Membrane systems are parallel and bioinspired systems which simúlate membranes behavior when processing information. As a part of unconventional computing, P-systems are proven to be effective in solving complex problems. A software technique is presented here that obtain good results when dealing with such problems. The rules application phase is studied and updated accordingly to obtain the d...

Well testing is of great importance in petroleum engineering, to have a kind of firsthand knowledge and estimating formation permeability, wellbore damage/ skin, etc. These parameters are further required to estimate production rate from a well and at the same time gives an idea of its productivity. These reservoir related parameters calculation is strongly dependent on formation thickness. Any...

This is the fourth in a series of 5 articles providing a contemporary overview and introduction to unconventional dentistry (UD) and its correlation to unconventional medicine (UM). Several common UD and UM practices are described to familiarize practitioners with a variety of theories, practices, products and treatments that specifically apply to dentistry. This brief review is not intended as...

The geological storage of CO2 is a critical technique for reducing emissions, which significantly contributes to the mitigation greenhouse effect. Currently, often geologically stored in coal seams, hydrocarbon reservoirs, and saline aquifers order store improve oil gas recovery simultaneously. Shale formations, as candidates storage, are drawing more attention because their rich volumes. throu...

This paper reports on the outcomes of an approach to granular synthesis using the biological computing substrate Physarum polycephalum. The plasmodium of Physarum Polycephalum is unicellular with a myriad of diploid nuclei, which moves like a giant amoeba in its pursuit of food. The organism is amorphous, and although without a brain or any serving centre of control, can respond to the environm...

Abstract Pore pressure is a crucial factor affecting reservoir stimulation, especially in unconventional reservoirs, because it can control crack initiation and propagation. However, studies on the effect of initial pore hydraulic fracturing low-permeability reservoirs are lacking, mechanism remains unclear. Therefore, we conducted tests under pressure, proposed an improved criterion to elucida...

Horizontal wellswith multi-cluster fracturing technology is an effective approach to exploit unconventional hydrocarbon reservoirs. The on-site diagnosis results indicate that fractures always tend propagate unevenly due stressinterference, therefore it very essential study the effect of parameters on fracture propagation unevenness. In this paper, model (UFM, Unconventional Fracturing Model) u...

INA d.d. has carried out systematic hydrocarbon exploration in Croatia since 1952. In the last 62 years it resulted in the discovery of 57 onshore oil and gas fields and 17 offshore gas fields, i.e. 1.4 billion boe of hydrocarbon reserves of which 1.2 billion boe was recovered. The Pannonian Basin can be considered a relatively well explored area where remaining potential should be looked for i...

Hydraulic fracture is crucial for assuring well production from unconventional reservoirs. For the optimization of hydraulic geometry and ensuing an interlayered reservoir, vertical propagation path has been analyzed. However, effective fluid channel cannot be formed if proppant unable to reach area where propagates. This paper presents a numerical model using lattice-based method investigate t...
