Steering & drilling services

Lucas differentiates itself from other drillers through its expertise in design, extended reach medium radius drilling (MRD), underbalanced drilling, directional downhole instrumentation, real time data analysis and collection, plus other technology advancements offered by our Directional Services team.

Lucas has developed its own Lucas Steering System (LSS) with the highest number of measured parameters in Australia. It is the leader in the field for data rates, data quality and data accuracy.

Lucas offers the following services:

Field rental equipment

• EM measure while drilling (MWD) tool rental
• Pressure while drilling (PWD) real time and memory tool hire
• Down hole wireline MWD tool rental
• AC surface ranging beacon hire
• TruTrak surface ranging equipment hire
• Macktrack vertical well ranging equipment hire.

Field personnel

• Technicians to operate the above systems
• Technicians for coal bed methane directional drilling (internal and external)
• Technicians for civil applications of horizontal directional drilling (internal and external)
• Technicians for vertical and deviated production wells
• Drilling engineers for real time logging and evaluation of drilling curves against torque and drag models
• Supervisors and trainers for the above field activities.

Engineering services

Internal and external services provided by drilling engineers and inhouse geologists include:

• Reservoir development studies
• Drilling feasibility and detailed drilling engineering studies
• Torque and drag modelling – tubular running, casing, drilling and product pipe installation
• Product pipe stress calculation and design
• Hydraulic modelling – single phase and multi phase flow regimes
• Underbalanced drilling simulation and engineering
• PWD data interpretation
• Reservoir modelling
• Geological interpretations
• Geological model development – logging, coring and seismic interpretation and formation evaluation
• Geological and mine model development and upkeep
• Well engineering and design (casing, geometry, cementing)
• Bottom hole assembly (BHA) analysis, design, optimisation.

Well services

• Design, procurement and installation of coal seam methane equipment in both CMM and CSM applications in Queensland and NSW
• Monitoring of gas wells
• Construction of surface facilities for underground gas drainage
• Monitoring of gas production equipment and commissioning of control  and automation systems
• Implementation and compliance with gas drainage models and production drawdown curves
• Design, procurement and installation of tubular and electric submersible pumps for coal seam dewatering which initiates gas flows
• Design, procurement and installation of gas gathering lines and flare construction
• Installation and maintenance of down hole production pumping equipment
• Flushing of lateral drainage holes in which flow is impaired  to increase gas production
• Cleaning out of vertical production wells in which frac sand has impeded the flow of gas into the wellbore by the use of reverse circulation technology.
