ABSTRACT. Drilling fluids are, among other things, expected to transport cuttings and control fluid loss. The rheology of drilling fluids plays an important roll in both of these aspects of drilling fluid performance. A number of years ago the American Petroleum Institute established a set of standards for evaluating the rheology of drilling …

The mud standpipe manifold is installed downstream of the mud pumps with the purpose of diverting the flow of drilling fluids toward the drill line or drillstring. An adjustable choke can be installed to bleed pressure off the drillpipe, to reduce shock when breaking circulation in wells where loss of circulation is a problem, and to bleed off ...

This project aimed at formulation of bentonite drilling mud using local bentonite clay. Barite and moldstar (starch) as additives. The research work was carried out to produce a mud that will serve as best alternative to the drilling operation, and find out the best proportion of bentonite (clay), barite and moldstar (starch) for the formulation of …
drilling fluid was measured for rheology, ES, barite sag and HTHP fluid loss. Results and Discussion I. Abrasion The first series of abrasion tests was performed using the abrasion test method in API RP 13I. For testing, hematite and ilmenite were first ground to near API barite particle sizes and the abrasion compared to API-grade barite.
This study proffers an alternative to the importation of drilling mud and shows an experimental approach on the preparation of drilling mud with readily available locally …

A thick mud cake across porous zones can be easily formed because the drilling mud has high fluid loss values. The thicker the mud cake is, the more torque and drag are experienced while performing the drilling and tripping operations. References. Andy Philips, 2012. So You Want to be a Mud Engineer: An Introduction to Drilling …
API filtrate on a mud report is a method of evaluating how close the mud samples taken from a drilling operation are to the target density. The American Petroleum Institute (API) assigns a number that corresponds to the mud's density, which is then used to evaluate the accuracy of the mud sample.
minimal API requirement for drilling mud, the plastic viscosity(PV) is also above the API requirement, therefore the mud system that was not able to be used for drilling has successively been improved by just the addition of 20g of ginger which can now be used for drilling. It could be observed from Figure 2 that the gel strength improved ...
