managers, geologists, drilling engineers, and directional
Dr. Eric Maidla, Slider LLC (http://www.slidercorp.com/),
course provides an introduction to the nomenclature and equipment
used to drill conventional, directional, and horizontal wells
and explore ways to enhance the drilling efficiency while
sliding to make a trajectory correction.
for the participants to understand the effectiveness of the
different options to enhance the drilling performance there
will be a detailed explanation on how torque and drag work
in the wellbore and ways to mitigate their negative effects.
will present new ways to drill directional and horizontal
wells and it will address in detail the cost issues involved
with each different system presented.
to the risks of the different systems will also be addressed
and ranked according to a ranking process that will be built
with the active input of all participants.
new techniques that will be presented will demonstrate
the possibility of:
the tool face without having to come off bottom while
sliding (today this is not possible). This is very important
to CBM that is quite a soft medium compared to traditional
petroleum drilled rocks and any orientation off bottom
wipes out trajectory corrections quite easily.
how the rocking movement of the pipe (small rotations
to the right and left) can help in the sliding process
in the conventional, directional, and horizontal drilling
how to optimize the use of power swivels or top drives
to enhance the directional drilling operation.
differential sticking effects while sliding.
a process to smoothly transfer weight to the bit.
Eric Maidla is the Business Development partner of Slider
LLC, a company involved in automation of the directional drilling
process with the aim to enhance drilling efficiency. He is
also the President of Genesis Lone Star LLC a company devoted
to drilling analysis and marketing of Genesis, a technology
owned by the Australian government, Commonwealth Scientific
and Industrial Research Organization (CSIRO), . He has authored
over 50 papers/publications/book chapter, and currently has
been granted 2 patents and has another 3 pending. Some of
his major accomplishments include (1) founding the Petroleum
Engineering Department at the State University of Campinas
in Brazil in 1988; starting the Genesis project for CSIRO
in Drilling Data Management (1995-2001); and the conception,
management, and development of new directional drilling technology
for Noble called Slider (2001-2004).
