Containerized high-pressure test bays provide a contained environment for pressure testing valves, downhole tools, and other pressure-bearing equipment. However, testing requirements vary with workpiece dimensions, operating pressure, test medium, and site conditions. The enclosure layout and supporting equipment must be selected accordingly. For manufacturers and testing facilities, the right design is not necessarily the largest…

In oil and gas drilling operations, a Kelly Valve is an important valve component used to control fluid flow within the drilling system. Given the high pressures, fluid media, and complex operating conditions involved in oilfield operations, the pressure integrity, sealing performance, and operational reliability of the valve must be properly verified. For oilfield equipment…

Dissolvable bridge plugs are used in multi-stage hydraulic fracturing to isolate sections of a well during treatment. They must provide reliable sealing under the required pressure conditions and then dissolve or degrade as intended under the specified downhole environment. In order for the manufacturer or the testing engineer to prove that the functions work as…

An oilfield packer is a critical tool used in oil and gas well completion and downhole operations. Its primary function is to isolate different sections of a wellbore and control fluid flow. In complex downhole environments, pressure, temperature, mechanical loads, and fluid conditions can all affect a packer’s sealing performance and structural integrity. Packer failure may…

Well logging provides important information about subsurface formations during oil and gas exploration and production. Among the various measurements used for formation evaluation, natural gamma ray logging is one of the most widely applied methods. It records the natural gamma radiation emitted by formations and helps engineers identify changes in lithology, correlate formation intervals, and…

A dissolvable frac plug is an important downhole tool used in oil and gas well completion and multi-stage hydraulic fracturing operations. Unlike conventional frac plugs, it can gradually degrade or dissolve under specific downhole conditions, reducing the need for subsequent drilling, milling, and retrieval operations. However, before actual deployment, it is not enough to verify that…

When selecting a hydrostatic test pump or hydrostatic testing equipment, pressure is usually one of the first specifications to consider. However, choosing the right pressure is not as simple as matching the pump’s maximum pressure to the equipment’s normal working pressure. The required hydrostatic test pressure depends on the equipment being tested, applicable standards or specifications,…

Downhole tools typically operate in complex underground environments during oil and gas exploration and production. As well depth increases, these tools may be exposed to high temperatures and pressures for extended periods, as well as pressure fluctuations, sealing media, and other challenging operating conditions. Therefore, conducting High Temperature and High Pressure (HTHP) testing before downhole tools…

During oil and gas well production, the Downhole Safety Valve plays a critical role in maintaining wellbore safety. In the event of abnormal pressure or an emergency, the safety valve must close promptly to isolate the wellbore. Its sealing performance, opening and closing performance, and pressure response directly affect overall production safety. However, long-term exposure to high…

In high-pressure environments like oil & gas, chemical processing, and power plants, the Pressure Safety Valve (PSV) acts as the ultimate equipment “lifesaver.” When pressure inside a pipeline or reactor exceeds safe limits, the system relies entirely on the PSV to snap open and relieve the pressure instantly. But have you ever stopped to think: What…
