pH In drilling mud is one of the major mud properties for monitoring as it had an effect on clay interactions, corrosion processes and solubility of certain chemicals. Drilling Mud pH can be measured using pH Strips or a pH Meter, as follows. According to above, we will present the steps of PH in drilling …
The following drilling mud testing equipment & procedures have been standardized by internationally accepted ANSI/ API RP 13B-1 Fourth Edition, March 2009 (Recommended Practice for Field Testing Water-Based Drilling Fluids), which is identical to ISO 10414-1: 2008 (Field Testing of Drilling Fluids Part 1 for Water-Based Mud). But first, before going in-depth on our subject, …
Precautions must be taken when performing mud checks because dangerous chemicals are often used and some of the mud testing equipment is subjected to high temperatures and pressures. Some basic rules for the mud lab are as follows:- IADC Safety Alert: Catastrophic Failure of 50 cc Retorts This alert was released following two catastrophic failures …
The following Marsh funnel viscosity test procedure is used for measuring funnel viscosity for Water Based Mud, Oil Based Mud, or completion fluid: Calibration checks should be made periodically, using the procedure detailed above, by filling the Marsh Funnel with fresh water and recording the time to discharge 1 quart of water, which should take …
Sand Content Kit A sand content kit is used for measuring the sand content in water-based drilling mud or oil-based drilling mud, comprising a 200-mesh sieve, a plastic funnel, and a graduated glass tube that is calibrated to measure the sand content as a percentage. The 200-mesh sieve is designed to trap particles that are …
Several procedures are available for improving mud displacements in any oil rig or gas rig and they need to be considered when planning a displacement in order to prevent or minimize fluid contamination. However, operational factors may restrict the use of some of the following procedures: 1 Direct and Indirect Mud / Fluid Displacements The …
In this article, we will talk about the benefits of using Oil Based Drilling Fluid in drilling operations, but first, please don’t forget to subscribe with us. The most common type of oil-based fluid system is the inverted emulsion fluid system, where a water-in-oil micro-emulsion is formed between a brine phase and the oil phase, including the …
What Is The Drilling Fluid Test HPHT Filter Press? The HPHT filter press fluid loss test, which is differ from API filter press fluid loss test, is used for measuring fluid loss for all types of drilling fluids at elevated temperature and pressure. A sample of mud is pressurized in a chamb er while the …
Shale has become a significant challenge for the oil and gas industry due to its sensitivity to drilling activities. It is susceptible to wellbore instability, bit balling, and dispersion of shale particles in drilling fluids. Over the years, many oil and gas companies developed various types of shale inhibitors to overcome the shale problems. The …
The low-temperature API filter press, operated at room temperature and low pressure, is used for measuring fluid loss only with Water Based Mud. In brief, the API filter press test procedure pressurizes a sample of mud in a chamber while the volume of filtrate that passes through filter paper over a specified period is measured. The …
