C09K 8/12

US Classification:

175 72, 1663051, 175 65, 507123, 507130, 507131, 507229, 507242, 507244, 507910

Abstract:

The present invention relates to subterranean treatment fluids. In particular, the present invention relates to subterranean treatment fluid compositions that comprise polyoxazoline compositions and methods for using such compositions in subterranean applications. In one embodiment, the present invention provides a method of controlling shale swelling in a subterranean formation comprising introducing a treatment fluid into the subterranean formation, wherein the treatment fluid comprises a base fluid and a polyoxazoline composition. In another embodiment, the present invention provides a method of treating a portion of a subterranean formation comprising the steps of: introducing a treatment fluid that comprises a base fluid and a polyoxazoline composition; and treating a portion of the subterranean formation. Other embodiments are provided.

Filed:

Oct 6, 2005

Appl. No.:

11/244801

Inventors:

Stephen A. Bell - Houston TX, US
William W. Shumway - Houston TX, US

Assignee:

Halliburton Energy Services, Inc. - Duncan OK

International Classification:

C09K 8/24
C09K 8/05

Abstract:

Metal cross-linked phosphate ester compositions impart fragile progressive gel structure to a variety of oil and invert emulsion-based drilling fluids at neutral or acidic pH. The fluids are useful for drilling wellbores in subterranean formations without need for organophilic clays to suspend drill solids. At greater concentrations, metal cross-linked phosphate ester compositions enhance fluid viscosity for suspending weighting materials in drilling fluids during transport of the fluids, as from a manufacturing or mixing facility to a drilling site.

Peter Masak - West Chester PA, US

International Classification:

G01N033/03

US Classification:

436060000, 436173000

Abstract:

A method and composition for distinguishing native hydrocarbons in a formation from oil-based drilling fluid with nuclear magnetic resonance (NMR) is provided so that NMR may be used in analyzing formation fluids from boreholes drilled with oil-based drilling fluids. In the method, the drilling fluid is doped with oil solubilized paramagnetic species before or during drilling of the borehole. The paramagnetic species cause a shift in the Tand TNMR response of the drilling fluid.

Filed:

Jul 13, 2004

Appl. No.:

10/889739

Inventors:

Stephen Bell - Houston TX, US

International Classification:

B01D 15/08

US Classification:

210656000, 436161000, 210635000

Abstract:

The present invention relates to the separation of components in treatment fluids. More particularly, the present invention relates to the use of a field test that comprises separating components of treatment fluids that have varying molecular weights. In some embodiments, the present invention provides methods of separating components from a sample of a treatment fluid as part of a field test that comprise applying the sample of the treatment fluid to a chromatographic column, wherein the sample comprises components having varying molecular weights; and applying an eluent to the chromatographic column so as to separate the components as part of a field test. In other embodiments, the present invention provides methods of determining the composition of a treatment fluid
