Unconventional/complex reservoirs
The merger creates one of the largest oil-focused independents in the US with output of 526,000 BOE/D.
BPX Energy will retain operatorship of the assets after the sale of its interests to private investment firm Sixth Street is complete.
This paper describes development of a high-temperature water-based reservoir drill-in fluid using a novel synthetic polymer and customized with optimal chemical concentrations and sized calcium carbonate.

SponsoredUnconventional wells produce massive amounts of data across a multitude of systems. Bringing all this data together increases efficiency, speeds screening, enhances smart decision-making, and ultimately returns greater production. Learn how PetroVisor can help. -
This paper describes a technology with the capability to map and detect lithology changes ahead of the bit in real time.
-
Friction reducers play multiple critical roles in fracturing. A challenge in selecting the best one for the job is the growing evidence that performance varies, but objective performance measurements are lacking.
-
The paper describes an integrated work flow to apply autonomous inflow-control devices successfully in an offshore heavy-oil reservoir with significant uncertainty in remaining oil thickness and water/oil contacts.
-
This paper details new technologies and work flows implemented for Australian offshore wells to improve drilling efficiency while managing associated risks.
-
The paper demonstrates the application of an interpretable machine-learning work flow using surface drilling data to identify fracable, brittle, and productive rock intervals along horizontal laterals in the Marcellus shale.

This paper describes the findings of a root-cause analysis of wellhead-penetrator failures in Canadian steam-assisted gravity-drainage operations and the mitigation measures taken.
-
The obsession with better hydraulic fracturing has steadily pushed on shale production in year one, but the decline remains steep. Chemistry could help explain, and perhaps extend, the short productive life of these wells.
-
The authors develop and apply a laboratory protocol mimicking leakoff, shut-in, and flowback processes to evaluate the effects of fracturing-fluid additives on oil regained permeability.

Recent history has taught the unconventional sector that overly optimistic production forecasts can backfire. Going forward, one solution may be to combine financial and subsurface models to better communicate expectations.
