In the KETA, consultant engineers and contractors working in different upstream and downstream oil and gas segments, petrochemical industries, as well as in dam, and power plants.
Our companies provide a wide range of services:
- Upstream oil and gas segment
Most oil and gas companies’ business structures are segmented and organized according to business segment, assets, or function.
The upstream oil and gas segment is also known as the exploration and production (E&P) sector because it encompasses activities related to searching for, recovering and producing crude oil and natural gas.
The upstream segment is all about wells: where to locate them; how deep and how far to drill them; and how to design, construct, operate and manage them to deliver the greatest possible return on investment with the lightest, safest and smallest operational footprint.
The exploration sector involves obtaining a lease and permission to drill from the owners of onshore or offshore acreage thought to contain oil or gas, and conducting necessary geological and geophysical (G&G) surveys required to explore for (and hopefully find) economic accumulations of oil or gas.
There is always uncertainty in the geological and geophysical survey results. The only way to be sure that a prospect is favorable is to drill an exploratory well. Drilling is physically creating the “borehole” in the ground that will eventually become an oil or gas well. This work is done by rig contractors and service companies in the Oilfield Services business sector.
The production sector of the upstream segment maximizes recovery of petroleum from subsurface reservoirs. Production activities include:
- Efficiently recovering the oil and gas in a producing filed using,
- Primary and secondary recovery methods,
- Tertiary, or enhanced oil recovery (EOR), also referred to as improved oil recovery (IOR),
- Plug and abandonment, which marks the end of the productive life of a well. That event can occur anywhere from a few years after the well is drilled to five or six decades later.
The Oilfield Services sector of the upstream segment consists of companies that build the infrastructure and provide the specialized equipment, services and skills needed for exploring, drilling, testing, producing, maintaining and reclaiming crude oil and natural gas wells.
Oilfield Services is a multi-billion dollar global industry. Numerous companies in this sector are among the world’s largest. Others are smaller, regional, or independent businesses that have also developed cutting-edge technologies.
The Oilfield Services industry provides the following support to Majors (IOCs), Independents (E&P companies), and National Oil Companies (NOC’s):
- Exploration services involve the use of seismic methods to evaluate where and how to prove a drilling prospect, high-speed computers and advanced, 3D, visual interpretation theaters.
- Drilling services include well design, drilling rig operation and process, and related technologies. Other services include formation evaluation, logging, and measurement while drilling (MWD).
- Well completion involves bringing the production on line with advanced downhole equipment applications, downhole monitoring and automated well control equipment.
- Production services involve application of various physical and chemical processes to increase the amount of oil or gas that can be extracted from a field, and removing contaminates to get ready for sale.
- Offshore construction contractors provide design and construction of platforms, drilling rigs and sub-surface well completion equipment.
- Midstream oil and gas segment
As its name implies, the midstream oil and gas segment encompasses facilities and processes that sit between the upstream and downstream oil and gas segments.
Activities can include processing, storage and transportation of crude oil and natural gas.
In most cases, oil and gas reserves are not located in the same geographic location as refining assets and major consumption regions. Transportation is a big part of midstream activities and can include using pipelines, trucking fleets, tanker ships, and rail cars.
- Downstream oil and gas segment
Processing, transporting and selling refined products made from crude oil is the business of the downstream segment of the oil and gas industry.
The downstream industry provides thousands of products to end-user customers around the globe.
Many products are familiar such as gasoline, diesel, jet fuel, heating oil and asphalt for roads. Others are not as familiar such as lubricants, synthetic rubber, plastics, fertilizers and pesticides.
