TotalEnergies and partner QatarEnergy have entered into an agreement to acquire participating interests in Block 3B/4B, offshore South Africa, from Africa Oil South Africa, Azinam (a wholly owned subsidiary of Eco Atlantic Oil and Gas), and Ricocure. Following completion of the transaction, TotalEnergies will hold a 33% participating interest in Block 3B/4B and assume operatorship, while QatarEnergy will hold a 24% interest. The remaining interests will be held by existing license holders, Africa Oil SA (17%), Ricocure (19.75%), and Azinam (6.25%). The transaction is subject to final approvals from relevant authorities. The farm-in deal offers a maximum transaction value of up to 46.8 million to Africa Oil.

Knowing where to start can be daunting for those new to the oil and gas industry. With all the changes the artificial lift sector has experienced in the past 25 years, the constant is that a new challenge always needs a solution. The spirit of innovation and invention will serve the next generation of artificial lift professionals well. Here are a few nuggets of advice from experts to help newcomers navigate this dynamic sector while also making a difference in the energy world. My advice is to go for it!
Upon completion of this module, the participant should be able to identify reservoirs that are suitable candidates for horizontal or multilateral wells, apply knowledge of the reservoir to a selection of the well trajectory, and select the best general completion design for a horizontal or multilateral well in a given reservoir.
Ensure that logging and testing operations proceed smoothly. Upon completion of this module, the participant should be able to: prepare the well for open-hole logging operations and take steps to ensure that such operations proceed smoothly, alert the wellsite geologist and service company logging engineer of hole conditions that may require modifications or special precautions in the logging program, assist in planning and carrying out a drill stem test, determine safe operating parameters for running a production casing string, plan and carry out a simple single-stage primary cementing operation, use temperature surveys to determine the top of cement in the casing/hole annulus, and outline the steps involved in preparing the well for final completion and releasing the drilling rig.
This short course provides a broad, basic understanding of various petroleum engineering topics for non-petroleum engineers. The focus of the course is placed on the design, construction, stimulation, and production of wells, both vertical and horizontal. Specific topics discussed include reservoir properties, fluid flow behavior, the drilling of wells, rig types, wellbore integrity and design, completion types, downhole tools such as packers, formation damage, stimulation including hydraulic fracturing, and artificial lift techniques. As the title implies, the course is designed for those who work in the oil and gas industry but do not have a technical background in subsurface topics. Previous attendees that have found the course useful include geologists, geophysicists, landmen, technicians, accountants, financiers, lawyers and field personnel.
Diamondback Energy has announced its acquisition of Permian Basin rival Endeavor Energy Resources in a cash-and-stock deal valued at approximately 26 billion. The consolidation will create a firm worth almost 60 billion. It also underscores the recent shake up of the US shale sector, following a year in which mergers and acquisitions topped 192 billion, with an additional 40 billion occurring in this quarter alone, according to figures from Enverus Intelligence Research (EIR). The trend underscores the drive of large operators to add significant volumes of flowing barrels along with untapped drilling locations to secure long-term viability. Prior to today, Diamondback itself has made more than 4 billion in other cash-and-stock deals to enhance its drilling inventory and cash flow from mineral rights since 2022.

_ This article, written by JPT Technology Editor Chris Carpenter, contains highlights of paper URTeC 3871303, “Using a Multidisciplinary Approach to Reservoir and Completion Optimization Within the Woodford Shale Play of the Arkoma Basin,” by Stephen C. Zagurski, SPE, and Steve Asbill, SPE, Foundation Energy Management, and Christopher M. Smith, Advanced Hydrocarbon Stratigraphy, et al. The paper has not been peer reviewed. _ Subsurface complexities related to the formation of peripheral foreland basins can have significant effects on unconventional resource development. In the Arkoma Basin of southeast Oklahoma, the onset of thrusting and tectonic loading induced a complex series of dip/slip and strike/slip faults during basin formation. The operator used a series of technologies to increase understanding of the reservoir and its hazards and provide insight into economic implications for future development plans and strategies. Introduction The Woodford is primarily a Type II kerogen source rock. The formation typically is classified as either siliceous mudstone or cherty siltstone. Variable thermal maturity across the basin places the Woodford in both the wet-gas and dry-gas phase windows (moving west to east across the basin). Complex faulting regimes within the Arkoma add a layer of complexity to horizontal development of the Woodford. The operator wanted to increase the understanding of the Woodford and the effects of faulting through the reservoir in a recent development unit in the liquids-rich fairway. The development unit consists of an existing parent well (Well X) and a pair of child wells (Well Y and Well Z). The background of Unit XYZ begins with the completion of parent Well X 4–6 years before infill development. In this portion of the basin, Well X’s initial production rate and its cumulative production to date rank it in the top 25% of wells. The wellbore is subjected to a pair of faults and was drilled in the upper half of the Woodford. Placement of Well X is substantially further east than most parent wells because it is approximately 1,600 ft from the unit boundary. This limited infill development to two wells instead of three; the Arkoma typically has seen spacing of four, and sometimes five, wells per section. Wells Y and Z were planned and drilled east of Well X with 1,100–1,600 ft of well spacing. Well spacing in the unit was slightly hindered by surface location limitations and limited true vertical depth (TVD) between surface casing and landing point. Structural complexity within the unit partially impaired infill development of the unit. Specifically, Well Y and its lateral length was shortened. In this portion of the Arkoma, fault-derived water production typically is the highest-weighted variable in a well’s operating expenditure. Thus, the ability to limit excess water production within Unit XYZ and the surrounding acreage is of paramount importance.
