International Classification:

E21B 4700

US Classification:

16625012, 166264, 166186

Abstract:

Methods and apparatus are provided which permit well testing operations to be performed downhole in a subterranean well. In various described methods, fluids flowed from a formation during a test may be disposed of downhole by injecting the fluids into the formation from which they were produced, or by injecting the fluids into another formation. In several of the embodiments of the invention, apparatus utilized in the methods permit convenient retrieval of samples of the formation fluids and provide enhanced data acquisition for monitoring of the test and for evaluation of the formation fluids.

Filed:

Aug 27, 2003

Appl. No.:

10/648977

Inventors:

Paul D. Ringgenberg - Frisco TX, US
Gregory N. Gilbert - Sugar Land TX, US

Assignee:

Halliburton Energy Services, Inc. - Houston TX

International Classification:

G01N001/00

US Classification:

7386461, 7315223

Abstract:

A single phase sampling apparatus and method for retrieving a formation fluid sample at or above the bubble point of the sample. The apparatus utilizes a gas charge contained between a sample piston and a charging piston to maintain a formation sample at the desired pressure. The charging piston utilizes the hydrostatic pressure present at the depth of the desired formation sample to compress and therefore increase the gas charge to the appropriate pressure necessary to maintain the formation sample at the desired pressure. The utilization of hydrostatic pressure to increase the pressure of the gas charge allows the use of a low pressure gas charging system to prepare the apparatus prior to sampling, thereby increasing the safety and ease of use of the device.

Appl. No.:

10/837764

Inventors:

Mark A. Proett - Houston TX, US
Gregory N. Gilbert - Sugar Land TX, US
David E. Ball - Stafford TX, US

Assignee:

Halliburton Energy Services, Inc. - Houston TX

International Classification:

G06F 19/00

US Classification:

175 65, 73155, 702 1

Abstract:

Methods for operating multi-probed formation testers to determine a fluid density gradient in the formation. The probes of the multi-probed formation tester are connected to a pressure gauge through a flowline that establishes a differential height between the probes. In some embodiments, a gradient of the fluid density in the flowline is determined as a function of the gradient of fluid density in the wellbore. The flowline fluid density gradient is then used to determine a formation fluid density gradient as a function of the flowline fluid density gradient.
