The present disclosure relates to methods and apparatuses for acquiring multi-component gravity information for an earth formation. More particularly, the present disclosure relates to estimating the movement of fluid in an earth formation using at least one gravimeter configured to generate multi-component gravity information. The method may include estimating density changes in the earth formation. The method may include estimating a position of the at least one gravimeter. The apparatus may include a multi- component gravimeter configured to estimate gravity vectors for each vector component.

Characterizing a parameter of interest relating to a formation intersected by a borehole. Methods may include estimating the parameter using at least one gravity measurement adjusted to account for a gravity field gradient associated with a change in a frame of reference caused by removal of a reference feature from the borehole. Methods may also include taking at least one prior gravity measurement before removal of the reference feature from the borehole; taking at least one prior gravity measurement after removal of the reference feature from the borehole; estimating the change in the frame of reference based on the prior gravity measurements taken before and after removal of the reference feature; and adjusting the at least one gravity measurement using the estimated change.

Estimating molecular size distributions in formation fluid samples using a downhole NMR fluid analyzer

Номер: GB0002525358A

A method for estimating a property of subsurface material includes extracting a sample of the material using a downhole formation tester and performing a plurality of nuclear magnetic resonance (NMR) measurements on a sensitive volume in the sample where each measurement in the plurality is performed in a static homogeneous magnetic field with a pulsed magnetic field gradient that is different in magnitude from other NMR measurements to provide a waveform signal. The method further includes transforming each received waveform signal from a time domain into a frequency domain and comparing the frequency domain signal to a reference to provide proton chemical-shift information related to a chemical property of one or more molecules in the sample and transforming the frequency domain signals into a complex number domain that quantifies waveform signal amplitude changes to provide one or more diffusion rates with each diffusion rate being associated with a corresponding frequency.

Принадлежит:

An apparatus and method for estimating reservoir connectivity using gravity estimates at a fluid contact for each of two or more boreholes. The method may include identifying fluid contacts in the boreholes. The method may include additional gravity estimates at and/or between a well head and the fluid contact of each borehole. The method may include gravity estimates along a surface between well heads of the boreholes. The method may include estimating true vertical depth for the boreholes. The apparatus may include at least one gravimeter and a processor configured to estimate reservoir connectivity using estimates from the gravimeter.

Measurement method for a component of the gravity vector

Номер: GB0002490626A
Автор: EDWARDS CARL M [US], EDWARDS CARL M, CARL M EDWARDS
Принадлежит:

The present disclosure relates to methods and apparatuses for calibrating a sensor, particularly a gravimeter, which involves positioning the sensor in at least three different orientations and calibrating the sensor using a linear model and the sensor outputs from the at least three different orientations. The method may include applying an external force to the sensor. The apparatus includes a processor and storage subsystem with a program that, when executed, implements the method.

Temperature insensitive devices and methods for making same

Номер: GB0002488690A
Автор: EDWARDS CARL M [US], EDWARDS CARL M, CARL M EDWARDS
Принадлежит:

An apparatus and method for estimating a parameter of interest using a force responsive element comprising, at least in part, a balanced material. The balanced material is temperature insensitive over a specified range of temperatures such that the force responsive element may estimate the parameter of interest by responding to a desired force with relatively little interference due to temperature changes within the specified range of temperatures.
