One of the quieter decisions on a drilling programme is whether to own the solids-control equipment or rent it — usually with a service crew attached. It looks like a finance question, capital against day-rate, but it isn’t really. The number that decides it is not on the rental invoice; it’s whether the equipment is actually operated to perform. A cheap rental run badly costs far more in dilution than an expensive one run well. Here is how the two models actually compare.
The two models
Owning means the operator or drilling contractor buys the shakers, cyclones and centrifuges as capital, then staffs, maintains and consumables them. The appeal is the obvious one: on a long campaign with steady utilisation, spreading a purchase over many wells beats paying a day-rate that never stops, and you control your own screens, spares and standards. The exposure is equally clear — capital tied up, maintenance and obsolescence on your books, and the need for competent people to run it, because equipment you own but don’t operate well is the worst of both worlds.
Renting, most often as an operated service, bundles the hardware with a trained crew, maintenance, screens and technical support for a day-rate. You convert capital into opex, you get current equipment and expertise without carrying either, and you can scale up or down per well. The exposure is that the meter runs continuously and, over a long high-utilisation programme, a day-rate can quietly exceed what ownership would have cost. Weighing utilisation, campaign length and in-house competence against those trade-offs is exactly the kind of decision Rig IQ helps frame.
The cost that isn’t on the invoice
Here is the trap in comparing the two on price. The rental line item or the depreciation schedule is the visible cost — and it’s the smaller one. The cost that dominates is performance: whether the train is operated so that it actually removes solids, or whether it runs while dilution quietly carries the load it should. A poorly run system — wrong screens, bypassed cyclones, a centrifuge left off — bleeds far more in built-and-discarded mud than the difference between owning and renting the box.
That reframes the whole decision. The right question isn’t “which is cheaper to have” but “which gets the equipment operated to perform on this programme.” For an operator without in-house solids-control expertise, an operated rental with a competent crew often wins precisely because the service, not the steel, is what protects the mud budget. For a contractor with skilled people and steady work, ownership can win. Judging it on delivered performance rather than the rental rate is the shift Rig IQ is built to support.
Choosing the model
The decision comes down to a few honest questions. How long and how steady is the utilisation — a short or intermittent programme favours renting, a long high-utilisation one can favour owning. Do you have the in-house competence to operate owned equipment to standard, tour after tour, or would you be buying a box you can’t run? What’s the appetite for capital versus opex, and for carrying maintenance and obsolescence risk? And what’s the cost of getting it wrong — on a tight-margin, sensitive well, the assurance of an operated service can be worth more than the day-rate.
Whichever model you pick, the governing metric is the same: cost per foot, fully loaded with the dilution and disposal the system’s performance drives. Own or rent, the equipment only pays if it’s run to remove solids — so the model is really a question of which arrangement delivers that on your particular programme. Putting delivered performance, not the rental rate, at the centre of the choice is exactly what Rig IQ is designed to do.
Owned vs rented, in short
Own: capital purchase, you staff/maintain/consumable it. Wins on long, steady utilisation + in-house competence. Risk: capital, maintenance, obsolescence, and needing people to run it well.
Rent (operated): hardware + crew + maintenance + screens for a day-rate. Wins on short/variable programmes or no in-house expertise. Risk: the meter never stops.
The real cost isn’t the invoice — it’s whether the equipment is operated to perform. A cheap system run badly loses more in dilution than the rental gap.
Decide on delivered cost per foot, not the rental rate.
Owning solids-control equipment (capital, you staff and maintain it) tends to win on long, steady programmes where you have in-house competence to operate it well; renting it as an operated service (hardware plus crew plus maintenance for a day-rate) tends to win on short or variable programmes or where in-house expertise is thin. But the decisive cost isn’t the rental line or depreciation — it’s whether the equipment is operated to perform, because a poorly run system loses far more in dilution than the difference between the two models. Decide on fully-loaded cost per foot, not the rental rate.
Common questions
Is it better to own or rent solids-control equipment?
It depends on utilisation and in-house competence. Owning tends to pay on long, high-utilisation programmes where you have skilled people to operate the equipment well, because spreading a purchase over many wells beats a continuous day-rate. Renting — usually as an operated service with a crew — tends to pay on short or variable programmes, or where you lack in-house expertise, because you get current equipment and skilled operation without tying up capital.
What is operated solids-control rental?
It is a rental model where the hardware comes bundled with a trained crew, maintenance, screens and technical support for a day-rate. Rather than just renting the equipment, you rent the equipment plus the people and service to run it. This is often the better choice for operators without in-house solids-control expertise, because the service — not the steel — is what keeps the equipment performing and protects the mud budget.
What is the biggest cost when choosing a solids-control model?
Not the rental invoice or the depreciation — those are the visible, smaller costs. The dominant cost is performance: whether the equipment is actually operated so that it removes solids, or whether it runs while dilution quietly carries the load. A poorly operated system loses far more in built-and-discarded mud than the difference between owning and renting, so the decision should be made on fully-loaded cost per foot, not the rental rate.
