Title: Real-time fluid contamination prediction using bilinear programming
Inventor: HAMED CHOK
IPC: G01N33/28
Filed: 2017-03-21
Abstract: A wellbore fluid comprises unknown fractions of a formation fluid and a filtrate fluid, each of unknown composition. Method 200 comprises receiving a sequence of measurements of a wellbore fluid (step 210), obtaining constraints on a sequence of filtrate fractions (230), performing a constrained bilinear optimisation (240) that minimises total measurement error over the measurement sequence subject to obtained constraints, computing minimum and maximum optimal values for the filtrate fraction (250), and providing these to a well operator (260). Measurements may be spectroscopic measurements of the filtrate and/or formation fluid, density measurements or refractive index measurements. Spectra may lie in a linear polyhedral space. Constraints may be based on initial conditions, or be temporal, and may be linear or bilinear. Advantageously, predicting fluid formation fluid purity in real time allows the operator to guide the physical sampling process, eg by forecasting a time before filtrate fraction drops below a threshold.

Title: Commit window move element
Inventor: MICHAEL JOHN GIBBS
IPC: G06F11/34
Filed: 2018-01-25
Abstract: A trace module has monitoring circuitry for monitoring processing of instructions by processing circuitry, and trace output circuitry for outputting a sequence of elements indicating outcomes of the processing of instructions by the processor. The trace module can output a commit window move element (CWM) indicating that a commit window 52, representing a portion of the trace stream comprising at least one speculative element representing at least one speculatively executed instruction, should move while the oldest remaining speculative element 70 of the trace stream remains uncommitted. This is useful for tracing of long-lived speculation events such as transactional memory functionality or long latency load/store instructions. Removing such elements from the commit window allows other speculative elements to be implicitly committed (by considering commit window maximum speculation depth 51), without needing to output a commit element (which explicitly commits the oldest speculative element in the commit window).

Title: Multi-phase flow-monitoring with an optical fiber distributed acoustic sensor
Inventor: Mohammad Amir
IPC: G01N29/46
Filed: 2016-08-05
Abstract: Embodiments of the invention provide a "tool-kit" of processing techniques which can be employed in different combinations depending on the circumstances to monitor multiphase flow in a structure such as a pipe. For example, flow speed can be found using eddy tracking techniques or by using speed of sound measurements. Moreover, composition can be found by using speed of sound measurements and also by looking for turning points in the k-omega {k-ω) curves, particularly in stratified multiphase flows. Different combinations of the embodiments to be described can therefore be put together to meet particular flow sensing requirements, both on the surface and downhole. Once the flow speed is known, then at least in the case of a single phase flow, the flow speed can be multiplied by the interior cross-sectional area of the pipe to obtain the flow rate. The mass flow rate can then be obtained if the density of the fluid is known, for example once the composition has been determined.

Alternatively, wellbore fluid can be directed into the heating chamber (118, fig 2A) via a port or propeller to directly heat wellbore fluid; in this embodiment (fig 2A, 2B) the heater pumps the wellbore fluid. The fins 242, 244 can be elongate with rectangular planar end tips; grooves between fins are V-shaped interstices 243 defined within the heating chamber. The fins 242, 244 can be curved, undulating or helical to aid fluid movement along the flow path 30. An external housing 223 can define a fluid flow path 230 with a fluid outlet and nozzle (125, fig 2B). A grinder (138, fig 2B) or sand cone crushes trapped particles in the fluid.
