David Semwogerere holds a BSc in electrical engineering (honors, 2012) from Makerere University in Uganda. In 2012, he started work as a junior well testing and completions engineer at Total. His work involved well test design and execution and working with well engineering modeling and drilling parameter software. He was also a nightshift well test supervisor for Total in the upper west Nile exploration and appraisal campaign on four workover rigs. Semwogerere later moved to the China National Offshore Oil Company in 2014 as a well completion engineer in the Kingfisher Albertine exploration region on Lake Albert.
Zainab Titus holds a B.Eng. with First Class Honours from Covenant University, where she graduated as the most outstanding Petroleum Engineering Student in 2015. Owing to her interest in Physics and the numerous awards she had won in Mathematics Competitions locally and nationally during her secondary school days, it was not difficult to identify her predisposition to engineering. Zainab developed a predilection for Petroleum Engineering when on a road trip, she was fascinated by the sophisticated equipment and technology used for oil prospecting activities in the Chad basin of Nigeria. Zainab's engagements with SPE International began in 2013 through her University Student Chapter, where she served as the Technical Officer in 2014. She also interned with ExxonMobil Nigeria and the Nigerian National Petroleum Corporation (NNPC) in 2014, where she worked on projects related to well testing, annular pressure build-up analysis and petroleum economics.
Some well-testing operations are executed by performing multiple runs in hole using slickline and coiled tubing (CT). A technology has been developed that combines many of these operations, including contingency stimulation activities, into one run. A type curve is a quick way to answer a critical question—what does a typical well produce over time in a given place?
For the past 20 years, the diagnostic fracture injection test has been used across the frontlines of the shale revolution to paint a picture of what cannot be seen. However, that picture has not always been so clear in the eyes of subsurface engineers. Operators are working with a young startup company to overhaul how the unconventional sector has traditionally interpreted one the most common tests used to influence well completion designs.

Range Resources' drilling head talks about how the company went from drilling the shortest laterals in the Marcellus to the longest and why. Rapid Evaluation of Development Ideas Has Engineers Thinking: What If? A software program has evolved from predicting future well output to showing engineers the many ways their ideas could affect asset performance.
Listen as some of the oil and gas industry's most significant contributors discuss the impact that innovation and technology have made in meeting the challenges of producing energy faster, cheaper, and safer in the 20th century. Dr. Gringarten holds the Chair of Petroleum Engineering at Imperial College in London, where he is also director of the Centre for Petroleum Studies. He has made major contributions in many breakthrough advances in well test interpretation, including: the use of Greens functions; the "Gringarten type curves" for wells with wellbore storage and skin, fractured wells, and wells with double porosity behavior; the first major commercial computer-aided interpretation software; and a well-test interpretation methodology which has become standard in the oil industry. He was also an early pioneer of multidisciplinary studies, both in industry and in academia. He was responsible for the development and world-wide implementation of well test interpretation services and was in charge of PVT laboratories at Flopetrol-Schlumberger in Melun, France. Dr. Gringarten is a recognized expert in well test analysis and has authored or coauthored more than 80 technical papers. World renowned for his work in well control, Bill Rehm developed well control and pressure measurements from electric logs.
Some well-testing operations are executed by performing multiple runs in hole using slickline and coiled tubing (CT). A technology has been developed that combines many of these operations, including contingency stimulation activities, into one run. A project spearheaded by ExxonMobil, Shell, Chevron, and the Southwest Research Institute (SwRI) has been established to advance separation technology through improved testing methods and collaboration between users and suppliers. The simplest way to measure return on investment for an offshore water treatment system is to determine whether using the system actually reduces the risk of paying a fine for violating water pollution laws.
For the past 20 years, the diagnostic fracture injection test has been used across the frontlines of the shale revolution to paint a picture of what cannot be seen. However, that picture has not always been so clear in the eyes of subsurface engineers. Expected to close 31 October, the deal will create one of the largest pressure pumpers in the US.
A single-well polymer-injection and back-production test has been performed in an oil and gas field offshore Norway. The objective of the test was to verify at field conditions the properties measured in the laboratory for the biopolymer schizophyllan. Continued enthusiasm in the well-testing segment of the oil industry is apparent. Even though there was a smaller number of presentations among various conferences related to well testing in 2016, there are articles that contribute significantly for the experts and the upcoming generation. The application of high-precision downhole temperature sensors has resulted in pressure-transient analysis (PTA) being complemented or replaced by temperature-transient analysis (TTA).
P-68 is Petrobras’ fourth FPSO to begin operations this year following the startups of P-67 at the Lula field and P-76 and P-77 at the Buzios field. Chinese firms stepped in for the majors in Brazil’s two underwhelming offshore auctions. The round included a near-$1 billion signature bonus on a Campos Basin block awarded to a Total-led consortium. Petrobras and Shell have brought online the Lula field’s seventh FPSO as the firms continue to ramp up production from the pre-salt Santos Basin. The paper provides a fast-track approach to perform screening assessment of multiple subsea concepts.
