Formation losses usually account for most of the additional costs when actual drilling fluid costs exceed estimated figures, which is why so much effort goes into preventing down-hole losses in the first place. If offset data is available, we can design the well to isolate lost-circulation zones behind casing pipe before drilling deeper formations requiring …
Cementing is the most important non-drilling function performed by the Drilling Foreman. Poor cementing properties & techniques used in oil and gas wells can cause countless drilling problems if the bottom joint of the surface pipe is lost. It can also cause costly remedial operations or loss of holes. A bad cement job can make …

This article is part of the significant article on drilling fluid test procedures. Oil-Based Mud Testing Procedures For Physical Properties These Oil Based Mud Testing Procedures For Physical Properties are as follows: Oil Base Mud Whole Mud …
Glycol is generally used in KCl-Polymer fluid systems when enhanced Shale Inhibition is required. Glycol will be lost through adsorption on exposed shale formations in the wellbore and on the cuttings, and the glycol depletion rate will be a function of the drilling Penetration Rate (ROP) and the Cuttings size. Therefore, the glycol concentration test …
Monitoring and controlling the potassium ion concentration for water based mud systems that use potassium for shale inhibition is important. It will deplete as it is adsorbed onto shales. Depletion must be monitored, and effective inhibition levels must be maintained in the mud system. The Potassium ion concentration is determined by adding excess Sodium Perchlorate …
Cation Exchange Capacity In Mud System This Methylene Blue Test Clay Content in drilling mud is used for measuring the Cation Exchange Capacity (CEC), which determines the reactive clays in the mud system. This article is one of the water-based drilling fluid testing procedures articles that handle the chemical testing of WBM. Equipment For Methylene …
