Unconventional/complex reservoirs
The $100-billion project is widely considered the largest unconventional development outside of the US and is noted by Aramco as the largest nonassociated gas development in the kingdom.
This paper presents a study of trapped-torque incidents during drillpipe connection, highlighting contributing factors and root causes and proposing prevention and mitigation measures for these transient events.
In this study, a method was developed to analyze the effects of drilling through transitions on bit-cutting structures and construct an ideal drilling strategy using a detailed drilling model.

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.
-
This paper presents an integrated work flow to model mechanical properties at sufficiently high resolution to honor accurately rock fabric and its effects on height and complexity and, thus, production.
-
The US producer also closed its acquisition of assets in the Permian through a deal with Primexx.
-
The gas-focused producer said it will turn its attention to drilling programs on its Haynesville acreage.

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.
