Production drill rig optimisation

By considering the entire workflow from the perspective of a production system, this paper presents a method to optimize drill rig fleet size and schedule that considers both reservoir management and operational objectives, namely maximizing production volume, meeting production targets and/or minimizing drilling and completion costs.

FAQS about Down-the-hole drill basket production video

What is a down-the-hole drill?

A down-the-hole drill, usually called DTH by most professionals, is basically a jackhammer screwed on the bottom of a drill string. The fast hammer action breaks hard rock into small cuttings and dust that are evacuated by a fluid (air, water or drilling mud). The DTH hammer is one of the fastest ways to drill hard rock.

What is down-the-hole (DTH) drilling?

Down-the-hole (DTH) drilling has made it easier for contractors to drill wells faster and more efficiently, and to transition from dirt boring to rock boring just by adding a compressor and hammer to the drill bit.

What are the advantages of using down-the-hole drilling tools?

The advantages of using down-the-hole drilling tools are numerous. They offer faster penetration rates and lower energy consumption compared to other methods, making them ideal for large-scale projects. Additionally, DTH drills are versatile and can be used in a wide range of geological formations, from soft soil to hard rock.

What makes a DTH drill system different from other drilling systems?

The advent of tungsten carbide for the drill bits (the first bits were all-steel) and the development of the button drill bit coupled with the introduction of high air pressures (25 bar plus) has meant that the DTH system can compete easily and efficiently with other drilling systems.

How does a down-the-hole hammer work?

The down- the-hole hammer uses the rotary percussion cutting action through the use of a button bit. This system is best suited for well consolidated formations, offering excellent penetration rates. Compressed air provides the percussive energy to power the hammer. The resulting exhaust removes the cuttings. Note the quality of the cuttings.

Us oil drilling rigs decline

The total rig count in the US slipped to 536, according to Baker Hughes, down 47 from this same time last year. The rig count is still near four-year lows. The number of oil rigs rose by 1, landing at 412. Year over year, this represents a 71-rig decline.. The total rig count in the US slipped to 536, according to Baker Hughes, down 47 from this same time last year. The rig count is still near four-year lows. The number of oil rigs rose by 1, landing at 412. Year over year, this represents a 71-rig decline.. The total number of active drilling rigs for oil and gas in the United States fell again this week, according to new data that Baker Hughes published on Friday. The total rig count in the US slipped to 536, according to Baker Hughes, down 47 from this same time last year. The rig count is still. . The US energy sector has witnessed a significant shift in drilling operations, with the latest Baker Hughes report revealing the first decline in oil and gas rigs in three weeks. According to the report, the total rig count fell by one to 592 in the week ending March 28, 2025, marking a notable. . A recent report released by Baker Hughes shows that energy companies in the U.S. continue to reduce the numbers of natural gas and oil rigs in operation, signalling a continued slowdown in drilling activity. This past week, the natural gas and oil rig count fell to 539, its lowest number since. [pdf]
