Filed:

Jul 20, 2001

Appl. No.:

09/910424

Inventors:

Michael A. Freeman - Kingwood TX

Assignee:

M-I, L.L.C. - Houston TX

International Classification:

E21B 3708

US Classification:

175 66, 507110

Abstract:

The present invention relates to the use of a buffered acid wash to reduce the amount of oil in cuttings associated with the use of an invert emulsion well fluid. The buffered acid wash is sufficiently acidic as to convert all of the surfactant in the invert oil emulsion from one charge species into another, but substantially prevents the fluid from becoming so acidic as to generate carbon dioxide.

Abstract:

Disclosed are methods and related compositions for altering the physical and chemical properties of a substrate used in hydrocarbon exploitation, such as in downhole drilling operations. In a preferred embodiment a method involves formulating a fluid, tailored to the specific drilling conditions, that contains one or more inactivated enzymes. Preferably the enzyme is inactivated by encapsulation in a pH responsive material. After the fluid has been introduced into the well bore, one or more triggering signals, such as a change in pH, is applied to the fluid that will activate or reactivate the inactivated enzyme, preferably by causing it to be released by the encapsulation material. The reactivated enzyme is capable of selectively acting upon a substrate located downhole to bring about the desired change in the chemical or physical properties of the substrate.

Assignee:

M-I L.L.C. - Houston TX

International Classification:

G01N 33/487

US Classification:

73 5301

Abstract:

An apparatus and method for testing fluids to be used when drilling in unconsolidated sand formations includes a container having a first port and a second port and a plurality of perforations through which fluid can be communicated, a bore holder slidingly retained through a portion of the container between the first port and the second port, wherein the bore holder has a feed end and a discharge end, a bed of unconsolidated sand contained in the container in a compacted state surrounding the bore holder, a fluid distribution nozzle at the discharge end of the bore holder, a fluid source in fluid communication with the discharge end of the bore holder, wherein the fluid source provides a test fluid to the fluid distribution nozzle through the bore holder, wherein the bore holder is withdrawn from the container at a predetermined speed as the test fluid is communicated through the fluid distribution nozzle, thereby leaving a simulated well bore in the unconsolidated sand.

Abstract:

The present invention provides a system for reducing entrained and dissolved gasses from a well fluid. The system includes a well fluid, at least one process tank into which the well fluid flows, wherein a first process tank comprises a weir arrangement over which the well fluid spills, a mechanical degasser coupled to the at least one process tank and configured to receive the well fluid, and an aeration device disposed in the at least one process tank that generates bubbles in the well fluid. The present invention also provides a method of reducing entrained and dissolved gases from a well fluid that includes flowing a well fluid into a process tank, exerting a centrifugal force on the well fluid, and generating bubbles in the well fluid in the process tank.
