(Well Test) Introduction to Radial Flow

The useful application of radial flow models is obviously dependent on making a reasonable estimate (assumption) of the extent of the region around a given well over the which the flow is radially symmetric.

(Well Test) Falloff Test

A fallout test measures the pressure decline subsequent to the closure of an injection. It’s conceptually identical to a buildup test. As with injection tests, falloff test interpretation is more difficult if the injected fluid is different from the original… Read More ›

Multi Rate Test (MRT)

Well tests conducted at a series of different flow rates for the purpose of determining well deliverability, typically in gas wells where non-Darcy flow near the well results in a rate-dependent skin effect. Multiple-rate tests are sometimes required by regulatory bodies.

PPS Gauges Memory Gauge

The PPS28 is developed for critical well testing by utilizing the high accurate and stable quartz sensors. PPS28 gauge is one of the most rugged and reliable quartz tools with low power consumption. MAJOR APPLICATIONS Drill Stem Tests Production Tests… Read More ›

How Do Subsea Trees Work?

Used on offshore oil and gas fields, a subsea tree monitors and controls the production of a subsea well. Fixed to the wellhead of a completed well, subsea trees can also manage fluids or gas injected into the well

How Do Risers Work?

The function of riser is to transfer of hydrocarbon from seafloor to production / drilling facilities above the water surface. Whether serving as a production or import/export vehicles, it is the connection between the subsea field development and production /… Read More ›

How Does a Drillship Work?

Drillship were 1st developed in the 1940s by marine architects to overcome water depth challenges offshore California in the Pacific Ocean. The 1st drillship was a surplus U.S. Navy patrol craft that was equipped with cantilevered drilling equipment. Seeing some… Read More ›
