“…So Almedallah et al have presented an integrated model that combines surface and subsurface infrastructure design. The model uses a Monte Carlo Markov chain method to explore the field connectivity, coupled with an optimization routine based on a detailed cost model to determine facility placement (Almedallah and Walsh 2019). But the main differences between this paper and previous works are: Sensitivity analysis which examine the contribution of each parameter on target function.…”

An integrated model of the PUNQ-S3 reservoir in the North Sea was constructed. Then, 16 parameters with the highest impact on target functions were selected for sensitivity analysis. The sensitivity analysis was based on the two-level Plackett-Burman design of experimental method. Finally, seven variables with the highest impact on the target functions were selected. Net present value, cumulative oil production, and cumulative water production were three target functions. The proxy model was constructed using the three-level Box-Behnken experimental design for each of the three target functions, taking into account the effect of the variable's interactions on each other. Then the compliance and predictivity of the proxy model for each target function were validated according to the decision variables. In the end, multiobjective optimization was conducted with the aim of maximizing net present value and cumulative oil production and minimizing cumulative water production using a parameter called composite desirability.

“…Up to now, most of the oil and gas resources are developed from the shallow rock formations [1] . With the rapid consumption of energy, the oilwell drilling techniques are toward to the deep and ultra-deep formations [2,3] , which increases the need of drilling techniques and equipment for the deep formation.…”

For a drill bit, the cutter is the most important part to break the rock. In oilwell drilling, polycrystalline diamond compact (PDC) bit is widely used to shear the rock formation. In this paper, a finite element model with including the axe-shaped PDC cutter and rock formation is developed to study the rock breaking behaviours. Results show that the effect of axe-shaped PDC cutter on rock breaking is better than that of the planar PDC cutter. The front rake angle and face angel play significant role on the axial force but have little influence on the tangential force. In addition, both the tangential force and axial force increase rapidly with increasing the depth of cut.

“…175 km off the east coast of Aberdeen (Thomas et al, 1974), which has been in production for 45 years with no sign of nearing its end of commercial life. Furthermore, while new O&G fields are being discovered in ultra‐deep water of >1,500 m (Chakrabarti et al, 2005; Hu et al, 2013), it is a little‐known fact that shallow‐water construction of new O&G infrastructure continues annually (Almedallah & Walsh, 2019). Moreover, the current and ongoing war between Russia and the Ukraine has induced European O&G shortages, so new North and Irish Sea Exploration & Production (E&P) licenses are being issued on a regular basis.…”

Offshore Oil and Gas (O&G) exploration and production has been cycling from cradle to grave for over 100 years, spanning many generations of marine fauna. Despite global occurrence of offshore infrastructure, implications of their presence for apex predators, including cetaceans, is understudied. We analyzed data from autonomous underwater passive‐echolocation‐click detectors (C‐PODs) deployed at an offshore O&G production platform and at control locations to investigate acoustic activity of harbor porpoises (Phocoena phocoena) from 2015 to 2020, before, during, and after platform construction. Despite a statistically significant decrease in porpoise detections following platform construction and initial drilling operations (2015–2016), detections returned to baseline levels within five months. We detected no long‐term effects of platform presence on porpoise‐detection rates. While additional study is required to further understand activity of porpoise at O&G platforms during continued operation through to decommissioning, our findings, nonetheless, have important implications for Environmental Impact Assessments (EIAs), which do not currently consider effects of platform presence on marine mammals in any context other than short‐term noise mitigation. While we know porpoise forage at ageing platforms, this is the first study to demonstrate porpoise also utilize space around new platforms, which must be accommodated in long‐term EIA processes.
