Drilling Fluids Testing

The Automated Permeability Plugging Apparatus Model 389AP (APPA) is a high pressure, high temperature instrument designed to perform permeability plugging tests. The 5000 psig rated APPA is ideal for predicting how a drilling fluid can form a permeable filter cake to seal off depleted or under pressure intervals.

The Differential Sticking Tester was designed to determine how likely a given drilling fluid will be to produce a stuck pipe situation and how effective a given drilling fluid treatment or application of spotting fluid in any given drilling fluid would be in reducing this tendency. This measurement is called the Stuck Tendency Coefficient. It takes into account both the stickiness and the cake building capability of the drilling fluid. The Stuck Tendency Coefficient is determined by the Timed Filtrate Test.

The Series 300 API Low Pressure Low Temperature (LPLT) Filter Press consists of a mud reservoir mounted in a frame, a pressure source, a filtering medium, and a graduated cylinder for receiving and measuring filtrate. The basic unit has a cell assembly constructed of Stainless Steel and includes the required screen and gaskets.
