... of the latest deployment methods, specifically a pump-down dissolvable, single-use fiber optic cable. This is a cost effective and minimal footprint option for data collection. This project included three acquisition methods for the DAS: 1) a permanent fiber optic line cemented on the outside of the casing, 2...

... operations in real-time. However, most of the digitalization effort to date has been focused on increasing operational efficiency to reduce cost. Without an equal consideration for creating effective fracture geometries, this may lead to poor resource recovery and leave significant value behind...

..., the frac placement distribution effectiveness was worse after the deployment of the diverter material. All the tested stages showed the expected treatment pressure increase at the surface corresponding to the "pods" blocking some of the perforations. It is important to highlight that in the absence...

... Abstract The industry continues to face a challenge understanding and optimizing completion strategies to minimize the impact of infill development on existing wells and achieve larger Stimulated Reservoir Volume (SRV) on infill wells. This paper presents a cost-effective technique...

... Evaluating effectiveness of diversion has typically relied on two legacy diagnostic methods – 1) using treatment pressure analysis – looking for surface treatment pressure changes associated with the diverter drop and 2) chemical or radioactive tracers before and after a diverter drop. Using...

... the barrier layer is crossed. A toughness/modulus barrier, on the other hand, results in an immediate sharp increase in fluid pressure followed by gradual decline in pressure. The effect of individual sliding interfaces is similar to that of a toughness/modulus barrier. The cumulative effect becomes more...
