Completions
HCl acid stimulation of carbonate production requires the retardation of the HCl-carbonate rock reaction to achieve the optimum balance between total fluid used and the enhancement of well production. The described investigation was done offshore Sarawak using Indiana Limestone cores.
The newly formed SPE Hydraulic Fracturing Technical Section is working on a project to identify a set of best practices for completions engineers. Once completed, they will be accessible to the entire SPE technical community.
Mixing dry polymer powder and water to make friction reducer as needed during fracturing can cut the cost of the additive and the testing of whether a drastically simplified recipe performs as well as more-complex mixes.

Flow rate is a major challenge for geothermal. However, the techniques used in shale to prevent flow localization can be applied directly to geothermal. If we can create hundreds or thousands of flowing fracture pathways around a horizontal or deviated geothermal well, then we will have truly “changed the game.” -
This paper presents the lessons learned from optimizing sand control and management strategies of an offshore sandstone oil field offshore Nigeria after multiple sanding events and well failures.
-
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.
-
Few industries contain as many phases, steps, and levels of interface between the start and end product as the oil and gas industry. It therefore is hardly surprising that communication, in all its varied forms, is at the very heart of our business.

Electric-powered fracturing fleets looked impressively resilient in 2020 amid what was otherwise a significant collapse for the hydraulic fracturing sector. Today, the situation is more complicated.
-
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.

SponsoredOriented perforating is an increasingly adopted practice for new well completions. But how to ensure these perforations are correctly aligned? Impact Selector’s Relative Bearing Tool focuses on downhole tool orientation and has an outstanding track record in identifying gun direction prior to shooting.

Using electricity to run oilfield operations is supposed to make everything better, but just getting the power needed is a challenge.
-
Hiber, an industrial Internet-of-Things startup, announced that it has signed an agreement with Shell to provide well-integrity monitoring solutions globally.

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.
