The fluids are mixed or sheared for times appropriate to achieve a homogenous mixture and are then set aside to "age." Drilling fluid aging is the process in which a drilling fluid sample, previously subjected to a period of shear, is allowed to more fully develop its rheological and filtration properties. Aging is done under conditions which vary from static to dynamic...

The Model RC-820 Rig Laboratory is a drilling fluid analysis kit designed to serve as a work station where wellsite personnel can carry out the usual standard drilling fluid checks. Included in the Rig Laboratory is a mud balance, marsh funnel, measuring cup, filter press, Sand Content Kit, timer, and all the reagents and labware for performing chloride ion analysis. Du...

API Low Pressure, Low Temperature (LPLT) Filter Presses are the most effective means of determining the filtration properties of drilling muds and cement slurries. Measuring filtration behavior and wall-cake building characteristics of a mud is essential to drilling fluid control and treatment. The characteristics of the filtrate, such as oil, water or emulsion conten...

The RC-130 series Digital Rheometer gives new meaning to the term stand-alone.” API Tests Pre-programmed: This rheometer is equipped with R1 Rotor Sleeve, B1 Bob, F1 Torsion Spring, and a stainless steel,sample cup for testing according to American Petroleum Institute Recommended Practice. • OLED display for easier reading • Push button design for easy operation ...

It has been widely applied in the oil fields, geological exploration and laboratories for analysis and measurements of fluid density. Compare with the model RCMB liquid-densitometer manufactured by our factory, the instrument is made wholly of metallic material and characterized by its impregnability, duration for using, fine anti-impact surfaces, stable measured data an...

The Test determines the amount of reactive solids in a fluid sample, based on the cation exchange capacity of the solids. Methylene blue solution is added to a sample of drilling fluid, which has been treated with hydrogen peroxide and acidified, until saturation is noted by the formation of a dye halo. Reference: API Recommended Practice 13B-1 Text Kit Shows the...

The Oil and Water Retort provides a simple, direct field method for determining the percent by volume of oil and water in samples in drilling mud or in core samples of the formation. The Retort has been found to be especially useful in determining the oil content of emulsion muds Suspended and dissolved solids are determined by subtracting these from 100 percent of the i...

have conventional wireline anchors, RIGCHINA offers several weight indicator solutions. These include Clipper type weight indicators that have a diaphragm that clamps to the deadline and Summarizer type weight indicators that have pad type load cells to directly sense mast loads. Each weight indictor is shipped with 10 dials so moving it from rig to rig is easy and by...

Dynamic HPHT filtration testing determines if fluid is properly conditioned to drill through permeable formations. Test results include two numbers: the dynamic filtration rate and the cake deposition index (CDI). The dynamic filtration rate is calculated from the slope of the curve of volume versus time. The CDI is calculated from the slope ofthe curve of volume/time ve...

Density is a measurement of fluid weight per unit of volume. This measurement is often referred to as mud weight and is reported as Gravity gms/cm3 or as Specific gallon, pounds, the primary function of monitoring density is to control formation pressures and minimize loss of returns. Pressurized Mud Balance Features • Field convertible from atmospheric to pressur...

The Permeability Plugging Apparatus (PPA) is a high pressure, high temperature instrument designed to simulate downhole static filtration .The PPA perates at temperatures and pressures that represent well conditions ,and the filtration medium is positioned above the sample fluid. The maximum test pressure is 5000psi(34,473kPa).And the maximum temperature is 500°F(260°C)...

Filtration characteristics of an oil mud are affected by the quantity, type and size of solid particles and emulsified water in the mud and by properties of the liquid phase. Interactions of these various components may be influenced by temperature and pressure. Therefore, filtration tests are often performed at both ambient temperature and at high-temperature conditions...

When a series of tests is needed at the drilling site, Rigchina Porta Lab includes the entire range of instruments necessary to measure the parameters of a successful drilling fluid operation. The kits are enclosed in rugged, durable cases, built to withstand harsh conditions.

The RIGCHINA Model RCLT-212 Combination EP (Extreme Pressure) and Lubricity Tester is a high-quality instrument designed to measure the lubricating quality of drilling fluids, provide data to evaluate the type and quantity of lubricating additives that may be required, and predict wear rates of mechanical parts in known fluid systems. EP tests are performed by applying ...

The UCA system consists of the following: 1. Processor, control software, monitor, and keyboard 2. Pressure controller 3. Autoclave Application The UCA continuously monitors the strength development trend of cement compositions while the cement is curing. The user can determine the initial set time and the wait-on-cement (WOC) time of cement slurry. This test data...
