Drilling Fluid Systems
1. Drilling fluid being ‘the blood of the drilling process’ essentially relates - either directly or indirectly - to ‘the problems or solutions’ of wellbore instability; lost circulation; kicks and blowouts; and ‘stuck pipes’.
If so, whether the ‘drilling fluid’
‘deduced @ laboratory-scale using experimental conditions’
actually remains to be an ‘architect’
that can make ‘the drilling operation’
‘in a real field scenario’
either to ‘materialize’ or ‘unrealizable’?
2. As we know, although, drilling fluids might represent only 5-15% of drilling costs, it may however cause 100% of drilling problems.
In this context, can we efficiently bring in machine-learning/artificial-intelligence in order to deduce an optimal selection of drilling fluids?
3. How best can we make use of ML/AI in order to go ahead with ‘design and analysis of drilling fluid data’ in order to deduce ‘optimal’ solution?
And, whether the data grabbed from previously drilled wells in the associated areas would suffice?
For example, how exactly AL/MI would try to grab and analyze ‘field’ data on the type of drilling fluid; fluid constituents;
fluid rheology;
fluid density;
filtration and other fluid properties and
fluid’s maintenance requirements?
OR
AL/ML would try to design the drilling fluids
by trial and error (as we do in the laboratory with our smart initial guesses?
4. How exactly the application on ‘clay free drilling fluid’ remains to be better and dominant over ‘other high-efficiency drilling fluid technologies’ (that have been developed worldwide) such as
‘high-temperature and high-density oil-based’;
‘soil-free oil-based;
high-performance water-based;
bionic high-efficiency water-based; and
amphiphobic high-efficiency water-based drilling fluids?
Feasible to defend our reasoning - with reference to increasing complexities faced by drilling projects – as a function of:
(a) shallow to deep/ultra-deep layers;
(b) from conventional to unconventional resources (such as CBM, NGH, oil shale, tight oil & gas, shale oil & gas);
as well as
(c) from traditional fossil energy to new energy sources (such as hot dry rock)?
5. How do we, in general, consider the ‘selection of drilling fluid types and treatment agents’; and ‘drilling fluid formulations and performance design’ – towards mitigating the wall stability; sticking, lost circulation; reservoir damage and environmental pollution – by precisely predicting
(i) the formation temperature and pressure;
(ii) the formation rock composition and structure;
(iii) the formation fluid properties and distribution;
(iv) the potential damage factors and critical points of the reservoir; and
(v) the technical difficulties and complexity that may be encountered during drilling
@ laboratory-scale using experimental observations?
