, the image results received are either positive or negative. This technique shows exact detailed surface images by adjusting the 3D image model until the recorded model matches the seismic data model.

Multi-Component Seismic Image Technique:

Multi-component seismic imaging is preferred for getting information on all the vertical and horizontal components associated with drilling a well. It shows the exact condition of rocks and their properties and high-resolution images of complex geological areas.

Involvement of Artificial Intelligence and Machine Learning:

In the dynamic world of oil drilling, we're seeing a real revolution thanks to AI. It's not just about gathering heaps of data from drilling sites anymore. Now, we use AI to sift through this data, finding the sweet spots that promise richer oil yields. This isn't just a time-saver; it's reshaping the economics of the entire operation. We're drilling fewer dry wells, which is great for the budget and even better for the environment.

Visualization and Integration of Data:

When it comes to making sense of all the data from drilling sensors, geophysical surveys, and historical records, the game has changed. We're not just collecting data; we're weaving it into a coherent story. Tools like Google Charts, Tableau, and Grafana are our narrators, turning raw data into clear, actionable insights. This clarity is invaluable, especially when geoscientists and drilling engineers need to make critical decisions about a reservoir.

Oil Spill Prevention and Response Technologies

And let's talk about the recent incident in Texas - the oil spill in March 2023 was a wake-up call. It reminded us that even with the best technology, human error can have serious consequences. This spill, one of the largest we've seen since the start of 2022, led to about 10,000 barrels of crude oil leaking from the EnLink Midstream pipeline in Midland.

By considering such incidents, the Texas government has introduced some of the latest oil spill prevention and response technologies to prevent environmental aspects. Below are some well-known oil spill prevention and response techniques.

Oil Spill Prevention Techniques:

Using Double Layered Tankers:

The double layered tankers can be used for the transportation of oil. These tankers are made of solid materials and designed so they can not break easily and can prevent oil spills. The oil can be stored and transported using such tankers to avoid spills.

Pipeline Monitoring:

In response, Texas didn't just sit back. The state has rolled out some of the most advanced oil spill prevention and response technologies to date. We're talking about double-layered tankers that are tough enough to prevent spills, and sophisticated pipeline monitoring systems. These systems are like the high-tech guardians of the pipelines, equipped with Distributed Temperature Optical Fiber Sensors (DTSX) that can detect even the slightest temperature change, signaling a possible leak.

Remote Sensing and Satellite Monitoring:

Remote sensing and satellite monitoring have also taken center stage. These methods are especially crucial for navigating remote areas and preventing spills during oil transport. Satellites equipped with radar systems are now our eyes in the sky, swiftly detecting any oil spills in the ocean and alerting ship operators to take immediate action.

For offshore spills, we've got mechanical systems for oil recovery that are more efficient than ever. Picture this: boom systems towed in a U-shape, collecting oil as it spills. It's not just about containment; it's about recovery and ensuring that spills cause minimal environmental damage.

Response Technologies:

Oil Recovery by Mechanical Containment:

The use of mechanical systems can aid in the collection, containment, and recovery of oil spills that occur offshore. It consists of a boom system towed in a U structure by one or two vessels. These vessels absorb the spilled oil and store it in the boom apex. When a sufficient amount of oil is collected, the skimmer system installed in it quickly recovers the collected oil.

In-Situ Burning(ISB):

ISB is a process of either burning the oil that has spilled from a tank, ship, or pipeline or burning the oil on the vessel before it gets spilled in the environment. When spilled oil is in the water, the ISB method burns it before it harms marine life. The only oil with a thickness of 2 to 3 millimeters (mm) can be burned. Appropriate use of such techniques reduces the quantity of oil in the water, ultimately preventing the oil from spreading and reaching the shore and environment.

Integration of Renewable Energy Sources in Oil Production

Oil and gas production companies are expected to meet vast energy demand in Texas as they are fast-growing energy generation industries. Combining renewable energy with the oil and gas industry takes us to a sustainable energy future. Integrating sustainability will reduce environmental consequences, boost productivity, and save money. Let's dive deeper!

Integrating Solar Power in Texas Oil and Gas Companies:

Drilling rigs use fuel engines to drill wells, which release greenhouse gasses and pollute the air. Solar powered rigs can replace such drilling rigs. The generators and equipment that work on fossil fuels can be powered using solar energy.

This major transformation improves productivity without affecting the environment. It also reduces the noise levels. Solar thermal technology, specifically Concentrated Solar Power (CSP), can generate steam for improved oil recovery procedures.

Integrating Wind Energy:

Drilling rigs, generators, and other electrically powered equipment and devices are all used in oil extraction. Wind power plants can power such devices. A small wind power station near the drilling site can supply all oil extraction electricity needs.

Contribution of Hydroelectric Power:

Micro-hydroelectric stations can be built near waterfalls or springs near the drilling site. These stations will provide electricity to the devices involved in oil production activity, reducing production costs.

Digital Transformation and Automation in Oil Fields

In the oil and gas business, digital transformation and automation are improving efficiency, cost, and safety. Key oil field digital transformation and automation include:

Integration of IoT Sensors and Digital Connectivity:

The oil extracting process involves multiple pipelines and equipment. When we install IoT sensors on devices, they will provide real-time data to the operator. It will quickly identify the oil leaks by sensing variations in the flow.

Such devices enable the operator to automatically monitor and control the drilling site automatically without frequent manual inspection and interference. Some individual IoT sensors involved in fiber optic cables help map the surface drilling sites to identify exact drilling areas and utilize the output of operational sites. By this intervention, the operator gets connected digitally with the drilling site.

Automation in Drilling and Exploration:

The oil industry mainly uses Supervisory Control and Data Acquisition (SCADA) automation systems to explore oil. SCADA systems involve various control systems, such as Distribution Control Systems (DCS) and Process Control Systems (PCS), that make the operation automatic.

SCADA collects all the data and information of remote oil and gas locations and transfers it to the operator. Therefore, it becomes convenient for the operator or supervisor to get real-time information without continuous visits to the drilling site. This automation system gives accurate and efficient output and reduces excessive drilling costs and time. Automation makes oil extraction easy and green.

Currently, many companies in Texas, such as Chevron Corporation, Shell PLC, BP PLC, and Equinor, are growing rapidly with the implementation of digital technologies.
