It takes an average of 7 days to drill through the Travis Peak formation in the southern Haynesville basin. The objective of this paper was to improve the rate of penetration (ROP) and therefore reduce the time taken to drill through this formation. Machine learning and regression models were applied to electronic drilling record data and identified that the auto-driller ROP setpoint was the most influential variable ROP for wells drilled in the Travis Peak formation. This finding was corroborated during field visits with well site leaders and drillers with the discovery that ROP was being used as the controlling setpoint in the auto-driller system for drilling in the Travis Peak and Calvin Sand formations.
After discussion with the rig provider, a new set of auto-driller parameters was proposed using weight on bit as the controlling setpoint with the objective of increasing the rate of penetration. The new auto-driller parameter roadmap was piloted on two wells.
ROP performance for these two wells was significantly better than the nearest offset and other offsets in the nearby area. The drilling team estimate about two days per well time saved as a result of the improved ROP.
With US oil prices struggling to top $25, oil companies and service providers are making deeper cuts this month to cope. The biggest come from Halliburton which may have shed 5,000 total jobs since the start of the year. Anchored by the Khaleesi-Mormont and Samurai fields, the King’s Quay FPS will receive and process up to 80,000 B/D of crude oil. Murphy Oil to Buy Deepwater US Gulf Assets for up to $1.625 Billion The El Dorado, Arkansas-based Murphy has quickly found a home for some of the cash it will receive from the sale of its Malaysia business. The company has been rapidly expanding its US gulf footprint while simplifying its portfolio and targeting more oil.
Murphy Oil to Buy Deepwater US Gulf Assets for up to $1.625 Billion The El Dorado, Arkansas-based Murphy has quickly found a home for some of the cash it will receive from the sale of its Malaysia business. The company has been rapidly expanding its US gulf footprint while simplifying its portfolio and targeting more oil. The pact, which builds on the firms’ current partnership on the Buckskin project, covers four Keathley Canyon blocks including the Leon and Moccasin discoveries. BP announced four discoveries in the Gulf of Mexico near existing platforms. It use advanced seismic imaging to identify resources in deepwater locations that can be developed cost effectively using platforms nearby.
Saudi Aramco and university researchers are experimenting with a thermochemical fracturing fluid that aims to eliminate more than half of the pumping horsepower typically required to complete horizontal wells. Advanced machine-learning methods combined with aspects of game theory are helping operators understand the drivers of water production and improve forecasting and economics in unconventional basins. Two places that illustrate the mounting challenges facing the shale business are the Bakken Shale in North Dakota, where the number of working rigs is one-third what it was a year ago, and the Fayetteville Shale in Arkansas, where there are no more working rigs. An analysis of thousands of fracturing treatments in major plays in the United States provides insights into how fracture designs have changed over time.
In 2 months, the US saw a 56% decline in rig count, reaching a 33-year low. A marked change from a decade ago, Appalachia, the Permian, and the Haynesville now represent almost half of total US gas production, EIA reports. BP To Buy US Shale Assets From BHP for $10.5 Billion BP ends a year of speculation as to who will buy BHP Billiton’s much-coveted US unconventional business, transforming its Lower 48 portfolio in the process. Drilling and completion expenditure and activity is projected to show multiyear double-digit growth from 2018–2022 despite a flattening of rig count increases. After a drop in drilling activity in recent years, the Haynesville shale has become a hot area for natural gas production in the US, and companies are looking to bolster their positions in the area.
