What Services Do Upstream Oilfield Service Companies Offer?

The upstream segment is not only crucial in the oil and gas industry but also the basis of finding and exploring hydrocarbons. Upstream companies are involved in all the phases of the oil and gas industry, and while there are operators that own the license to the production, the technical execution is solely dependent on the oilfield service companies. Oilfield service companies provide a comprehensive solution across the industry, supporting operators with integrated, turnkey and outcome-focused services.

In layman’s terms, the upstream oil and gas companies provide 360-degree solutions and specialized expertise; from the technology to the equipment and manpower to the production of oil and gas, safely and efficiently.

Geological Services and Exploration

Prior to a well being drilled, upstream operation begins. This is to understand what lies beneath the surface. Oilfield service operations support such exploration through geological / geophysical studies, seismic data acquisition and processing, reservoir modelling and interpretation, and lastly subsurface risk analysis. Basically, these services help operators improve drilling success rates and maximize recovery with low risks.

Drilling Services

The next step is drilling. This is one of the most crucial and capital-intensive steps. It’s completely upon the oilfield service companies to perform these programs safely and efficiently. Using advanced technologies and highly experienced crews, oilfield service companies ensure smooth drilling and minimize non-productive time. Key drilling services include, drilling rig and supply management, mud logging and drilling fluids, MWD / LWD services and directional – horizontal drilling.

Construction and Casing Services

Once the well has been dug, it needs to be structurally secured to ensure it has a long life. For this exact reason the upstream oilfield companies provide with casing and tubing solution, wellhead systems, centralizers and wellbore hardware and premium OCTG. By applying best-in-class engineering practices and strict quality controls, oilfield service companies support reliable construction across all geological conditions.

Completion Servies

Oilfield service companies design tailored completions based on the reservoir type. The services often comprise of the complete design and delivery, perforating services, sand control solutions, and multistage completion systems and intelligent completion systems.  The right completion services and strategy ensure a long well life and hence reduces operating costs and improve flow rates.

Testing and Evaluation

Before a full-scale production begins, a through test and evaluation needs to be conducted. This includes surface level testing, production logging and flow state analysis. These tests basically provide a data on reservoir productivity and deliverability. Hence, reducing uncertainty and improving the economic forecasting.

Well Intervention and Workover Servies

As we know, overtime there is certain wear-and-tear, and the well is no exception. Hence, the well also requires repairs, maintenance, and/or upgrades. These are called upkeep services, and these include tubing operations, wireline services and cleanouts. These intervention services allow the operators to resolve any mechanical issues and therefore enhances productivity.

Artificial Lift and Production Optimization

Eventually, reservoir pressure declines and hence artificial systems are used to enhance the production rates. The oilfield companies install systems such as ESPs, gas lift and rod lift to maintain and enhance the production. Production optimization services analysis flow behaviour and performance of the equipment and hence these services support sustained output, improved recovery rates, and cost effective filed operations across the life of the well.

Integrated and Turnkey Services

Operating in the upstream oil and gas sector carries a unique set of considerations. Exploring in ultra-deep waters and working with higher temperatures and pressures requires increasing innovation and new technologies, operational efficiency, and strong risk management processes. Many oilfield service companies including GET Global offer integrated Crew Services (ICS). This means that one oilfield service company provides multiple services or a 360-degree solution. Thin of it as one umbrella company but many capabilities. A typical ICS includes drilling services, engineering and planning consulting, production, testing, maintenance and digital monetizing and optimization.

Procurement and Supply Chain Management

A robust supply chain management reduces downtime and reduces cost. Oilfield service companies manage end-to-end procurement and supply chain operations. This includes strategic sourcing, vendor management, equipment and materials for upstream projects. Risk management is a core focal point of procurement and supply chain services. Oilfield service companies such as GET Global implement strategic planning and supplier diversification as well as quality assurance process to mitigate any risks associated with the services.

On-demand Energy Services

ODES is a visionary approach, integrating diesel generators with cutting-edge solar photovoltaic systems to create a hybrid power solution. Oilfield companies deploy power, equipment and resources based on project specific requirements. Employing temporary power generation for drilling, testing and operations and short-term fuel supply and energy management. Oilfield companies use them for faster project mobilization and for its cost effectiveness. This in turn leads to operational flexibility, speed, testing and commissioning.

Integrated Maintenance Solutions

This is an essential tool for upstream oil and gas company to optimize production without compromising operational safety. Services usually include preventive and corrective maintenance, equipment inspections, predictive monitoring and asset performance optimization. Downhole tool maintenance services and tank inspection services such as inspection, cleaning and repairs are a part of these services.

Health, Safety, Environment Support

Safety systems are implemented along with environmental management as a strict measure in every oilfield service company. Robust HSE and compliance frameworks are met to international levels of quality as the job risk is considered extremely high in such fields.  A high-risk job demands high proactive measures and immediate solutions.

Technical Training and Consulting

Certification such as well control certification, production optimization training, HSE training, technical advisory, and risk management are some of the trainings given by oilfield service companies. This is done to maintain excellence in the workforce and ensure the workforce is up to date with time and technology. And along with this comes technical consulting such as operational audits, process, project planning and workflow optimization.

Overall, by integrating all these services, upstream oilfield service companies enable operators to focus solely on exploration and production activities with the utmost safety and compliance. Oil and gas operators can now focus on executing projects reliably while maximizing asset performance.
