BHGE’s Perception of Industry Imperatives

Oil and Gas Operating Companies work in a market constrained by, at best, revenue uncertainty and, currently, low product prices.

They are under financial constraints to maximise cash flow and return on capital like rarely before.

FID approvals for new, multi-decade developments remain hard to justify; placing the onus on preserving production and well integrity for existing assets.

These assets also must be decommissioned at the absolute minimum cost consistent with industry and regulatory standards.

This situation requires existing assets’ life cycles (reservoirs as well as well infrastructure) to be optimised and every Dollar of both CAPEX and OPEX spent

wisely through data-driven decisions and planning.

Well Integrity Production Logging SlicklineThe widest measurements portfolio in the industry. Providing answers to your cement uncertainties utilizing three different measurements. With the ability to identify tubulars & casing conditions up to 5 barriers.

Tubing & Casing Cutters Reservoir monitoring DeploymentThe BHGE tubing and casing cutting arsenal is the biggest in the industry. The Mechanical Pipe Cutter (MPC) along with the Downhole Electric Cutting Tool (DECT) provides the flexibility to have clean cuts from 2 7/8” tubulars to 7 5/8” casings.

We have listened to our clients’ concerns regarding issues associated with the current available production logging platforms. BHGE utilized the Industry recognized MAPS to build our future production logging Platform Accuphase®

The RPM® Platform address a broad scope of reservoir evaluation and management applications, including reservoir saturation and produced fluids monitoring, formation evaluation, production profiling, workover and well abandonment evaluation, borehole diagnostics, location of bypassed oil, gas detection and quantification, and identification of water production.

SondeTrax® is our new wireline tractor used in the deployment & retrieval of the wireline tools. Higher efficiencies & tandem tractoring options.

Whether it is an intervention job with Slickline or a SRO is required for PLT, BHGE offers a wide range of modularity and options to satisfy our clients’ needs.

Field-trial locations

• Shorter toolstring enabling safer operations

• Possible multiple tools combination for a better borehole coverage

• Log data is improved through robust, co-located sensors on the arms and the new optical sensor for gas detection

• Independent deployment arms increase cross-sectional coverage and tolerance to decentralizationty

• Improved sensor distribution and more precise borehole coverage increasescalculation reliability

Gas array optical sensors

Depending on the refractive index of the fluid medium, light either refracts into the medium (liquid), or reflects back (gas).
