What To Do When RSS Is Not An Option Due To Tight Budget

A Case For Side-track Campaign with Motor BHA By: Erwan de Boisjolly Context An Operator is planning a side-track campaign on approximately 20 wells. As they want to reduce equipment’s costs -avoiding expensive RSS- they want to assess if these wells can be drilled with steerable motor BHA. The Operator contacted DrillScan to perform some […]

How To Place These Non-Rotating Protectors To Keep Your Casing in Safe Zone

A Casing Wear Study in HP/HT Well By: Florent COULIOU   Context High doglegs were present along an accidental nudge interval in vertical section (up to 3.5°/100ft DLS) of the well, resulting in potential critical level of wear along the 14” production casing. The operator’s maximum wear budget for this casing string being 15%. To […]

How To Run Mixed Lower Completion String To Bottom in Deepwater Extended-Reach Well

By: Florent COULIOU This ERD well in a Deepwater field has reached TD after 22 days. Tens of millions of dollars have been spent already. Now comes the tricky part: running the lower completion string. This is to connect the wellbore to the reservoir. If something goes wrong, those tens of millions of dollars will […]

How to get out of a predicament of an unexpected side-track

A geothermal well doublet producing from a 75°C aquifer, had been operated for over 29 years. The last calliper run performed to control the ID of the 9 5/8” casing indicated there was corrosion and sediments clogging the inner side walls of the injector well, which was hindering production. To regain well integrity, a workover was performed to clean out the 9 5/8” casing in order to reline it. During the workover operations, a cement squeeze-flash occurred causing the 3 ½” drill string being stuck in hole. Remedial operations using coiled tubing was stopped after over two weeks of unsuccessful attempts. The injector well was then suspended with a cement plug set on top of the fish.

Horizontal and Complex-Trajectory Wells

With the long-term price of a barrel of oil projected to hover around $50, all actors in the oil and gas industry have been forced to change or adapt their processes to try to reduce costs and sustain profitability. Accompanying the downturn, the oil and gas industry has entered a new era of digitalization, introducing new buzzwords to our industry such as artificial intelligence, digital twin, machine learning, neural network, industrial Internet of Things, and cloud computing, just to name a few.
