Lost circulation has become a crucial technical problem that restricts the quality and
efficiency improvement of the drilling operation in deep oil and gas wells. The lost-circulation …

Lost circulation is one of the frequent challenges encountered during the drilling of oil and
gas wells. It is detrimental because it can not only increase non-productive time and …

Buffer solutions have tremendous importance in biological systems and in formulated
products. Whilst the pH response upon acid/base addition to a mixture containing a single …

Predicting the rate of penetration (ROP) is a significant factor in drilling optimization and
minimizing expensive drilling costs. However, due to the geological uncertainty and many …

In this paper a predictive control method based on decentralized fuzzy inference (DFIPC) is
proposed to deal with the problems of strong nonlinearity, large hysteresis and uncertainty in …

Gluconacetobacter diazotrophicus is an endophytic bacterium that has shown important
plant growth-promoting properties. During the growth of G. diazotrophicus with high carbon …

This paper reports the experimental results of a predictive controller applied to a pH
neutralization plant. A pretest was used to get an approximate transfer function (first order …

In the continuous manufacturing of pharmaceuticals, in-line monitoring and control are
essential. Many pharmaceutical manufacturing processes require pH adjustment. Here, an …

In this paper, a new model free adaptive control method based on self-adjusting PID
algorithm (MFAC-SA-PID) is proposed to solve the problem that the pH process with strong …

This paper presents the state-of-the-art of the artificial intelligence algorithm, named dual
heuristic dynamic programming (DHP) that uses to solve the petroleum optimization-control …
