Africa (Sub-Sahara) Bowleven said that its extended flow test program at the Moambe and Zingana wells on the Bomono Permit onshore Cameroon is complete. The company said that the results to date continue to support its plans for an initial supply of between 5 MMscf/D and 6 MMscf/D of natural gas for power generation, under a development program established with partners Actis and Eneo. The initial program focuses on production from the shallower gas-prone sands on the permit. Bowleven has a 100% equity interest in the permit. Eni started production from the West Hub development project's Mpungi field in Block 15/06 offshore Angola. The startup follows the project's first oil from the Sangos field in November 2014 and the Cinguvu field last April.
The single independent riser (SIR) is a hybrid riser configuration optimized for ultradeepwater field development. The SIR is composed of a flexible jumper and a rigid part vertically tensioned by means of distributed or continuous buoyancy. This paper describes an automated work flow that uses sensor data and machine-learning (ML) algorithms to predict and identify root causes of impending and unplanned shutdown events and provide actionable insights. The Monument well represents the Norwegian operator’s first deepwater drilling project in US waters in 5 years. Transocean reported a long list of reasons why the deepwater drilling business is coming back strong.
Africa (Sub-Sahara) Kosmos Energy has made a significant deepwater gas discovery off Senegal. The Guembeul-1 well in the northern part of the St. Louis Offshore Profond license in 8,858 ft of water encountered 331 net ft of gas pay in two excellent-quality reservoirs, the company reported. The results demonstrate reservoir continuity and static pressure communication with the Tortue-1 well, which suggests a single gas accumulation. The mean gross resource estimate for the Greater Tortue complex has risen to 17 Tcf from 14 Tcf as a result of the Guembeul discovery, the company said. Kosmos, the operator, has a 60% interest in the well. Timis (30%) and Petrosen (10%) hold the remaining interest.
Are fugitive releases of natural gas and flaring environmental concerns? Can these be ameliorated today and even better in the future? What Is All This Talk About Emissions? Emissions are in the air and in the headlines every day. With growing regulations around all types of air emissions, are there ways that industry can deploy technologies cost-effectively in the current environment?
The complete paper presents a case study in which offline cementing improved operational efficiency by reducing drilling times and provided significant cost savings. The data analytics firm projects US dry gas output growth will shrink to 2 Bcf/D next year from 8–9 Bcf/D in 2018 and 2019. The complete paper describes a recent directional coiled-tubing drilling (DCTD) job completed for an independent operator in the Appalachian Basin.
Africa (Sub-Sahara) Tullow's Cheptuket-1 well in Block 12A of northern Kenya has encountered good oil shows over an almost 2,300‑ft interval, the company reported. The first well to test the Kerio Valley Basin, Cheptuket-1 was drilled to a final depth of 10,114 ft. The results indicate the presence of an active petroleum system with significant oil generation, the company said. Post-well analysis now under way will affect future basin exploration decisions. Tullow is the block operator with a 40% interest. Delonex Energy (40%) and Africa Oil (20%) are the other participants.
Africa (Sub-Sahara) Petroceltic International said that the first of up to 24 new development wells planned in Algeria's Ain Tsila gas and condensate field was successful. The AT-10 well, situated about 2 miles from the AT-1 field discovery well, reached a total depth of 6,578 ft. Wireline logs indicated that the expected initial offtake rate would be comparable to the AT-1 and AT-8 wells, both of which test-flowed at more than 30 MMcf/D. Petroceltic is the operator with a 38.25% interest in the production-sharing contract that covers the Ain Tsila output. The remaining interests are held by Sonatrach (43.375%) and Enel (18.375%). Sonangol reported that it has found reserves in the Kwanza Basin of Angola that could total 2.2 billion BOE, including reserves in a block jointly owned with BP. Block 24, operated by BP, holds an estimated 280 million bbl of condensate and 8 Tcf of gas, totaling 1.7 billion BOE, Sonangol said in a statement seen by Reuters.
In addition to the well-recognized elements of digital transformation such as real-time monitoring, remote intelligence, and extraction of insights from data, there is a need to evolve the industry hardware through application of enhanced edge computing. Unlike shale, deepwater plays—which are highly front-loaded investments with long project cycles—will be least affected by the current round of severe investment reductions. Large offshore plays in safer regions have become essential elements of the core business of large oil and gas players. In 2004, US oil production was in decline, Facebook did not exist, and attitudes toward climate change were in flux. Despite the global downturn, the long-term transition to net zero presents a major opportunity to create new multibillion industries based around the North Sea. Cross-sector collaboration and major state/private sector intervention, together with strong leadership, will be key.
InfraStrata has spudded the Woodburn Forest-1 well in County Antrim in Northern Ireland, the United Kingdom. With a planned well depth of 6,561 ft, the drilling targets three conventional sandstone intervals. P50 prospective resources targeted by the well are estimated at 25 million bbl of oil. After drilling, the well will be plugged and abandoned and the site will be restored to its former state. Should results be favorable, additional consent and plan approval will be needed for further activity such as testing.
A description of the role of effective reservoir management in increasing the recovery factors for unconventional reservoirs, and a review of the advances in IOR/EOR technologies for unconventionals, as performed by the Energy Industry Partnership Team at the University of Houston. Detection and identification of the type and intensity of frac-driven interactions is the key to the next generation of fracturing operations. Occupational diseases of employees can have a significant impact on workplace productivity and exact an unmeasurable emotional and financial toll on the workers and their families. It is important to design programs that will put the workplace on a journey toward prevention of diseases. Is There a Need for a Reserves Confidence Metric?
