Drilling Fluid Design Enlarges the Hydraulic Operating Windows of Managed Pressure Drilling Operations

Autor: Lee Conn, Douglas Oakley

Publikováno v: All Days.

With the increasing use of Managed Pressure Drilling (MPD) to mechanically control bottomhole pressures for drilling narrow mud-weight windows, little consideration has been given until recently to integrating drilling fluid design and MPD operations

How Effective is Current Solids Control Equipment for Drilling Fluids Weighted with Micron-Sized Weight Material?

Autor: Colin Bremner, Douglas Oakley, Shannon K. Stocks, Jarrod Massam

Publikováno v: All Days.

Centrifuges and shakers are the first defense when managing a drilling fluid against wellbore cuttings and solids contamination. The buildup of drill solids in a fluid can have a detrimental effect on its performance and properties. Much of the solid

Copper catalysed reactions of di-t-butyl peroxide: oxidative carbonylation of alcohols to give dialkyl carbonates, oxalates, or succinates

Autor: Douglas Oakley, George E. Morris, David A. Pippard, David J. H. Smith

Publikováno v: Journal of the Chemical Society, Chemical Communications. :410

Di-t-butyl peroxide, (ButO)2 is an efficient and convenient oxidant in the copper(I) chloride or copper(I) chloride–palladium(II) acetylacetonate catalysed oxidative carbonylation of alcohols to dialkyl carbonate, oxalate, or succinate esters.

Copper catalysed reactions of di-t-butyl peroxide: evidence for copper(II) alkoxide intermediates and a non-radical reaction mechanism

Autor: David J. H. Smith, George E. Morris, David A. Pippard, Douglas Oakley

Publikováno v: Journal of the Chemical Society, Chemical Communications. :411

Reaction of di-t-butyl peroxide, (ButO)2, with CuI chloride species gives CuII alkoxy chlorides which are intermediates in the oxidative carbonylation reaction of alcohols to dialkyl carbonate, oxalate, or succinate esters and evidence is presented t
