Rotary Steerable Drilling Fluid

SPE Asia Pacific Oil and Gas Conference and Exhibition, 2001
AbstractNew mud chemistry is shown to improve the efficiency of directional drilling with a rotary steerable drilling system. Full-scale (8½-in. bit) drilling results using a rotary steerable drilling system drilling to horizontal at an experimental test site and an application in the Huizhou 21-1 field, offshore Hong Kong in the South China Sea are ...

The Characterization of a Drilling Fluid Additive

Proceedings of SPE/IADC Drilling Conference, 1988
Abstract The guidelines for selection of a drilling fluid additive have changed during the past few years. No longer is performance the only criterion to characterize an additive. Demands on the drilling mud specialist to select the correct additive comes not only from drilling personnel, but also from explorationists, production ...

Characteristics of Drilling Fluids

Transactions of the AIME, 1931
To properly account for the various characteristics of drilling mudsobtained in different areas and geological horizons, it is necessary to studythe composition of the mud from a chemical and physical standpoint asdetermined by the proportions and activities of the various solid contituentsthat are present in various states of division ...

Selecting a Drilling Fluid

Journal of Petroleum Technology, 1990
" Although acceptable substitutes have been developed for some additives, the search for adequate replacements for environmentally objectionable systemscontinues to be the highest research priority in drilling priority in drillingfluids." Introduction Selection of the proper drilling fluid is ...

Drilling Fluid Disposal System

Proceedings of SPE/IADC Drilling Conference, 1995
Abstract A superior method of downhole annular disposal of drilling mud waste has been developed utilizing external casing packers and a modified port collar to isolate a predetermined disposal zone. The benefits of this system are that it reduces the risk of contamination of fresh (potable) water sources and greatly reduces the risk of ...

A Multifunctional Drilling Fluid for Coalbed Methane Drilling

Advanced Materials Research, 2012
With extremely complicated geological conditions, there is abundant coalbed methane in the China's Ordos Basin Area. As a result of coexistence of different pressure systems in the same one naked well section, there are so many problems taking place occasionally during the drilling process, such as the formation lost circulation and collapse, which ...

Particulate Invasion From Drilling Fluids

Proceedings of SPE European Formation Damage Conference, 1999
Abstract Particulate invasion is one of the primary mechanisms of formation damage caused by drilling fluids. During the initial stages of filtercake growth particles are forced into the formation, building an internal filtercake which plugs the near surface pores.

How To Manage Drill-In Fluid Composition To Minimize Fluid Losses During Drilling Operations

SPE/IADC Middle East Drilling Technology Conference, 1999
Abstract Selection of the best Drill-in Fluid for drilling horizontal wells is based, essentially, on the characteristics of the filter cake formed near wellbore region. Minimizing filtrate loss into the formation by forming a thin filter cake with low porosity and permeability is the key to managing formation damage problems.
