The upstream sector of the oil and gas industry covers early-stage activities such as exploration and production, geological and geophysical surveys, and well development. As operators work to extract crude oil and natural gas from challenging reservoirs, they rely on Haskel and BuTech high-pressure equipment to maintain safe, consistent performance in remote and hazardous environments.

Both independent operators and national oil companies look for high-pressure solutions that improve uptime and operational safety. As a trusted service company in the upstream market, Haskel provides air-driven pumps, gas boosters, and high-pressure valves designed to support integrated operators, contractors, and onshore/offshore teams throughout the entire supply chain. 

Haskel’s dependable high-pressure systems help upstream operators and integrated oil companies improve productivity, reduce downtime, and safely optimize performance across the reservoir lifecycle.

Whether supporting wellhead control, valve actuation, pressure testing, well equalization, or safety‑critical shutdown systems, reliable pressure generation is essential to protecting personnel, equipment, and production uptime.

Engineered for durability and continuous performance in harsh conditions, Haskel and BuTech technologies help operators maintain safe, efficient, and consistent operation.

Upstream Oil & Gas High‑Pressure Gas Handling Applications

Well Emergency Shutdown Systems (ESD)

Haskel  provide reliable hydraulic pressure for well Emergency Shutdown Systems, ensuring fast and secure actuation of kill and choke systems as well as downhole safety valves. Designed for harsh oil and gas environments, these systems automatically close during abnormal pressure conditions or well‑control incidents to protect personnel, assets, and the surrounding environment.

Well Equalization

Haskel air‑driven liquid pumps deliver controlled injection of diesel fuel or methanol to achieve precise and stable pressurization during the startup of new or shut‑in wells. By preventing sudden hydrocarbon release, providing accurate pressure control, and operating through a safe pneumatic system with no electrical power required, these pumps ensure reliable and secure well startup operations.

Valve Actuation

Haskel  deliver dependable hydraulic pressure for remotely actuated valves across pipelines and processing facilities, ensuring smooth operation under both normal and fault conditions.
Upstream

Flow control and isolation for Intervention Workover Control (IWOC) systems

BuTech high‑pressure valves provide reliable flow control and isolation for Intervention Workover Control (IWOC) systems used during well start‑up, commissioning, and light intervention work.

Built from corrosion‑resistant materials and rated for demanding offshore conditions, BuTech valves ensure leak‑tight performance in hydraulic control lines, chemical injection circuits, and emergency shutdown functions. Their robust design supports frequent cycling, high pressures, and dynamic loads, helping operators carry out IWOC operations safely and efficiently.

Accumulator Charging

Haskel gas boosters deliver safe, efficient, and reliable charging of nitrogen‑filled hydraulic accumulators and pulsation dampeners. Engineered for demanding high‑pressure environments, these boosters maximize gas usage, provide stable pressure hold without electrical power, and can elevate nitrogen pressures beyond 1,000 bar.

With rapid pressure delivery, fail‑safe performance, and true energy‑independent operation, Haskel gas boosters and gas compressors offer a dependable solution for achieving the higher pre‑charge pressures.

Offshore

Hydrostatic Pressure Testing & Leak Testing

Offshore pressure testing is essential for ensuring the integrity of valves, piping, and pressure vessels before commissioning and during maintenance. Haskel lightweight, portable hydrostatic test units can be used for pressure testing, intervention, inspection and maintenance activities. This includes bolt tensioning, power clamping, and power jacking, as well as methanol, glycol, and grease injection

Chemical Injection for Flow Assurance

Haskel high‑pressure air‑driven liquid pumps are used for controlled injection of methanol, glycol, and grease where precise pressurization and hazardous‑area suitability are required. Pneumatic operation supports hazardous locations and remote site operations without electrical power.

Relief Valve Testing & Setting for Onshore Pressure Systems

Relief valves must be verified and set accurately to protect pressurized equipment. Haskel air‑driven liquid pumps and pneumatic gas boosters support relief valve testing and setting, helping maintenance teams validate performance and reduce downtime.

Reliable Air Start Solutions for Emergency Power and Fire‑Safety Systems

Haskel air pressure amplifiers and gas booster packages provide dependable, non‑electrical engine starting for diesel‑driven generators, fire pumps, and other critical backup power units on hazardous onshore or offshore sites.

By efficiently recharging air receivers, these systems ensure engines can start instantly during emergencies, even in environments where electrical power cannot be trusted.

Gas Charging and Recovery Systems for Life‑Saving and Diving Applications

Haskel high‑pressure gas solutions deliver dependable gas charging performance for survival craft, life‑support systems, and diver gas recovery workflows.

In safety‑critical environments, Haskel gas booster systems efficiently charge onboard cylinders - conditioning air to breathable quality before pressurisation - to supply engine‑starting air, maintain positive internal air pressure, and provide essential breathing air for totally enclosed survival craft. In offshore diving operations, Haskel gas boosters also enable effective recovery and recompression of oxygen or helium dive‑gas mixtures from submerged bells, significantly reducing gas loss and supporting safe, continuous diving activity.

Dry Gas Seal & Barrier Gas Support

Haskel pneumatic gas boosters provide stable, clean, and reliable pressure support for dry gas seals and barrier gas systems on offshore rotating equipment. With a non‑electrical drive ideal for hazardous areas, these boosters help maintain consistent seal performance, reducing the risk of leaks and unplanned shutdowns. Their dependable operation ensures critical equipment remains protected and running safely in demanding offshore environments.
